Product Description

Pharmaceutical and bulk drug industries emanate effluent which consists of high organic contents with high COD. “SSP” has developed systems to treat such effluents, through evaporation drying technologies. Stripper column is used to remove the solvent from High COD stream. With the help of this technology, effluent concentrate is dried to a bag gable powder with 6-8% moisture content, which can be reused as a land filling / disposal.

Process:

For the purpose of treating this effluent, Evaporation and Drying methods are used. A combination of Industrial Evaporators like Falling Film Evaporator, Forced Circulation Evaporator and the Industrial Dryers like Vertical Thin Film Dryer are used. Other auxiliary techniques such as stripping of solvents, centrifuging, filtration, and incineration are also employed depending upon the characteristics of the effluent.

The effluent containing high amount of organics is heated in a reboiler and passed through a Stripper Column to strip off the maximum low boiling organic solvents and their vapors are condensed using a condenser. These condensed vapors are partially refluxed back to the stripper to enrich the column and rest of the condensate (solvent) is collected separately and can be incinerated in an incinerator for making the facility a complete Zero Pollution Plant.

The output liquid stream from the bottom of the stripper column which is now almost free of low boiling solvents enters the Multiple Effect Film Evaporator / Forced Circulation Evaporator or Combination of two for further concentration. After concentration in the Evaporator, we get a concentrated stream of effluent which can be then further concentrated or dried in different types of evaporators and dryers depending upon the actual composition of the individual stream.

The condensate water obtained from the Falling Film Evaporator is of very low COD. In case further reduction in COD is desired, then various techniques can be used like activated carbon treatment or aeration with a high pressure blower for prolonged periods.

Finally, whole of the effluent is converted into solid / sludge form so that it can be disposed using various ways like land filling. SSP has strong background in providing ETP solutions.
