DetailsSlow sand filters do have certain limitations. They require a large land area, large quantities of filter media, and manual labor for cleaning. Water with high turbidity levels can quickly clog the fine sand in these filters. Water is applied to slow sand filters without any pretreatment when it has turbidity levels lower than 10 NTU.
DetailsThere are primarily two types of sand filters used in the wastewater treatment process: rapid (gravity) sand filters and slow sand filters. Rapid (Gravity) Sand Filters: Use larger sand grains and operate at high flow rates. Typically include a system to wash the sand, which allows these filters to handle heavier loads.
