Mechacera System Profile

History and Background

Our main business, “MECHACERA System”, was developed in 1983 through joint research between Tohoku University and Seisui Corporation.

The core technology of this system is the Superoxide Ion generation method, which is used for water purification treatment of waste oil, etc., and for deodorization, water purification, and sludge reduction of human waste and miscellaneous domestic wastewater in agricultural communities and sewage systems. The water purification quality is remarkably stable, low-cost, and does not require any modification of existing facilities. In the more than 30 years since its release, MECHACERA equipment has been used in many production plants of major Japanese companies, including local governments (Agricultural Community Wastewater Treatment Facilities), and in many other countries.　

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 lightenergy (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/Advanced Ceramics) 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 rays.

This is a "Catalytic Reaction" obtained by bringing the above three elements into continuous contact. As a result, "Mechacera Water" is generated, and when the Mechacera Water is passed through waste water (circulating water, etc.), it has various effects such as scale removal, oxidative decomposition, deodorization, and sterilization.

Chemical Reaction is as follows;

​　NaClO (Sodium Hypochlorite) + H₂O (Water) → NaOH (Sodium Hydroxide) + HClO (Hypochlorous Acid)

​　HClO (Hypochlorous Acid) → HCl (Hydrochloric Acid) + [O] (Nascent Oxygen)

​​■ [O] is nascent oxygen that exhibits a strong oxidizing effect

​■ pH adjustment (H⁺ reduction reaction)
