Cooling Tower Water Treatment, Water Treatment for Cooling Towers | Industries | MIOX

Commercial & Institutional Water Disinfection/ Cooling Tower Water Treatment


MIOX is a cutting-edge technology company that delivers smarter cooling tower water treatment solutions to improve cooling tower efficiency and safety, all at a lower cost than conventional biocide treatment methods. MIOX’s patented Mixed Oxidant Solution and sodium hypochlorite on-site generators are available in sizes to fit every application. Our on-demand chemistries have a proven track record for legionella prevention, biofilm removal, and inactivation of other performance-inhibiting waterborne organisms.

Technology Overview

MIOX systems use a proprietary electrolytic process, electrolyzing a brine solution (either based on salt or delivered brine) and producing primarily two different chemistries:

Mixed Oxident Solution
Sodium Hypochlorite

The Mixed Oxidant Solution is proven to be more effective compared to straight sodium hypochlorite especially in controlling biofilm due to the trace amounts of Hydrogen Peroxide that resides in the solution along with hypochlorite up to 24 to 48 hours at high pHs.

How it Works

MIOX on-demand chemistries are fed directly into the tower sump or injected into the circulation loop from a buffer tank. The system can be controlled by the existing Hypochlorite chemical control system on site, either ORP or chlorine analyzer.

A Case Study

The cooling system had a constant problem with algae and biofilm growth in the cooling tower basin. The facility wanted to improve safety and control the algae and biofilm, without increasing the use of existing biocides, which already contributed between 50 to 70% of total treatment costs.
