Gravel Filters

APPLICATIONS 
Provide high quality filtration solutions for water with a high contamination of organic material and algae.

 

STANDARD CHARACTERISTICS
Filter housing material of construction: Carbon Steel ST37.2

Pre-treatment: sand blasting up to Sa 2.5 grade

Two layered coating process consisting of a one primary coating Rich Zinc (60 - 70µm thickness) and a final protective coating of Phenolic Epoxy (70 - 80µm thickness)

Connections: VIC, Threaded socket and Flange

Maximum recommended working pressure: 10 bars (145 psi)

Equipped with “mushroom“ diffusers with vertical openings

Diffusion protection for screws, nuts and washers

 

OPERATION
Water enters the filter via the inlet and spreads evenly onto the media. Solids and organic materials are trapped within the media. The clean water passes through the media and flows out via the nozzles. The back flushing process is done by shutting the inlet of the filter and allowing the water to enter from the bottom, lifting the media and releasing the solids that exit the filter through the back flush manifold. This process can be controlled automatically.
