  • Register Today For The Newterra Webinar: New Options & Opportunities In Decentralized Wastewater Treatment

    Decentralized systems are expanding options for municipalities, developers, and engineers to support high-quality wastewater treatment in locales that can’t sustain conventional septic systems or make it too costly to build or access centralized wastewater treatment plants (WWTP) or water reuse facilities.

  • Maximum Water Reuse, Zero Liquid Discharge — A Power Plant Case Study

    ELCOGAS, established in 1992 with the aim of building and operating a 335 MW Integrated Gasification Combined Cycle (IGCC) power plant as well as the commercialization of its technology.

  • The Importance Of pH Measurement During Industrial Treatment

    Nearly every industry requires water and wastewater treatment to some degree. From food and beverage to pulp and paper operations, influent and effluent must meet certain conditions to adhere to regulatory and/or performance requirements, and water used during the process must conform as well.

  • From Challenge & Prize Competition To Test Prototype: The Nitrogen Sensor That Could Change Residential Onsite Wastewater Treatment

    More than one in five households in the United States depend on septic or onsite systems to treat their wastewater. These systems provide critical water quality infrastructure, but they usually are not designed to remove nitrogen to the point that sufficiently protects coastal marine ecosystems. As a result, septic systems are known to contribute to eutrophication (excess nutrients), hypoxia (low levels of oxygen), and harmful algal blooms in marine and estuarine waters.

  • What Is Sustainable Flocculation And What Are Sustainable Flocculants?

    In most standard drinking water and wastewater treatment systems, there is a flocculation process that is used to reduce the concentrations of solids within the effluent stream. This particular process makes use of substances that aid in the clumping together of suspended particles among other contaminants in a clarifier system.

  • Do We Have To Sacrifice Performance To Be Green?

    The global use of membranes is widespread in municipal, industrial, and wastewater applications with reverse osmosis (RO) proving to be a highly effective and reliable method of advanced water treatment.  Reuse applications have been particularly challenging for water treatment chemical companies as these highly variable feedwaters can contain any imaginable constituent, resulting in a wide array of site specific foulants.

  • 24″ PIPELINE DELUMPER® Heavy-Duty Inline Processor

    This 24″ PIPELINE DELUMPER® was design to handle 84,000 lbs/hr of polypropylene for a major petro-chemical company. The unit features 24 inch inlet and outlet flanges, stainless steel construction and a 50 HP motor to handle oversized agglomerates of polypropylene. The unit de-agglomerates troublesome scale and lumps that can cause operational difficulties for a petro-chemical plant. Reliability is critical as the unit is to be installed extremely high up in a relatively inaccessable area.

  • Aqua MSBR® System Meets Phosphorus Removal Requirements In China Without Chemicals

    The Shenzhen Yantian WWTP is located in the Shenzhen Economic Development Zone near the Yantian port in China. The plant is partially surrounded by light industrial businesses and small jewelry factories. It occupies 11.5 hectares (28.4 acres) and serves a municipal population of about 125,000 along with the surrounding industrial amd jewelry businesses

WASTEWATER APPLICATION NOTES

  • A Comparative Study Of On-Line And Laboratory TOC Analyzers For Analysis Of Municipal Wastewater

    This application note presents comparative data obtained on influent and effluent wastewater samples using laboratory and on-line TOC analyzers employing the heated sodium persulfate oxidation technique in USEPA-approved methods 415.3 and SM 5310C.

  • Bringing Efficiency And New Confidence To BOD₅ Analysis

    Biochemical Oxygen Demand (BOD) analysis is the test everyone loves to hate—and for compelling reasons.

  • Reducing And Reusing Water In Steel Manufacturing

    The art of manufacturing steel for industries is well over 100 years old. Within this time, the steel business has fulfilled consumer needs, including construction, transportation, and manufacturing. The steel manufacturing process is quite intensive as it requires a lot of water to cool down the application. Steel plants constantly look for strategies that can help sustain the steel for a longer time by efficiently improving water and energy consumption.

  • Pipe Repair On A Budget

    A new pipe-repair solution promises to save time and money, while also being sustainable, long-lasting, fully scalable, and safe for workers.

  • Application Note: Preliminary Performance Study On An On-Line TOC Analyzer In Pharmaceutical Applications Total Organic Carbon (TOC) analysis is an effective technique for detecting and measuring the presence of organic contaminants in waters used throughout industrial processes, municipal water uses, and for determining residual concentrations of organic material on the surfaces of equipment used in the manufacture of active pharmaceutical ingredients. By Jeffrey Lane, Steve Skalski, and Gary Engelhart, OI Analytical
  • Microbial Control In Cheese Making

    Microbial contamination of food and beverage products is a potentially catastrophic occurrence resulting in foodborne illness or food spoilage. The same nutritive properties that render cheese and dairy products such a valuable food also provide an ideal growth medium for microbes if contamination occurs.

  • Dissolved Oxygen Measurement

    One of the most important measurements in the determination of the health of a body of water is its dissolved oxygen content. The quantity of dissolved oxygen in water is normally expressed in parts per million (ppm) by weight and is due to the solubility of oxygen from the atmosphere around us.

  • 'TOTEX' Is Key When Purchasing Instrumentation

    There’s a lot to be considered in the price tag of an ultrasonic instrument. Derek Moore from Siemens explains how the historical way of thinking only of capital costs needs to change to the more holistic approach of total expenditures.

  • Best Practices In Moist And Wet Gas Flow

    The Wet Gas MASSter sensor is for use in applications that have a high level of moisture or condensation present in the gas flow stream that cannot otherwise be removed.

The OPTIFLUX 2050 is an electromagnetic flowmeter (EMF) for basic water and wastewater applications. It is suitable for all cost-effective measurements where extremely high accuracy, extensive diagnostics or a wide range of communication options are not a priority. The EMF has a wide diameter range (DN25…1200 / 1…48") and all drinking water approvals. The extra isolation of the electronic device and housing makes this EMF particularly suitable for use in areas with extreme humidity.
