The Clearwater sewage treatment palnt P18 will serve up to 18 people
The Clearwater P18 uses an aeration chamber rather than a rotating disc as in the BioDisc system, so no moving internal parts.
Benefits:
-
High performance rating.
-
Can be discharged directly to a watercourse.
-
Free from mechanical or electrical components within the unit - very low maintenance and running costs.
-
Minimal visual impact on surroundings - low level cover with child safe locks.
-
Controlled ventilation.
-
Annual emptying.
Process:
Three distinct process stages take place within the single tank:
-
First, coarse solids are filtered and retained for gradual breakdown.
-
Then the resulting liquid is continuously distributed over a plastic suspended filter by an integral lift, powered by a remotely sited blower.
-
Finally, the solids are allowed to settle and, under normal domestic conditions, treated water of 20mg/l BOD, 30mg/l S.S., 20mg/l Ammonia can be achieved.
