Electro-Chemical Technologies to Test Aquachlor Technology in Municipal Water System.

Business Editors/Technology Writers

LAS VEGAS--(BUSINESS WIRE)--Dec. 23, 2002

Electro-Chemical Technologies Ltd. (Pink Sheets:ELCH) (www.ectltd.net) announced today that it will install a prototype Aquachlor-100 potable water disinfection system in a small North American municipality in January.

The system will be tested for approximately four weeks with the assistance of a technical expert from ELCH's strategic partner, the Moscow-based Russian Scientific and Research Institute for Medical Engineering.

The Russian expert specializes in the design of Aquachlor devices, the on-site chlorine generators that are the primary components of the Aquachlor system. This program is intended to test the effectiveness of the Aquachlor versus competing system's in two key areas: efficacy and cost-effectiveness.

Aquachlor technology has been in continuous use in municipal water systems in the Russian Federation since 1998. ELCH's Aquachlor-100 is capable of producing 100 grams per hour of free available chlorine (FAC). It is the smallest of a family of devices belonging to a new generation of compact, economical and environmentally friendly electro-chemical activation (ECA) systems for the on-site generation of gaseous chlorine that are capable of serving small and medium-sized municipalities. Aquachlor systems offer the following advantages:

-- On-site generation of chlorine gas using brine and electricity only and direct injection into the water being treated;

-- Does not require the use, storage or transportation of hazardous chemicals;

-- Does not require special training in the use of hazardous materials due to low FAC content in the generated stream of oxidants;

-- Close to the highest possible salt conversion rate;

-- Does not increase TDS (Total Dissolved Solids) level of treated water;

-- Low power consumption;

-- Low maintenance;

-- Easy to operate;

-- Superior disinfection performance;

-- Minimal disinfection by-products (DBP) formation at high biocidal rate -- 30%-50% reduction in trihalomethane (THM) formation compared to traditional chlorination methods.

-- Variable capacity due to modular design.

According to Jack Brebbia, President of Electro-Chemical Technologies: "The prototype installation is expected to demonstrate that the Aquachlor is a far more environmentally friendly and cost effective system than the competing products that are available in North America today. We believe that the introduction of the Aquachlor is the first step in positioning ELCH to become a market leader in the areas of municipal and wastewater systems for small and medium-sized municipalities."

Electro-Chemical Technologies, Ltd., is a Nevada corporation dedicated to developing and commercializing its patented technology primarily in the U.S. market, concentrating in the areas of municipal water and wastewater treatment systems; military and civil biological and chemical decontamination; food safety; and high-level disinfection in the medical and healthcare sectors.
