Our OneAdvanced sewage treatment system offers a more refined approach to wastewater management with an additional sludge return feature to ensure optimal efficiency. Here’s how it works:

1. Charging Phase
   The process begins with the charging phase, where wastewater inflow from the primary chamber is air-siphoned into the secondary treatment chamber. This phase ensures that the system efficiently manages the inflow while preparing for treatment in the secondary chamber.
2. Aeration Phase
   Once the secondary chamber is charged, the aeration phase begins. Just like in the One2Clean system, oxygen is pumped into the water using a diffuser. The oxygen boosts the activity of natural bacteria, which work to break down the organic waste in the water, cleaning it efficiently.
3. Settling Phase
   After aeration, the system enters the settling phase, allowing the heavier solids to sink to the bottom of the tank. This leaves the cleaner, treated water at the top of the secondary chamber, ready for the next step.
4. Discharge Phase
   In the discharge phase, the treated water is air-siphoned out of the system and discharged through the outlet, making it safe to release into the environment. This phase operates just like the One2Clean system, ensuring clean, non-polluting water is consistently produced.
5. Sludge Return
   A unique feature of this advanced system is the sludge return phase. Any sludge that has accumulated at the bottom of the secondary chamber is air-siphoned back into the primary chamber. This keeps the system running smoothly, ensuring the secondary chamber remains efficient for future treatment cycles.

Once the sludge is returned, the entire process starts over, ensuring a continuous cycle of effective wastewater treatment.

Our advanced system is ideal for those seeking a high-performance, low-maintenance solution that ensures cleaner water and better system efficiency.
