Waste Water Softening: Process and Methods in RO System
Water Softening System is a Solution!
A water softening system is the solution for you if you're largely concerned about how hard water affects your skin, clothes, and appliances. A water softener will keep the limescale build-up that stains your sinks, toilets, and appliances at bay. Hard minerals, such as calcium and magnesium, can corrode your pipes over time, as well as your hair and skin. Your shampoos and soaps will function better, your dishes, shower doors, and sink fixtures will be brighter, shinier, and spot-free, and radiation will be removed from your water with a decent water softener. Softer water also acts as a natural exfoliant, which can help to reduce the appearance of skin diseases like psoriasisand eczema.
Natural groundwater (from bore wells, tube wells, hand pumps, and wells) is often hard. This is due to the fact that water is a universal solvent that collects minerals (Calcium and Magnesium) when it passes through the earth's crust and beneath the ground.
Process Involved
A water softener uses an ion exchange mechanism to remove hardness (a combination of Calcium and Magnesium salts) from the water. Hard water is defined as water with high levels of dissolved minerals such as magnesium and calcium (between 120-180 PPM). Several cubic feet of porous plastic resin are covered with molecules that attract and bind to positive ions dissolved in water in the unit. Sodium positive ions normally coat the resin, but as water runs over it on its way to your sink or washer, the naturally occurring calcium and magnesium positive ions found in hard water adhere to the resin.
To keep the electrical charge on the resin balanced, sodium ions are released into the water. The resin becomes saturated with calcium and magnesium ions as the majority of the sodium ions are discharged into the household water. The unit must renew the resin every few days by rinsing it with a concentrated saltwater (sodium chloride) solution, generally in the middle of the night.The high concentration of sodium ions in the salty water displaces the calcium and magnesium ions from the resin, allowing sodium ions to cover it once more. The calcium and magnesium ions in the salty rinse water are flushed down the drain, and the system returns to normal operation. (To prepare this salty rinse water, add a bag of sodium chloride salt to the softening unit every now and then).
The Water Quality Association defines hardness as 10 grains per gallon hardness, and each cubic foot of resin may efficiently remove calcium and magnesium from around 3,200 gallons of hard water. The technique adds roughly 750 mg of salt to each gallon of water, which is considered "low sodium" by the US Food and Drug Administration for commercially produced beverages. Resins that release potassium into the water are available for persons who are concerned about their overall sodium intake, however the potassium chloride salt used to renew the resin every few days is more expensive than conventional sodium chloride salt.
Following a suitable and best procedure known to soften the water, Netsol’s water purifier provide safe water with all the hardness removed and up to the mark of standards.
