The present invention relates to a self-contained unit having a system for recovering polymer over spray from a pallet coating process. The self-contained unit includes a common enclosure having at least four walls, a ceiling and a floor. There is a collection tank located below the floor of the common enclosure and a roof platform is located above the ceiling of the common enclosure. Within the common enclosure is at least one spray booth having a waterfall wall with liquid flowing down a face of the waterfall wall to the collection tank. Mounted on the roof platform is a consolidation tank, hydrocyclone and pressure filter that are all part of the system for removing the polymer from the over spray mixture collected at the collection tank.

A separation device and method for treating effluent mixture streams including one or more liquid component(s). The device and method can utilize gravity and/or hydromechanical separation to separate non-water components from the effluent mixture. The device and method more particularly relates to an improved large capacity grease interceptor having an integrally formed double baffle sidewall within the tank reservoir to control the movement of effluent mixture within the reservoir, as well as significantly improve structural integrity of the device and ease of manufacturing and assembly.

Disclosed is a rake-free thickening device including driving area. The device includes a feed assembly, a diversion assembly and a clean coal collection assembly. The clean coal collection assembly includes a driving area. The diversion assembly includes a central tank. Slime water passes through the feed assembly and flows with a medicament from an upper part of the central tank to a middle of the central tank, and then diffuses around. Bubbles carry the fine slime up after reacting. The driving zone drives the dispersed bubbles to a defoaming zone located in the middle of the central tank. The slime water in the central tank flows through the central tank after defoaming. With the continuously filling of slime water, the slime water above the central tank overflows the central tank to the clean coal collection assembly within the diversion and settlement area.

The present disclosure provides for devices, systems, and methods of separating PFAS compounds from wastewater leachate. After separation, the PFAS compounds can be rendered less harmful. The present disclosure provides for devices, systems, and methods that uses aeration-induced foaming to isolate PFAS from landfill leachate into a concentrated, volume reduced liquid (coalesced foam), which can be separated and treated.

In an insoluble material-generating apparatus, an iron salt and/or an aluminum salt, and a cationic polymer flocculant, are added to waste water containing dissolved substances to generate insoluble material. To the insoluble material-containing waste water, an anionic polymer flocculant is added, after which the waste water containing the anionic polymer flocculant and the insoluble material is stirred in a granulating flocculation precipitation tank, the insoluble material is granulated, and solid-liquid separation of the generated granulated material is performed to obtain treated water. The amount of the iron salt or the aluminum salt added is an iron or aluminum concentration of at least 0.4 mmol/L, and the cationic polymer flocculant and the anionic polymer flocculant are added so that the product of the cationic polymer flocculant concentration and the cationic group percentage is equal to or less than the product of the anionic polymer flocculant concentration and the anionic group percentage.

The present system is for simultaneous recovery of purified water and dissolved solids from impure high TDS water (1) which is achieved in a single step and eliminates the use of external thermal energy for making the system significantly efficient. It eliminates the use of boiler, cooling tower that reduces the overall capital cost and continuous requirement of external thermal energy for making system efficient. The simultaneous recovery of the purified water and solids from high TDS input effluent reduce the energy intensity of the system. Said system provides a vacuum system as heat pump which enables the system to be self-sufficient in thermal energy requirements for evaporation process and reduces GHG emissions significantly.

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.

A single stage clarifier and mixing assembly includes a housing, a mixing section within the housing and a clarifier section within the housing. The mixing section includes a mixing chamber having (a) an inlet, adapted for delivering an inlet stream to the mixing chamber, at an upper end, and (b) a mixing section outlet at a lower end. The clarifier section extends concentrically around the mixing section. The single stage clarifier and mixing assembly also includes an agitator adapted for mixing the inlet stream in the mixing chamber.

A fluid treatment system is provided. A clarification reactor or chamber, configured for receiving an influent, is provided wherein separated water and separated solids may be formed from the influent while inside and/or outside the reactor. An influent inlet, positioned essentially at the top of the reactor, configured to allow the influent to enter the reactor is provided. A separated water outlet is provided, positioned essentially at the top of the reactor, that is configured to allow the separated water to exit the reactor. A solids discharge is also provided, positioned essentially at the bottom of the reactor, that is configured to allow the separated solids to exit the reactor. A downward angled baffle, positioned inside the reactor, is configured to deflect the separated solids towards the solids discharge.
