Industrial wastewater and waste-to-energy plants, engineered with agentic systems built for the job.
01 · Portfolio
The same plant seen three ways: the company that owns it, the company that built it, and the firm that engineers it. The operating contribution to each is the same: deep technical expertise, delivered as agentic infrastructure.
01 Own & operate The digester bank from the air: four membrane domes, two open digestate tanks alongside, and the covered pressmud pad beyond · Circle CBG
02 Build 2022, during construction. Vertical reinforcing bars rise around the rim of a concrete tank floor, with workers at the base · Circle CBG
03 Engineer
Founder · Principal Engineer Process engineering for industrial wastewater and waste-to-value plants. ContributionBuilds PuranOS, the agentic infrastructure that carries that expertise into the other two. puranwater.com Feed-gas compressor. Boosts cleaned biogas to membrane feed pressure · Circle CBG
02 · Plants
Twenty years of industrial water and waste-to-energy work, from gas-plant effluent in Russia to rice-wine stillage in Taiwan and sugar-mill pressmud in India: different feedstocks, different work cultures. Scroll to walk the route; it ends at Meerut, the portfolio’s own plant.
