Why use a Water Softener Element?
Calcium and magnesium are hard scale forming minerals that build up on piping, heat exchangers, water heaters, boilers and any steam related equipment. This buildup results in costly repairs, increased energy consumption by up to 30%, plugged heat exchangers and boiler tubes. The service life of linens, clothing, appliances and fixtures is greatly reduced due to these “hard” minerals.
For laundry and dishwashing, the use of a water softener element will significantly reduce the amount of soaps and detergents, resulting in reduced operating expenses.
Effects of Hard Water Problems
In other household and commercial applications, hardness also increases soap consumption wasting from 50% to 90% of the soap used, depending on the amount of hardness. It also causes the formation of soap curd, which adhere to cloth fibers, hair, glassware and dishes. Soap curd causes poor results in laundering and may hold pathogenic bacteria.
Critical Selection parameter for Water Softeners
• Water Quality Report (Especially Hardness and TDS) Water Requirements (Hourly, daily)
• Water Requirements ( Normal , peak) Water Storage capacity
PLEASE NOTE THAT AN EFFECTIVE WATER TREATMENT PROGRAM CAN CONVERT ENERGY LOSES TO ENERGY SAVINGS
What is Water Hardness?
The hardness of any supply water is determined by the contents of calcium and magnesium compounds, which exists to some degree in all natural waters. The hardness in well water is usually higher than that of surface water. Calcium and magnesium can combine with bicarbonates, sulfates, chlorides, and nitrates to precipitate as solids mineral salts make water more basic and corrosion aggressive on many materials.
Hard water is responsible for the formation of lime scaling in pipes, utensils, water heaters, boilers, HVAC systems, etc., causing inefficiency and sometimes permanent damage. Scale acts as an insulation material, thus lowering heat transmission and often causing premature heater failure due to overheating of the metal.
The presence of salts in lime scale deposits is one of the most common cause of corrosion, which cause damages in water pipelines and boilers. Any descriptive or numerical classification of hardness of water is rather arbitrary. A water that is termed hard in some areas may be considered soft in other areas.
As a general guide the following parameters may be used.
Soft : less than 60 ppm (as calcium carbonate)
Moderately hard : 60-120 ppm
Hard: 120-180 ppm
Very hard : above 180 ppm
Measurement of water hardness and either conductivity or total dissolved solids (by TDS/conductivity meters) is also performed before any softening treatments. During the water softening processes, carbonates are substituted by sodium, which does not alter the total concentration of dissolved solids.
Softener Element Regeneration — Process Theory
Initially, strong acid cation media in the sodium (Na+) form is placed into service. During the sodium cation exchange water softening process, sodium ions are exchanged for undesirable quantities of calcium (Ca +2), magnesium (Mg +2), and iron (Fe +2). Sodium ions already present in the water being softened pass through the process unchanged. Upon exhaustion of the madia (as indicated by unacceptable hardness leakage),
The regeneration sequence reverses the above process and converts the softener media back to the sodium form for the subsequent water softening cycle.
Capabilities range from 20,000 to 30,000 grains per cubic foot depending upon the total dissolved solids content of the water, the effluent water quality desired and the amount of sodium chloride regenerant used. It should be noted that although the water is softened, the total dissolved solids content remains unchanged.
The installation of a water Water Softener Element will quickly begin paying for itself. Water heaters and boiler will last longer. Costly special chemicals for boilers and steam handling equipment can be greatly reduced. All of the above will experience reduced energy consumption and costly plumbing repairs.
The service life of linens, clothing, fixtures and appliances is noticeably extended.
LOW PRESSURE OR GRAVITY FEED RAINWATER FILTER SYSTEM
The Gravity Feed Rainwater Filter System is ideal for people who don’t have pump pressure on their rainwater supply, the housings are made from UV stabilised material as opposed to the white coloured housings which are not UV stable and not designed to be exposed to sunlight. These housings and filter systems are also ideal for caravaners who encounter low pressure situations, have to have their filter systems exposed to sunlight or need a system that will withstand the rigours of being knocked around while in use.
The system holds a 1 micron pleated polyester element which has the capacity to filter bacteria like Giardia, Cryptosporidium and E Coli from the water without greatly reducing the pressure from the tank.
The filter will filter all the sediment from the water at the same time.
If the pleated filter becomes clogged with sediment it can be removed, rinsed out, placed back in the housing and reused.
These systems are extremely easy to fit and come with 19mm ports which will accept a variety of fittings to suit most applications.
For caravaners these units are available as Twin Filter Housing Systems designed to be fitted with an additional carbon element and resin core to remove the taste and dissolved minerals from water encountered along the road.
Filters should be replaced every 12 months regardless of how often or how much water has flowed through the system.
