What is the function of a Horizontal High Rate Sand Filter?

The function of a Horizontal High Rate Sand Filter is to increase surface area for filtration. This type of filter is designed to maximize the interaction between the water being filtered and the sand within the filter. By employing a horizontal design and a deep bed of sand, a greater volume of water can pass through the sand, allowing for more contaminants and particles to be trapped effectively. The increased surface area enhances the filter’s ability to remove suspended solids, improving the overall water clarity and quality.

While decreasing water flow, preventing algae growth, and heating water are important considerations in pool maintenance and operation, these are not the primary functions of a Horizontal High Rate Sand Filter. Rather, the effectiveness in filtering and clarifying water is the main objective that is achieved through increased filtration surface area.
