Sand Trap System - Brochure

IT IS USED TO SCREEN AND WASH SAND PRESENT IN WATER. WATER FLOWS INTO A CONCRETE CIRCULAR TANK WITH A CONE-SHAPED BOTTOM WHERE SOME ROTATING PADDLES TAKE CONTINUOUSLY IN MOVEMENT THE SEWAGE. THE PARTICULAR MOVEMENT INDUCED BY THE MECHANICAL ACTION OF PADDLES, CAUSE A SECONDARY TRASVERSAL CURRENT THAT, MEETING THE MAIN CURRENT OF SEWAGE, HELPS THE CONCENTRATION OF SAND IN THE FLOWS OUT FROM THE EXIT, OPPOSITE TO THE ENTRY, SITUATED IN THE TOP SIDE OF TANK.
