Product Overview

Newterra’s DELTA Reverse Osmosis (RO) Systems provide cutting-edge water purification technology for industrial applications, effectively removing a wide range of contaminants, including dissolved salts, bacteria, and particles. These systems utilize a high-pressure pump to force water through semi-permeable membranes, capturing impurities and allowing only clean water to pass through. Designed for efficiency and reliability, the DELTA RO Systems are capable of handling varying feed water qualities, ensuring consistent output of high-purity water. Their modular design allows for easy scalability to meet increased demand, while advanced monitoring and control features ensure optimal performance and minimize maintenance requirements. Ideal for industries such as pharmaceuticals, food and beverage, and electronics manufacturing, Newterra’s DELTA RO Systems offer a sustainable solution for achieving stringent water quality standards.
