This invention relates to processes for the removal of phosphorous from aqueous waste streams comprising phosphorous-containing compounds produced in the manufacture of glyphosate, in order to meet and typically exceed environmental regulations. More particularly, various embodiments of the present invention relate to the removal of phosphorous-containing compounds utilizing biological treatment system(s), oxidizing agent(s), and/or precipitant(s). The processes of the invention are also applicable to the removal of phosphorous compounds from phosphorous-containing waste streams other than those waste streams resulting from the manufacture of glyphosate.

A system for implementation or de-pollution and revitalization of artificial or natural lakes, inserted in land block and street structures around them, aiming at modulation in the artificial or natural lakes, insertion of dividing walls made of vinyl curtain, land dykes, concrete walls, or any other way, dividing the artificial or natural lake in isolated places, so there is no contact between the water of each module, considering that each module can be used for different activities, such as bathing, water sports, fishing, etc., considering that the water of the artificial or natural lake is de-polluted through the portable or the stationary treatment unit and preferably, conditioned into containers.

THIS invention relates to a method of disposing of residues from the comminution and processing of ores. The method includes the steps of classifying the processing residues into a water permeable sand fraction and a tailings fraction and depositing the tailings fraction and the sand fraction to form a multilayer structure contained by at least one containment wall (14) with the sand fraction forming continuous channels (12) through the tailings fraction (10) to allow water contained in the tailings and sand to flow by gravity, through the sand channels, to water discharge points (16), and recovering the water (18) from the water discharge points.

A product, including digestate, that has been pasteurized through thermal hydrolysis, thermal alkaline hydrolysis, or thermal carbonization is cured to enhance its marketability. Variations of this disclosure include embodiments where pasteurized material is inoculated to further enhance marketability where the inoculation is performed by injecting a fungicide, other means of inoculation by injecting beneficial microorganisms to produce characteristics in digestate that are anti-fungal or produce suitable enzyme cofactors or nutrients to stabilize digestate, injections of vitamins to enhance the ability of plants grown using select digestate to thrive in adverse conditions, injection of chemicals to enhance the ability of digestate to retain heat and prevent freezing during wintry conditions, or any combination thereof. Other embodiments include using recycled waste heat generated from wastewater treatment or another process or solar energy for accelerating the drying process which occurs before, during or after curing.

A method and a device for the continuous purification of a domestic or industrial water stream. After passing through a biological reactor to obtain a sludge of between 4 and 12 g/l of Dry Solids, the method involves feeding a series of chambers separated by restrictions at a flow rate q, injecting air into a second chamber at a flow rate Q>q, in order to obtain an emulsion, injecting a flocculant into a third chamber, and recovering the degassed emulsion in a drain pan. Flocculated and aerated sludge floats on top, such that the remaining liquid centrate has a Dry Solids content less than 100 mg/l and has a positive redox potential >50 mV and a value greater than 100 mV relative to the redox potential of the sludge at the inlet of the chambers, and is reinjected upstream from or into the biological reactor.
