T he performance of a water softener is dependent on two key components; a resin bed that cleans the water and precision equipment that cleans the resin. The two most significant elements that differentiate one softener from another is the volume of resin and the type of control valve.
The Resin Tank – This contains media called resin. The resin attracts and collects minerals from hard water. Once the resin is saturated with hardness minerals it must be cleaned and regenerated. Once regenerated, the resin is ready to remove more minerals from the water.
The Control Valve – This routes the water flow through the system and controls the operating cycle. Hard water passes through the resin bed to become soft. During regeneration, water flow is reversed to clean the resin bed. Brine is pulled in and then rinsed out to regenerate the resin, preparing it to soften more water. The brine tank is then refilled with fresh water for future cycles.
The Brine Tank – This stores salt and water to make brine which is used for regenerating the resin. Resin can be regenerated with sodium from salt or potassium from potassium chloride.
How Reverse Osmosis Works
- Prefiltration: When water first enters the R.O. system, it flows through a prefilter that protects the automatic shut-off and the membrane from clogging with debris. The job of the prefilter is to filter out larger particles such as silt, rust or scale, extending the life of your R.O. membrane and allowing it to tackle the smaller contaminants.
In a higher output T.F.C unit, the prefilter also has activated carbon in it. Not only does the porous activated carbon remove chlorine particles, (which is necessary to protect the refined T.F.C. membrane), it serves to filter out other contaminants as well.
- The Membrane: Water then travels to the operational center of the system - the membrane. Here, most particles too small to be trapped by the prefilter are removed from the water stream and rinsed to the drain.
The membrane's microscopic pores allow Hydrogen and Oxygen molecules through, (and water is H2O). The majority of the dissolved solids and other contaminants are flushed into the drain's water stream and exit the system.
- The "Final Polish": After the membrane, the R.O. water is routed to the holding tank. The automatic shut-off tells the system when it's time to make more water. When you turn on the faucet and draw water from the holding tank, it then goes through its final stage of filtration, a carbon filter, to remove any remaining tastes and odors before reaching your glass. This adds a "Final Polish" to your water.
Water Problems & How We Solve Them
Many water supplies require more improvement than simply removing the hardness from it. Your water may have other problems such as:
- Odor – such as sulphur or rotten egg smell
- Tainted Color
- Bad Tastes
Aqua Systems has been treating all sorts of problem water supplies since 1959. Systems can be built in a standard format with one treatment chamber, or now systems can be built as a Multi-Chambered unit to allow for multiple treatments in the same system. Listed below are some of the types of media that can be used, and what problems they treat:
- Manganese Greensand: For control of Iron, manganese, and low levels of hydrogen sulfide. The unique feature of this media is that it will both oxidize and remove iron. This media requires regeneration with potassium permanganate.
- Birm: For removal of iron and manganese in waters with a high level of dissolved oxygen. Birm works best when combined with air-injection to oxidize iron prior to entering the filter bed. This media is maintained by simple backwashing.
- Filter Ag: For removal of particulates, and improvement of cloudy water. Filter Ag is also easily maintained by simple backwashing.
- Activated Carbon: For the removal of dissolved chemicals from municipal, or other chlorinated water supplies. With simple backwashing, activated carbon can provide years of trouble-free chemical removal. This media is especially effective at removing chlorine.
- Calgon Centaur Carbon: Specially formulated carbon for the removal of chloramines, and higher levels of hydrogen sulfide. This media provides both a catalytic and an adsorptive reaction. Centaur is especially effective in applications where iron and sulphur are present, and is maintained by simple backwashing.
- KDF: A patented media that is excellent in removing Chlorine, Hydrogen Sulfide, and Iron. KDF also has a bacteriastatic quality that prohibits bacteria from growing in the media. This media is NSF certified to ANSI/NSF standard 61, and is maintained by simple backwashing.
- pH Control: A mix of calcium carbonate and magnesium oxide can be used to correct low pH that can destroy plumbing fixtures. This media is maintained by simple backwashing, and over time, adding additional media is usually required.
- Tannins: Tannins are organic compounds that cause discoloration of water. Tannins are removed by using an ion exchange (Tannin) media. This media requires salt to regenerate, but will not soften water.
- TN Combo: If Tannins are present in water along with hardness, a TN combo unit can be used. A TN combo unit uses both the Tannin resin and the standard Softening resin together in the same tank. Each resin is regenerated with salt.
