What does a Dealkalizer do?
A dealkalizer works similar to a water softener, in that it utilizes ion exchange to remove unwanted ions from a water supply. However, rather than removing calcium and magnesium ions, dealkalization removes carbonate ions, exchanging them for chloride ions.
What is the alkalinity of water?
The alkalinity of water is a measure of how much acid it can neutralize. If any changes are made to the water that could raise or lower the pH value, alkalinity acts as a buffer, protecting the water and its life forms from sudden shifts in pH value.
What is the unit of alkalinity?
The unit of measurement for alkalinity is mg/L CaC03. What is the significance of alkalinity? Alkalinity is the measure of the resistance of water to the lowering of pH when acids are added to the water.
How do you remove alkalinity from well water?
The feed of a mineral acid will neutralize the alkalinity of water. Hydrochloric acid, sulfuric acid or a combination of these can be used. This process converts the bicarbonates and carbonates present into carbonic acid.
What does a Dealkalizer remove?
The dealkalization of water refers to the removal of alkalinity ions from water. Chloride cycle anion ion-exchange dealkalizers remove alkalinity from water. Chloride cycle dealkalizers operate similar to sodium cycle cation water softeners.
Does softening reduce alkalinity?
Disadvantages: While water softeners are good at removing hardness, they do not reduce the mineral content of the water; nor do they remove silica or alkalinity.
What is the normal range of alkalinity?
Total alkalinity is measured by its concentration in parts-per-million (ppm), and the ideal range is from 80-120 ppm, depending on the type of chlorine you use.
Does water softener reduce alkalinity?
Disadvantages: While water softeners are good at removing hardness, they do not reduce the mineral content of the water; nor do they remove silica or alkalinity. For some boiler systems, reducing these compounds is required.
What causes high alkalinity in water?
Causes of High pH Levels in Water In short, environmental factors are the biggest contributor to water pH, whether high or low. When it comes to increasing drinking water alkalinity, various chemicals and pollutants are known to cause high pH levels.
Does TDS affect alkalinity?
At low levels, TDS does not present a problem. In fact, a certain amount of TDS is necessary for water balance. Hardness and Total Alkalinity are both part of TDS.
What does the term dealkalization of water mean?
The dealkalization of water refers to the removal of alkalinity ions from water. Chloride cycle anion ion exchange dealkalizers remove alkalinity from water.
Why do you need a dealkalizer for a cooling system?
Cooling system make-up will also benefit from reduced alkalinity. The addition of a dealkalizer to a cooling water system will substantially reduce the amount of acid required to treat the same amount of water.
What should the alkalinity be in a dealkalizer?
In order to justify installation of a dealkalizer on low-pressure boilers, the alkalinity content should be above 50 ppm with the amount of make-up water exceeding 1,000 gallons (approx. 4,000 litres) per day. Cooling system make-up will also benefit from reduced alkalinity.
How does a dealkalizer work like a water softener?
Like water softeners, dealkalizers contain ion exchange resins that are regenerated with a concentrated salt (brine) solution – NaCl. In the case of a water softener, the cation exchange resin is exchanging sodium (the Na + ion of NaCl) for hardness minerals such as calcium and magnesium.
