Firsle DM Series Intergrative Sand Filter is an integrated equipment solution specifically designed for swimming pool water treatment or sewage treatment. Its characteristic is that the main body of the buried integrated filtration equipment can be installed below the ground, saving space and making it easy to hide without damaging the overall aesthetics of the scenery. For underground integrated filtration equipment, it usually includes key components such as circulating water pumps, filters, disinfection systems, etc. These components are integrated into a compact housing and then buried underground as a whole. The buried integrated filtration equipment has efficient filtration function, which can effectively remove impurities and microorganisms in swimming pool water, and maintain clean and hygienic water quality. Its advantages include simplifying the installation process, reducing the need for building computer rooms, lowering noise, and being easy to maintain. For underground integrated filtration sewage treatment equipment, it is an integrated facility for the treatment of domestic sewage or industrial wastewater. It integrates multiple treatment processes such as physical, chemical, and biological processes, such as grid filtration, sedimentation, biodegradation, deep filtration, and disinfection, to concentrate the entire treatment process in a device that can be buried underground. This type of device has strong adaptability, especially suitable for situations with limited space and high environmental requirements.
