Alkalinity refers to the total amount of substances contained in water that can neutralize and react with strong acids. In natural water, alkalinity is mainly based on carbonate and bicarbonate. Alkalinity plays a very important role in the production of fish and shrimp in ponds, and the appropriate alkalinity can stabilize the pH value in the water body, thereby improving the buffer of the pond water body and maintaining the stability of the environment! Of course, if the alkalinity is too high, it will cause poisoning of fish and shrimp, and too low will make water difficult, so the right amount will do! Therefore, it is very important to monitor the “alkalinity” water quality at any time, observe the changes in the alkalinity of the pond water, and conduct reasonable regulation according to the pond environment to ensure the safety of the aquaculture water quality!

What are the Main Sources of Water Alkalinity?

From the perspective of water chemistry, alkalinity is a quantity that reflects the ability of water to bind protons, that is, the neutralization ability of hydrating strong acids, and various substances that can bind protons together form alkalinity. The alkalinity of natural water body mainly comes from the dissolution of carbonate in the rocks and soil in the rainwater collection area, the dissolution and transformation of carbon dioxide in the atmosphere, the decomposition of organic matter and so on.

What Instruments are Used to Monitor Alkalinity in Water?

The TOH-8000 online water quality alkalinity analyzer adopts the continuous flow analysis technology to complete the colorimetric analysis of the sample, measure the absorbance value after mixing the sample and the alkalinity indicator at the specified wavelength, and calculate the actual alkalinity content of the water by comparing it with the standard known alkalinity material. The instrument can monitor the total alkalinity content of industrial boiler water, circulating water and drinking water online.
