Eleca®
Electrolysis technology (Eleca) in wastewater treatment
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.
Eleca equipment flow（Smaller space than microbiological treatment）
Specification of Eleca
Specification
| Equipment size | H ：2.6m W：6m D：3m |
| Ammonia nitrogen treatment capacity | Approx.100m3/day. The condition to reduce ammonia nitrogen from 200mg/L to 10mg/L or below |

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 electrodesthat 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.
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 CODMn adsorbed on activated carbon per gram
Equilibrium density ： CODMn 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.
Case5 Odor control of shells
Problem：Odor problems with shells collected at ports, etc.
Case6 Jellyfish Odour control and decomposing
Problem：Decomposing of collected jellyfish at seawater intake for cooling.
