Wastewater Treatment System

 As environmental pollution escalates, water purification technologies that emphasize global environment conservation while seeking coexistence with a natural environment and a recycling-based society are desired. We offer a chemical-free environmental contaminant elimination system (patented) that uses an electro-physicochemical reaction. It contributes to conservation planning for water, space, and electric power, as well as for reduction of CO2.

Emulsified cafeteria wastewater
Use condition
  • Applicable water: Freshwater, seawater(water and sewer, ground water, industrial water, river, soft/hard water)
  • Applicable temperature: 0 to 90°C
  • Capacity: At least several tons (Developed suitable for the conditions.)
  • Power: 100V to 440V
Consumables (Maintenance
Electrode plates require replacement once in 3 months (or up to 1 year), depending on the quality of the water.
Model Processing Capability
The processing capability of the patented electrolysis wastewater treatment system MICRO WATER SYSTEM widely varies, depending on the properties of water quality and electric conductivity.
1.As industrial or livestock wastewater is directly discharged after the treatment, facilities with appropriate purification capability are required.
2.Closed circulation water systems, such as cooling towers require less energy as it takes time (3 days to half month) to improve the quality of water, and the facility size can be reduced
3.It takes long time (3 months to several years) to gradually produce the purification effect for lakes and reservoirs, and the facility size and the power consumption are kept to minimum. If there is a local inflow causing the contamination, an appropriate system is used to directly purify before it contaminates lakes.
  • Circulation water (cooling tower, etc) total capacity 20t
  • Food processing plants -wastewater treatment 100t/day
  • Paint wastewater treatment  10t/day
  • Livestock wastewater treatment  10t/day
  • Recycle of car wash water at gas stations 10t/day
  • For other uses, please contact us.
The processing capability is calculated based on the conditions, including conductivity, temperature, and processing time of the sample water.
Data of the wastewater (pH, conductivity, flow rate, temperature, storage, circulation/running water, etc) is required.
The sample water for the treatment system is tested for the quality and the system is designed appropriately for the actual conditions.

Installation Cost
Installation Cost of Wastewater, Effluent Treatment

Since the conditions of wastewater widely vary depending on actual sites, the purification test is required for each case/condition.
Take appropriate measures to keep the characteristics of water constant over time, it changes.
Purification lab test (with charge) is required for the estimation of the initial facility cost and running cost in order to provide appropriate quotations, considering factors including property of wastewater, processing amount, desire purification level, concentration, water quality items, and installation sites.
(Purification guarantee is not available unless water quality is tested.)

Cost Reduction in Wastewater Treatment

Instead of dilution, incineration, distillation & concentration, or industrial waste disposal, raw wastewater is detoxified and purified to reduce the cost and load to environment (dilution water, fuel, CO2).

Installation Cost to Cooling Tower (Total Water storage amount 20t)

We will estimate the cost appropriately for each site.

Removing red-rust through electrolysis process
Red-rust protection using the(MICRO WATER SYSTEM)
Red rust on pipes and facilities of cooling towers are removed without using chemicals. For instance, rust on the facilities caused by the Thailand flood can be easily removed using electrolyzed water processed by our electrolysis equipment.

Elapsed Time Condition
Photo (left) After 2 hours in the electrolyzed water Red rust was removed.
Photo (right) After 22 hours in the electrolyzed water Red rust was removed and black rust appears.
  • Red rust was removed, and solid and liquid were separated.
  • Rust on the parts soaked into water was removed.
  • Changed to black rust which prevents development of red-rust.

Rusted iron bars were soaked in tap water and electrolyzed water and observed.
  • Top: Before processing, Before soaking
  • Bottom: After 1 month
Processing Method Condition
Photo (left): Soaked in tap water. Red-rust was slightly removed.
Photo (center): Soaked in electrolyzed water. Red-rust was removed. Partially became black rust.
