Zhongmu Xincheng Water Plant

Project Name: Zhongmu New Town Water Treatment Plant

Location: Henan, China

Capacity: 75,000 tons/day

Equipment: Micro-vortex flocculation equipment, inclined tube sedimentation equipment, V-type filter with high-efficiency filter media, activated carbon filter, monolithic filter underdrain

Project Introduction:

The Zhongmu New Town Water Treatment Plant is located in Zhengzhou City, Henan Province, with a daily treatment capacity of 75,000 cubic meters. The treated water is primarily used for drinking. The plant's structures utilize reinforced concrete, and it is a government-funded and government-operated project. Construction began in 2010, and the plant became operational in 2014.

The main treatment process employed is: tubular mixer → micro-vortex flocculation tank → inclined tube sedimentation tank → V-type filter → activated carbon filter → disinfection → supply to users. In addition to the high-efficiency sedimentation tank, this project incorporates V-type filtration for the primary filtration stage and activated carbon adsorption for advanced treatment.

The V-type filter features V-shaped inlet channels and uniformly graded filter media. This distinctive structural design, combined with the precision-engineered filter media, delivers superior filtration accuracy and incorporates a surface sweep function during backwashing — producing higher-quality effluent while significantly reducing backwash water consumption. The water and air distribution system uses a monolithic filter underdrain, in which the filter underdrain channels are cast integrally with the filter's reinforced concrete structure, ensuring exceptional structural integrity. The adjustable nozzles can be precisely leveled to a horizontal plane, achieving highly uniform water and air distribution and ensuring thorough cleaning of the filter media.

For advanced treatment, the activated carbon filter utilizes underdrain blocks combined with activated carbon for deep purification, effectively removing trace amounts of difficult-to-degrade contaminants and ensuring safe, high-quality drinking water for end users.
