An F.O.G. separation apparatus includes a tank for receiving a liquid effluent flow containing water, F.O.G., and gross solids. The tank has a chamber, an inlet in an inlet module, a downstream section and an outlet in an outlet module. The inlet module has a weir for the effluent downstream of a strainer to strain gross solids from the effluent. A pump upstream of the strainer pumps water and solids that do not pass through the strainer. The pump's rotatable vertical shaft has a motor at an upper and an impeller at the bottom. A pipe connected to the inlet module near the impeller conveys solids and water when the pump is activated and directs the solids and water to the outlet. F.O.G. and water entering the tank pass to the downstream section where the F.O.G. is removed from the water by a skimmer, and the residual water exist the tank through the outlet module.

The invention relates to a nuclear facility pool cleaning device having a floating platform, capable of floating in water, having buoyancy bodies; a drive device for displacing the floating platform on the surface of a water-filled nuclear facility pool to be cleaned; a winching device connected to the floating platform; a pump which is winchable vertically by the winching device and has a vacuum hose, connected thereto at its first end, for cleaning the bottom of the nuclear facility pool; a remote control device for remotely operating at least the drive device and the winching device; an optional stationary external storage tank; and wherein the second end of the vacuum hose preferably leads at least indirectly into the stationary external storage tank.

A method for removing solids submerged in a polymer-based slurry. The present invention filters used polymer-based slurries, containing solids, to return the slurry to a condition that is favorable to the owner. The method utilizes a first collection tank, an agitator, a shaker with a plurality of screens, a desander, a desilter, a centrifuge that removes solids down to a size range of 5-7 microns, and a second collection tank. Each component can be used in tandem depending on the polymer-based slurry characteristics that are required by the owner. The preferred embodiment includes the following steps: obtaining used polymer-based slurry, pumping the slurry into a first collection tank where the slurry undergoes agitation, pumping the slurry through a plurality of screens, pumping the slurry into a desander and/or a desilter, passing the slurry through a screen, and pumping the slurry in centrifuge that removes solids down to a size range of 5-7 microns. After completion of the method, the owner can decide to repeat the steps to obtain a polymer-based slurry in accordance with their requirements.

The invention relates to a method for clarification of raw green liquor in a sedimentation tank. According to the invention is a part of dregs separated in the sedimentation tank recirculated back into the inflow of raw green liquor, and preferably after passing the dregs through at least one turbulence generator (30, 31) that could break up larger dregs particles into smaller dregs particles, and thus create larger total surface on the dregs particles, improving sedimentation rate in the sedimentation tank. In a preferred embodiment is the recirculated dregs added into the flow of raw green liquor before a flocculant is added into the flow of raw green liquor and mixed recirculated dregs.
