Effect of Eleca

Electrolysis technology

・Treats ammoniac nitrogen, COD and BOD in wastewater.
・Contributes to improving the adsorption efficiency and extending the life of activated carbon by decomposing and reducing the molecular weight of water-soluble organic matter.
・Decolorization (Decoloration) of wastewater.
・Deodorising wastewater.

Features of Eleca

Stabilization

The process is stable in all seasons and weather conditions.

Simple operation management

Operation is only ON/OFF.
Reduces the burden on facility managers.

Small space

Layout flexibility for any installation location.
Supports replacement of existing equipment and facility expansion.

No sludge

Electrolysis uses chemical reactions to break down and treat target components.
No sludge or other waste is generated,
making the equipment both operational and environmentally friendly.

Highly durable electrodes produce active oxygen

Over the years we have developed electrodes
that efficiently generates reactive oxygen species
and are excellent in corrosion resistance.
The electrode replacement life is low, contributing to lower operating costs.

Eleca case study

Kind of wastewater：controlled landfill leachate.
Feature ：containing NH4-N and component of COD and BOD, etc.

About NH₄-N decomposition reactions

Decomposition of BOD and COD components

Effects of decomposition of COD and BOD components

Increased activated carbon adsorption efficiency and life extention

Equilibrium adsorption： Amount of COD_Mn adsorbed on activated carbon per gram
Equilibrium density ： COD_Mn content after reaction of samples with activated carbon
The higher the equilibrium adsorption at the same equilibrium concentration, the more effectively the activated carbon pores are used.

Case study

case 1：Oil-containing wastewater

Wastewater： Produced water from oil field.
Problem ： Acetic acid and propionic acid cannot be treated with flocculants.

Case2： Chemical wastewater

Problem：1,4-dioxane is persistent substances and have difficulty in treatment.

Case3 Chemical wastewater

Problem：Although various treatment techniques were taken, the color does not fade.

Case 4　About Dioxin

Dioxins are persistent substances that are hardly degraded in the natural environment.
The ratios of incineration and combustion get higher as the effluent sources of dioxin.
