Step By Step Guide On How To Soften Hard Water
The hardness of water depends on the presence of two soluble minerals like magnesium and calcium. These minerals have no health effect on the body or health and need for daily nutrients.
These minerals give a refreshing flavor of the water the taste of water becomes significant. If there is no calcium or magnesium in water, there is no residue in the pipes or water heater does not affect the effectiveness of detergents and soaps. So we can say the water is hard water.
Water hardness is analyzed in 1 of 2 units of measurement. The first one is parts per million of calcium carbonate; a word is same to the concentration of mixed calcium and magnesium.
Using this amount simplifies the hardness calculation. 1 ppm means 1 unit of calcium carbonate is mixed with 1 million units of water. The parts per million are same as milligrams or liter.
The next expression of hardness is grain per gallon of calcium carbonate. A gpg is a hardness unit and same as about 17 mg/I or ppm.
If you taste the water of your house, the result will show how hard your water is in your home. As the stages of calcium carbonate indicate little to water consumers, the specialists have classified the levels of hardness, and the below table shows the classification.
Problems caused by hardness in water
As hard water will not unhealthy, it may cause some costly problems. The main issue is scaling that precipitation of the minerals to create rock hard deposit called limescale.
The scale can store inside the pipes and may decrease the life span of toilet units up to 70% and 40% for water taps.
This may store inside coffee or tea pot, clog and ruin the water heater. For home use, it will take more soap and synthetic detergent for washing and laundry. The conditioning water will take half of soap to clean something.
Soap combine and hard water create Soap scum which can not be washed off, creating a bathtub ring on all surfaces and it will dry leaving unsightly spot over the dishes.
While using soap on the body with hard water cause the storage of scum that is known as curd. The curd or scum is the cause of magnesium and insoluble calcium salts available in the soap.
The curd remains on the skin though you wash it well, coating body or clogging pores. They can be used as a medium to grow bacteria and cause minor skin irritation, nappy rash, dry skin and continuous inches.
Though you use the shampoo regularly, there will remain some insoluble salts in hard water that are hard to untangle or remove.
Hard water creates scaling on the cooling towers, boilers, and the other industrial equipment in the industry.
So Water hardness should be monitored to escape from the costly breakdowns. Hardness can be removed by adding chemicals or by great scale softening with zeolite resins. The presence of calcium means hard water.
Types of water hardness
This indicates hardness which effects may be alternated by boiling water in the open container.
Limestone formations percolate this kind of water or contain bicarbonate HCO3- with some amount of carbonate CO32 as the main ions. Boiling water enhances the reaction.
2 HCO3– → CO32– + CO2
By eliminating the carbon dioxide gas. The CO32 does function with Ca2+ Mg2 + ions, to create magnesium carbonates and calcium carbonates that precipitate out. The result is to form soap scum will be reduced significantly.
The water which has sulfate nad chloride and impossible to remove by boiling is called the permanently hard water. The only softness system is to eliminate ions from water, by the method stated below.
How to remove hardness
Adding sodium carbonate
Sodium carbonate or Na2CO3 is known as the washing soda. This can remove permanent or temprary hardness from water. Calcium carbonate and magnesium carbonate is insoluble, but sodium carbonate is soluble.
The carbonate ions of sodium carbonate react with the magnesium and calcium ions in water and make insoluble precipitates. Suppose:
sodium carbonate+calcium ions → calcium carbonate + sodium ions
Ca2+(aq) + Na2CO3(aq) → CaCO3(s) + 2Na+(aq)
The water is softened. As there is no calcium in the water or no magnesium ions. Soap will make lather easily and simply.
However, magnesium carbonate and calcium carbonate are responsible for forming limescale. It may clogs up the pipes you use and may affect the flow of water from your water system.
Sodium carbonate will help to make the water soften for some circumstances like softening water to wash clothes with hand.
Ion exchanges columns
A water softener is used in the ion exchange resins. The substances are made into beads that are packed in cylinders known as ion exchange columns. They can be stored in a machine like dishwashers or plumbed into the water system to soften water.
The resin beds have sodium ions. While the hard water passes through the column, the magnesium and sodium ions swap somewhere in the sodium ions.
Magnesium and calcium ions are stored to the beads, at the time of leaving the column some sodium ions remains with the column.
The hard water turns to soft water as there is no magnesium or calcium with the water. Sodium ions are sometimes used in some ion exchange resins instead fo hydrogen ions.
The resin beads of dishwasher become saturated with magnesium or calcium ions; they can be regenerated with the sodium chloride.
