Gravel filters represent a highly effective solution for removing both organic and inorganic impurities from water. Their key advantage lies in a superior dirt-holding capacity, allowing a significant layer of sediment to accumulate on the filter media without compromising flow. This makes them far more effective at retaining contaminants compared to various screen or laminated filters.
A major operational benefit of multi-tank gravel filter systems is their ability to provide an uninterrupted water supply. When configured in parallel, clean water from one or more tanks can be used to backwash others, ensuring continuous operation. The total filtration flow rate scales directly with the number of tanks connected in parallel.
Given their effectiveness, gravel filters are the recommended choice for any water source containing organic matter, irrespective of the inorganic load.
