Metito supplies a wide versatile range of chlorine dioxide generator systems. Our Chlorine Dioxide generator systems were designed for the preparation of carefully controlled amounts of consistently high purity chlorine dioxide at varying volumes and can be used for small, medium or large demand applications. Our generators use two precursor chemicals (sodium chlorite and hydrochloric acid) with different concentrations, dependent on model and application. Both solutions are fed from standard drums or tanks directly into the reaction chamber where the precursors are converted into chlorine dioxide.

Method of Operation

Application

Combating legionella

Food and beverage industry

Municipal drinking water and wastewater treatment

Industry (cooling towers, waste/process water etc.)

Production process

Chlorite acid (diluted)7.5 % NaCLo2 + 9 % HCI

Chlorite acid (diluted)7.5 % NaCLo2 + 9 % HCI

Chlorite acid (concentrated)24.5 % NaCLo2 + 30-33 % HCI

Capacity Overview

The two chemical precursors are simultaneously pumped (via high-quality digital metering pumps) to a holding zone within the main chlorine dioxide generator system. Here the reaction between the chemicals is controlled and designed to provide a high yield of chlorine dioxide disinfectant. In doing so, the quantity of undesirable by-products, is minimised such as chlorites that otherwise would enter the water system.

The chlorine dioxide generator systems are initiated by a water meter installed in the main water supply line. On-board system analysers check the dosing level and provide an additional control loop for system safety and integrity, whilst also providing information to both a local display and outputs to a BMS system if so desired. On-line monitoring of chlorine dioxide and its chlorite by-products is also available. With the chlorine dioxide generator systems, the measurement of chlorine dioxide, chlorite, pH value and ORP potential is incorporated in the system control, as is a data logger and screen writer.
