2 terms

membrane bioreactor technical

"a MemCor™ membrane bioreactor (MBR) system has been selected"

A membrane bioreactor is a wastewater treatment system that combines living microbes to break down contaminants with fine physical membranes that sieve out solids, producing very clean water. Think of it as a living filter plus a fine mesh that separates and recovers water in one compact unit. Investors care because it can lower long‑term treatment costs, meet strict discharge or reuse rules, and create recurring revenue or savings for industrial and municipal customers.

effluent technical

"to help provide consistent, high-quality effluent within a compact footprint"

Effluent is the liquid discharge that flows out of factories, treatment plants, or other facilities after industrial or municipal processes; think of it as the used water a business releases back into rivers, lakes or sewers. It matters to investors because its composition and management affect a company’s legal compliance, cleanup costs, permit status and public reputation—factors that can influence operating costs, fines, and long-term value.
