Orival Cooling Tower FiltrationWater chemistry is routinely addressed in cooling systems. Scale formation, corrosion and biological growth are just some of the activities that can be abated by proper use of chemical additives. Foreign matter in the form of suspended solids though, is too often overlooked in the design stage. Control of this physical problem is generally addressed sometime after operation has begun when heat transfer efficiency starts to decline. Mechanical filtration is often an economical fix for this problem.
