Case Study

Beverage Plant Filtration Optimization

A major international beverage bottling plant encountered significant operational bottlenecks due to heavy raw water impurity loads across their regional facilities. By integrating our specialized high-water-efficiency membrane elements directly into their primary treatment lines, they successfully reduced total fluid consumption by 30 percent while accelerating overall production output by 20 percent. This major engineering milestone powerfully demonstrates our capability to engineer tailored, high-performance purification solutions that maximize industrial productivity and resource conservation.

Large-Scale Seawater Desalination Deployment

Facing severe, chronic regional water scarcity, a massive municipal infrastructure project in the Middle East selected our advanced seawater desalination membranes for their primary production facility. Operating under extreme pressure and salinity conditions, our membrane modules achieved an astonishing 98 percent salt rejection rate, reliably delivering millions of gallons of crystal-clear potable water to over 1 million local residents. This large-scale undertaking highlights our undisputed technical competence in resolving critical humanitarian and industrial water crises worldwide.

Antipollution Municipal Water Treatment

In an effort to upgrade municipal safety standards, a prominent municipal water treatment authority partnered with Hangzhou Haina to deploy our heavy-duty antipollution membranes across public purification channels. The installation resulted in an exceptional 40 percent reduction in stubborn chemical contaminants and organic pollutants within the municipal supply. This vital public health initiative completely ensured strict regulatory compliance with international safety codes, highlighting our unwavering corporate dedication to ecological protection.
