Sand - Activated carbon filtration

The sand - activated carbon filtration system is a coarse solid filtration technology with a size of 1 - 0.01 mm and the filtration pressure depends on each filtration method such as non-pressure filtration and pressure filtration.

Raw sand filters of 1-2mm, quartz sand and activated carbon are commonly used as filter materials. Filter material size is calculated in detail depending on input parameters.
