Water Purification Pilot Plant

Water Purification Pilot Plant

Product Details:


Product Description


The activated sludge pilot plant consists of an oxidation reactor, of a settler and of a final chlorination tank, according to the traditional diagram of single-stage sewage treatment process. Biomass is oxidized in a reactor with agitator by the air blown by a compressor. The processed liquid is sent to the settler through an overflow. The sludge settling on settler bottom are recycled  by are circulation pump into the oxidation tank.

The water flowing out of the settler is chlorinated and conveyed to a drain. Process control,data acquisition and supervision are automatically carried out by a microprocessor controller and by a specific control and supervision software that enables the remote control of various operational parameters.


Training Program:

The process unit enables to develop and analyze the following issues:

Purification efficiency versus the following parameters:

   composition of water to be treated

   residence time

   organic load

   pH in oxidation tank

  concentration of dissolved oxygen

  Automatic PID control

  Plant supervision
