PURIFYING LONDONS AIR AND WATER BY BIORECYCLE BIO-FILTRATION
The well tried BioRecycle biomass recycling sewage treatment process where sewage and biomass is continuously recycled over a bio filter, consisting of high surface area media in an enclosed tank with a soil cover has been in wide use in the UK, Ireland and other parts of Europe in packaged plants reducing greenhouse gas emissions from sewage since 1983. Bio-filtration is also an attractive technique for the elimination of low levels of fine particles and nitrogen oxides and other air pollutants arising from petrol or diesel powered vehicles and heating fuel emissions.
PROTECTING THE COUNTRY’S PREMIER FLY FISHING RIVER FOR 27 YEARS
The BioRecycle sewage treatment process has been ensuring the River Avon at Woodford near Salisbury retains its reputation as the country’s premier chalk stream salmon fishery since 1990.
A biomass recycling sewage treatment plant according to Geoff Jensen's 1983 Patent has been purifying the sewage from the Bridge Inn and some neighbouring houses discharging into the River Avon where it passes through the Woodford Valley since 1990.
The plant remains as it was built 27 years ago and operates unattended except for two service visits a year.
Latest sampled results from the treated sewage effluent from the Bridge Inn show the plant produced an ammonia level at 0.09 parts per million which is 1% of the permitted level and shows both the long term reliability of the process and why it ensures this part of the Hampshire Avon continues to be considered to be one of the finest chalk stream trout (Salmo trutta) fisheries in the country according to the Wild Trout Trust.
The BioRecycle plant modules for the proposed London Green Route will be of similar plan dimensions but slightly deeper to accommodate extra storm overflow capacity as required and installed as a linear series.

GEOFF JENSEN Inventor and Environmental Engineer
A graduate Civil Engineer with long experience of working in drainage and sewage treatment and has been granted from 1983 UK, European, US and many international patents for 3 different variations of his sewage treatment process.
Inventor of the odour free below ground sewage treatment by the Biomass recycling process, cutting greenhouse gasses for 30 years. Now manufactured by The Klargester Biotec. Certified to British and European Standard BS EN-12566.
The Biotec is described by Klargester as one of the products that pioneered packaged sewage treatment plant technology and remains the UK and Ireland's most popular packaged treatment plant.
Geoff improved the fixed film sewage treatment process to reduce ammonia and sludge production to such an extent fish could live in the final settlement tank.
Geoff has also been granted patents for glass fibre reinforced composites and produced engineering design in GRP composite to obtain European Norm12566 for manufacturer of packaged sewage treatment plant. He has sat on BS and ISO committees on reinforced plastic pipes.
In his early career Geoff worked on the River Thames from Maidenhead to Staines on bank erosion protection and on the tidal Thames from Teddington to Chelsea on bank raising, prior to the building of the Thames Barrier.
He has been working on sewage treatment for sea outfalls and combined storm overflows since 1987 supplying information to the Commons Environment Committee chaired by Sir Hugh Rossi in 1989.
