Abstract: A method is provided for filtering a fluid. The method includes the step of selecting a first surface filtration medium to include layers of a first mesh material (FMM). The method also includes the step of selecting a second surface filtration medium to include layers of a second mesh material (SMM). The layers of FMM are selected to include a first number of layers (FNL) for collectively providing a first absolute micron filter rating (FAMFR) and a first capacity for collecting a first type of particles. The layers of SMM are selected to include a second number of layers (SNL) different from the FNL. The SNL is selected for collectively providing a second absolute micron filter rating (SAMFR). The SAMFR is different from the FAMFR. The SNL is also selected for providing a second capacity for collecting a second type of particles. The second capacity is different from the first capacity.

Abstract: A filter bag for use in a liquid filtering system is provided. The filter bag comprises a filtration layer. The filtration layer is defined by one or more filter mediums. The filter mediums can be composed of an adsorbent material disposed between two thin wall substrates. The adsorbent material can be a granular activated carbon. The thin wall substrates can be selected to be highly porous thin wall substrates. The filter bag can further comprise one or more diffusion mediums. The diffusion mediums can be defined by a woven or a non-woven mesh material. The mesh material can be selected from a suitable material that is temperature and fluid compatible with the filtering application to be carried out. The filter bag can include alternating layers of medium having one or more filter mediums and one or more diffusion mediums.

Abstract: A washing station and method for removing debris and oil from landscape maintenance equipment vehicles includes a self-contained pressurized washing system that separates the washing water from solids, washes the solids, captures the oil and debris, recycles the filtered water and prevents contamination of the surrounding area.

Abstract: A seamless filter bag with integral sealing means for use in a filter housing utilizing a filter basket includes an integral sealing means, which is part of a semi-rigid ring member affixed to a filter bag. Upon closing the filter housing cover a complete seal circumscribing the filter basket and filter housing cover is provided.

Abstract: A seamless filter bag having a removable, reusable ring includes a heat sealed filter bag open on one end adapted to receive a removable ring therein. Openings are provided in the filter bag which receive inwardly extending protrusions on the ring thereby maintaining the integrity of the filter bag material. A handle adapted to be received by the inwardly extending protrusions on the filter ring permits the removal of the filter bag together with the ring and any material retained in the bag from a conventional filter basket.
