Desalination System
"Engineering Excellence Guaranteed. Committed to provide world class products"
Overview
Large quantities of industrial waste waters/effluents with strong contaminations of different compositions are generated in the production and processes of almost all industrial sectors. These waste waters have to be treated before they can be discharged into the specified permissible system. Hence an efficient and environmentally friendly waste water treatment is required.
Chem Process partners with you to provide the best solutions for treatment of industrial waste waters. As one of the leading designers and manufacturers of thermal and mechanical process equipment with core competence in evaporation, crystallization, vacuum and heat transfer, Chem Process offers custom made plants with additional upstream or downstream process steps. Suitable combinations of processes in our plants achieve optimum results for the recovery of water and valuable products.

Research & Development
Chem Process has an in-house research and development centre with the required laboratory equipment, where waste waters are tested and treated for their behavior and based on the results, appropriate plant components, pre and after treatment are selected and designed. Mobile pilot plants are also available, which if required are sent to our customer’s location for carrying out tests.

Treatment of Waste Waters from Chemical Productions/Processes
In the production processes of various pharmaceuticals, bulk drugs, agrochemicals, pesticides, dyes, dyes intermediates, textile, power, water treatment, galvanizing and various other chemical industries; waste waters produce essentially consist of several organic components, salts and water. Treating these waste waters is very difficult as they are toxic and cannot be treated in a bio-reactor due to high salt contents and hence also hinder dumping. The only method of disposal is to remove all the water, solvents and produce solids for reuse/disposal. In case of high COD contents having high boilers, the only option of disposal is by incineration. In such cases too, concentration prior to incineration is recommended. Both these tasks of concentration and separation can be optimally achieved with thermal treatments, technologies consisting of evaporation and crystallization.
Process Description :
The water portion is concentrated in the evaporation plant. The salt is separated by crystallization which may be by way of evaporative crystallization or a separate crystallizer arranged downstream of the evaporation plant. Then if required the volatiles are removed from the vapor condensate in a rectification column/stripping. Thus only the concentrated organic matter which is very small in quantity has to be incinerated.
Treatment of Waste Waters from Biotechnological Processes
Production / Processes :
In biotechnological production/processes, a biological treatment is not efficient, or is too complex because the continuation levels of organic substances and salts are very high. However these contents may be suitable for the production of fertilizers and animal feeds/fodder. Hence the best treatment solution for these waste waters is to first concentrate them in an evaporation plant and then dry the residual matters for further use in the production of fertilizers/animal feeds/fodder.
Biotechnological Processes :
- Drinking Alcohol Production
- Ethanol Production
- Glutamic Acid Production
- Lysine Production
- Yeast Production
