sand filter tank
A sand filter tank is a sophisticated water treatment system that employs layers of specialized filtration media, primarily sand, to remove contaminants from water. This essential equipment operates through a mechanical filtration process where water passes through multiple layers of varying grain sizes, effectively trapping particles, debris, and microorganisms. The system typically consists of a pressure-rated vessel, internal components for water distribution, and carefully selected filter media layers. Modern sand filter tanks incorporate advanced features such as automated backwash systems, pressure monitoring devices, and precise flow control mechanisms. These tanks are extensively used in swimming pools, municipal water treatment facilities, industrial processes, and agricultural applications. The filtration process begins when contaminated water enters through the top distribution system, flows through the filter media beds, and emerges as clean water from the bottom collection system. The multi-layer media arrangement, typically consisting of gravel, coarse sand, and fine sand, ensures comprehensive filtration at different levels. This systematic approach allows the sand filter tank to effectively remove particles as small as 20-40 microns, providing reliable water purification for various applications.
