Industrial Effluent Treatment System in Chennai

An industrial effluent treatment plant should normally be designed to handle the highest average daily flows experienced over the course of a year. The peak design throughput of the plant should be the average hourly flow on this peak day. A 24-h HRT in-line flow balancing tank upstream of the plant will allow accommodation of any instantaneous flows which are higher than the average.

The alternative (sizing the plant to handle instantaneous peak flow) will be likely to cost far more money, and be less controllable and flexible, due to turndown ratio restrictions and feed flow and composition variability.

The most commonly used industrial wastewater treatment techniques include adsorption, coagulation, ozonation, membrane filtration, ion exchange, chemical oxidation, and biological treatments.

Classification Of Industrial Waste And Its Treatment

Cleanup of a Massachusetts river bed contaminated with PCBs Hazardous waste, chemical waste, industrial solid waste and municipal solid waste are classifications of wastes used by governments in different countries.

Sewage treatment plants can treat some industrial wastes, i.e. those consisting of conventional pollutants such as biochemical oxygen demand (BOD).

Industrial wastes containing toxic pollutants or high concentrations of other pollutants (such as ammonia) require specialized treatment systems. (See Industrial wastewater treatment).

Industrial wastes can be classified on the basis of their characteristics:

• Waste in solid form, but some pollutants within are in liquid or fluid form, e.g. crockery industry or washing of minerals or coal
• Waste in dissolved and the pollutant is in liquid form, e.g. the dairy industry.
