What is strainer in water treatment?


In water treatment, a strainer is a device or equipment used to remove solid particles from water or other liquids. It is a type of filtration system designed to capture and retain larger debris and particles that may be present in the water supply. Strainers are commonly used in various stages of water treatment processes, including pre-treatment, industrial processes, and residential applications.


The primary purpose of a strainer is to protect downstream equipment and systems from damage caused by solid particles. By trapping larger particles, such as sediment, debris, or suspended solids, the strainer prevents them from entering pumps, pipes, valves, and other sensitive components that could be clogged or damaged. Strainers play a vital role in maintaining the efficiency and longevity of water treatment systems by ensuring the smooth flow of water and protecting equipment from potential blockages or malfunctions.


Strainers come in different designs and sizes, but they typically consist of a perforated or mesh screen that captures solid particles while allowing water to pass through. The size of the strainer openings or mesh determines the maximum particle size that can be retained. Some strainers also have a removable or cleanable element, making it easier to clean or replace the trapped particles when necessary.


Overall, strainers serve as a preliminary filtration step in water treatment processes, ensuring that water is free from larger contaminants before undergoing further treatment or distribution.
