  • The Benefits of an Integrated Air and Water Pollution Control Partner

    Although there has been substantial progress during the past several decades in reducing pollution, the EPA, other federal agencies and local governments continue to add and revise requirements and standards, making compliance a challenge for the industrial sector. These companies also face increasing public pressure not just to meet but to exceed pollution control standards, as studies continue ...

  • Water testing 101: TDS

    According to Wikipedia, total dissolved solids (TDS) is defined as “the combined content of all inorganic and organic substances contained in a liquid that are present in a molecular, ionized or microgranular suspended form.” The article goes on to state that “total dissolved solids are differentiated from total suspended solids (TSS) in that the latter cannot pass through a ...

  • The role of process water in pathogen reduction

    The USDA’s Pathogen Reduction/Hazard Analysis and Critical Control Point (HACCP) rule in July of 1996 required all meat and poultry slaughter plants to adopt a system of process controls to prevent food safety hazards. It contained four components: standard operating procedures (SOPs) for sanitation, HACCP plans, generic E. coli testing and Salmonella performance standards. With the ...

  • The use of potassium permanganate, ozone and associated coupled processes for odor removal in drinking water: bench and pilot scale tests

    Bench and pilot scale experiments were conducted to investigate and compare the preoxidation effects of potassium permanganate (KMnO4) and ozone (O3) for odor removal in drinking water. The effects of dosage, contact time, pH, as well as couple treatment with a granular activated carbon (GAC) filter were examined using bench experiments, while the effects of KMnO4 dosing ...

  • Atchafalaya run - CETCO oilfield services process for treating pipeline hydrostatic test water during pigging operations

    A major pipeline company recently conducted hydrostatic testing and pigging operations on 56 miles of pipeline in south central Louisiana. The original plan for the project was to flood the pipeline with water from the Atchafalaya River and perform multiple pig runs while discharging the water from the pipeline back into the river. The company assumed the fluids returning from the pipeline would ...

  • Optimizing the coagulation process in a drinking water treatment plant – comparison between traditional and statistical experimental design jar tests

    In this study of coagulation operation, a comparison was made between the optimum jar test values for pH, coagulant and coagulant aid obtained from traditional methods (an adjusted one-factor-at-a-time (OFAT) method) and with central composite design (the standard design of response surface methodology (RSM)). Alum (coagulant) and polymer (coagulant aid) were used to treat a water source with ...

  • Application of batch tests to assess antibiotic loads in anaerobic processes

    The presence of antibiotics in drinking water and wastewater has not been widely studied because the sanitary engineering sector mainly focuses on the removal of organic matter and nutrients. There is a lack of environmental regulations for pollutants like antibiotics. Batch tests analyse biodegradability to measure the anaerobic degradation potential of the substrate, or they can be used as ...

  • 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 ...

  • Plot testing of mbbr and ifas treatment processes for nitrification and denitrification at the mamaroneck wwtp

    ABSTRACT The Mamaroneck WWTP is one of four WWTPs in Westchester County that the New York State Department of Environmental Conservation (NYSDEC), through its State Pollution Discharge Elimination System (SPDES), imposed Waste Load Allocation (WLA) limits for nitrogen because of its discharge into the ...

  • Low cost processes for the removal of phosphates in water and wastewater

    This paper presents a synopsis of various low-cost techniques employed for the removal of phosphates from water and treated wastewater. Techniques employed include seawater flocculation and coagulation/flocculation using bittern, adsorption on fluidised raw dolomite bed, and filtration through iron and aluminium coated filter media. Seawater flocculation at a seawater concentration of 10% ...

  • Effectiveness of priority PAH removal in a water coagulation process

    The paper presents results of research on the removal of priority hazardous polycyclic aromatic hydrocarbons (PAHs) (anthracene, benzo[a]pyrene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[g,h,i]perylene, indeno[1,2,3-cd]pyrene) from water in the coagulation and sedimentation process. Coagulants chosen for the analysis were aluminum(VI)sulfate and two pre-hydrolyzed coagulants – ...

  • New Process Gas Analyzer for the Measurement of Water Vapor

    KEYWORDS TDLAS, WMS, Laser Spectroscopy, Water Vapor Measurement, Gas Analyzer ABSTRACT A new analyzer for the measurement of water vapor concentration based on Tunable Diode Laser Absorption Spectroscopy (TDLAS) was developed. The water-vapor line at 1854-nm was selected for the measurement, and the performance of the system was evaluated on different ...

  • Minnesota makeover - treating hydrostatic test water

    A pipeline company in Minnesota conducted a hydrostatic test of its pipeline, producing approximately 320,000 barrels of fluid for treatment. Fluid was pumped from the pipeline into three storage tanks located at the pipeline’s tank farm. Fluid was then pumped from the storage tanks directly to CETCO Oilfield Services onsite equipment. On average, CETCO Oilfield Services treated the fluid at a ...

  • Food Processing: Odor Control in Edible Oil Processing

    Abstract: The problems with odor around a typical edible oil deodorizer are discussed in detail, and a three-step solution to eliminate these problems is presented. The three steps are a distillate recovery system which recovers most of the fatty acid in the deodorizer vapor discharge as a valuable byproduct, a closed loop barometric cooling water system which keeps the fatladen ...
