Centrifugal water filtration

The hydrocyclone is a physical and mechanical separation device used to remove suspended solids from water without using filters or moving parts. It operates based on the centrifugal force generated by a spiraling water flow.

How It Works:

1. Tangential Inlet: The water enters tangentially, creating a rotational flow inside the conical chamber.

2. Density-Based Separation: Centrifugal force pushes heavier particles toward the outer walls, moving them downward in a spiral.

3. Solids Discharge: These particles are collected and discharged through the bottom outlet (also called purge or underflow).

4. Clean Water Outlet: The cleaner water rises through the center and exits from the top of the unit.

Advantages in Water Treatment:

• No moving parts: minimal maintenance, high reliability.

• Effective removal of sand, sludge, mineral or organic particles.

• Reduces load on secondary filters (e.g., sand or mechanical filters).

• Easy to install, low operating cost.

• Continuous operation without flow interruption.

Use in Aquaculture:

• Pre-treatment in RAS (Recirculating Aquaculture Systems) to reduce solids before biofiltration.

• Protects downstream equipment (UV sterilizers, pumps, biofilters).

• Ideal for separating fine particles like waste, uneaten feed, or sediments.
