Commercial-scale evaporative cooling systems, often known as Wet Walls, reduce greenhouse temperatures dramatically for a fraction of the expense of an HVAC system. Commercial reverse osmosis filters are an important part of Wet Wall evaporative cooling systems because they protect equipment, improve efficiency, and cleanse waste water. Foggers and misting machines, for example, profit from the use of contaminant-free, pure reverse osmosis water.
Increasing Wet Wall Evaporative Cooling Efficiency with Reverse Osmosis
A Wet Wall pump, for example, circulates water across a large, air-permeable cellulose pad while motorised fans force warm air through, resulting in cooling evaporation. The only water that should ever be used in a Wet Wall system is mineral-free reverse osmosis water, which is free of the salts and scale that foul and eventually damage the cellulose wall. If the walls start to crumble, the cost of electricity rises as the fans and pumps have to work harder to transport less water and air across the system. Also, the Wet Wall’s water continually recirculates, but eventually evaporates over time and should be topped off with pure RO water, only.
Treating Evaporative Cooling Tower Blowdown Water
Blowdown water discharged from cooling towers can be treated with commercial reverse osmosis systems. Because of the continual evaporation that leaves minerals in the tower water, this water might have a high TDS. Furthermore, water evacuated from cooling towers may include biocide, scale-inhibiting chemicals, or dangerous microorganisms, rendering it unfit for reuse.
Reverse Osmosis Return on Investment
The ROI formula is straightforward
Filling and topping off evaporative cooling systems and other atomized water applications with reverse osmosis treated water extend the life of the cooling equipment while also lowering chemicals, power costs, and system maintenance. The upfront cost is modest as compared to the possible damage and inefficiency costs associated with untreated water.
