It is important to filter the water before injecting it into the sewer system. Filtration is used to protect taps, water heaters, pumps, water tanks, washing machines and other technical installations as well as pipes. But it also removes various impurities and odors from the water.
Why water filters?
Rainwater is collected on the roof and stored in tanks, but it does not meet the quality standards to be used directly for showers, washing machines or gardening.
Animals react negatively to the degradation of drinking water that comes directly from the rain tanks without filtration!
The rainwater filter can produce clear water and makes it possible to use rainwater in the house.
Which water filters to use?
In general, there are two or three filters at the pump outlet:
The particle filter with a size of 90 microns
This filter is actually called a pre-filtration cartridge. In all installations, you need a filtration of fine particles (rust, limestone, sand, films). Anything larger than 90 microns will be filtered.
The 25 micron filter cartridge
Rainwater is suitable for flushing toilets, washing machines and the garden. For applications requiring high quality, it is sometimes necessary to use an extra fine filter.
The charcoal filter
The granular coconut shell activated carbon filter filters out water pollutants such as chlorine, organic pollutants, pesticides, taste and odor alterations and fine particles. The filter also removes oils and flavors, organic matter, insecticides and solvents.
Activated carbon is especially suitable for filtering out trace organic substances, such as pesticide residues, drug residues, but also undesirable taste-altering substances, such as chlorine compounds. All compounds bind to the activated carbon by adsorption (i.e. deposition on the surface). Consequently, the cartridges must be replaced at regular intervals.
