Ashford Hill near Thatcham is not served by foul mains drains adequate enough to process the waste water from 35 new houses, connection to Thames Water was fully investigated and costed via a section 98 requisition application which provided a 7 figure sum that made the development costs nearly £50,000 per plot for foul waste treatment alone.

Initially the developer Persimmon Homes appointed Advanced Aeration Ltd to act as Agent with the task of gaining an Environmental Permit to discharge biologically treated sewage into the local brook. The Environment Agency has a duty to determine the likely impact on receiving waters which necessitated us providing detailed annual flows expected within the Brook as historically and at the time of testing zero flows were experienced, meaning at certain times of the year little or no dilution of the final effluent from the site could be expected, this was naturally a concern to local residents who over time had historically experienced problems related to other local sewage treatment plants. It therefore took around a year to fully satisfy the Environment Agency that Bio-Bubble did indeed represent an environmentally sustainable solution.

The Discharge was permitted to Baughurst Brook, a small water course that can dry up at certain times in the year. The determination outcome was a numerical standard with absolute maximum levels for BOD of 15mg/l, Suspended solids of 30 mg/l and ammonia of 5mg/l; safe to say one needs the plant to perform far higher than those levels to have a sufficient buffer within the legal compliance requirement, the Baughurst Brook passes through a SSSI so it was very important to mitigate the risks of plant / equipment and indeed process failure.

Process monitoring and plant management are key and similar to many of our client’s sites we have a monitoring package to be forewarned of pending issues. For a development such as this we use a 4G network connection to keep a close watch on day to day functionality, trending flows and loads, effluent clarity and sludge production. The process comprises of Biological screening, primary tank mixing, full biological treatment and attenuation of final effluent.

Bio-Bubbles renowned ability to digest organic loads leads to a lower carbon footprint, significantly reducing the need for regular tanker visits to site to cart primary sludge’s away, thereby keeping tanker traffic on small local village roads to the minimum.

Blaze Construction, a Persimmon Homes civils partner were appointed to carry out the related groundwork’s for the installation of the Bio-Bubble STP.


“Kingston Country Courtyard | Dorset Wedding Venue”

KCC wedding venue

Kingston Country Courtyards design specialist weddings to meet their client’s needs, the venue is within a tastefully renovated 16th century Purbeck stone barn located south of the famous Corfe Castle ruins.

The venue can cater for 130 seated guests at a reception with room for 175 attending the evening do and has 26 double rooms for the wedding party to stay.

More Info

Most venues can hold two or three weddings a week during the peak season producing a lot of waste water on the day of the event, the Bio-Bubble being a Sequenced Batch Reactor can flatten out those daily peaks and troughs over the whole week matching the amount of treatment to the amount of waste produced, thus only using the energy needed rather than running 24 / 7 regardless. At quieter times of the year when it may only be the bed and breakfast accommodation in use the plant will adjust to this; indeed in low season the system can select Sleep mode on days when little or no waste is produced, lying ready and available to perform when the waste arrives. Once treated the waste keeps the old ponds topped up before leaving site to make its way down to the Corfe River.
The Bio-Bubble system does not only process the liquid like many package treatment options available; therefore primary sludge’s are not separated and stored for removal by tanker so one need not worry about odours leaving a septic primary tank and lingering locally.
The drainage and civil works for this project were undertaken by Jerry Lloyd of local waste water treatment firm Drainage 2000 Ltd.


“ZSL Whipsnade Zoo’s | Base Camp Restaurant”

Founded in 1826, the Zoological Society of London (ZSL) is an international scientific, conservation and educational charity whose mission is to promote and achieve the worldwide conservation of animals and their habitats.

ZSL have a program of investment to improve the visitor experience at their 600 acre Whipsnade zoo site. The Bio-Bubble has been installed to treat the waste from the Base Camp Restaurant formerly known as the Lookout Cafe prior to refurbishment and opposite the Zoo’s incredible white rhinos, this newest eatery opened in partnership with celebrity chef Hugh Fearnley-Whittingstall.

