Case Study

Municipal Water Treatment Optimization

In 2022, a major metropolitan city located in Japan faced severe challenges regarding excessive residual chlorine levels in its municipal water supply, which led to widespread public dissatisfaction. Hangzhou Haina collaborated directly with local municipal authorities to install our advanced CTO filtration units across their regional treatment plants. The operational results were dramatic, achieving over a 90 percent reduction in active chlorine levels, which significantly elevated overall water quality and rapidly restored public confidence in the local drinking supply.

Enhancing Water Quality in Residential Applications

A large residential complex situated in South Korea sought a reliable engineering upgrade to improve the quality of its domestic drinking water, which was heavily plagued by unpleasant chemical tastes and offensive odors. By seamlessly integrating our specialized CTO filters into their existing building water purification systems, they achieved a remarkable enhancement in overall fluid quality. Subsequent resident surveys reported an impressive 95 percent satisfaction rate regarding the refined taste and purity of their drinking water.

Industrial Application of CTO Filters

A prominent commercial beverage manufacturer operating in the United States encountered persistent production hurdles with incoming process water quality adversely altering their final beverage taste profile. Haina's specialized CTO filters were swiftly implemented into their primary water treatment loop, resulting in a 98 percent reduction in taste-altering organic contaminants. This technical upgrade successfully improved finished product quality while simultaneously reducing recurring operational overhead costs associated with water treatment.
