Electrolytic Wastewater Treatment System

MICRO WATER SYSTEM®

As environmental pollution escalates, water purification technologies that emphasize global
environment conservation while seeking coexistence with a natural environment and arecycling-based society are desired. We offer a chemical-free environmental contaminantelimination system (patented) that uses an electro-physicochemical reaction. It contributes toconservation planning for water, space, and electric power, as well as for reduction of CO 2.
Our system has been adopted in the “Kasumigaura water purification project” (a project fordeveloping technologies to purify eutrophicated lakes by the Ministry of Education, Culture,Sports, Science, and Technology), “Development of a purification system for hard-to-processwastewater such as wastewater from dairy parlors” (by the Ministry of Economy, Trade, andIndustry), and the “Purification project for dam lakes” (by the Ministry of Land, Infrastructure,Transport, and Tourism), receiving recognition for its efficient water purification performance.

What Are the Costs of Treating Industrial Water and Sewage?

If water intake is 20t/D and the same amount is discharged, the total costs, including the fees
for industrial water and treatment of sewage, will accumulate to huge amounts over a period offive years as shown in the charts below.
For example, if wastewater from the factory is purified and 85% of it is reused, conservation ofwater leads to a substantial savings in costs.
Investing in a wastewater purification system and conserving water can reducemuch more cost than diluting and discharging wastewater from the factory.
