Cooling Tower for Wastewater Treatment

Product Overview

The Cooling Tower for Wastewater Treatment is an efficient cooling system designed specifically for wastewater and reuse water applications. It lowers the temperature of process water or recirculated wastewater through evaporative or closed-circuit cooling methods, ensuring the stable operation of downstream treatment processes. The tower is highly resistant to corrosion and fouling, suitable for various complex water qualities.

Working Principle

The cooling tower achieves heat dissipation through the exchange between water and air. Warm wastewater is evenly sprayed over the filler layer, where it contacts the upward airflow. A portion of the water evaporates, carrying away heat and lowering the overall water temperature. In closed-circuit types, heat is transferred indirectly through coils, preventing contamination and scaling.

Main Components

• Tower body (FRP, stainless steel, or galvanized steel)

• Filler assembly (PVC or PP corrugated type)

• Fan system (axial or centrifugal)

• Spray and water distribution system

• Drift eliminator and water collector

• Temperature control and electrical system

Features

• Corrosion resistant: Suitable for saline, acidic, or organic wastewater environments

• High efficiency: Optimized air-water ratio for superior cooling performance

• Low noise: Quiet fan and aerodynamic tower design

• Easy maintenance: Modular construction for convenient cleaning and servicing

• Versatile application: Compatible with a wide range of wastewater and reuse systems

Applications

Widely used in wastewater treatment plants, reclaimed water systems, electroplating, chemical, textile, paper, and pharmaceutical industries for cooling recirculated wastewater or process liquids.

Optional Configurations

• Open or closed-circuit cooling design

• Automatic water make-up and temperature control system

• Anti-scaling and anti-blocking spray system

• Optional stainless steel or FRP housing

• Noise-reduction silencer system

• PLC automation and remote monitoring function

     Jiangsu Sanhe Environmental Protection Group Co., Ltd., formerly Jiangsu Sanhe Environmental Protection Equipment Co., Ltd., is located on the scenic shores of Lake Taihu. It is a renowned manufacturer and developer of modern environmental protection and water treatment equipment in China. It comprises several subsidiaries, including Jiangsu Sanhe Environmental Engineering Co., Ltd. and Yixing Sanhe Environmental Protection Design Institute Co., Ltd. The parent company has a registered capital of 100.2 million yuan, a building area of ​​over 20,000 square meters, and a staff of 52 technicians. The company boasts not only strong environmental protection equipment production and R&D capabilities, but also a highly qualified team with over 30 years of experience in environmental protection equipment production and service, a passion for environmental protection, and a commitment to integrity.

     After nearly 30 years of continuous effort, our innovative development of new products, technologies, materials, and processes, along with our expertise, has been widely adopted in the industry. We have developed advanced continuous-flow activated carbon filters and differential fully automatic backwash filters specifically for reclaimed water reuse and zero-discharge projects. We have also independently developed high-efficiency activated carbon suitable for flow-through activated carbon towers, resolving challenges in China due to poor adsorption performance, short service life, saturation, and high operating costs, hindering widespread adoption and ensuring long-term effective use of activated carbon.
