Description

AFW012 Aerobic Water Purification Pilot Plant Didactic Equipment Water Treatment Trainer

INTRODUCTION

The activated sludge pilot plant consists of an oxidation reactor

and of a settler according to the traditional diagram of singlestage 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 overfl ow. The sludges settling at settler bottom are recycled by a recycle pump into the oxidation tank.

TRAINING PROGRAM:The process unit enables to develop and analyze the following

issues:

Purifi cation effi ciency versus the following parameters:- composition of water under to be treated- residence time- organic load- pH in oxidation tank- concentration of dissolved oxygen
