The disclosed technology includes pre-filter system that can include a filter portion comprising pipes, elbows, and tees. The pipes can include apertures. The pipes, elbows, and tees can be positioned such that a first end of a first group of neighboring pipes can be fluidly connected to form a column of fluid connection and a second end of a second group of neighboring pipes can be fluidly connected to form a row of fluid connection. The apertures of at least some of the pipes can be covered with a mesh netting. The pre-filter system can include an airtight float portion. The float portion can be attached to the filter portion to provide a predetermined amount of buoyancy to the pre-filter system.

A floating liquid intake for a liquid suction removal system, the liquid intake comprising housing defining an internal cavity. The housing has a hollow and buoyant annular body, an upper cover and a lower cover. The internal cavity is formed between the upper and lower covers. A substantially annular inlet is formed in the annular body for ingress of liquid into the cavity. The annular body has a buoyancy sufficient for the liquid intake to float in a liquid with the annular inlet submerged below the surface of the liquid in which the liquid intake is floating. A pipe extends into the cavity and the pipe includes an inlet that in use is open below the surface of the liquid within the cavity. The pipe extends outside of the cavity for connection to a liquid suction removal system.

A float assembly that can generate its inflowing water current for collecting water surface debris in a water body. Float assembly can be mounted to a fixed structure at the water body and includes a basket supported by a pair of floats buoyant in water. The basket includes a pump housed in a perforated housing, wherein the pump can be operated to suck water through the inlet also carrying the debris into the basket. The debris of a suitable size can be retained in the basket while the water is pumped out through an outlet. The basket can be switched from an operating state i.e., submerged in water to a stowed state outside the water upon the fixed structure.

A floatable 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.
