| Introduction :: |
| The New Generation PSTP is the most compact "all in one" system available. The civil works are minimal, consisting of a flat concrete support slab the plan area of the unit constructed is 1.4 mts. below the invert of the incoming pipe. The units are fully covered preventing noise and fly nuisance. It is a modular unit that lends itself to future expansion or relocation. |

| Product Description :: |
| Tankage :: |
NG PSTP is a single tank system and can be supplied in modules. The tank is made of MS with both internal & external FRP lining and can be free standing. The tank and internal components are accessed by a series of lockable covers capable of being lifted by one person.
|
| Mechanical :: |
The shaft supporting the media is manufactured from EN 8 steel and has a variable diameter. It is driven through a helical gear type reduction gearbox with an output speed of 6 RPM.
|
| Electrical :: |
A single control box is mounted in the motor / gearbox compartment and accessible from the surface. It contains all the electrical controls and is to IP 55 standards.
|
| Working Principle :: |
| Primary settlement :: |
Sewage initially enters the primary settlement tank. The tank incorporates lamella parallel plates which aid in reducing the suspended solids by 70% and the BOD by 25%. This zone is relatively maintenance free and contains no moving mechanical or electrical devices.
|
| Aerobic Treatment :: |
The effluent then enters the aerator bio-zone, which is a combined fixed film reactor and active aeration system mounted on a horizontal shaft. The aerator provides a solid surface area for micro-organisms to attach themselves; these then feed on the organic matter present in the effluent. The rotation of the drum creates an aeration of the liquid. The bio-zone is self cleansing and does not require extraneous pumping or sludge return.
|
| Final Settlement :: |
The treated effluent then moves to the settlement area. This area contains a lamella parallel plate assembly for settling finer particles. The submersible pump removes sludge to the sludge storage compartment on a regular basis.
