PROVIDING ULTRAPURE WATER FOR THE MICROELECTRONICS & SEMICONDUCTOR INDUSTRY

Biological wastewater treatment is often used as a secondary treatment process to remove material remaining after primary treatment. Biological treatments rely on bacteria, nematodes, or other small organisms to break down organic waste using normal cellular processes.

The RO process removes over 99% of the dissolved solids from the feedwater, leaving approximately1%, which is unacceptable for many applications

Industrial plants in most sectors create wastewater with their processes. This wastewater can be discharged, based on local regulations and permit requirements, or reused within their process.

Reverse Osmosis (RO) uses the principle of osmosis to remove salt and other impurities, by transferring water through a series of semi-permeable membranes.

Zeroliquid discharge (ZLD) is a water treatment process in which all wastewater is purified and recycled; therefore, leaving zero discharge at the end of the treatment cycle. Zero liquid discharge is an advanced wastewater treatment method that includes ultrafiltration, reverse osmosis, evaporation/crystallization, and fractional electrodeionization.
