What is Wastewater and where does it come from? Wastewater, also known as sewage can be defined in the following way:
Click for Enquiry Grain Based Distilleries Grain stillage is fed into the decanter centrifuge system. The total evaporation takes place under vacuum and the vapors generated in the system are re-used to economize steam consumption. Condensate water generated from the evaporation system is clear and can be used for the process.
Condensate water generated from the evaporation system is clear and recyclable for the process. This mixed fuel is burnt in a boiler to generate steam and power.
The powder generated from spray dryer is mixed with coal and the mixture is burnt in a boiler to generate steam. It can also be marketed as potash rice fertilizer. High pressure steam is used in a turbine system to generate power.
Surplus power and steam will be available for distillery operation and other uses. After dyeing, the waste water generated is called Dye Bath water and after washing, the waste water generated is called wash water. When released in open land the effluent seeps into the groundwater which results in damage to agricultural crops, causes skin disorder and spoils ground water.
This technology saves precious water from getting polluted, thus saving the environment from ecological hazards. Stripper column is used to remove the solvent from High COD stream.
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. 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.
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.Complete characterization of ETP sludge from textile industry: focusing the reuse potentiality as organic manure Article (PDF Available) · .
Permission for collection and transportationod textile Industry ETP Sludge for research purpose to MS Shweta Goyal, Associated Professor Civil Engineering Deptt., Thapar University, Patiala. Textile sludge was incorporated in fly ash brick manufacturing and it was observed that with increase in sludge content, there is a decrease in compressive strength of bricks.
Reuse of Textile ETP Sludge from Tirupur Region as Construction Material An Experimental Investigation As per Tamil Nadu State Pollution Control Board (TNPCB) records, there are about large units engaged .
