Feature-Tec Macvital® | Efficient Cooling Water Filtration
2025-07-18
What is Cooling Water?
"Cooling water" refers to water or aqueous solutions used in industrial production, machinery operation, and energy conversion to absorb or transfer heat, ensuring that systems or equipment operate within optimal temperature ranges. It circulates to dissipate excess heat, preventing overheating damage and ensuring stable, safe production processes. Based on whether it contacts the cooled material, cooling water can be categorized into:
- Once-Through Cooling Water: Drawn directly from natural water sources (e.g., rivers or lakes), it is discharged after heat absorption. While cost-effective, this method causes thermal pollution and is increasingly restricted in regions with strict environmental regulations.
- Recirculating Cooling Water: Cooled via cooling towers and recirculated back into the system. It is the mainstream method in modern industry due to its high efficiency and reduced water consumption. Corrosion inhibitors and scale inhibitors are often added to maintain system performance.
Feature-Tec has extensive experience in purifying recirculating cooling water. Industrial cooling water typically accounts for 50–60% of municipal water consumption. Power plants, chemical plants, and metallurgy industries consume large volumes of cooling water for heat exchange. However, during system operation, evaporation and wind loss concentrate the water, raising ion content, altering pH, and degrading water quality. These conditions promote microbial growth and algae proliferation, especially under sunlight exposure in cooling towers—making water treatment essential for controlling scaling, corrosion, and biological fouling.
Traditional Filtration vs. Feature-Tec Macvital® Automatic Backwash Filtration
Traditional systems like sand or multimedia filters suffer from high water consumption during backwashing and cumbersome maintenance with filter media requiring frequent replacement and difficult waste disposal. In contrast, Feature-Tec’s Macvital® system offers:
- High flow rate design
- Superior filtration efficiency
- Ultra-low backwash water consumption
- No solid waste generation
Making it an ideal replacement for conventional sand and multimedia filters in industrial cooling systems.
