The DE Filter's operation is quite fascinating. The raw or process water is drawn through the filter and pumped into the system by the filter pump.

Piping is arranged so that the water can be recirculated via a by-pass line for precoating the elements prior to the actual filtration process. Precoating is accomplished by introducing the suitable amount of diatomaceous earth powder into the filter tank and recirculating the mixture until the filter elements are uniformly coated and the water in the tank becomes clear.

The filter pump will be manually shut down when the differential across the cake reaches 15 inches of mercury, and the filter is washed. The spent diatomite filter cake is then flushed from the elements and the DE Filter bottom.

You want to know which pool filter is right for you? Diatomaceous earth pool filters are a popular option, but they can be messy to clean and maintain.

The working principle of filtration is quite fascinating. A stainless steel filter disc is placed horizontally in a closed container, with a filter screen at the top and a support plate at the bottom.

The disc is pre-coated with diatomite, which forms a layer that traps particles and macromolecules as the liquid to be filtered passes through. This process is essential for achieving a clear filtrate.

The filter disc is designed to allow the clear liquid to pass through, while the solid substances accumulate on the surface of the filter cloth. This accumulation creates a "filter cake layer" that blocks the escape of particulate impurities.

The filter cake layer is incredibly effective, with gaps between particles so small that they prevent the liquid from becoming cloudy. This is why filtration is such an important process in various industries.

The process flow of the system is quite fascinating. It involves a series of steps that ensure the liquid is cleaned and foreign substances are removed.

Dirty liquid is first sent to the Mixing Tank, where it's prepared for filtration. From there, it's pumped into the Filter Pump, which helps to remove impurities.

The liquid then passes through the Filtration Unit, which consists of a Base Filter and Filter Aid. This is where the magic happens, and the liquid is transformed into clean liquid, which is then sent back to the system.

Here's a breakdown of the process flow:

The system is designed to be efficient and effective, with a clear path for dirty liquid and foreign substances.
