Ventilair Engineers Private Limited

"VENTILAIR ENGINEERS" is a leading manufacturer supplier company of effluent treatment for ELCTROPLANTING in india. we have already installed 700 above waste water treatment plants . VENTILAIR ENGINEERS have also installed EFFLUENT TREATMENT PLANT for ELCTROPLATING COMPANY.
This unit is designed and installed for M/S. KEWAL MOTORS by VENTILAIR ENGINEERS.
We offer electroplating plants which are one of our most popular and reliable plants, the electroplating plants are available with in the operating options of automatic, semi-automatic and manual. we provide our best engineers who are experts in their respective domains.

Typical plating includes brass, nickel, cadmium, zinc, silver, copper, and gold. Electroplating wastewater is typically from washing, rinsing and batch dumps and is at a low pH of ~3-5 and contains soluble forms of the various metals. In order to remove soluble metals from the wastewater it must first be made insoluble. The insoluble metal is then coagulated, flocculated and clarified by sedimentation.

The typical method to reduce and remove soluble electroplating metals from wastewater is as follows:

1.     pH is raised from ~3 to 8.5 with the pH controller using caustic while adding a coagulant such as ferric chloride. Testing of the wastewater may confirm that a coagulant is not needed. A “pin floc” is developed indicating the metal is insoluble. Some applications have plating enhancing chemicals present, emulsifiers and such that may require more sophisticated high performance coagulants to break the bonds and allow the metal to precipitate.
2.  The wastewater with it’s precipitated pin floc is introduced to the flash mix zone where a polymer flocculent is added. This stage maximizes flocculent dispersion throughout the coagulated wastewater.
3.  The wastewater is now introduced to the slow mix zone to agglomerate the pin floc into larger rapid settling particles.
4.   The flocculated wastewater is introduced into the clarifier where the settling particles land on the inclined plates and are directed downward and into the sludge chamber. The clarified treated water then exits the top of the clarifier and flows downstream to sewer or further treatment if necessary.
5.   The resulting clarifier waste sludge is periodically removed from the clarifier at a slow rate and sent to the sludge holding tank where it further thickens and accumulates a batch for disposal or processing in a filter press.
6.   The thickened clarifier sludge is allowed to accumulate sufficiently to provide a full batch for the Filter Press. The filter press is pumped full of the sludge until it is full. The filter press is then emptied of the “cake” which is a semi solid of approximately 20-35 % solids. Sludge cake is high in phosphate and should be disposed of according to environmental regulations.

Ventilair Engineers has successfully installed ETPs for numerous tanneries, both in India and internationally. Our plants have consistently helped clients meet environmental discharge norms while optimizing operational costs and enabling reuse of treated water in non-potable processes.

ETP (Effluent treatment plants) from VENTILAIR ENGINEERS PVT.LTD (VEPL) are designed to treat industrial effluent, which consists of wastewater, sludge or sewage. These effluent treatment plants are tailored to remove harmful pathogens, clear hazardous chemicals, detergents and toxins, and separate and
extract valuable substances from effluent.
Industrial undertakings those wish and are needed to install an ETP have to consider several factors. They include information and parameters (quality and quantity) of their wastewater that are discharged from their factory. This information can be derived by getting a sample of the effluent water tested and analyzed at an authorized laboratory.

Some of the factors to be considered while choosing an ETP are as follows:

Knowledge of law of the land (national and international rules and regulations) in regards to water and wastewater treatment that you have to comply with.

What quantity of effluent is produced in your entity on daily basis?

1 The chemical contents and their concentration in the effluent.  For instance, 30m3/hour with COD of 500ppm, and pH of 11.5.

What is your budget for installing and running the ETP?

Can you spend on its maintenance once it is installed?

Do you have enough and suitable land area for the desired construction and installation?

Choosing the right vendor is one of the critical factors to consider. An expert in the filed who provides excellent aftersales service should be considered.

As there are many types to consider, choose the ETP that best suits your company requirements.

Better recruitment and training to the personnel responsible for operation and maintenance of the plant.

Today, indicating economic self-sufficiency and employment scopes, the Bikaner Industries continue to grow beyond leaps and bounds. The fibers used in the woolen/carpet industry may be broadly classified into four groups: cotton, wool, regenerated and synthetics. The characteristic of the waste from the mill depends on the type of fiber and chemicals, dying used as different type of fibers and chemical go through being sent out of the mill. The pollutants are the waste water includes the natural impurities in the fibers used, and the processing chemicals The entire liquid waste from the Carpet and Wool Dying industry comes from the following operation of slashing (or sizing), scouring and desizing, bleaching, mercerizing, dying, and finishing. Enzymes are usually used in India to hydrolyze the starch; acids may also be used for this purpose. Caustic soda, soda ash, detergents etc re used in scouring in Kier boilers. Replacement of soap used in scouring by low BOD detergents may reduce BOD load by 35%. About 50% of the total pollution load of the mill is contributed by this section. Bleaching operations use oxidizing chemicals like peroxides and hypochlorite to remove natural coloring materials. This section contributes about 10% of the total pollution load. Mercerizing consists of passing the cloth/wool through 20% caustic soda solution. The process improves the strength, elasticity, luster and dye affinity. Waste from this section is recycled after sodium hydroxide recovery. Negligible waste which may come out of this section contributes little BOD but a high degree of alkalinity. Dying may be done in various ways, using different types of dyes and auxiliary chemicals. Classes of dye used include vat dyes, developing dyes, naphthol dyes, sulfur dyes, basic dyes, direct dyes etc. Some years ago, Govt. of india had handed over its responsibilities of implementation and monitoring of industrial effluent standards to the central pollution control board and related state pollution control board, whose prime aim is to promote the industries, not to penalize them for the cause of environmental pollution. However, this implementation and monitoring of standards given to cpcb has no longer effectives. In Bikaner, all most all water resources have turned to ecologically dead due to indiscriminate discharge of sewerage and other industrial effluents thought its stretch passing across the city. Moreover, the large fraction of number of industrial set up has been set up in Bikaner city. Among them, more than 40 percent of the industries are of water polluting nature and hence the overall industrial pollution in the Bikaner is even very high and more serious. . Most of these establishments are in the near by or attached public residential area.
