Traveling water screens including a non-metallic seal plate mounted to a face of a carrier chain link proximate a side portion of a basket frame are disclosed. The seal plate is configured to reduce flow between the chain link and the basket. Related methods of retrofitting a traveling water screen are also disclosed.

A brine injection machine for injecting brine to meat pieces is provided. The machine comprises an auxiliary frame (10) configured to carry a pre-filtering unit (6), and a pre-filtered brine tank (7), the auxiliary frame being detachable with regard to the main frame (1). At least one level sensors (32) is configured for detecting an amount of pre-filtered brine in the pre-filtered brine tank (7), and an electronic control device is configured for controlling the brine injection operation as a function of the amount of pre-filtered brine in the pre-filtered brine tank (7) that can be recycled, as detected by the at least one level sensor (32) at the end of a brine injection cycle. It is also disclosed a method for operating a brine injection machine according to the invention.

Cleanup and recovery equipment for removing a biological contaminant from a body of water, and a vessel containing same, the equipment including an intake end, a second end, two vertical walls, and a filtering material extending between the vertical walls and having outer side portions of the that press against and create a seal with lower inner surface portions of the two vertical walls and extending from the intake end to the second end such. When activated on a forward-moving vessel, the filtering material separates the biological contaminant from the body of water as water and biological contaminant from the body of water is forced upward and between the two vertical walls and over the filtering material, using water pressure resulting from the motion of the vessel and the weight of the upwardly forced water. The filtering material transports the biological contaminant toward the second end.

An apparatus includes a materials separator that includes a continuous filter belt disposed around a plurality of rollers. The apparatus also includes a pressure differential system operatively coupled to the separator and configured to adjust a pressure differential across the continuous filter belt. A vacuum is applied to the continuous filter belt and a fluid portion of the slurry on the continuous filter belt is drawn through the continuous filter belt. An apparatus includes a materials separator having a first deck with a first continuous filter belt and a second deck with a second continuous filter belt.
