A method of and an arrangement for thickening of suspensions includes filtering of a suspension through candlelike filter elements in a filter container, backwashing the filter elements individually without interrupting the filtration process by applying pressure impulses of gaseous backwash medium to the pressure elements in a direction opposite to the filtration direction, wherein the gaseous backwash medium forms a gas chamber over the filter elements separated from the suspension fluid and having an adjustable pressure. |
