A floating suction head assembly for use with a hose, for drawing liquid into the hose. The assembly includes a float assembly, a gusset member coupled to the float assembly and a strainer assembly rotatably mounted to the gusset member. The strainer assembly has a coupling portion for coupling to a hose. The strainer assembly is rotatable relative to the gusset member and the float assembly about a central longitudinal axis defined by the strainer assembly. The strainer assembly includes a strainer cage defining an interior cavity, and a strainer cartridge selectively disposable in the interior cavity and retained therein. The strainer cartridge has a generally cylindrical configuration and rotates about the central longitudinal axis of the strainer assembly. The strainer cartridge includes a corrugated exterior surface including bent portions forming alternating furrow and ridge portions substantially about the circumference of the strainer cartridge.

A floatable, portable and readily deployable apparatus used in a surface water body for the collection, mixing, separation, containment and removal of total solids from fluid in surface water by settling, sorption, floatation or filtration of total solids from fluid entering or pumped into the apparatus. Separation of total solids from fluid can include the use and recycling of commercially available or proprietary biologic, chemical and/or physical substances and processes to increase the rate and percentage of total solids removed from fluid in the apparatus.

A flotation filter has an outer member that has a top section and bottom section that are hollow. The top section has an inner edge and an outer edge with the outer edge having a diameter that is adapted to slide up and down an inner diameter of a storage container. Connected to the inner edge of the outer member is an internal grid. The internal grid includes members that crisscross to provide spaced openings. Further, the internal grid dwells in a plane below a horizontal plane of a top surface of the top section.

A floating filtering apparatus is used to separate solid material in a slurry by size, so that the filtered slurry and/or solid material that has been separated from the slurry can be further processed. The floating filtering apparatus comprises a filtering assembly, a first submergible tank, a first pump, and a receptacle for secondary material. The floating filtering system is contained in or supported by a vessel that floats on water and can move and/or be moved about on the surface of the water.

Described herein is a method for cleaning an electrocoating bath in a continuous facility, where a skid connected to a conveying installation is conveyed through the electrocoating bath, and where the skid includes a filter medium; the filter medium is secured on the skid via at least one movable connecting element; the movable connecting element allows the orientation of the filter medium at the interface between electrocoating bath and air; and, after immersion of the skid into the electrocoating bath, during the conveying of the skid through the electrocoating bath, the filter medium is oriented at the interface between electrocoating bath and air and is drawn along the surface of the electrocoating bath. Also described herein is a skid for use in the cleaning method.
