There are several common methods used for industrial water filtering, depending on the specific contaminants and the desired level of water purity. Here are a few widely used techniques:
1 . Sedimentation: Sedimentation involves allowing suspended solids to settle at the bottom of a container, typically a settling tank. The clarified water is then drawn from the top, leaving the sediment behind.
2 . Filtration: Filtration uses different types of filters to physically separate impurities from the water. Various filter media are employed, such as sand, activated carbon, diatomaceous earth, or multimedia filters containing layers of different materials. These filters can remove particles, organic matter, and certain dissolved substances.
3 . Membrane Filtration: Membrane filtration employs semi-permeable membranes with tiny pores that allow water molecules to pass through while blocking contaminants. This method includes techniques like reverse osmosis (RO) , nanofiltration (NF) , and ultrafiltration (UF) . RO is particularly effective in removing dissolved salts and other contaminants, while NF and UF are useful for removing larger particles, bacteria, and some dissolved substances.
