Industrial Control System

Smart Water Treatment System

The Smart Water Treatment System (SWT-6000) deploys a control philosophy of "centralized management, decentralized control, and resource sharing", to achieve production control, operational management, and monitoring throughout water treatment process. The system provides not just reliable hardware, but also a robust, dependable, and user-friendly software platform. The human-centric design of the development and application software renders operation and maintenance proves to be cost-effective and convenient.

The Intelligent Water Treatment System, based on water treatment process research, guarantees the safety, reliability, and continuity of the water treatment control process. Drawing on years of experience in the water treatment industry and engineering, we offer customers advanced automation solutions to enhance the level of automation.

Water Purification Process

The water source first passes through the primary pumping station (or water intake pumping station) and enters the water treatment plant. After pre-disinfection, it enters the coagulation and sedimentation tank where coagulation and sedimentation take place. The water then flows into the filtration tank, which is an important part of the water plant and is used to remove suspended solids from the water. During the filtration process, functions such as maintaining a constant water level in the filter tank and performing backwashing (using air, water, and a mixture of air and water) are carried out. The water then flows into the clear water tank, undergoes post-disinfection, and is finally pumped to the city's distribution network by the secondary pumping station. 

Wastewater Treatment Process

Wastewater first enters the treatment plant via an interception well, which only permits manageable wastewater to proceed. It is then filtered through a coarse bar screen to remove larger debris, and subsequently elevated using pump stations. The wastewater proceeds through a fine bar screen, which captures smaller debris, and a grit chamber that separates sand from water and removes larger inorganic particles.

It then reaches the bio-reactor where biological treatment techniques are employed to eliminate BOD5 (Biochemical Oxygen Demand, SS (Suspended Solids), and various forms of nitrogen and phosphorus. Then it proceeds to the secondary sedimentation tank, where the sludge formed in the bio-reactor is settled, followed by a filtration tank that further reduces SS and enhances the effluent quality. The final stage involves passing through the disinfection tank to kill any bacteria before the treated water is discharged.

The sludge pump room directs part of the sludge discharged from the biochemical pool and the secondary sedimentation tank back to the biochemical pool as return sludge. The remaining sludge is transported to the sludge dewatering room for external transport after dewatering.
