An apparatus for preparing and dispensing a flocculant solution to dewatering an aqueous process stream includes a mixing pump, a maturing tank, and a feeding unit. The mixing pump mixes the flocculant solution and builds up a pressure onto the flocculant solution. The maturing pressure tank is fluidly connected with the mixing pump, so that the pressurized diluted flocculant solution is led from the mixing pump into the maturing pressure tank and matured therein under pressure that is above atmosphere pressure.

A system for transferring marine life within an aquaculture facility including a plurality of segregated storage facilities each containing water for marine life, maintained within a predetermined temperature range and supported at independent ground levels. The storage facilities are successively disposed and structured to contain marine life at different stages of growth. A transfer assembly includes a path of fluid flow interconnecting successive ones of said plurality of storage facilities in fluid communication with one another, wherein at least a majority of a length of said path of fluid flow is disposed beneath the independent ground levels at a predetermined depth, which is sufficient to facilitate maintenance of the path of fluid flow within the predetermined temperature range, via geothermal cooling. The transfer assembly may also connect a holding facility, which may be dimensioned and structured to transfer mature marine life, possibly on an on-demand basis, to the harvesting facility.

A method of extracting water from sludge, wherein the sludge includes a magnetic ballast, wherein the sludge is positioned on an interface. It includes applying a magnetic treatment to the magnetically-ballasted sludge to extract water from the sludge.

The present invention relates to intelligent oil sludge treatment apparatuses and treatment processes. The treatment apparatus includes an integrative device, an oil removal device, a separation device, a sludge collection tank, a dewatering device, a pyrolysis device, an agent tank, a deodorization tower, a crude oil tank, a light oil tank, a separator, a condenser, a desulfurization tower, a clean water tank, a sewage station, and a steam boiler, where an outlet of the integrative device is connected to an inlet of the oil removal device; the oil removal device is configured to remove crude oil from oil slurry; the oil removal machine collects the crude oil to the crude oil tank, discharges stench into the deodorization tower, and discharges the slurry into the separation device; and the separation device is configured to perform a solid-liquid separation operation.

A thickener for dewatering fluids having a vessel with a central well extending proximate a top portion of the vessel to a lower cone-shaped portion, a hindered settling zone, and a compressible sediment layer zone within the lower cone-shaped portion. Eductors housed in inlet wells have an inlet nozzle and a mixing tube to receive slurry to be treated and clear fluid to be mixed with the slurry. The fluid from the eductors is directed in counter circular paths via circular chambers situated proximate the inlet wells, such that fluid flowing in each direction collides and forms turbulence within the central well. Resultant fluid is directed into a lamella-type separator circumferentially located about a portion of the central well, having layered fluid paths directed radially outwards from said center longitudinal axis and upwards towards said vessel top portion through a conical, inclined fluid path, plate structure. The eductors are adjustable with a movable iris for limiting the amount of clear fluid exiting the eductor.

A system of treating waste materials (28) is provided, and includes a waste treatment reactor (10) configured to treat the waste materials. The waste treatment reactor (10) has a cylindrical body (12) having an inlet (14) to receive the waste materials, a waste chamber (26) to store the waste materials, and an outlet (16) configured to deliver treated waste materials out of the waste chamber. A bundle reactor (38) has the waste treatment reactor and performs a waste treatment for the waste materials stored in the waste chamber. An energy recirculation assembly (40) is connected to the bundle reactor and recirculates thermal energy associated with the bundle reactor during the waste treatment. The energy recirculation assembly (40) has a heating unit (42) to heat a first region of the bundle reactor, and a cooling unit (44) to cool a second region of the bundle reactor.

Provided is a highly efficient pipe-type flocculation mixer, comprising: a feeding pipe, a mixing pipe, a discharging pipe and a mixer. The feeding pipe, the mixing pipe and the discharging pipe are disposed in parallel and sequentially communicated. The mixing pipe is a circular pipe and has two blind ends. The mixer comprises a driving motor, a mixing blade and a central shaft. One end of the central shaft is coupled to the driving motor, and another end of the central shaft is coupled to the mixing blade. The size of the mixing blade enables the mixing pipe to exactly accommodate the mixing blade. Also provided is a feeding-mixing device, wherein an agent can be introduced into a hollow central shaft via an agent feeding chamber, and be sprayed out from the central shaft into a mixing chamber; said agent feeding manner enables sufficient mixing.
