History and Background

Mechacera system was developed by a SEISUI in 1983 through joint research with Tohoku University - a Japanese National university.

Key technology of this system is Super Oxide Ion Generation Method. (Patent filed) 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 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 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.

3 Factors for Mechacera Water

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)
