ABSTRACT:
The main feature of this invention is a water filter, made up of a top cover, multiple layers of filtration containers (with net board at the bottom of each container) piled up unit by unit, an axle double-deck sleeve (with vents made on edges of the sleeve linking to one of the middle filtration containers) set in the middle to link all of the filtration containers and a pedestal, installed under all the other units, that has a control valve with five square vents to allow the control the direction of water current, to go from the water inlet to internal sleeve and top cover, spread out and flow down from all layers of filtration containers, and the exhausted from the water outlet, after accumulation in the pedestal, to perform a direct filtration. The control valve can also be adjusted to make the water current to come in through the water inlet, go up to the middle filtration container through the external sleeve, spring up to the top filtration container, accumulate in the internal sleeve and flow down to the water outlet to perform a semi-reverse washing. The other feature of this water filter is the function of performing reverse operation of the water current.
