Percolator Filters
Trickling filters are a type of wastewater treatment technology used in the secondary treatment stage. Trickling filters are used to remove organic and inorganic contaminants dissolved in wastewater through a biological filtration process.
The trickling filter consists of a bed of granular material, such as gravel or stone, that is placed in a tank. The wastewater is sprayed onto the bed of material, which acts as a support for a layer of bacteria and other beneficial microorganisms. These microorganisms break down the organic contaminants present in the wastewater and convert them into solid materials that can be more easily removed in the tertiary treatment stage.
The filtration process of trickling filters is aerobic, meaning it requires oxygen. Therefore, the waste water is sprayed on the material bed with a certain amount of air to provide oxygen to the microorganisms that decompose the contaminants. Trickling filters are effective in treating wastewater with a relatively low organic load.
They are also an economical, low-maintenance solution for wastewater treatment in small communities and rural areas.
Pressure Pull Flow Distributors
Pressure traction flow distributors require a constant pressure, from the water outlet it generates an ejection force that allows the equipment to rotate. The purpose of the distribution equipment is to distribute the incoming flow over the trickling filter for its efficient work.
Center Pull Flow Distributors
Central traction flow distributors are optimal for large tanks and variable flow rates, they rotate through a central pinion system.
Plastic filling
Trickling filters require a special filler that functions as a bacterial bed. Equom with our ally Biolam offers this type of filler.
