Strainer in water treatment is a coarse filter tool that functions to filter large solid particles from the water flow before the water enters the next processing stage.

Here’s a more complete explanation 👇

Strainer Function

Strainer functions to:

• Filter out large solid impurities such as leaves, twigs, coarse sand, plastic, mud, and fibers.
• Protect subsequent equipment such as pumps, valves, fine filters, or membranes from becoming clogged or damaged.
• Maintain the efficiency of the water treatment system, as it prevents pressure drop and mechanical damage to the system.

Working Principle

Water containing impurities is passed through a sieve (mesh or screen) inside the strainer.

• Solid particles will be retained on the surface of the filter.
• Clean water will come out to the next process.
• Strainers need to be cleaned regularly to prevent clogging.

Types of Strainers

1. Basket Strainer
   Used in large pipes; basket-shaped to collect dirt.
   Suitable for large flow systems and easy to remove for cleaning.
2. Y-Strainer
   Shaped like the letter “Y”; commonly used in high pressure piping systems.
   More compact and often used for industrial water or cooling systems.
3. T-Strainer
   Shaped like the letter “T”; usually used in systems that require easy maintenance and high efficiency.

Application in Water Treatment

Strainers are usually installed at:

• The initial stage (intake), before the water enters the pump.
• Before fine filters or main treatment units, such as sand filters or membrane systems.
• In circulation systems, to prevent clogging of components.

Maintenance

• Strainers must be cleaned regularly to avoid a decrease in water discharge.
• In automated systems, self-cleaning strainers can be used which wash themselves using backwash pressure.
