Franke filter Germany Franke model Franke price

Franke filter wastewater treatment filter is suitable for the separation of solid suspended particles in liquids, especially in toxic media. The wastewater treatment filter mainly treats sewage to enable its reuse, effectively removing suspended solids with stable filtration precision. Application scenarios for wastewater treatment filters include water supply and drainage systems in the metallurgical industry—continuous casting and rolling water systems, blast furnace water systems, turbid and clean circulating water systems, and makeup water systems; steam turbine cooling water systems in the power plant industry; boiler wet cooling water systems; cooling water systems for large air compressors, large oxygen generators, and large air conditioners; once-through cooling and filtration systems for steam turbines using seawater, lake water, and river water. It is also widely used in agricultural drip irrigation systems.

Franke filter applications

Filtration of industrial water—requires specific water quality standards. For example: filtration of water for steel plant oxygen lances, boilers, and heat exchangers, which can remove impurities from the water to prevent clogging of pipelines and nozzles. Industrial circulating water filtration systems. Raw water treatment—can filter surface river water, lake water, seawater, reservoir water, well water, and municipal tap water used for differentiated water supply in urban residential areas, removing sand, suspended solids, algae, organic matter, etc. Agricultural irrigation—especially suitable for high-flow water sources with good impurity content, such as farmland irrigation, and irrigation of lawns in parks and golf courses. Food processing industrial water, paper industry, treatment of industrial circulating water in power plants, pretreatment of pure water for industrial and medical use. Recirculation of industrial production water, industrial wastewater treatment. Aquaculture, swimming pools, and water parks industries.

Franke filter functions

It is a set of equipment widely used in the filtration industry, overcoming many disadvantages of traditional filtration products such as low dirt holding capacity, susceptibility to clogging by contaminants, the need to disassemble and clean the filtering parts, and the inability to monitor the filter status. It features the function of filtering raw water and automatically cleaning and discharging waste from the filter element. It consists of a housing, multiple filter elements, a backwash mechanism, an electrical control box, a gearbox, electric valves, and a differential pressure controller. A horizontal partition plate inside the housing divides the interior into upper and lower chambers. The upper chamber is equipped with multiple filter elements, which utilizes the filtration space and significantly reduces the filter volume. The lower chamber is installed with a backwash suction disc. During operation, the turbid liquid enters the lower chamber of the filter through the inlet, then passes through the partition holes into the inner cavity of the filter elements. Impurities larger than the filter element gaps are retained, while the clean liquid passes through the gaps to the upper chamber and is finally discharged from the outlet.

Franke filter features

Effectively removes suspended solids with stable filtration precision. The filter element is a specially made stainless steel mesh, performing media-free mesh filtration without the need for regular replenishment of filter media. Continuous filtration during cleaning ensures no flow interruption, low water consumption. Cleaning time and differential pressure can be set according to water quality, and manual cleaning start is available. Compact structure saves space, simple operation and maintenance, high quality, low maintenance requirements: Products comply with corresponding quality standards, and all products undergo simulated operating condition testing and trial runs before leaving the factory. No special tools are required, and there are very few spare parts; easy to use, requiring only regular inspections with almost no daily maintenance. The new plastic filter elements are robust, wear-resistant, corrosion-resistant, and rarely scale. Verified by years of industrial practical use, they show no wear after 6~12 years of use, do not age, and their filtration and backwashing performance do not deteriorate over time.
