Rain Water Filtration Systems
Rainwater filters remove physical contaminants from water before it is directed to a tank or other use. Rainwater filters remove physical contaminants from water before it is directed directly to a tank or to a system for other uses such as irrigation or cleaning. These filters play an important role in systems where rainwater is collected, for more efficient use and to maintain water quality.
Rainwater, which is usually collected from roofs, terraces or other surfaces, can contain leaves, dust, mud, sand and other contaminants. Rainwater filters come into play to prevent these contaminants from entering the water tank and to ensure cleaner water use.
Filtration stages
Collection : Rainwater is collected from roofs, terraces or other surfaces.
Filtration : Collected rainwater is filtered to remove contaminants. These filters ensure that the water is clean and usable.
Storage or Usage : Cleaned rainwater is directed to the water tank and transferred to other usage areas such as reservoir, irrigation and cleaning.
Things to Consider When Choosing a Filter
There are several important factors to consider when choosing a rainwater filter:
Roof Area: Roof area affects the amount of rainwater collected and the diameter of the connection. Larger roofs collect more water and this can affect the capacity of the filters.
Rainfall: The average monthly rainfall affects the size of the system and the capacity of the filters. The average monthly rainfall is important for the efficiency of the filtration system.
Tank Selection: The purpose for which the collected water will be used and the average monthly rainfall are determining factors in tank selection. It should be selected with optimum capacity for the intended use and application area.
Mounting Options
Rainwater filters are available in two main installation options:
Above Ground Mounting: Filters are mounted on the surface of the ground. This option can be easier for maintenance and access.
Underground Installation: The filtration system is installed underground in structures such as manholes etc. This provides an aesthetic appearance and saves space.
