ABSTRACT:
A filter medium is provide in a tubular structure configured in the form of a closed loop. Filter maintenance structures mounted on a continuous string lying within the lumen of the tubular structure are continually driven over the surface of a filter medium to maintain an optimum condition of the filter surface. This string with attached filter maintenance structures is driven around the loop of the tubular structure by hydraulic forces generated by the fluid introduced into the apparatus for filtering.
