EGR is a high-rate anaerobic treatment system to treat organic wastewater. EGR achieves utilization of biomass energy, reduction of sludge produced from the treatment and saving of running cost.


1. Applicable to a wide range wastewater concentrations
EGR can successfully treat lower COD concentrations of wastewater for which conventional systems cannot be applied and creates biogas from that initial feed wastewater.

2. Biogas
By applying our technical knowledge based on our abundant experience in anaerobic treatments, the system maximizes production of biogas. The biogas can be collected and utilized as an energy source.

3. Reducing volume of sludge to be disposed of
Our innovative technology brings significant reduction in sludge volume.
