A method of removing barium, calcium, strontium, and magnesium from frac flowback. A sulfate reagent and carbonate reagent are mixed with the frac flowback, causing barium, calcium, strontium, and magnesium to precipitate. The precipitants are crystallized and the resulting frac flowback and crystals are separated into relatively heavy solids and a stream of relatively light solids. The stream of relatively light solids is subjected to a further separation process that produces sludge that is recycled to aid in the crystallization process and a treated effluent which is recycled to the fracking operation or collected and used in another fracking operation.

A processing method for perennially and deeply polluted sludge containing oils and water, waste residues, or oil sands in natural oil mines, and a processing system thereof. In the method, a solid substance containing oils and water is in full contact with an organic liquid solvent with a low boiling point and a weak polarity or no polarity at room temperature under pressurized condition to extract oil and water from the solid substance to the liquid, the organic solvent with low boiling point and low latent heat is easily separated from oil and water in the liquid after solid-liquid separation by decompression or heating evaporation, the gas solvent is compressed and condensed for recycling, the extracted oil and water are subjected to oil-water separation, and the extracted oil may be used as fuel or used for refining.

An apparatus, method and system is provided for treating sewage sludge by dewatering the sewage sludge, heating the sewage sludge being treated to destroy pathogens, and then reducing volatile solids in the sewage sludge being treated through biochemical decomposition to produce a treated biosolids product that meets government regulations for pathogen reduction and vector attraction reduction.

Disclosed herein are processes for treating high-P fluid involving (1) providing a high-P containing stream; (2) chemically treating the high-P stream such that a majority of dissolved P in the stream is transformed into a solid form via sorption of P onto particles placed or precipitated within the stream; and (3) removing the solid form containing P from the chemically treated fine solids stream, such that >about 90% of the total P is removed from the high-P fluid. Also disclosed are systems for treating a high-P stream, the systems involving (1) a chemical treatment station operable to chemically treat and transform equal to or greater than about 90% of dissolved P in a high-P stream into a solid form; and (2) a liquid-solid separator station operable to remove the solid form containing P from the chemically treated high-P stream.

The present disclosure relates to a method for treating and recycling, in an environment-friendly manner, sludge and waste water generated in a process for crushing waste concrete and recycling waste concrete into aggregates. Sand is separated from sludge configured from cement components and sand components and is recycled as fine aggregates, and the cement components can be used as concrete admixtures. Furthermore, the present invention introduces a mineral carbonation technique and thereby allows pH of waste water to satisfy an environmental standard and allows high value calcium carbonate to be produced.

The present invention relates to a method for flocculating and dewatering oil sands fine tailings. Said method comprises mixing the aqueous mineral suspension with a poly(ethylene oxide) (co)polymer to form a dough-like material. The material is then dynamically mixed in an in-line reactor to break down the dough-like material to form microflocs having an average size of 1 to 500 microns, and to release water. The internal diameter of the in-line reactor is at most five times the internal diameter of the inlet pipe of the reactor. The suspension of microflocs has a viscosity of at most 1000 cP and a yield stress of at most 300 Pa.
