Placed as primary treatment in treatment plants, it allows a better yield of the rest of the plant, as well as a smaller operation cost.
These equipments, whose screening fineness is between 0.25 mm and 3.00 mm, are generally used in waste water.
They are also of correct application in industrial waste waters.
Static sieves have an incorporated screen, constituted by horizontal bars in special profile built in stainless steel of Aisi 304 or 316 quality.
Water is distributed in the upper part of the screen, whose inclination over horizontal diminishes progressively from top to bottom between 65 º y 45 º approximately. Effects of separation and dripping of solid matters are obtained successively.
