Abstract: An application invention "OmniSync Colloidal Processing" developed specifically for Oilsands Tailings (MFT's) Mature Fine Tailings, as demonstrated in laboratory results with samples provided as found in the original state in the Oilsands Tailings Ponds. Colloidal process effectively demonstrated immediate solidification of the fluid tailings that typically takes hundreds of years to consolidate in tailings fluid holding ponds. The "OmniSync Colloidal Processing" a clean energy technology successfully utilized an enhanced proprietary method in industrial microencapsulation for the enhancement of handling Oilsands Tailings (MFT's) with an environmental waste management of Oilsands Tailings that are generated during Oilsands extraction process to recover Oil deposits. MFT's Colloidal processes the (MFT's) and\or tailings in a non-degradable outer-shell of inert durable resin's those demonstrated in the laboratory are melamine-formaldehyde and Phenol-formaldehyde and\or consistently durable combinations for permanent allocation.   The new resulting "OmniSync Colloidal Processing" microcapsule is developed in a core-shell land\or matrix type encapsulation through insitu and interfacial polymerization procedures.  MFT's emulsion act as a sponge and absorb oils and other soluble aqueous toxins in a chemical reaction that will not allow the soluble materials and organic solvents in the mature fine tailings to escape or breakdown in extreme high PH conditions. The latter process is also achieved in a mechanical encapsulation process, the non-toxic proprietary method to successful meet requirements to fulfill a non-release hard shell microcapsule composition of which entombs MFT's through a proprietary method of emulsification of the targeted MFT's are harsh, toxic and volatile material typically difficult to manage "OmniSync Colloidal Processing" arrests all that is soluble and arrests the insoluble such as clay, sand and\or solid fines some parts of water is rejected and clear free of toxins as analysis data indicated that ranges from 7.0 to 7.8 pH Levels.   The specification had been designed for the Oilsands tailings and its long-term and accumulation and dirty oil association. Process is effective in the removal of deleterious effects that exists in MFT's streams such as solvent, carboxylic acid naphthenic acid, benzene and surfactants that is providing a very efficient water treatment solution. A safe eco-compliant alternative to MFT's that provide a immediate remediation of long-term MFT's holding ponds, along with the long term impacts to toxic releases to groundwater. The application is developed to target active materials entombed in the microcapsule therefore toxins and hazardous soluble material are no longer free to deleterious effects in the present raw form.     The method and the active materials are finely tuned to effectively never allow release of treated embodiment of MFT's, to the surrounding environment. MFT's that until this invention several existing or proposed treatments to solidification would not happen, following several years of incubation. Data revealed for every m3of raw ore in event propagates .266 m3 of Mature Fine tailings during extraction process of the Oilsands. As a standalone treatment facilities operation and process apparatus system to mass treat streams fresh tailings are utilized for recycle of process water, the mature fine tailings (MFT's) are of no longer of requirement.  Therefore MFT's are sanctioned as waste to legacy ponds of decommissioned and with no additional ability to treat water volume reduced streams. The laboratory development testing was conducted on Oilsands mature fine tailings, waste as defined in two phases sand deposits that are solid and fluid (water, Bitumen, and chemicals), or 75% solid and 25% fluid. This fluid creates massive containment ponds average 278 million m3, those 30 to 100 years to solidify. Colloidal process addresses perplexing problems of Oilsands waste, those are reclaiming disturbed land, converting fluid tailings to a solid material suitable for reclamation, treated process water suitable for release to the environment.   Ultimately mission to bring the end to accumulation and ecotoxicity of fluid tailings (MFT's) and return to ecosystems capable to allow reasonable regeneration. "OmniSync Colloidal Processing" is the method as performed in the laboratory of treating MFT's without preparation or the separation and requiring mass of energy to generate, therefore creating a sustainable solution for Canada's contribution to the world as its number one energy. Alberta will surpass Saudi Arabia diminishing oil reserve were Alberta proven reserve as future energy source to met the combined United States and China demands of 4.42 Billion tons oil energy miscellaneous uses annually.