Using the best quality, locally-sourced seasonal ingredients, River Cottage’s commitment to quality, sustainably sourced ingredients and materials makes it the perfect eco-conscious eatery for Whipsnade and aligns perfectly with ZSL’s wider work.  Equally the Environmentally friendly Bio-Bubble Advance Aeration process further links with ZSL’s ecological credentials.

More Info

The Bio-Bubble biologically processes the waste from 500 covers per day along with waste from triangle wood toilet and shower facilities; the Sequenced Batch Reactor process is well known for effectively operating with feast and famine conditions typically experienced with an open air public attraction whose visitor numbers fluctuate dramatically in line with prevailing weather conditions.
We will help support Zoo staff with the day to day running of the plant, checking performance from trends of key parameters relayed back to us via the 4G broadband link;  one advantage of doing this is that actual usage can be recorded monthly, once the profile of yearly flows and loads is graphed we can look to use any spare treatment capacity within the waste water treatment plant for processing one off drop off loads from other animal waste storage points located around the site, a further attempt to reduce the carbon footprint of the Zoo by cutting the annual number of tankers leaving site with waste.  This type of waste attracts a high premium from tanker operators and therefore it follows that more of the funds can be retained for providing for the animals.



Bio-Bubble chosen to treat | Winery Waste

Posted in: Archived- Dec 14, 2017


Off The Line Vineyard is an up and coming independent producer, owners Kristina Studzinski and Ann-Marie Tynen brought their first vintage to market at the UK wine awards to be awarded a silver medal for their Hip Rose; not a bad start!

Located at Hellingley, Off the Line is a small vineyard with mostly south facing slopes in one of the sunniest areas of England, the East Sussex Weald.

More Info

Kristina and Ann-Marie have completed the building of their new winery to enable them to fulfill their dream of producing fine quality wines at Off the Line Vineyard. During the design phase of the new winery, Kristina, whose former career was a government lawyer was quick to recognise that winery waste was classed as industrial waste by the Environment Agency, and as such would require an Environmental Permit to allow biological treatment of the waste and discharge of the final effluent on site.  Being 2 km away from the water company mains network and no guarantee (even if the waste could be routed to this point) that the small village works could take slugs of very strong effluent during harvest; and having determined that in the long term on site storage of the waste for removal by tanker was going to be costly, along with not being Environmentally friendly when one considers the carbon footprint left by a tanker operating, the method of choice for dealing with the waste was full biological treatment.  The Bio-Bubble sequenced batch reactor process is well placed to deal with strong difficult wastes; as a consequence we were approached by Kristina to produce a strategy with detailed design to deal with the waste once we had gained an Environmental Permit to discharge to the water course running across the site.
It took 3 or 4 months to be granted an Environmental Permit to discharge the treated water to the water course and we were fortunate enough to have had winery waste treatment experience with 3 other sites not too far away, these provided analysis results and supporting information to demonstrate the Bio-Bubble process was a viable sustainable way to deal with the issue locally.
Bio-Bubble will remotely monitor the process with information fed back via a broadband link from the probes fitted into the reactor. This way we can make any seasonal adjustments that are needed.

Skiddaw View Holiday Park | Install a Bio-Bubble

Posted in: Archived- Sep 26, 2017

skiddaw image 3

The popular North Lakes holiday park with outstanding views across to Skiddaw has attracted many families to holiday there over the years; the location for BBC’s new comedy Home from Home as well as being featured in ITV’s travel guide; Skiddaw View Holiday Park has been owned and run by the Carr family since 1990 and has seen a focussed effort on being an environmentally friendly environment.

