Testimonials

What Our Clients Are Saying

I've known Lalit Vashista, MD of Diva Envitec, for the past 7 years. I approached him to discuss the filtration challenges we were facing in our plant, and we collaborated to enhance the process. We also worked together to develop new filtration designs, and Diva Enivtec made enhancements in number of other areas that helped us to substantially decrease our manufacturing costs. Lalit Vashista is very competent, does indeed have a can-do attitude, and our association is still continuing strong. He is also assisting us in emerging with some ingenuity for our wastewater treatment facility.

We were struggling with choked filters in our catalyst recovery plant. The candle filters supplied by another company were not efficient. After connecting with Diva Envitec, we have never connected with another filter supplier. We have been working with Diva Envitec for more than ten years and wish them great success in future. We are very happy with them, as they are very attentive and quickly resolve any operational issues.

Case Study

CHD-Ox -Toxic COD

Advanced oxidation treatment using catalytic hydro-oxidation removes refractory and recalcitrant COD. A multi-purpose API manufacturing plant in Telangana generates 150 KLD of wastewater. The process water and wash water flow to a neutralization tank, then to an aeration system, and finally to an MBBR. COD fluctuations due to the product mix ranged from 5000 to 45000 mg/l, destabilizing the MBBR. Consequently, the high-COD water sent to the CETP resulted in massive penalties for the company.
