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).

A process and method of collecting, storing and utilizing the water that enters urban storm drainage systems for the purpose of utilization and reuse. Step 1 is the existing urban storm water system in an urban area. Step 2 in this process and method that store the urban storm water also serve to provide initial levels of treatment. At Step 3 is where water is diverted based on commercial versus residential water needs. Step 4.a is where water enters commercial facilities and is treated according to each commercial consumer's needs. Step 4.b is where both treated commercial waste water and water from Step 2 can be stored in subsurface geology, where some water quality treatment will occur. At Step 4, commercial facilities may also extract water for reuse. Treatment for human consumption at Step 5 would be decided by relevant government laws and regulations. This process and method has been designed to collect, store and allow for the utilization of urban storm water for the purpose of keeping polluted urban storm water out of naturally occurring bodies of water, reduce or eliminate the extraction of water from natural sources, which helps restore and maintain a healthy ecosystem. Example calculations show that in Mumbai, India, the average yearly amount of water that enters the urban storm system is greater than the combined annual average of potable and industrial needs for the city of Mumbai. In other cities, average annual precipitation that enters the urban storm drainage system of many cities provides at least half of the combined annual average of potable and industrial water needs.

The water-insoluble filler in the form of bubbles is provided into the underground cavern. Then, the filler thus provided is allowed to adhere to a bottom surface and a lower wall surface of the underground cavern to permeate thereinto. Subsequently, the filler having permeated is cured. Here, the water-insoluble filler in the form of bubbles may be provided again into the underground cavern. Moreover, water is poured into the underground cavern to float up the filler. The filler having floated up is allowed to adhere to an upper wall surface and a ceiling surface of the underground cavern to permeate thereinto. Thereafter, the filler having permeated is cured. Here, when the filler is allowed to permeate an inner surface of the underground cavern, a pressure inside the underground cavern may be increased. Additionally, when the filler is cured, a temperature inside the underground cavern may be increased.

A system for filtering produced fluid from a wellbore comprises a filter system, a solids collection vessel in fluid communication with a drain in the filter system, and a fluid line coupled to the solids collection vessel. The filter system comprises a housing defining a chamber, a filtration device disposed within the chamber, a fluid inlet disposed in the housing and configured to receive a fluid comprising suspended solids into an inlet portion, a fluid outlet disposed in the housing and configured to pass the fluid out of the housing from an outlet portion, and a drain in fluid communication with a lower portion of the housing and configured to pass at least a portion of the suspended solids out of the inlet portion of the housing.

A gas containment system can include a gas barrier layer forming a capsule. The gas barrier layer can be made up of a particulate swelling clay, a non-swelling particulate material mixed with the particulate swelling clay, water, and a water-soluble polyol. The water can hydrate the particulate swelling clay and form a continuous liquid phase in the gas barrier layer. The water-soluble polyol can be dissolved in the water. The gas containment system can further include a gas retained inside the capsule.

Individual hexagonal shaped modules used in an assembly for underground storage of storm water and other fluid storage needs. Modules are assembled into a resultant honeycomb shape for maximized structural strength and material use efficiency. Adjacent modules are in direct fluid communications with one another via openings or windows in module side walls. Assemblies include various top and side pieces along with access ports for entry into said assembly.
