  • Rotork’s RHS solves valve access issue at water treatment plant

    Recent rehabilitation at the drinking Water Treatment Plant #2 in Olathe, Kansas, USA, has included the installation of Rotork IQ3 intelligent electric valve actuators to replace electric actuators from another manufacturer. In the gravity filter plant, 18 butterfly valves are situated in an area beneath a walkway which made it difficult to access and operate the old actuators. With the new ...

  • Protective coatings for Underground utility concrete structures

    As our cities and municipalities grow older, the utility and wastewater infrastructure and corrosion preventive program for underground asset protection are aging with them. Municipalities and Utility Companies are struggling to handle rehabilitation measures and effective corrosion prevention programs to deal with prolonging the life of their buried assets. More municipalities are in the process ...

    Economic Impact Of Recycling In Texas The Texas Commission on Environmental Quality (TCEQ) released its recent study on the economic impact of recycling activities in the state. Approximately 9.2 million tons of MSW designated materials were recycled in Texas in 2015. Typical recyclables (paper, plastics, metal, and glass), organics (yard trimmings, brush, green waste, and food and ...

  • Fuel preparation technology – the latest safety considerations

    The specifications for new fuel preparation technologies are becoming increasingly sophisticated, as industry innovation continues apace. But when it comes to investing in waste shredders that help manufacture cement fuels, which criteria should top the procurement wish-list in 2018? With more than 25 years’ experience in this sector, Peter Streinik, head of UNTHA’s waste shredding ...

  • Control water – control mold

    There is no single universal way to eliminate all mold growth.  But the single most effective method of controlling mold is to eliminate their source of moisture.  Moisture doesn’t just mean actual water; it can also be high humidity.  Few molds grow when the humidity is under 70%.  If they do, it is very ...

  • Control water – control mold

    There is no single universal way to eliminate all mold growth. But the single most effective method of controlling mold is to eliminate their source of moisture. Moisture doesn’t just mean actual water; it can also be high humidity. Few molds grow when the humidity is under 70%. If they do, it is very slowly. It is safe to say that you cannot stop mold growth until you stop the moisture. ...

  • Biofilm Control for Industrial Waters

    Industrial operations can face a number of serious problems due to bacterial Biofilms growing in process water systems and cooling tower waters. Biofilm-induced corrosion, mechanical blockages and impedance of heat transfer processes result in huge monetary losses each year. In engineered systems, additional risks of biofilm-mediated contamination include negative public health consequences and ...

  • Controlling Parameters in Water Analysis

    The COD (Chemical Oxygen Demand) is one of most important parameters in water analysis. In Germany as in nearly all European countries tax for indirect discharges is based on the COD. Using the oxygen consumption is reasonable in the case of tax because the delay time of waste water in a treatment plant depends mainly on its biological activity. The oxygen consumption again is a degree of ...

  • Phosphorus control protects surface waters

    Phosphorus is the decisive factor for excessive algae and plant growth in water bodies, that’s why quality standards require reductions in the amount of phosphorus released from wastewater treatment plants into rivers and lakes. In recent years, the outlet limit values have not only been reduced on national levels. Depending on the vulnerability of ecosystems, especially low target values ...

  • Controlling condensation- controlling mold

    You know those water stains on the ceiling tiles in your office that you are certain are caused by a leaky roof. Of course, the maintenance man thinks your crazy, since your office is not on the top floor. He dutifully changes the ceiling tile and a month later the water stain is back but this time it has those little black circles that look like mold colonies. Sound familiar? There seems to be ...

  • Drinking water quality control: control charts for turbidity and pH

    Water treatment processes are required to be in statistical control and capable of meeting drinking water specifications. Control charts are used to monitor the stability of quality parameters by distinguishing the in-control and out-of-control states. The basic assumption in standard applications of control charts is that observed data from the process are independent and identically ...

  • Return of drinking water supply in Paris to public control

    The ‘reclaiming’ by Paris of its water back into public hands is a paradox in the homeland of transnational water companies and at a time when the European Commission rather favours the liberalisation of public services ‘of general economic interest’. Yet what has happened is more complex. A quick historical review of management formulas in Europe reveals both the ...

  • Case Study on Water Control in a Rinsing Process

    Introduction The company selected for the study is a privately owned job shop that does rack electroplating of steel and brass plumbing and lighting fixtures with copper, nickel, and chrome. Approximately 10 operators perform the actual plating and buffing of the parts. A waste treatment specialist handles all of the wastewater requiring the necessary pH adjustment, precipitation and ...


  • UK experience in the monitoring and control of lead in drinking water

    At the zonal scale (e.g. a city or town), random daytime (RDT) sampling succeeded in demonstrating both the need for corrective action and the benefits of optimised orthophosphate dosing for plumbosolvency control, despite initial concerns about sampling reproducibility. Stagnation sampling techniques were found to be less successful. Optimised treatment measures to minimise lead in drinking ...

  • 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 ...

  • Biofilm control strategies in industrial processing waters

    Bacterial biofilms cause a number of serious problems for industrial fluid processing operations. Mechanical blockages, impedance of heat transfer processes and microbially induced corrosion result in billions of dollars of losses each year. In engineered systems, such as cooling water systems, food processing, and other industrial applications possible risk to public health and product spoilage ...

  • Controlling Odors from Waste Water Treatment Plants

    INTRODUCTION In recent years, there is growing public awareness of odors from waste water treatment plants, which mainly stems from the following observed trends: The public is less tolerant of objectionable odors from waste water treatment plants; Many waste water treatment plants have seen residential, commercial, or other developments established near the facility ...
