The acidity or alkalinity of water is referred to as its pH level. In general, water with a low pH (< 6.5) could be acidic, soft, and corrosive. Therefore, the water could leach metal ions such as iron, manganese, copper, lead, and zinc from the aquifer, plumbing fixtures, and piping. Water with a low pH could contain elevated levels of toxic metals, cause premature damage to metal piping, and have associated aesthetic problems such as a metallic or sour taste, staining of laundry, and the characteristic “blue-green” staining of sinks and drains.
The primary way to treat the problem of low pH water is with the use of a neutralizer. The neutralizer feeds a solution into the water to prevent the water from reacting with the house plumbing or contributing to electrolytic corrosion.
The Water Shed uses two methods to adjust the acidity of drinking water:
Chemical Injection Pump
For very acidic water, The Water Shed uses the time-tested Stenner™ which neutralizes pH using caustic soda injections. Their design is renowned for exceptional reliability and ease of service, which increases dependability for users while reducing service time and expense. The peristaltic pumping action makes Stenner™ chemical feeders completely self-priming against pressures up to 100psi. In addition, Stenner™ quality workmanship produces pumps that are durable and accurate to 2% at all settings.
Calcite media is a crushed and screened white marble material which can inexpensively be used to neutralize acidic or low pH waters to a neutral non-corrosive affluent. Acidic waters in contact with calcite slowly dissolve the calcium carbonate media to raise the pH which reduces the potential leaching of copper, lead, and other metals found in typical plumbing systems. Periodic backwashing will prevent packing and maintain high service rates. Depending on pH and service flow, media has to be periodically topped up as the calcite media is depleted.
