The pH of water indicates whether it is acidic or alkaline. The pH scale spans from 0 to 14, with 7 being the neutral point. The pH range of typical drinking water is 6–8.5. The pH is mostly determined by the natural geological conditions at the site and the minerals found in the local rock. Acid rain can also have an impact on pH. Water with a pH value of less than 7 is acidic and caustic. Acidic water (low pH) can leach metals from plumbing systems, causing leaks. Metals that leach from pipes (for example, lead from lead pipes or copper from copper pipes) may potentially create health issues.Water with a score more than 7 shows alkalinity and has a negative impact on the taste of the water. Drinking alkaline water may have a "soda" taste. Corrosion issues can also develop in pipes.
What is a Water Treatment pH Adjuster?
A pH adjuster is a chemical that is used to change the pH or Potential Hydrogen level of a solution. pH (Potential Hydrogen) is a measurement of hydrogen ion activity or how basic or acidic something is. You can lower the pH by adding a pH reagent, such as an acid. You can raise the pH of a solution by using a caustic or another alkaline material.
What chemicals are used to change the pH of a solution?
Sulfuric acid and sodium hydroxide (caustic) are the most often used acid and base neutralizers. When adjusting the pH, employ caution since an exothermic reaction will occur, creating heat.The greater the severity of the application, the greater the amount of heat generated. For example, adjusting the pH of tap water produces very little heat and is therefore unproblematic.
How do neutralizing filter’s function?
If the drinking water is acidic, a neutralizing filter is utilized (low pH). It is a straightforward treatment device that increases the pH of water by introducing a neutralizing substance. It should be noted, however, that the neutralizing procedure may increase the hardness of the water.
Neutralizing filters are point-of-entry devices that elevate the pH of water to neutral levels (about 7), reducing or eliminating plumbing corrosion concerns. Calcium carbonate is used to treat water with a pH more than 6, whereas synthetic magnesium oxide is used to treat water with a pH less than 6.
The filter is filled with limestone or magnesium oxide media and filters untreated water. This substance dissolves in water and elevates its pH level.
All treatment systems need routine maintenance. The material used in a neutralizing filter must be replaced on a regular basis, and the filter must be backwashed.
Installing a cartridge filter before the neutralizing filter removes solid particles from the water and may assist to extend the life of the neutralizing filter.
The main disadvantage of these filters is that if calcium and magnesium are employed in the filter, they may or may not increase or induce water hardness. If hard water becomes a problem, a neutralizing filter should be used first, followed by a water softener. Water hardness may be undesirable for those on a low-sodium diet if it is treated with salt.
Aside from water hardness, neutralizing filters may cause water pressure loss since the water must pass through finely ground neutralizing material.
Because neutralizing filters are usually placed after the pressure tank, neither the pressure tank nor the well pump are protected from corrosion.Whereas if flow rate is large, a liquid injection system may be preferable to a neutralizing filter since it is put before the pressure tank and so protects the tank and the piping system from corrosion.
