What is the commonly accepted amount of precoat for DE filters per square foot of surface area?

The commonly accepted amount of precoat for diatomaceous earth (DE) filters is 0.125 pounds per square foot of surface area. This measurement is based on the manufacturer's specifications and industry standards for achieving optimal filtration performance. Precoating with DE helps ensure that the filter medium can effectively capture debris and contaminants, enhancing water clarity and quality.

Using this specific amount allows for proper coverage and ensures that the DE filter operates efficiently without compromising its ability to trap particles. If too little DE is applied, the filter may not function effectively, while excessive amounts can lead to issues such as increased pressure and reduced flow rates, which can ultimately impact the system's operation.
