Question

Treatment for PH to obtain it in acceptable limit.

Answer 1

Explanation:

Two major solutions:

Solution 1: Install a neutralizing filter containing calcium or magnesium minerals to raise pH. As water passes through the filter, it absorbs some of these minerals. Water with extra calcium or magnesium is called ‘hard’. A neutralizing filter requires care.

• It must be backwashed from time to time to remove solid particles from the water. [Some experts recommend installing a cartridge filter first, to remove solid particles.
• The calcium or magnesium (sometimes called the neutralizing material or resin) must be replaced from time to time. Test your water after installing a neutralizing filter.
• Remember, the neutralizing filter will add calcium or magnesium to your water. Levels up to about 120 milligrams per liter (120 mg/L) are fine.
• If levels of calcium and magnesium are higher than 120 mg/L, your water is ‘hard’. You may want to install a second treatment system to ‘soften’ the water. Ion exchange treatment can be used.

Solution 2: Feed a solution of soda ash to the water supply with a chemical feed pump. Soda ash (sodium carbonate), also called washing soda, can be used in a treatment system to raise pH:

• To neutralize larger volumes of water
• To disinfect the water at the same time, since bleach and soda ash may be mixed in a single solution and fed into the water system with the same pump unit.
