Waste Water Treatment
Industrial produce of Waste water or commonly termed as effluent have different characteristics based upon the solid content, soluble content and oxygen demands as per the industrial segment.
Due to various norms the water has to be treated by means of different methods separating pure water from rest of the content.
Chem process has a unique range of processes to take care of your effluent starting from
- Forced Circulation Evaporation plant
- Rising Film Evaporation plant
- Falling Film evaporation plant
- Plate type Evaporation plant
- Crystallizing units
- Adiabatic type crystallizers
- Oslo Type Crystallizers
- Draft and Baffle Tube Type Crystallizers
- Induced circulation-type Crystallizers
- Natural circulation evaporation plant
- Combination of the above systems
- Stripping units
- Agitated thin film dryer
- Drum Dryer
- Paddle Dryer
- Screw Conveyor Dryer
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
