Abstract (en)
[origin: WO0147615A1] A water treatment apparatus utilizes membrane separation technology to separate clean product water from a contaminated water source. The water treatment apparatus comprises an external pressurized raw water source, a raw water inlet, a raw water filter, a main drive pump, a valve arrangement, water treatment means, an inverse flush system having a product accumulator tank and an inverse flow pump, a pair of separation chambers, a recirculation pump set, treated output water storage means, an external fast flush water supply, and a waste water discharge. Ducting connects these components and communicates water therebetween. A cylindrical housing formed of high density polyethylene surrounds the pump and includes a baffle plate and centering ring assembly for supporting the pump. An end pug is located in place by pins passing though holes in the plug and in the wall of the housing. A further housing of similar construction receives the membrane element and provides ports and seal arrangements which act to balance pressure across the membrane.
