Sand Filter
In tilapia farming, pollution parameters in the water such as silica, residue, turbidity, slippery material in water are indicative of polluted water, and the water needs to be cleaned with various filtration methods for the health of tilapia. Sand filter is one of these. Among these pollutants, those having a given diameter are treated with physical residual filtration units. Many pollutants in the water cannot be removed by direct filtration. These pollutants are usually oxidized or softened with some chemicals and then taken to the filters.
