Filtration of liquids must be supplied from a direct water source; which can vary in regards to location and water supply. Depending on the location or distribution of such fluids, the materials used to facilitate the flow of these fluids must be rust proof and corrosion resistant. [1] Among the popular choice of materials, copper is the most commonly used element which has distributed safe drinking due to its strong characteristics resisting natural wear. In most industrial and non-commercial usage, copper piping used for fluids can also be insulated with sleeving or wrapping with polyphenylene ether pipe sleeves to grant additional protection. [2] Some alternatives to metal depending on independent usages, can include water pipes made with polvinyl chloride pipes (PVC), cross-linked polyethylene (PEX), and acrylonitrile butadiene styrene (ABS). This category of pipes utilizes plastic as they durable and can easily conformable; while being able to withstand high pressures and prevents rust or corrosion. [3]Throughout the D.E. filter, similar copper piping is utilized, to maintain the purity of water flow as it undergoes the filtration process.

Diatomaceous Earth Filtration Efficiency Requirements

Filtration Process

Diatomaceous Earth (DE) filtration is a special filtration process that removes particles from water as it passes through a layer of fossilized remains of microscopic water organism called diatoms. These diatoms are mined from diatomite deposits which are located along the Earth's surface as they have accumulated in sediment of open and moving bodies of water. Obtained Diatomaceous Earth is then purified using acid leaching or liquid-liquid extraction in order for it to be used in any form of application. The process of D.E. filtration is composed of three main stages: precoating, body feed, and cleaning.

Diatomaceous Earth (D.E.) filters can be modified based on the planned function of this filter, but all basic D.E. filters are composed of similar parts. The process first begins with a direct pipeline to a raw water source, in which the water flow can be continuously controlled. Throughout the whole mechanism, it is recommended to use copper metal pipes as it is corrosion resistant. As it flows through these pipes, water reaches a second point in which
