In this case, many suspended solids of high size and colloidal solids, silt etc. can be contained.
The most suitable filter in these cases is the ABV filter (200 ÷ 100µm) which combines the cleaning system with brushes for large solids with suction pads for the finer material deposited on the filter tissue.
Depending on the type of sea intake work, it is advisable to use upstream of the UF system:
to. AVC filter for medium-low SST content at size <1mm;
b. ABV filter for high SST content even of large dimensions.
