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.

The present invention relates to a system or method for the remediation of wastewater with a treatment media in tandem with an electrocoagulation system. The system and method also include cleaning elements for cleaning distribution lines within the system and for cleaning the electrocoagulation system.

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.

A process of dewatering any liquid/solid materials, primary-treated or non-treated sewage which includes mixing the sludge with a coagulant or flocculant aid, usually activated polymer. The sludge is then mixed and flocculated at conditions which involve extensive mixing turbulence of the sludge and whereby part of the sludge is recycled so as to be again subjected to such mixing and flocculating. Flocks form the solid particles in the sludge. The pH of the sludge is chemically adjusted into the basic pH range or to a higher basic pH. The flocked material is applied to any mechanical or non-mechanical device or a sand bed whereby the flocculated solids in the sludge are separated from the liquid in the sludge, by collecting on the top of the sand bed. The flocculated solids located on the top of the sand bed are air dried. The dried flocculated solids are removed from the top of the sand bed.

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 process to treat fines tailings generated from mining operations, wherein tailings material is sprayed onto a solid substrate as a thin layer and allowed to dry. The spray may be re-applied on top of the dried tailings film leading to multiple layers of dried tailings solids. The method may yield a solid, dry, and consolidated tailings material.
