A process for the treatment of thick fine tailings that include constituents of concern (CoCs) and suspended solids is provided. The process includes subjecting the thick fine tailings to treatments including chemical immobilization of the CoCs, polymer flocculation of the suspended solids, and dewatering. The chemical immobilization can include the addition of compounds enabling the insolubilization of the CoCs. Subjecting the thick fine tailings to chemical immobilization and polymer flocculation can facilitate production of a reclamation-ready material, which can enable disposing of the material as part of a permanent aquatic storage structure (PASS).

Embodiments of the present disclosure include systems and methods for collecting, storing, separating, and disposing of waste material from an oil and gas well site in order to enhance payload efficiency. An embodiment of a method, for example, may include introducing a waste material into an enhanced-payload mobile vessel positioned at the oil and gas well site, the waste material selected to include one or more of a sludge waste material, a solids-laden wastewater material, and a dry waste material. The method may further include transporting the waste material when positioned in the enhanced-payload mobile vessel along roadways to an off-site waste management facility. Additionally, the method may include dumping the waste material from the enhanced-payload mobile vessel by a site-based lifting mechanism into a receiving vessel at the off-site waste management facility thereby to dispose of the waste material at a reduced transportation cost.

The present invention relates generally to an effluent treatment device including in one embodiment a skid configuration. The method and apparatus of the present invention can use only two fluid pump units and including individual or multiple membrane modules in a stacked longitudinally arranged configuration. The stacked or in series modules can be either vertical or horizontal forming a column. The membrane modules are contained in large diameter pipes with enough space around each module so that filtered permeate water collects in the pipe and backwash water can flow in the pipe to backwash the modules and contained membranes. The present invention includes one or more hollow fiber ceramic membrane modules which each includes multiple hollow fibers bundled together by end or band caps (e.g., ceramic, epoxy of glass material end caps) to form a complete membrane module. A complete hollow fiber membrane module can comprise multiple symmetric individual hollow fibers between about 2.0 to 4.00 millimeters inside diameter and can be made of aluminium oxide (Al.sub.2O.sub.3) substrate material. The geometry of the individual ceramic fiber walls can be between about 1.0 to 2.0 millimeters in thickness, known as the membrane wall. Such ceramic hollow fibers can have pores including a range of nominal 1 nanometer to 1400 nanometers. The ceramic hollow fibers can comprise selective membranes pores including a range of nominal 1 nanometer to 1400 nanometers which may include individual or multiple separating layers attached to the fiber walls of nominal 1 to 100 nanometers. The separating layers can each be a porous polymeric material. In one embodiment, a skid mounted treatment device is operable to pass water through an individual hollow fiber ceramic membrane module or multiple membrane modules in series known as a membrane loop. Filtration is inside to out flow filtration through the hollow fiber membranes. The apparatus is also operable to pass water through the hollow fiber ceramic filter module or multiple membrane modules in an outside to in flow direction, so as to remove material from the separation layer of the hollow fiber ceramic membrane fibers, a process known as backwashing or back flushing. Contaminant materials (retentate) having been deposited during inside-out filtration of the commercial or industrial laundry effluent is removed with such back flushing.

A waste liquid solidification system includes a chamber at least partially enclosing a volume, a liquid outlet positioned to spray a liquid into the volume, and a powder outlet adjacent the liquid outlet positioned to discharge a super-absorbent polymer powder into the volume. The liquid outlet and powder outlet are configured such that the liquid and the super-absorbent polymer powder undergo airborne mixing within the volume enclosed by the chamber to create a solid waste.

The present invention provides a method of treating a commercial or industrial laundry wastewater stream. The method and apparatus treats a commercial laundry waste stream from a commercial washing machine or machines wherein the waste includes total suspended solids, chemical oxygen demand, biological oxygen demand, turbidity, and bacteria. The waste stream is transmitted to a first treatment unit that has a membrane filter that filters particles of between about 6 and 40 nanometers. At the first treatment unit, the waste stream is separated into a permeate stream and a retentate component. The retentate component is transmitted to a second treatment unit that filters particles of between about 3 and 10 nanometers. The permeate stream is then transmitted to a permeate holding vessel after treatment in the second treatment unit. The retentate component is placed in a mixing vessel where it is mixed with a polymer to form a solid waste.
