Agitators in water treatment are devices used to mix liquids in large capacity containers, with the aim of promoting the homogenization of chemical solutions and the suspension of suspended particles during the water treatment process. They are used in steps such as coagulation, flocculation and disinfection. Industrial agitators are designed to meet the specifications of the water treatment process, ensuring treatment efficiency and quality.
Agitators in water treatment work by mixing and agitating the liquids present in the containers. The working process usually follows these steps:
- Chemical Addition: Chemicals needed for the water treatment process, such as coagulants, flocculants, and disinfectants, are added to the liquid in the container.
- Start of agitation: the agitator is turned on and starts to mix the liquids and chemicals, promoting the homogenization of the solution.
- Flocculation: the agitation of the agitator creates a centrifugal force that helps to form flocs of impurities, which coalesce and fall to the bottom of the container.
- Decantation: the flocs formed during flocculation are removed from the vessel by decanting.
- Disinfection: disinfected liquids are released to the next step of the water treatment process.
It is important to highlight that the operating processes may vary according to the type of water treatment being carried out, and the types of agitators may vary according to the needs of each stage of the process.
Agitators in water treatment bring several benefits, including:
- Efficiency in the treatment: the agitation promoted by the agitators helps to guarantee the homogenization of the chemical solution and the suspension of particles in suspension, which increases the efficiency in the water treatment.
- Improvement in water quality: the mixing and agitation promoted by the agitators helps to remove impurities and other contaminants from the water, improving the quality of the treated water.
- Resource Saving: Agitators can be designed to run more efficiently, reducing energy consumption and other resources.
- Flexibility: They can be designed to meet the specifications of the water treatment process, ensuring treatment efficiency and quality.
- Easy Maintenance: Some types of shakers are designed to be easy to maintain, which can help reduce maintenance costs in the long run.
Agitators in water treatment are widely used in various steps of the water treatment process, including:
- Coagulation: agitators are used to mix coagulants with water, promoting the formation of impurity flakes.
- Flocculation: they are used to mix the flocculants with water and the flakes formed in the coagulation stage, promoting the agglutination of impurities.
- Disinfection: they are used to mix disinfectants with water, promoting the elimination of microorganisms.
- Decantation: they are used to mix the water and the formed flakes, promoting the separation of the flakes from the clean liquid.
- Clarification: agitators are used to mix the water and the formed flakes, promoting the separation of the flakes from the clean liquid.
- Filtration: agitators are used to mix the water and the formed flakes, promoting the separation of the flakes from the clean liquid before the filtration step.
These are just some of the applications for agitators in water treatment, and there are many other steps where agitators can be used.