More Info

One of the more significant investments undertaken is the installation of a new Bio-Bubble waste water treatment plant; the Bio-Bubble will improve the quality of the water leaving the park environs to the Bulmer Beck and SSSI, before leaving the site drainage system the final effluent feeds a new attenuating pond that couples up as a water feature designed to encourage further wildlife to take up residence.  The Bio-Bubble has been designed and sized to permit a sensitive increase in park numbers over the coming years to help supply the demand for top quality accommodation and facilities in the Lake District.
As part of the new Environmental Permit which allows 35 m3/day with a quality of 12 mg/l BOD, 30 mg/l Suspended Solids and 4 mg/l Ammoniacal Nitrogen to be discharged; a comprehensive Environmental management plan has been put in place to mitigate risks to the absolute maximum numerical levels set above. To assist with the day to day monitoring of the treatment plant and the two transfer pump stations, we have a broadband link which permits remote access to the plant, email reports plant status and all alarms are monitored and stored for record, additionally the process parameters are trended on the Plant’s control room HMI, this gives engineers a quick visual aid reference for Dissolved Oxygen, pH & temperature and Mixed liquor suspended solids, furthermore one can toggle the history for comparison.  Using management information from these tools we can view build up in sludge levels, settlement speeds and the clarity of effluent at the time of discharging.
Bio-Bubble plants are ideally suited to the feast and famine nature with operation of Holiday Park facilities, the use of the Dissolved Oxygen probe to control the speed of the aeration blower along with Sleep Mode for the quieter times of year mean that only the energy required is used, unlike some systems that run 24/7 regardless.
This is the 2nd large holiday park within the Lake District National Park whose waste water is fully processed by the renowned Bio-Bubble Advanced Aeration process.



RSPCA Seal Pools | Upgrades to the Bio-Bubble systems to treat & recycle dumped water

Posted in: Archived- Jul 07, 2017

Large seal picture

The RSPCA have a history of caring for injured seals and orphaned seal pups and demands have increased for a number of years; to aid the seals recovery process both RSPCA centre’s at West Hatch near Taunton and Mallydams Wood near Hastings have reasonably large seal pools to bring on the recovery process, for the latter stages they provide relatively deep water to exercise the seals in advance of release back to the wild. It is important that the water is changed, cleaned and replaced at regular intervals, meaning that in excess of 50 m3 of additional dirty water on top of the other waste water generated from recovery pens, ponds and daily centre activity is treated. The centres rely on generous donations from animal lovers to be able to carry out their good work.

More Info

Both sites have operated Bio-Bubbles with success for a number of years with final effluent stored in a large lake at RSPCA West Hatch and a large reuse water tank at RSPCA Mallydams. The Seal pools have meant that more water was needed to be biologically processed through the Bio-Bubble, the consequence of which meant the process required far more in depth monitoring with the addition of Dissolved Oxygen and pH probes, furthermore an ultra violet disinfection system needed to be installed to replace the redundant ozone system previously used to disinfect the recycled water being returned for reuse. By recycling much of the water each centre can make significant savings on their respective potable water supply bills, meaning the monies can be directed to better use.
We remotely connect to site each day to view the control panel screen, compare trends that are logged historically and charted for quick comparison and by so doing we are able to make process adjustments right when they are needed.


Eastleigh FC | Install a Bio-Bubble to process their foul waste water

Posted in: Archived- Jun 05, 2017

Eastleigh FC image 2As part of the extensive development plans by Eastleigh Football Clubs owners Bridle Insurance, a new building to house corporate hospitality facilities for up to 300 guests has been built. The new building also houses a new club shop, offices, a  police control room, ticket office, boardroom, reception and club toilet facilities.

More Info

Silverlake stadium is located too far away from foul mains drainage so was required to biologically process all of its own waste. Advanced Aeration was commissioned to negotiate an Environmental Permit to allow a discharge of treated sewage waste into a tributary of Monk’s Brook, a feeder stream to the River Itchen.
The Bio-Bubble SBR’s bespoke design was ideally suited to provide a consistent final effluent quality balancing the twin peak flows from busy match day usage over the whole 7 day week, not only a high quality effluent with this approach but also a proportionally smaller treatment plant as it could be designed to average flows not the heights achieved on match days.
With the system connected to us via a broadband link we are best placed to provide technical expert support to Eastleigh FC staff to ensure everything is ready for the big days.
The club was without an official nickname until 2005 when a competition was run amongst the fans and “Spitfires” was chosen.
The club and supporters are proud of their nickname “The Spitfires” the infamous aeroplane designed and built locally, the club can be sure of the excellent support from local company Bio-Bubble using the latest technology of the day.



