The water to be filtrated is introduced in the lower area of the sand filter through a special designed cone that distributes evenly the inlet water into the sand bed made of quartzitic sand. The water, flowing through the sand bed, settles the solid particles contained and conveys to the upper part of the filter where is discharged by an overflow. The contaminated sand is pumped to the washing device where is continuously washed using a small fraction of already filtrated water, that is then collected to a separate outlet. The cleaned sand is again replaced at the top of the bed.
