Alum is a chemical coagulant that is frequently used in water treatment operations, and alum dosing tanks are containers or tanks used to store and dispense alum. In order to facilitate the removal of particles and pollutants by filtration or sedimentation, alum is frequently added to water as a coagulant. The size and capacity of the tanks can change based on the particular application and the required amount of alum. Indicators for level, mixers, and dosing pumps are frequently included in these tanks to guarantee precise and reliable dosing of alum into the water.

Why Use Alum Dosing Tanks? 

In order to make it easier to add alum to the water being treated, alum dosing tanks are utilised in water treatment procedures. In order to remove pollutants from water such as suspended particles, colloids, and organic matter alum is frequently utilised. By incorporating alum into the water, it creates a gooey substance that attracts and bonds with these pollutants, making them simpler to filter out or sediment.

Using this type of tank has several benefits, including:

Consistency – The dosing tanks make certain that the right amount of alum is consistently fed to the water, which aids in optimising the coagulation process.

Efficiency – They are made to ensure that the alum is added to the water in the most efficient manner possible, minimising waste.

Safety – These tanks are normally built with safety precautions to avoid chemical spills or leaks, which could be dangerous to both the environment and human health.

Cost-effective – By using an alum tank, water treatment facilities may optimise chemical consumption and minimise chemical waste, which will eventually lead to cost savings.

What Are They Made From

The volume of alum to be stored, the level of chemical resistance necessary, the required temperature and pressure, and the cost all have a role in the material choice for an alum dosing tank. To reduce the danger of leaks or other problems and to make sure the tank’s material is compatible with the chemicals being held, it should be carefully chosen. It is worth noting that Alum tanks that have steel with rubber lining have a record of failure so generally something like HDPE is ideal.
