Industrial Wastewater Treatment System

As environmental pollution becomes more serious, water purification technology that emphasizes global environmental conservation, coexistence with the natural environment, and a recycling-oriented society is desired.

We propose an environmental pollutant removal system (patented) that does not use chemicals. The system is designed to save water, space, and power using the direct purification method.

  • Applicable capacity: Develop equipment according to conditions
  • Power source: 100V to 440V
Consumables (maintenance)
  • Consumable electrode plates need to be replaced every 3 months to 1 year for active electrodes, depending on water quality.
  • For inert electrodes, electrodes do not need to be replaced.
Model Capacity
The treatment capacity of the MICRO WATER SYSTEM® electrolysis wastewater treatment system (patented) is custom-designed for each water quality condition.
  1. Wastewater from factories, dairy farms, etc. is diverse and requires immediate water purification treatment after intake of wastewater, so equipment that meets the required purification capacity is necessary according to each site's needs and conditions.
  2. For cooling towers and other closed circulating water systems, it takes more time (3 days to half a month) to improve water quality, so the minimum energy-saving equipment is required.
  3. Lakes and dams (3 months to 1, 2, or 5 years) are gradually purified over a long period of time and treated with equipment appropriate for the local inflow that causes pollution with little energy in a short period of time to directly purify the water before it spreads to the lake and causes pollution.
  • Circulation system treated water (cooling tower, etc.) total storage capacity 10m3 ~.
  • Food factory wastewater treatment 100m3/D
  • Painting wastewater treatment 10m3/D
  • Machinery and chemical plant wastewater treatment 100L/D
  • Dairy farm wastewater treatment 10 m3/D
We can design a system according to the existing facilities, treatment volume, and site conditions, so please contact us.

To calculate treatment capacity, we will ask you to fill out a “preliminary investigation form” and based on the form, we will measure and set conditions such as electrical conductivity, temperature, and treatment time of the sample water, so we will need individual sample information such as pH, flow rate, storage volume, and circulating/runoff water of the target water.

For the determination of the purification feasibility of various wastewater treatment methods and the study and selection of purification methods, we conduct water quality laboratory tests according to the water quality conditions at each site and design the system accordingly.

Water treatment data varies greatly depending on water quality, so removal rates are not promised.
Cost of Wastewater Purification Systems.
Because wastewater is diverse and varies widely from site to site, wastewater purification testing is required each time the wastewater changes.

Wastewater treatment testing.
We will confirm water quality measurement certification data through purification laboratory testing (for a fee) and estimate the initial and running costs of the equipment on a site-by-site basis, depending on wastewater properties, treatment volume, desired purification level, concentration, water quality items, and installation site conditions. (Purification cannot be guaranteed without water quality testing.)

Review and reduction of industrial waste.
If you are currently using dilution and discharge, incineration, distillation and concentration, or industrial waste treatment, we can try detoxification purification of raw water to reduce the amount of diluted water, fuel costs, and CO2 emissions, and achieve significant cost reduction and environmental impact reduction.
Oil-water separation, decolorization, heavy metal removal, COD treatment
Oil separation (oil processing)

High-concentration and hard-to-process emulsified wastewater, coolant, or engine oil is separated for oil and water. The amount of sludge generated is small.
