Decentralized Wastewater Treatment

Domestic wastewater

Modular treatment for sites without centralized sewerage

Solutions for hotels, resorts, hospitals, tourist facilities, residential clusters and other sites requiring reliable local treatment.

15–200 m³/day

Scalable capacity range for different site requirements.

Compact and modular

Designed around the available area and phased demand.

Treatment and disinfection

Process stages are selected according to influent and discharge or reuse targets.

3D-RBC system water balance

At least 97% of the water is available for beneficial reuse

For a 15 m³/day decentralized domestic wastewater treatment unit, the design water balance shows that no more than 1% of the incoming water leaves with removed sludge, while the remaining volume passes through treatment. Yuntai International therefore uses a more conservative public value: at least 97% water recovery.

15.00 m³/daydesign influent flow

≤ 0.15 m³/daywater removed with sludge — no more than 1%

≥ 14.85 m³/daytheoretical treated-water volume — at least 99%

≥ 97%conservatively stated water-recovery capability

Why state 97% when the design balance indicates at least 99%?

The difference does not represent an additional permanent water loss. A margin of at least two percentage points allows for flow-meter uncertainty, short-term load variation, maintenance, sampling and site-specific operating conditions. This makes the 97% figure conservative, verifiable and technically defensible.

Calculation: 15.00 − 0.15 = 14.85 m³/day; 14.85 ÷ 15.00 × 100% = 99%. Publicly stated value: ≥97%.

Potential uses of treated water

landscape and flower irrigation;
approved irrigation applications;
other authorized non-potable uses;
compliant discharge only after water quality is confirmed and the discharge destination is approved.

How performance is verified

The actual recovery ratio is determined from inlet and outlet flow-meter readings over the same reporting period. Treated-water quality is confirmed by laboratory testing against project requirements and applicable local regulations.

Important: 97% describes the quantity of water recovered. It is not a removal percentage for COD, BOD, nitrogen, suspended solids or microorganisms. Reuse or discharge suitability depends on laboratory results, the intended use and applicable requirements. This statement does not provide for direct discharge into Lake Issyk-Kul.
