The Conder ASP package sewage treatment plant continues to boast high levels of performance.  Having undergone 40 weeks of independent European testing, the ASP demonstrated an efficiency rating equivalent to a performance of 8mg/l BOD, 12 mg/I SS and 7.7 mg/I ammonia, total phosphorus 3.3 mg/l and total nitrogen 26mg/l.

This represents a highly effective level of sewage treatment, good enough to discharge into rivers and streams (subject to relevant exemption/consent or license).  The Conder ASP continues to be recognised by planning departments and environmental authorities nationwide as the preferred solution for domestic homes looking for an off-mains solution.

Process and plant description

The ASP treatment plant comprises a single tank.  Within the tank there is an inner central bio-zone chamber and an outer settlement zone. 

The plant accepts and treats the incoming sewage, using the extended aeration principle, in the central bio-zone chamber.  A simple coarse bubble diffuser, housed in a draft tube, introduces the air that provides the oxygen to the bacteria, which then treats the sewage. 

The bio-zone retains the mixture of sewage and bacteria until the level of treatment has been achieved.

The treated effluent then enters the settlement zone where settlement takes place.  The settled solids are drawn back towards the draft tube, with the diffuser in it, and are then returned via the airlift principle to the bio-zone for further treatment. 

The treated (final) effluent subsequently leaves the plant over a weir, at the outlet level, that extends around the circumference of the tank.  The movement of fluid through the whole system is by gravity displacement. 

There are no moving parts in the treatment plant.
