In 2022, Xinxiang Huaqing Environmental Equipment Co., Ltd. reached an equipment supply cooperation with China State Construction Fifth Engineering Bureau (CSCEC 5th Bureau), delivering a batch of automatic disc filters for recycled water treatment and municipal landscape water renovation projects of multiple green construction sites under CSCEC 5th Bureau.
CSCEC 5th Bureau commits to low-carbon and zero-waste construction standards. Its rainwater recovery and construction wastewater reuse systems demand filters with high automation, strong sediment resistance and low maintenance cost. Huaqing customized multi-unit combined disc filter skids equipped with dual-mode automatic backwashing controlled by pressure difference and timer. The backwashing water consumption is less than 1% of total flow, effectively intercepting sediment, suspended solids and construction residues to prevent pipeline and spray nozzle blockage, ensuring year-round stable operation of water circulation systems.
The filters adopt anti-corrosion engineering plastic discs and carbon steel anti-rust shells, suitable for outdoor harsh environments. Modular design saves space and enables quick installation. All equipment passes full hydraulic and automatic control tests before delivery, with on-site commissioning and full-cycle after-sales technical service provided.
After implementation, the construction sites achieved a remarkable rise in water recycling rate, cutting tap water consumption and sewage discharge, fully matching CSCEC’s green construction strategy. This cooperation built a solid long-term partnership, and Huaqing has continued supplying complete filtration solutions for CSCEC’s water conservancy and real estate projects ever since.
