INDUSTRIAL WATER AND WASTEWATER TREATMENT

Henan Beyond Clarification: Optimizing Polyacrylamide Selection For High-Complexity Industrial Wastewater Treatment
Polyacrylamide (PAM) selection in industrial wastewater treatment is frequently reduced to a trial-and-error exercise, resulting in reagent waste, inconsistent effluent quality, and inflated operating costs. This article presents a structured framework for PAM optimization across three critical variables — ionic charge density, molecular weight, and coagulant synergy.

  • Coriolis Installation At Brewery Indicates Bright Future For SITRANS FC330

    A global beverage company produces, markets, sells and distributes a variety of beverages including beer, malt, soft drinks, fruit juices and mineral water. The brewery has utilized several types of SITRANS F flowmeters from Siemens to regulate all aspects of the brewing process for more than a decade, including SITRANS F C Coriolis meters to monitor the sugar concentration in wort prior to fermentation.

  • Advances In Flowmeter Technology

    This article disucsses two trends turning the flowmeter industry on its ear: advances in flowmeter diagnostics and the adoption of smartphone-like technology to improve access and communications.

  • AnoxKaldnes MBBR Reduced Wastewater OPEX At Meat Processing Facility

    Valley Pride Pack wanted to reduce the operational costs associated with their wastewater treatment system.

  • Aeration Considerations: What To Know Before You Buy

    Unlike most municipal wastewater treatment plant (WWTP) applications, industrial wastewater can vary widely from one application to another, even within the same plant, depending on the process being run. Industrial wastewater professionals — especially those facing specific challenges or planned volume increases — can benefit from comparing key points of differentiation in jet aeration system options before making any upgrade.

WATER AND WASTEWATER SOLUTIONS FOR THE POWER GENERATION INDUSTRY

  • Developments In Heat Transfer Technology Can Improve Exchanger Efficiency And Reduce Water Demand

    Water’s high heat capacity, high thermal conductivity, and historically low cost make it popular for process heat exchange. Power plants, especially those for liquid cooling applications, withdraw a large fraction of the total demand for water necessary for agriculture, industry, recreation, hygiene, drinking, and wildlife.  By Kevin J. Farrell and Vijay Sathyamurthi, Heat Transfer Research, Inc., College Station, Texas USA

  • Cooling Tower Crisis: How Hydrogen Peroxide Scrubbed Away The Bacteria Buildup

    A West coast power plant needed an immediate solution to clean its cooling tower that was fast, cost effective, and did not require removal and manual cleaning of the tower's fill material. 

  • Filtration System For Thermoelectric Plant

    AES Gener is the second generating company in Chile and the main thermoelectric generator, and provides 4.068 MW (including Guacolda S.A.), equivalent to a share of 22%, whereas 3.797 MW of thermoelectric capacity and 271 MW of hydroelectric capacity.

  • Texas' Evolving Energy Reality: Clean Energy Uses Less Water

    It’s been an interesting time for water in Texas. Beyond the incredibly wet and cool spring we’ve been having, Memorial Day saw the second year in a row of record-breaking floods.

  • Filter Installations Remove Solids From FGD Scrubber Effluent

    Power plants and refineries around the world must manage and treat complex effluent waste streams from the Flue Gas Desulfurization (FGD) process. Flue gas is generated by the combustion process of fossil and fossil-derived fuels, such as coal, oils, and natural gas in power plants. Petrochemical refineries may generate flue gas from a number of different processes, including Catalytic Cracking, Steam Methane Reforming, and Heaters or Furnaces.
