Bio-Robi® Transform wastewater into safe and clear water
The high performance, low maintenance wastewater treatment solution for small sites.
Effective, environment-friendly onsite solutions for domestic wastewater treatment - saving water and contributing to a cleaner environment.
Bio-Robi® is a novel, patented environment-friendly solution that converts domestic sewage into clean, odorless effluent for reuse in irrigation or other applications. Efficient Bio-Robi ensures minimal sludge accumulation, requiring removal only once every few years. While normal septic systems can achieve up to 60% reduction in BOD & TSS, the effluent produced by Bio-Robi is 95% – 98% clean! The reliable system offers superb ease of operation and low maintenance.
Bio-Robi's unique purification process effectively handles sewage on small sites. The versatile system is especially suited to:
♦ Family dwellings
♦ Small communities
♦ Government Facilities
♦ Gas stations and truck stops
♦ Camping grounds and trailer parks
Bio-Robi is an ideal solution for rural areas or areas without central sewage systems. With Bio-Robi, there aren't any unsafe chemicals or unpleasant odors. The system is particularly effective in regions with poor soil absorption or in water reuse areas.

Three efficient steps that turn wastewater into clean water:
Bio-Robi's effective system leverages the power of nature coupled with smart technology to purify wastewater and transform it into clean water that can be reused for irrigation -saving water and contributing to a clean environment.
1. Pre-treatment
The sewage inflow collects in the septic tank. Anaerobic digestion is utilized during the initial sedimentation process, achieving up to 60% reduction of BOD & TSS.
2. Purification
The inflow wastewater from the pre-treatment tank is mixed with compressed air in a special static mixing chamber on top of the tank. The extended aeration process achieves high levels of dissolved oxygen (4-6 p.p.m.), enabling the bacteria to digest the organic load and purify the sewage.
3. Clarification
Treated effluent flows to the final clarification tank. The remaining suspended particles sink to the bottom of the settling tank and are pumped back for additional purification. The clean, odorless effluent can be used for irrigation and other water reuse applications.
The discharged water is between 95% – 98% clean and is suitable for reuse. Water used for subsurface drip irrigation or for an absorption drain field does not require further treatment.