Dyrham Park | capacity had to be increased to cope with demand

Posted in: Archived- Apr 01, 2017

Dyrham Park image

Transformed from a Tudor country house into a Baroque mansion, Dyrham Park has attracted an ever increasing annual visitor number. Such is the popularity of the house and grounds, year on year visitor numbers have escalated surpassing the Bio-Bubbles 1994 design specification.

No spare land was available at the treatment works and to relocate and rebuild a whole new works would have been extremely costly. Our process engineers needed to find a solution to process more waste through the existing concrete tank assets whilst still making sure compliance to numerical consented standards was maintained for final effluent discharged to a tributary of the River Boyd catchment.

More Info

The solution was to use the improved reliable technology available to better manage the process with its huge feast and famine types of loading. The aeration capacity was increased by fitting new aeration grid matrix’s and more than doubling the amount of air available when required; this with dissolved oxygen probes in each Reactor meant that the appropriate level of treatment could be provided to the given organic loading on the day.
The installation of ‘Hach Lange’ mixed liquor Suspended Solids meters meant that our process engineers could monitor the increased sludge production and therefore maximise the process possible within the existing tank structures.
Due to the Bio-Bubble compounds position within the park; an extremely sensitive area; great care with the aesthetics and noise production was paramount to satisfy planners and not to become a bad neighbour. A big part of the solution is regular remote monitoring via a new broadband link to the system thus enabling process engineers to become part of the management of the system.
Dyrham Park is among the oldest deer parks in the country and still supports an ancient herd of circa 200 Fallow deer. The herd numbers need to be managed as part of the land management of the 270 acres, selective culling provides venison for the on-site shop. Dyrham Park recently underwent major roof replacement works along with many other improvements to further benefit the visitor experience.



London Golf Club | an ageing sewage treatment plant replaced with a Bio-Bubble system

Many wastewater treatment systems, including most available package treatment plants installed at Golf Clubs have a reputation of failing the stipulated consent and are a source of offensive or noticeable odours. Conversely, the Bio-Bubble Advanced-Aeration process has an enviable reputation of consistently achieving the highest consent limitations imposed by National and European legislation, using less energy and without any noticeable or offensive odours.

More Info

London Golf Club; renowned for hosting European Golf Tour Events, an exceptional venue was no different and along with other improvements to their course irrigation storage lakes invested in their new Bio-Bubble wastewater and sludge treatment system as well as contracting us to provide remote process monitoring support via a Broadband link. Local civil contractor Gallaher’s undertook the civil works with minimal disruption to the Golf Club’s day to day operation with a degree of professionalism to be admired.
Very high variations of effluent pollution strengths are commonly discharged from Golf Clubs throughout the day, making it difficult for continuous flow package plants such as RBC disc systems to achieve a consistent quality of treatment. The setting and clubhouse facilities at London Golf Club make it a very desirable venue to have ones wedding event which in itself can add a significant loading to the treatment works.
Typical package treatment systems generally operate under unsteady-state conditions with low or no margin for peak strength flows. In contrast, Advanced-Aeration incorporates steady-state batch treatment allowing blend-mixing and dilution of detergents and organic matter, which vastly improves the quality of the final
effluent and ensures a high quality discharge is continually achieved which in turn protects and supplements the clubs irrigation resource.
Advanced Aeration is defined as “a process that provides treatment to both effluent and sludge within a single reactor, which has the consequential benefit of producing a stable high quality effluent discharge whilst significantly reducing and stabilizing sludge waste production, with the consequential benefits of reducing both carbon emissions and overall energy usage”. This is achieved by applying:
• SBR technology
• Long process sludge age
• Low food to biomass (F/M) ratio
• Proportionate aeration to the requirements of the aerobic react phase
