Wastewater Treatment Services

In the past, factories, restaurants, and other establishments with special wastewater needs struggled with the complexity and cost of dealing with foul odors, oil recovery, and the cleaning of drain pipes. ECOJOHN® uses bioremediation, an approach that applies the power of microorganisms, to solve these and other problems associated with on-site wastewater treatment.

A complex biopreparation effective in breaking down oil, reliably and swiftly clears away the oil that is the source of foul odors. Furthermore, wastewater is treated using only existing facilities, so this approach is both simple and economical in its undertaking.

Biopreparation effectiveness against the pollutants in the wastewater is verified in treatability testing. Through meticulous consultation and an on-site plant survey, we develop and propose a treatment plan optimal for the customer's needs. Treatment devices are installed in accordance with the treatment plan and a test run is performed to establish optimal operation.
Operation is regularly monitored, and biopreparation and microorganism nutrients are added, to maintain treatment effectiveness.
Bioremediation is a low-cost, environmentally friendly approach for removing or neutralizing oil, VOCs, and other contaminants.

Various approaches - such as excavation, absorption, and chemical decomposition - can be taken to clean up contaminated soil and groundwater. Bioremediation enlists the functions of microorganisms and plants to remove or neutralize oil, VOCs (volatile organic compounds), and other pollutants in soil and groundwater. Excellent cost performance and low impacts on ecosystems have made it the focus of growing interest in recent years. Comparison of Bioremediation with Other Soil and Groundwater Remediation Approaches

Superior Oil / VOC Decomposition

A vast array of microorganisms exist in the soil, sea, groundwater, and other parts of the natural environment. Among them are organisms that consume oil and VOCs, and break them down into water and CO2. Bioremediation makes the most of the action of these microorganisms to efficiently remediate contaminated soil and groundwater.

Decomposition of Pollutants by Microorganisms

Cyclonic Bioreactor System
Oil Contamination Treatment

Cyclonic Bioreactor System:
  • Oxidation Tank - Inside the oxidation tank a pump effectively stirs the mixture of oil, biopreparation, microorganism nutrients, and oxygen to promote the decomposition of oil by microorganisms. Biopreparation and microorganism nutrients are periodically added to the tank to ensure stable biodecomposition.
  • Settling Tank - The settling tank is where microorganisms are separated from treated water. The sludge that settles out of the treated water is returned to the oxidation tank to ensure a stable volume of microorganisms there.
  • Sand Filtration Tank - The purpose of the sand filtration tank is to capture the cell bodies of microorganisms on the surfaces of sand grains, and to remove all traces of oil from the water being treated. Trapping organic matter arising from the decomposition process purifies the treated water.
Treatment of Hydrogen Sulfide and Other Water Contaminants:
  • Addition of Biopreparation and Alteration of Existing Facilities - We add biopreparation to existing wastewater treatment facilities to reduce organic sludge, and eliminate foul odors. To maximize the effectiveness of the biopreparation, and economically improve environmental hygiene, we can modify existing wastewater treatment facilities.
