  • Controlling scale in water systems helps prevent legionella

    The Legionella bacterium, Legionella Pneumophila (LP), the fundamental agent of Legionnaire’s Disease, is a water-based organism, which causes infection when inhaled in an aerosol form. Legionnaires' Disease acquired its name in 1976 when an outbreak of pneumonia occurred among persons attending a convention of the American Legion in Philadelphia. Later, the bacterium causing the illness ...

  • Calcium Sulfate Scale Control with ML2580

    Background Mining company operates an ore roasting operation for gold recovery in the western US. SO2 is generated in the process and quenched with water creating a super saturated stream of SO4 . Calcium sulfate (gypsum) scale forms in the process plumbing and reduces critical flow rates. After months of reduced production, the decision was made to shut down and hydro-blast the system. The ...

  • Controlling Scale Deposition and Industrial Fouling

    It costs US industry billions of dollars a year to control and remove the limescale that builds up in industrial equipment such a heat exchangers, evaporative coolers, boilers, chillers and other water fed equipment. Oil wells, for example, face significant scaling problems from the highly mineralized water that are extracted with the oil. Limescale not only increases downtime, maintenance ...

  • Control of trichloroethylene plume migration using a biobarrier system: a field-scale study

    The objective of this field-scale study was to evaluate the effectiveness of controlling trichloroethylene (TCE) plume migration using the polycolloid substrate (PS) biobarrier. The developed PS (containing soybean oil, lactate and surfactants) could release substrate to enhance the TCE dechlorination. In this study, a biobarrier comprising PS injection wells was installed. Injection wells were ...

  • Coordinating multiple model predictive controllers for the management of large-scale water systems

    The optimal management of multi-purpose water reservoir networks is a challenging control problem, because of the simultaneous presence of multiple objectives, the uncertainties associated with the inflow processes and the several interactions between the subsystems. For such systems, model predictive control (MPC) is an attractive control strategy that can be implemented in both centralized and ...

  • Controlling scale deposits in the pulp & paper industry

    The pulp and paper industry is one of the heaviest users of water within the North American industrial economy, requiring on average 54 cubic meters of water per metric ton of finished product.  As water is used in nearly every part of the manufacturing process, accumulation of scale is a phenomenon that can occur in all pulp and paper making processes. This occurs even with the purest water ...

  • Real time control for reduced aeration and chemical consumption: a full scale study

    The use of the activated sludge process (ASP) for the nitrification/denitrification of wastewaters is commonplace throughout the UK and many other parts of the industrial world. Associated with this process are significant costs arising from aeration requirements and for selected sites, the need to provide an external carbon source. These costs can constitute up to of 50% of the total running ...

  • A Struvite Control and Phosphorus Removal Process for Centrate: Full-Scale Testing

    ABSTRACTThe North End Water Pollution Control Centre (NEWPCC) in Manitoba, Canada serves a population of approximately 380,000. The dry weather flow to the NEWPCC is approximately 175 ML/d (46 MGD). The plant uses anaerobic digestion and centrifuge dewatering in its solids treatment train. The centrate stream comprises approximately 20 percent of the plant’s phosphorus load. The plant suffers ...

  • Advanced nitrogen removal using pilot-scale SBR with intelligent control system built on three layer network

    Since eutrophication has become increasingly severe in China, nitrogen and phosphorous have been the concern of wastewater treatment, especially nitrogen removal. The stabilization of the intelligent control system and nitrogen removal efficiency were investigated in a pilot-scale aerobic-anoxic sequencing batch reactor (SBR) with a treatment capacity of 60 m3/d. Characteristic points on the ...

  • Full-scale SVE system operates in tandem with groundwater treatment

    Since 1993, SVE has been implemented using two designs at the TP Industrial, Inc. (TPI) site in Gardena, CA, to treat soil contaminated with chlorinated solvents. The SVE system was modified in 1997 to improve emissions control efficiency by using carbon adsorption units that treat effluent from an air-stripping system for treating site ground water. By the end of 2007, SVE had removed a ...

  • Real-time modeling of trihalomethane formation in a full-scale distribution system

    Using a combination of modeling and online water quality instrumentation, utilities can produce real-time predictions of trihalomethane (THM) formation in their distribution system.
