Nowadays, the emergence of large-flow water filter elements has solved many water filtration and water treatment problems, so how is the technology of large-flow water filter elements realized?

The factors and principles of large flow water filter to achieve large flow are as follows:

The large-flow water filter element is the core filter unit of the large-flow filtration system. It adopts horizontal pleating technology and uses precision pleating technology. The corrugation is uniform and the area of the filter medium is larger in a limited space. The design pressure of the large-flow filter element is 80 cubic meters. The actual pressure flow depends on the actual working conditions.

Filtration process and working principle of large flow filter element

When the liquid to be filtered passes through the high-flow filter element, the water in the inlet pipe enters the filter through the drainage channel, then passes through the support layer from top to bottom, is collected by the water distribution system, and is discharged through the outlet pipe.

After filtering for a period of time, the amount of suspended matter remaining in the filter layer increases, and the porosity of the filter layer decreases, thereby increasing the flow of pore water.

On the one hand, the filtration resistance increases, on the other hand, the impurities in the pores are washed away by the water flow, the pressure increases, and the water quality deteriorates. When the head loss exceeds the allowable value, or when the concentration of suspended solids in the effluent exceeds the specified value, the filtration and backwashing of the filter should be terminated.
