Abstract: A method for acidizing subterranean formations may include providing a treatment fluid comprising an aqueous carrier fluid, an acid, and a chelating agent comprising N-(phosphonomethyl)iminodiacetic acid, the treatment fluid having a pH at or below that at which carboxylic or phosphonic acid groups of the N-(phosphonomethyl)iminodiacetic acid are protonated and the chelating agent is ineffective for complexing a metal ion; introducing the treatment fluid into a wellbore penetrating a subterranean formation comprising a carbonate mineral; reacting the acid with the carbonate mineral in the presence of the chelating agent, such that the acid at least partially spends as the pH of the treatment fluid rises; and complexing a metal ion with the chelating agent once the pH of the treatment fluid rises above a pKa value for one or more of the carboxylic or phosphonic acid groups of the N-(phosphonomethyl)iminodiacetic acid.

Abstract: A wastewater purification system includes first purification equipment (101) for receiving wastewater and for outputting first time purified wastewater and sludge, and second purification equipment (102) for receiving the first time purified wastewater and for outputting second time purified wastewater and purification residue. The second purification equipment is based on the reverse osmosis and/or nanofiltration technology. The wastewater purification system further includes combustion equipment (103) for burning the sludge so as to produce heat, and dryer equipment (104) for drying the purification residue with the aid of the produced heat. Hence, the sludge produced by the first purification equipment is used for producing heat for drying the purification residue which is produced by the reverse osmosis and/or nanofiltration technology and whose initial water content is so high that it is problematic to be disposed of without drying.

Abstract: Disclosed is a sludge processing system having a centrifugal separator concentrating the sludge and a furnace heat-treating the concentrated sludge. It allows automatic control in which the operational condition of the centrifugal separator operates under optimal conditions according to the operational state of the furnace. The control device sets a variable range of a differential speed between the bowl and screw conveyor of the centrifugal separator, and variably controls the differential speed so concentrated sludge convey torque of the screw conveyor achieves a torque corresponding to a moisture content requested by the furnace within the variable range, when the differential speed varies within a certain previously set range and the concentrated sludge convey torque of the screw conveyor maintains the torque corresponding to the moisture content requested by the furnace for a certain period of time being previously set, changes a control value of the centrifugal force and the torque.

The invention describes methods to create a thixotropic or paste-like material via the application of mixing energy to the organic sludge followed by an alkaline treatment and a subsequent ammoniation. The invention further describes a method to increase the plant nutrient content in the organic containing product to a level which permits the finished granular fertilizer product to compete in the commercial agricultural fertilizer marketplace. Further, the invention reduces odors associated with said organic-containing sludges.

Abstract: In order to render sewage sludge suitable for beneficial purposes, it must be disinfected and stabilized. EDC deactivation is rapidly becoming a desirable result of any sludge or biosolids treatment process. Disclosed herein is a process of treating sewage sludge so as to stabilize the sludge that involves the presence of an iron-containing compound during dewatering of the sludge. Process embodiments described also achieve biosolid samples that have reduced EDC activity, Other embodiments disclosed involve use of a combination of iron salts ferrate and ferric chloride that are added to wastewater sludge in the dewatering step before heat drying. The biosolids resulting from sludge treated with aniron-containing compound are able to resist putrefaction for more than two to three weeks.
