Double Pass Reverse Osmosis (RO) System

Overview

At Aqutech Plus Private Limited, we specialize in cutting-edge water treatment solutions. Our Double Pass Reverse Osmosis System is designed to meet the highest standards of purity, reliability, and efficiency. This advanced system ensures ultra-low conductivity and reduced TOC levels, ideal for industries where water quality is critical.

The second pass RO unit treats the permeate of the first pass to ensure consistently ultra-pure water, especially for pharmaceutical, power, electronics, and high-end manAPUFacturing applications.
