Success parameters in filtration

Filtration is the process by which suspended solids are separated from water.

The quantity and transparency of the water to be filtered will be decisive for the success of the process.

In “standard” water the particle concentration in % of the total weight is inversely proportional to the size. The lower degree of filtration, the higher concentration of solids to be retained. In continental water, of whatever origin, which is properly decanted, the percentage of solids greater than 100 microns will always be less than 20% of the total. In that water with a cut to 20 microns we can retain 60% of the total.

The transparency of the water is going to be an indicator of the aptitude of the water to be filtered.

For the same amount of SS we will retain more of water with greater transparency than another that is not so much. It is reasonable to think that if the water is more transparent, the SS are forming corpuscles of greater size and consistency and therefore, they will be easily retained.

Other parameters such as speed will also have great importance, because in most cases what we retain are not solid objects of a certain size, but organic matter or flocs that deform when passing through a hole if the speed or difference pressure between the chambers before and after the filter medium is greater than necessary.

All information available about water: origin, type of dirt, object of filtration, etc., is important to be able to anticipate the result and correct possible deviations from the process.

The technology of Novhidro allows the filtering surface to be several times greater than that of its competitors and, therefore, the filtration speed is lower.

However, we recommend contacting our technical service to advise and establish an appropriate process.
