  • Control Algae and Improve the Water Quality in Waste Stabilization Ponds

    Due to population growth, accelerated urbanisation and economic development, the quantity of waste water generated is increasing globally. Mainly in low-income areas, a large proportion of the waste water is discharged directly in the environment. When the waste water is treated, the treatment plants may not remove certain pollutants that can have a negative impact on the people and ecosystem. ...

  • How a Specialized Automatic Control Valve Solved Flooding

    The Colombian area of Antioquia creates much of its clean power from hydropower plants along the Guadalupe River. The Guadalupe IV hydroelectric plant generates power with three vertical axis turbines that discharge water below the river level. To prevent flooding, however, the plant needed a solution that ensured the ejector ...

  • Monitoring hydrocarbons in Bilge water - Case study

    The Situation Various processes onboard ships, such as machinery wash-down, maintenance, and leakage, generate oily wastewater. This contaminated water flow collects in the bilge of the ship. Marine diesel, lubricating oils, grease, as well as other contaminants may be present in bilge water. The bilge water is discharged overboard, with oil and grease concentrations in the discharged ...

  • Advancements in Scaling Calculations and an in depth look at Antiscalant dosing for stressed waters and high recovery systems

    Abstract Over the past few decades the Reverse Osmosis (RO) industry has observed an increase in applications in challenging waters. Water sources that were never considered suitable for RO are now commonplace, including municipal waste streams, industrial waste, and even mining waste. Furthermore, regulatory restrictions, environmental obligations, solid waste expenses, and water supply ...

  • Building Energy Modeling 101: HVAC Design and Operation Use Case

    A great deal of energy use in buildings goes toward heating, ventilation, and air-conditioning (HVAC). In 2015, HVAC consumed 15.5 quads. The first step in reducing HVAC energy use is reducing heating and cooling load—i.e., the amount of heat that needs to be added to or removed from a building—typically by reducing heat from equipment and lighting; minimizing unnecessary ...

  • TOC analyzer for airports

    During winter, de-icing processes at airports necessitate storm water and de-icing water management. Especially due to adhesive (sticky) substances, strongly fluctuating concentrations and a lot of chemicals, the monitoring systems itself must be tailor-made to fight this water analysis challenge. LAR 's ...

  • Maintaining a pressure reducing valve: 5 things to check

    Like your car, your body and nearly every appliance you own, control valves require regular maintenance to continue working efficiently. However, due to budget and time constraints, we don’t always give our valves the TLC they need to perform at their best. Unfortunately, ignoring pressure reducing valves can mean serious ...

  • Articulated Concrete Blocks Provide Much Needed Protection for Your Pipeline

    One of the many ways that articulated concrete blocks can protect pipelines is by adding structural stability in areas that are particularly prone to erosion. This erosion is not the only type of hazard posed to your pipeline, though, and if you don’t have the proper protection in place, your pipeline could be susceptible to deterioration at the hands of these other threats as well: ...

  • 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. ...

  • 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 ...

  • 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 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 ...

  • 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 ...

  • 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 ...

  • Solar energy dissipation and temperature control by water and plants

    Ecosystems use solar energy for self-organisation and cool themselves by exporting entropy to the atmosphere as heat. These energy transformations are achieved through evapotranspiration, with plants as 'heat valves'. In this study, the dissipative process is demonstrated at sites in the Czech Republic and Belgium, using landscape temperature data from thermovision and satellite images. While ...
