Diatomite filter element ，we can called deacidification filter element ,which is used for pressure oil filtration of hydraulic and lubrication systems to filter solid particles and colloidal substances in the working medium, effectively control the acid-base degree of the system, and ensure the safe and efficient operation of the system. 

Diatomite filter element is designed and produced for water removal of fire-resistant oil in power stations. It is applied to the fire-resistant oil regeneration device, which can reduce the water content to the design value in a short time and maintain continuous operation, effectively maintaining the low water content in the fire-resistant oil, so as to ensure the safe operation of the steam turbine and plan maintenance in an orderly manner. It can also be called power plant filter element

The filter element ST718-00-03ZXCO ordered by Egyptian customers is one of the core filter elements commonly used in the fire-resistant oil system of power plants. It is mainly used to modify the anti fuel, remove acid, and comprehensively improve the oil quality of the fire-resistant oil system.
