A sand-manure liquid separation plant including a tank for the processing of a mixture of sand and manure liquid. The tank including a top portion having a mixture inlet for filling the mixture to be processed into the tank and a bottom portion having a sand discharge for discharging sand settled in the tank. A maximum level (ML) of filling of the mixture is defined within the tank, wherein the mixture inlet is arranged at a position at a level above the maximum level (ML) of filling. The plant further includes a number of fluid outlet(s) connectable to a source of a fluid and arranged above the maximum level (ML) of filling. The fluid outlets being configured to provide a flow of the fluid directed towards the maximum level (ML), below the position of the mixture inlet.

A separator system and method may provide a four-way separator that may separate a material and remove a hazardous material. The hazardous material may include gas and sand that may be removed by the four-way separator. The separator system and method may further provide a main unit that may include three chambers or recirculation hoppers, an auger sand extractor, and a strap tank. The separator system and method may provide a faster rig-up time and may be exclusively driven by hydraulics.

A waste oil handling apparatus features a tank with draining compartments for receiving waste oil containers in inverted and elevated positions above the tank floor. Multiple drain ports communicate with the tank interior at different elevations relative to the floor for draining accumulated contents of varying density that have gravitationally separated into distinct layers at those elevations. The ports feature adjustable fittings for adjusting the levels from which the layered contents are drawn through the ports from the tank interior. The tank has a large cleanout access by which personnel can access the tank interior for thorough cleanout. The compartments are organized into one or more troughs, each having a pivotal lid thereon. Lift brackets under the floor enable lifted transport of the tank by pallet jack or forklift.
