Correct pH balance is a key factor in many processes. pH plays a very significant role in everyday life from affecting blood composition in the human body, to regulating plant growth, and governing the application of paint. Many water treatment processes are pH dependent. Processes like effectiveness of chlorination, formation of chloramines, floc formation in coagulation processes, corrosion of metal equipment and piping are heavily depend on water pH. Moreover, pH of water determines efficiency of iron and manganese removal.
We recommend to use pH correction as a first step in a water treatment sequence, because it will influence further chemical reactions. We can help to verify pH levels in raw and treated water. Our water quality assessment services can determine the type and quantity of pH correction additives required.
Above all, pH correction products are available through Osorno Store in 1 litre bottles, 20 litre delcans or 208 litre drums.
pH increasing agents are mainly used in water treatment plants. Sodium hydroxide is the most valuable correction additive for raising pH. In addition, another pH correction chemical often used at water plants is sodium carbonate (soda ash). However, soda ash is recommended for use in applications when water alkalinity increase is required.
Therefore, some examples of sodium hydroxide use include:
We suggest to use sodium hydroxide over using soda ash when main focus is pH increase. Sodium hydroxide has twice the capacity to increase pH then soda ash. Another words, for a given pH correction, the sodium content will increase only by half, which is a very important consideration for people concerned with high sodium content in food and water. There are only a particular applications where soda ash is required.
Hydrochloric acid is recommended for decrease of pH in swimming pools and water treatment plants.
