Suggestions for further research,he pH range around 7.0. In some instances, however, for attaining the desired degree of pollutant removal (e.g. removal of heavy metals, ammonia stripping, lime-soda water softening) it is necessary to change the pH of the water or sewage to be treated. The pH of the effluent discharged is often sub

Suggestions for further research,ing carried out by sedimentation. The reaction step (coagulation/precipitation) is obviously of fundamental importance to the total treatment result, but the separation steps (flocculation and floc separation) have far greater importance from an economic point of view, since separation normally take

This paper reviews some aspects of proper SCD usage, and then provides an improved theoretical description with experimental validation, and a
