Our sewage cooling towers are ideal for industries such as steel, chemical, electric power, food processing, pharmaceuticals, textiles, and construction, effectively managing heat in various industrial wastewater streams. 
Select a well-ventilated site free from heat sources or obstructions.
Ensure the site supports the cooling tower's weight and adheres to foundation specifications (±5mm elevation error).
Maintain adequate spacing between towers or buildings (at least one tower diameter; more for ultra-low noise models).
Design pool depth, outlet, and discharge pipes based on specific requirements if constructing independently.
Hydraulic pumps and control boxes are optional add-ons, available for purchase.
Avoid open flames or welding near the tower; take precautions if necessary.
Before operation, verify secure foundation connections, lubricate components, and check wiring.
Assign professional operators for regular inspections and maintenance logging.
Cover the tower with a tarpaulin during extended downtime to protect components.
Sewage cooling towers are engineered for wastewater treatment, featuring enhanced corrosion resistance and anti-clogging capabilities. Their components, such as PP fillers, are designed to handle the chemical properties and impurities in sewage, ensuring easy maintenance.
These towers offer high cooling efficiency, dependent on design, packing type, fan performance, and environmental conditions. Optimized designs ensure superior cooling for sewage applications.
Maintenance costs can be higher due to impurities in sewage causing blockages or corrosion. Regular cleaning and using corrosion-resistant materials can significantly reduce costs.
With proper maintenance, the service life of an open counter-flow cooling tower for sewage typically ranges from 10 to 15 years. Harsh environments or poor maintenance may reduce this lifespan.
Modern designs keep noise levels below 70 dB, with low-noise fans and soundproofing options available for stricter requirements.
Installation requires a stable foundation, proper ventilation, and sufficient spacing for heat dissipation and maintenance. Correctly sized inlet/outlet pipes are essential.
Packing should be inspected annually and replaced as needed to prevent clogging and maintain cooling efficiency.
Costs include electricity and water replenishment. Efficient fans and pumps, along with optimized water use, can lower expenses.
Regular cleaning, high-quality anti-clogging fillers, and inlet filters can effectively prevent blockages.
These towers are suitable for sewage treatment plants, chemical plants, paper mills, printing and dyeing plants, and other industries handling high-temperature, impurity-laden wastewater.
