Protecting the Environment - The WPL Diamond treats the sewage using no chemicals and to a high standard, so that the effluent can be safely discharged
A.The wastewater flows into the main tank and enters directly into the bio-chamber (B) through this inlet pipe (A).
B. This is where the biological process begins. the bio-chamber (B) is an aerated zone where the solids circulate and are thereby biologically treated. Part of the solids settle in to area (C) only to be re-circulated via the draft tube (D) and re-treated.
C. In this area, the settled solids from the bio-chamber (B) and the clarifier (E) are drawn up through the draft tube again and released into the bio-chamber for re-treatment.
D. The draft tube enables the solids to be drawn back up into central aeration chamber and re-circulated through the treatment process.
E. This is the clarifier. There is no aeration in this area. The fluid flows upwards through the clarifier as it is being displaced when more wastewater enters the tank. The remaining solids settle out again into area (C) and are re-circulated via the draft tube (D) into the bio-chamber(B).
F. The clarified liquid then percolates through the holes in the bottom of scum board assembly and flows over the weir.
G. The clarified fluid flows out over the weir, into the outlet pipe and is then discharged
The Diamond treats wastewater to a 95th percentile standard of:
• 20mg/l Biological Oxygen Demand (BOD)
• 30mg/l Suspended Solids (SS)
• 20mg/l Ammoniacal Nitrogen (AMM-N)
Air Blower
The Diamond’s air blower is supplied with a failure alarm and a kiosk to protect it from the weather.
Your plant comes complete with 10 metres of airline to connect the blower and the tank. The Diamond can accommodate longer airlines of up to 30 metres from the blower; please speak to a member of our sales team for more information.
