Water Filters Whole House - Various Types of Whole House Water Filters

filtration system sediment bacteria

Whole house water filters are expressly manufactured to accommodate the higher water flow rate originating from the incoming water line of home. Increasing the water flow reduces the efficiency of the filter. Select a system that can successfully process your water flow rate.

There are various categories of whole house water filteration systems all of which pre-filter sediment, particularites, rust and dirt. This pre-filtering will increase the clarity and taste of the water in addition to protecting the plumbing. Removing sediment extends the life of the carbon filter and prevents damage to the equipment.

This article will cover the specifics of the various systems.

Sediment Filtration
The sediment filter will remove dirt, rust and sediment from the water in addition to numerous particulates from both well and city water supplies. Clarity and taste are improved in addition to preventing damage to plumbing. Without sediment filtration, water flow may become restricted and become a host for bacteria. Rural areas in proximity to streams, wells and agricultural pollution are well served with this filter.

Carbon Filtration
This filtration system removes chlorine, chloramine and various chlorine by-products in addition to removing bad taste, odors and volatile organic compounds (VOC) that may be harmful to our health. The Environmental Protection Agency (EPA) estimates at least 20% of the United States water supply contain VOC’s. Some common pollutants include benzene which seeps into the water supply, dichloromethane which is used as an industrial solvent and tetrachloroethylene, a chemical used for dry cleaning.

After filtration, Ultraviolet (UV) disinfection is recommended to prevent bacteria growth.

Reverse Osmosis (RO) Water Filtration
Reverse osmosis, otherwise knows as hyperfiltration is the most popular filtration system in use. It is widely used to treat drinking water. It successfully removes the widest variety of toxins including particles as small as an ion. Its membrane has pores approximately .00005 microns in diameter. For comparison, bacteria is .2 microns in diameter and viruses are .02 microns in diameter.

Iron Water/Hydrogen Sulfide Reduction Filtration
Water supplies with high iron content will benefit from this filter. Manganese and hydrogen sulfide is removed as well. Contaminants are removed through oxidation and carbon filtration. The surface of the carbon particles will absorb the hydrogen sulfide. This process adds no chemicals to the water and will increase the lifespan of water purification systems.

Hydrogen Sulfide is a flammable, poisonous gas with a smell resembling rotten eggs, formed when bacteria breaks down without the presence of oxygen such as a sewer or swamp. It is extremely toxic to the nervous system. It corrodes iron, steel and copper.

If bacteria and virus elimination is needed, an Ultraviolet system should be used. This system kills e.coli, coliform in addition to yeasts, cryptosporidium and giardia. No chemicals are used.

Ultrafiltration
This is a filtration system that separates suspended solids and emulsified oils from fluids. It forces liquid through a semipermeable membrane. Water passes through the membrane. Ultrafiltration has the ability to reduce 98% of the oil from water without the use of chemicals.

There are a couple of thousand water filtration systems on the market and the technology can get confusing. Your first step should be a call to your local water utility. Request their yearly report and question them as to what the add to the water supply. Ask about chlorine, Chloramine Phosphorous, MTBE and lead levels. If your water is from a well, it is wise to have the well tested by a certified laboratory.

When you decide on a water filtration system, ask about the healthy additives such as trace minerals, potassium and magnesium.
