✦ Practical Commercial Project Case: Full Set Water Treatment System for Indoor Public Swimming Venue

#unit-cEWTtUTPdAEVDdN [ce-data-type="text"]{text-align:left;}

When summer arrives, community natatoriums and public swimming pools become popular leisure spots for residents to exercise and cool down. These high-traffic public venues impose extremely strict requirements on the stability, durability and comprehensive performance of pool water treatment hardware. A large indoor public swimming pool in Sanming, China adopted a complete set of matched pool water treatment equipment supplied by Ziying, including circulation pumps, stainless steel filter tanks, automatic chemical dosing systems, water quality monitoring controllers and air-source heat pumps. The integrated system delivers full support for stable water sanitation and year-round comfortable constant temperature for the whole venue.


1. High-Efficiency Circulation Pumps: Core Power for Continuous Water Flow
Our matched circulation pumps stand out with stable output and powerful circulating capacity. They maintain steady whole-pool water flow 24/7, rapidly carrying suspended dirt, organic pollutants and tiny impurities into filtration units. Continuous circulation effectively prevents sediment buildup, algae breeding and water turbidity, keeping pool water crystal clear all year long. In addition, energy-saving motor structures are adopted to cut power consumption greatly, realizing the balance between effective water purification and low-carbon, cost-saving operation.


⦁ Stainless Steel Filter Tanks: Reliable Core Filtration Unit
Stainless steel filter tanks act as the vital "water guardian" of the whole circulation system. Made of premium anti-corrosion stainless steel, the tank bodies can withstand humid, corrosive mechanical room environments with outstanding long-term durability. Filled with high-purity natural quartz sand filter media, the tanks efficiently trap fine dust, sediment, tiny organic particles and suspended colloids in pool water, delivering purified water that reduces skin and eye irritation for swimmers.
Equipped with user-friendly backwashing structures, the filter tanks allow simple one-switch reverse cleaning to flush accumulated contaminants and restore full filtration efficiency quickly. This design extends equipment service life and avoids frequent expensive consumable replacement, minimizing routine maintenance workload.


⦁ Intelligent Water Quality Monitors & Automatic Dosing Equipment
The intelligent water quality monitoring system works as the precise management assistant for pool operators. Fitted with high-precision sensors and advanced detection modules, it tracks key water indicators in real time, including pH value, residual chlorine concentration and water turbidity, and outputs accurate data reference for daily water management.
Cooperating with automatic chemical dosing pumps, the whole system adjusts disinfectant dosage intelligently according to actual water conditions, maintaining balanced disinfection effect and stable water chemistry. It avoids uneven chemical concentration caused by manual dosing errors, creating consistently healthy and mild water environments for swimmers of all ages.


⦁ Air-Source Pool Heat Pumps: All-Year Constant Temperature & Green Energy Solution
To offer comfortable swimming experience in all seasons, the venue is equipped with air-source pool heat pumps. The units absorb free heat energy from ambient air via high-efficiency heat exchange technology to provide stable heating for pool water. Whether in cold winter or hot summer, the equipment keeps water temperature within the ideal comfortable range.
By utilizing renewable air thermal energy instead of traditional fossil fuels, air-source heat pumps lower overall energy expenditure, reduce reliance on non-renewable resources and fit the global trend of eco-friendly, low-carbon pool operation.
