The Apex wastewater treatment plant is of a single tank design and incorporates Primary Settlement (PST) Biological Treatment (Biozone), and Final Settlement (FST) within the same structure, allowing delivery to site as a complete unit to provide for a simple and straightforward installation. u gas cedar hill mo No other tanks are required except for larger applications ( over 300 p.e. ) where a modular system is provided or where additional treatment may be required to achieve more stringent effluent quality standards or where effluent re-use is proposed. The Apex sewage treatment plant has been designed to optimize the aesthetic qualities of the final installation by ensuring that there is minimum visual impact. The Apex process is also designed in accordance with the requirements of BS 6297.

Raw sewage enters the primary settlement tank (1) The Primary settlement tank is a two stage tank designed to maximize the removal of gross and suspended solids prior to transfer of the settled effluent to the 2 stage biozone (2) for treatment. The primary settlement tank also incorporates for a sludge storage volume (based on full load) depending on the desludge periods as identified for individual applications.

The biological treatment phase (2) of the sewage treatment plant utilizes BAF technology (biological aerated filter) which incorporates two proven principles of biological process in the form of a fixed film reactor for process stability and a suspended floc dispersed growth system for high transfer rates and operational control, to ensure a stable treatment process which is largely unaffected by shock loads. power vocabulary words Air is blown in from the blower unit (3), housed in a Kiosk which is supplied with the Apex plant. d cypha electricity The sewage treatment process incorporates a submerged plastic media on which a fixed film of friendly, sewage digesting bacteria grows. This film feeds on the sewage liquor passed from the settlement tank and is provided with oxygen by means of a small blower unit which aerates the media through HDPE membrane diffusers to provide fine bubble aeration. table d gaskets The action of the fine bubble aeration is carefully controlled to provide optimum oxygen transfer rates.It also gives a scouring action to slough off excess biomass to keep the thickness of the fixed biological film at optimum levels, ensuring maximum sewage treatment process efficiency. The fact that the media remains submerged allows for an element of suspended floc dispersed growth, which basically means that there will be bacteria which is unfixed to the media but achieving sewage treatment as a biological ‘soup’.

The biozone incorporates a two stage process as standard that allows for constant mixing of incoming settled effluent to provide optimum treatment stability and to avoid any short-circuiting. gas in oil lawn mower The use of a two stage biozone in the sewage treatment plant ensures a high degree of process efficiency to not only reduce B.O.D. levels to that required, but will also achieve reductions in ammoniacal nitrogen way in excess of standard requirements

The final settlement tank is designed in accordance with the requirements of BS 6297 to ensure relevant surface areas and rise rates are achieved to provide maximum settlement of any suspended solids prior to discharge. The Apex sewage system also incorporates continuous and automatically timed humus sludge return systems (4) to return humus sludge from the final settlement tank, back to the primary settlement tank. This is the special function that ‘feeds’ the bacteria whilst you are away on holiday, a feature that is missing on most modern sewage treatment plants, but remains on the Apex. 4 gas planets Additionally this sewage system also provides for continuous recycling of treated effluent back to the P.S.T. to not only provide dilution of incoming wastewater, but to also ensure continuous flow during periods of low or no flow, thereby keeping the biomass in prime condition. It also enables denitrification, further reducing the ammonia in the final effluent.
