    Abstract: The invention relates to a method for washing a filter (F) having at least two layers of filtering media (4, 5) for raw water containing components having a tendency to form cakes (M), in particular for seawater, the layers of filtering media being supported by a base (6) comprising pass-through openings and provided with nozzles (6a) enabling air and/or wash water to be injected, the raw water flowing through the layers from top to bottom and the treated water being recovered at the lower portion of the filter, and which comprises at least one spillway (D) at the upper portion thereof for collecting the wash water. The method includes the following series of steps: a) the raw water intake (2) is closed, followed by the filtration outlet valve (13), the filter is depressurized, and the filter cake is broken; b) the water level in the filter is lowered; c) only pressurized air is blown into the lower portion of the filter, said air passing through the layers of the filter from bottom to top and causing the cakes to be reduced to particles, in particular by means of friction; d) rinsing is carried out from bottom to top using only water, the water rinsing time being sufficiently short to ensure that the water level stops below the level of the upper edge of the wash water collection spillway; e) the filter water is emptied once again by discharging same from the lower portion of the filter; f) steps c), d) and e) are repeated at least once, and a final rinsing is carried out by injecting a quantity of backwashing water through the bottom portion of the filter, which is then discharged from the upper portion of the filter via a pipe (14).

    Abstract: The present invention discloses a system and method for self-cleaning filters without having to open the filter housing. Wash nozzles are integrated with the filter housings such that when the filters are clogged, both back-wash and regular washing can be performed with practically no down time. Moreover, without opening the filter housing, the hazardous components of the fluid to be filtered can be contained and dealt with before they escape the filter housing, thereby significantly reduces the environmental impact and harm to the working crew.

    Abstract: There is described is a belt cleaning blow-off device having a streamlined inner surface. In one embodiment a fluid outlet nozzle is connectable to a conduit of a blow-off device for cleaning a belt filter. The nozzle comprises a housing having an inner surface and outer surface, wherein the inner surface defines a fluid entry zone to receive fluid into the nozzle and an elongated gap for directing fluid towards the belt. The inner surface is streamlined to facilitate flow of the fluid into the gap. In a second embodiment, the blow-off device comprises a housing connectable to a fluid source and having an inner and outer surface. The housing defines a conduit for transporting the fluid within a channel, wherein the inner surface defines a surface of the channel and an elongated gap for directing the fluid towards the belt. The inner surface is streamlined and typically teardrop-shaped to facilitate flow of the fluid into the gap.
