Stainless Plate Settler

Stainless plate settler is a device or separation unit used in water or wastewater treatment processes, mainly to separate suspended solids from liquids by utilizing the force of gravity. The "stainless" component indicates that this tool is made of stainless steel, which is resistant to corrosion and suitable for chemical applications and the food industry.

Here's a more detailed explanation:

Working Principle

Plate settler works on the principle of sedimentation - solid particles will settle due to gravity.
However, to increase efficiency, there are inclined plates that are arranged parallel and tightly.
These plates:

• Shorten the distance the particles have to travel to settle.

• Increase the contact surface area, so that the separation process occurs faster.

• Produces laminar (quiet) flow, so that sediment is not disturbed.

Construction of Stainless Plate Settler

Usually consists of:

• Main tank (basin) where water flows slowly.

• Stainless steel inclined plate, mounted at an angle of about 45-60°.

• Inlet and outlet pipes for raw water and clear water.

• A sludge hopper at the bottom to collect sludge.

Uses and Applications

• Drinking water treatment plant (WTP).

• Industrial wastewater treatment (WWTP).

• Cooling water treatment.

• Chemical and food industries, where hygiene and corrosion resistance are important.

Advantages of Stainless Plate Settler

• Rust resistance and long service life.

• Easy to clean and maintain.

• Compact design (takes up less space than conventional sedimentation tanks).

• High efficiency in separating suspended solids.
