Sediment (Dirt, Rust, Sand) Water Treatment
What is Sediment (Dirt, Rust, Sand) Filtration?Sediment Filtration is an effective method for reducing turbidity in water caused by the presence of suspended solids such as silt, sand or clay. Sediment Filters remove suspended matter such as sand, dirt, rust, loose scale, clay or organic material from the water. Untreated water passes through a filter medium which traps suspended matter. Sediment filters can remove insoluble (not dissolvable) or suspended iron and manganese. Drinking Water Treatment using Sediment Filtration is one option for a home owner to treat water problems. Sediment filters are often used with other processes such as activated carbon filtration, reverse osmosis, aeration, ozonation and chlorination.
What problem does sediment cause?Sediment can damage plumbing and appliances over time. It includes rust particles that can cause brown, yellow or orange spots on clothing, fixtures and toilets.
How do I select a Sediment Filter?Selecting a sediment filtration unit should be based on water analysis and individual needs. When selecting a sediment filtration device, you should consider the flow rate, the filter material, the estimated amount of water it can effectively treat and the water quality desired (filter rating). Most filters are rated according to the smallest particle they can trap. For example, a 10 micron (10 thousandths of a millimeter) filter would trap contaminants 10 microns in diameter or larger. In general, the largest rating size that will remove the intended contaminants will require the least maintenance. Regular replacement of the filter/cartridge is an important factor in maintaining effectiveness and reducing bacterial contamination of the filter.
What contaminants are not removed by sediment filtration?Sediment filters alone do not effectively remove dissolved organic or inorganic material that may be harmful. They do not effectively remove nitrate, heavy metals, pesticides or trihalomethanes. Cartridge sediment filters are not generally recommended for removing microbial contaminants.
Do I need POE or POU Sediment Filtration?When sediment is an issue with water-using appliances such as washing machines, dishwashers, or water heaters, Point-of-Entry (POE) sediment filters may be used to treat all water at its entry point into the home. For drinking water filtration, Point-of-Use (POU) devices can be installed under the sink or attached to a tap. Sediment filters are often used as a pre-filter for other water treatment processes to increase their effectiveness and longevity.
