Application
The domestic sewage treatment equipment is designed for projects that only require small-scale wastewater treatment plants.
(1) Sewage treatment for hotels, restaurants, nursing homes and hospitals.
(2) Sewage treatment for residential quarters, villages and towns.
(3) Sewage treatment for railway stations, airports, seaports and on ships.
(4) Sewage treatment for factories, mines, military bases, and tourist destinations.
(5) Sewage treatment for various industrial wastewater which similar to domestic water.

Our domestic sewage treatment equipment utilizes an effective A/O （Anaerobic/Oxic）process for wastewater treatment.

The buried integrated wastewater treatment equipment includes a hydrolysis tank, two aeration biological contact oxidation tanks, a sedimentation tank, a disinfection tank, and a fan room.

The control system is fully automatic and starts and stops at user-configured times. Our equipment is suitable for automatic operation without the need for constant supervision.

Features
(1) Minimal volume: Our ZWF1 type wastewater treatment plant is intended to be buried below the ground. The ground above the equipment can be built into greenspace, and there is no need for other supporting houses, e.g. heating units or other auxiliary devices.
(2) The treatment is stable and efficient: Blast aeration is adopted in the secondary biological contact oxidation process. This technique decreases the amount of activated sludge, and adds to equipment adaptability for various wastewater types. The effluent water quality is stable, and no sludge surge will occur.
(3) Easy to maintain: The entire processing equipment generally does not require constant maintenance but only periodic regular maintenance.
(4) Strong adaptability to changes in wastewater composition and quantity.
(5) No odor output: The machinery features an aerobic treatment process and is embedded underground to eliminate the chances of odor leakage.
(6) The compact structure provides excellent mobility and transportation if necessary.

Customization Notes
Please provide the composition data of wastewater and the throughput of water to be treated. If you cannot provide such data, please tell us about your intended use and wastewater type, and we will design the equipment as needed.
