  • Clarifiers-No, Filtration-Yes: A Case Study

    Problem Twenty miles southeast of Coos Bay, Oregon situated at the conjunction of the North and South Forks of the Coquille River lays the town of Myrtle Point. Just five years ago this community of 2670 residents was facing a large potable water problem with an even larger price tag. The town feeds its water treatment plant from the North Fork Coquille River. Prior to the 1990s the water ...

  • Parameters affecting steady-state floc blanket performance

    A laboratory-scale reactor was used to simulate a water treatment process sequence of rapid mix, hydraulic flocculation, upflow clarification with a floc blanket, and lamellar sedimentation to accomplish removal of colloidal particles. This study focused on variables affecting performance of the floc blanket including: provision of hydraulic flocculation, raw water turbidity, coagulant dose, ...

    MATRIX: Soil ANALYTE: Carbaryl RANGE OF DETECTION: 40 to 500 ppb MATERIALS: SDI Carbaryl RaPID AssayÒ kit and Sample Diluent. SDI RaPID PrepÔ Soil Collection Kit (optional). SDI RaPID PrepÔ Extraction Kit: Type II (extraction solution, optional) Reagents: Methanol (pesticide grade), distilled or ...


  • Wastewater-Primary Treatment

    Primary Treatment is defined as a wastewater treatment process that takes place in a rectangular or circular tank and allows those substances in wastewater that readily settle or float to be separated from the water being treated. This process achieves solids separation. The solids readily available to settle to achieve sedimentation will do so in a settling tank referred as a clarifier. On the ...

  • Zhuhai --a membrane based water treatment plant

    The Facility At the time it was built, the Guangdong Zhuhai Power Station set a number of firsts for China. Not only was it the largest thermal power plant in terms of unit size , it was the first to use Reverse Osmosis Water Treatment and it was the first to be financed without a multilateral or government guarantee. Zhuhai was also EPC Mitsubishi Heavy Industries’ first turnkey ...

  • Detection of carbofuran in soil

    MATRIX: Soil ANALYTE: Carbofuran RANGE OF DETECTION: 10 to 500 ppb MATERIALS: Carbofuran RaPID AssayÒ kit and Sample Diluent. Reagents: methanol (pesticide grade), distilled or deionized water. Equipment: reciprocating shaker, plastic bottles (polypropylene or high density polyethylene, 50 or 60 mL) with ...


  • Metal finishing - Columbia manufacturing company - case study

    Application Columbia Manufacturing Company of Westfield, Massachusetts began producing bicycles in 1877. The company, while still producing bicycles, transitioned its core product line to institutional furniture with chrome plated bases made from tubular steel. Large amounts of potable water were required for the old plating system. The company was using 180,000 gallons of potable water a ...


  • Treatability Studies of Anaerobic/Aerobic Tomato-Processing Wastewater Treatment Systems: Pilot vs. Bench

    ABSTRACTTomato-processing wastewaters generated from food-canning industry are typically considered difficult to biodegrade since they contain seed, skin and high particulate and colloidal fractions. A bench-scale and a pilot-scale anaerobic/aerobic system were evaluated and compared for the treatment of high-strength tomato-processing wastewater. The pilot-scale and bench-scale systems had ...

  • New treatment plant to feature ceramic membranes

    The Parker Water and Sanitation District (PWSD) in Colorado has contracted for a membrane treatment system for its Rueter-Hess water treatment plant project. The new plant will treat water from the Rueter-Hess Reservoir (RHR), which is being built three miles southwest of downtown Parker on Newlin Gulch, which is a tributary drainage of Cherry Creek. The reservoir and associated treatment plan ...

  • Membrane Bioreactors for RO Pretreatment

    ABSTRACTCurrently, treated municipal wastewater is typically discharged to the environment in most parts of the world. It is, however, a potential water resource from which high quality water for reuse can be produced. Reuse applications include both non-potable applications such as irrigation and production of industrial process water, and indirect potable reuse including aquifer recharge. For ...

  • Do not make the waste energy saving lamps into a scourge

    As early as August 1, 2008, the national list of hazardous waste had been the recovery of the energy saving lamps included. However, for waste energy saving lamps may harm caused to the environment and human health, the public did not know. Until now, energy saving lamp recycling policy is still blank. How future waste disposal? Than ordinary incandescent lamp,  ...

  • Do You Need a Raw Water Treatment System for Your Plant?

    Determining whether or not you need a raw water treatment system for your industrial facility can be a difficult decision. But if your plant draws from a raw water source (such as a river, lake, ocean, or groundwater), chances are you will need some sort of treatment. If left untreated, what is present in your water source can cause a variety of issues, such as contamination in drinking water ...

  • Reclaimed Municipal or Industrial Wastewater for Power Plant Cooling & Boiler Feed Make-Up Water

    For centuries, water was considered a commodity product and used with little or no restriction. In today’s modern society, water is now being considered a precious resource and considerable effort is put into protecting, recycling, and restricting its use freely. State and Federal agencies have put in place guidelines and regulations restricting its use, especially for industrial use. ...

  • Erosion and Sediment Control: Navigating NPDES Regulations, the SWPPP, and Techniques for Compliance

    Erosion and Sedimentation: Why Are They a Problem? The US Environmental Protection Agency lists sediment as the single most common pollutant in rivers, streams, lakes, and reservoirs. With all the potentially harmful chemicals and substances in the world, it seems odd to many people that sediment—dirt, essentially—is singled out as the major culprit. Yet these particles of ...

  • Toxicological and Environmental Safety Data - Case Study

    Introduction AGRAGEL is a cross-linked copolymer of acrylic acid and acrylamide partially neutralized as potassium/ ammonium salt. The polymer is in its dry form a granulate and forms a gel-like material upon addition of water or aqueous solutions. Due to the cross-linking it is insoluble in water. Uptake of water is facilitated mainly by the negative carboxylic groups of the polymer and ...