The sodium ions substitute the magnesium and calcium ions on the beads. Sodium Chloride is very cheap and found everywhere, makes it convenient and much cost efficient system.
Shower head water filters
The filter of the shower water is the best method to trap chlorine, lead and unwanted smell from the water of the shower. People now like to use KDF technology in their home to filter the water of the shower.
The KDF system works by ion exchange process to remove contamination. The ion gives and takes process converts contaminants to harmless elements. At the time of this process electrons are transferred among the molecules, and some new components are found.
So the harmful contaminants turn to harmless contaminants. KDF are discovered in some showerhead filters as it can work with high temperature and for the flow of the rate.
Reverse Osmosis (RO)
Reverse Osmosis can work with low temperature, and the energy consumption is very economical, people apply it to various applications, suppose, cleansing of contaminated water, minerals, desalination, regulating per cent of different water filtration and food productions.
Most of the RO system work with cellulose acetate membrane work within 55 to 86 degree F.
Dirty water may pass one or two of the following points: retention volume or chlorinator volume, gasifier, anthracite filter, sand bed, neutralizer, micro filter, activated charcoal filter, deionizer, rely upon the kind of filtered water, the water that gets quality after the filtration process.
How to soften hard water at home
Surely, the long term solution to solve the hard water of your home is to use the water softener, and you may start with arranging a free no obligation house demonstration to suit for you. We will begin as we can, but in the meantime, there are some ways to start with the water softening hard water and reduce the damage or irritation to your house today.
Boil water before use
Boil water first before trying to use it. It will be better to make the water soften before you like to use it for cleaning teeth, cooking food or drinking. Otherwise, they will create more scale on the teeth. If you boil water, you will see impurities or scum over the surface and then scoop them to escape them.
As you keep the water for a longer period, you will see the impurities on the bottom of the pot and you can then able to purr off the softened water.
Use washing soda or lime
A few years back, it was very common that people use lime or washing soda with big storage of water in the barrel or tank to make the water soften.
After few days, impurities and some harsh mineral sediment stored at the bottom and from the top people collected the soft water. Though the method is useful, it takes time. It is difficult to store water in a large pot or needs enough strength to carry the amount.
Add washing soda to water
Hard water does not help soap or detergents to gather lather and does not help cleaning actually. By adding ammonia, washing soda, lye or borax, you can remove the problem for a short time.
The reason is it softens water and resist lime from stopping the lathering system. As the limescale does not remove from water, you will get mineral affecting or durability or dryness of the clothing.
Softening Water for Laundry
Add non-precipitating water conditioner to your laundry. The products trap some of the minerals from water at the time of washing. Be sure the product is non-precipitating. You have to search for online to get it out.
Do not use precipitating conditioner as it may cause scale on washing machine or fabric. Select a product and connect it with laundry as stated below:
- According to the instruction add it with wash cycle. If you have no idea of hard water area, add conditioner up to you get water that feels slippery suds comes during the time of washing.
- Use a 2nd batch of the conditioner at the date of rinsing cycle. If you do not do so, all the mineral will latch on your clothes.
Treat hard water spots with vinegar. Distilled white vinegar can remove white spots over fabric, or mineral, drains, build up. Use dilute or plain with the same amount, scrub the problem and wash well.
This solution is tedious to remove builds up rapidly. If the water is slightly hard, this may be cost efficient system.
- Some people like half cup vinegar to remove cycle in water, though some claim rubber seals of the machine. Think about the checking of your dear machine manufacturer.
- Vinegar may bleach some kinds of damage stoneware of fabrics
- For hard water, a towel can be stiff. Contact with it with the same procedure.
Selecting a Water Softener
Buying a good water softener is the matter now. So some following hits will help you to purchase the bet water softener.
- Consider the price then decide the system and then think about the cost of installation and operation. Water treatment means the expensive units but offers excellent result.
- See the warranty. I believe you understand it. Warranty may be for one year or maybe for a lifetime. Escape the both extremes. A dependable warranty will be for ten years of the tank or five years or on the control valves.
- If you see the price of installation is with the buying receipt be sure you have not paid later for garden water systems, bypassing lawn or replenishing swimming pools and so on.
- Be sure you have understood the system and cost of recharging the method.
- Collect the names of the customers from the dealers. Ask them if the customers are satisfied or not with the equipment or service. You may ask your friend who has invested money in buying the water softener for his or her home.
- At the time of buying any water treatment equipment, such as water softener, look for the seal from Water Quality Association (WQA), or Underwriters Laboratories, Inc. (UL), National Sanitation Foundation (NSF). The seal indicates that the equipment are tested well, and the performance of the system is very excellent
