Mechacera System - Wastewater Purification System
■ History and Background
Mechacera system was developed in 1983 through joint research with Tohoku University - a Japanese National university.
Key technology of this system is Super Oxide Ion Generation Method (Patent: 3537085). Its main products are for Wastewater purification, Treatment of waste oil, Deodorization of human waste and household wastewater, reduction of sludge in small town
/villages and sewers. Actually, Water purification quality is surprisingly stable with low running cost. When installing Mechacera
device, there is no need to change existing equipment, besides reliable and robust ceramic balls can be used semi-permanently. For
more than 30 years since its launch, Mechacera system has been adopted by major companies and Japanese Local government in
Japan as well as overseas customers.
■ Key principles
Active oxygen is generated from Photooxidation catalysts such as titanium oxide, which is currently attracting attention, and various functions are recognized. However, Titanium oxide does not generate a strong oxidant, active oxygen, unless it uses light
energy (ultraviolet rays). Therefore, these catalysts require ultraviolet light as energy, do not work at all in the dark or in water,
and are ineffective.
In the Mechacera system, adding a small amount of Chlorine (Sodium Hypochlorite) to the special ceramic (catalyst) generates
Active Oxygen (Hydroxy Radicals) even in water, and the energy of Chlorine acts on the ceramic. It generates Active Oxygen
(Hydroxy Radicals) even in water or in places where light does not reach, just like when Titanium Oxide is exposed to Ultraviolet
These patents and core technologies are simpler in principle than conventional technologies, and are characterized by their small size, significantly lower construction costs, easy maintenance, and even extremely long life. In recent years, environmental
issues have become an important theme of society and are well received from various fields, such as Sewerage, Agricultural
settlement drainage business, and Food factories.
■ Applicable facilities and effect by Mechacera system

Mechacera-System can be used for a quite longer time (more than 10 years at least) without replace of the ceramic balls by
maintenance properly (wash and clean the ceramics every year). Also, Operational chemicals (i.e. chlorine) can be greatly
reduced which should be friendly to environment.
