  • Detect Leaks and Analyze Water Consumption with WaterSignal

    Did you know it will cost an estimated $1 trillion over the next 25 years to upgrade the nation’s water system to run more efficiently? While part of the problem is fragile, hundred-year-old water mains, it also falls on property owners to ensure they are doing their part to save water — for both the environment and their wallets. But how? ...

  • Comparing Evaporative technologies for the Recycling of produced Water

    Both multi-stage and MVR evaporators are capable of producing distilled quality water from produced water.  Distilled water quality ranges from 100 to 500 ppm TDS depending upon the initial TDS of the produced water and the level of concentration of bottoms (waste) obtained. Typical systems are capable of attaining final concentrations ranging from 270,000 ppm to 350,000 ppm TDS.  The ...

  • Evaporator saves electroplater millions in disposal costs

    The Facility The AK Steel Middletown Works plates zinc nickel alloy onto steel strip. They started up their first plating line in 1991 and expanded from twentyone to thirty-two cells in 1995. The Problem In order to maximize line speed and thus the production, the strip needed to be rinsed immediately after plating. The rinse water diluted electrolyte ...

  • Evaporator reduces wastewater volume for dakota gasification

    Evaporator integral to stringent zero liquid discharge (zld) waste requirements American Natural Gas (ANG) developed a coal gasification project in Beulah, North Dakota in the early 1980’s to produce pipeline gas and various other products. Basin Electric, the local utility, acquired the plant in 1988 and renamed it Dakota Gasification. The Problem ...

  • Gettysburg hospital addresses ailing evaporative coolers

    WellSpan Gettysburg Hospital was looking to modernize mechanical systems to ensure reliability of critical patient-care functions. Constructed in 1921, WellSpan Gettysburg Hospital in Gettysburg, Pa., has undergone a number of changes over the years. According to Joe Lehigh of the facility’s engineering team, the most recent were made chiefly to improve hospital operations. “The key ...

  • Extension of an existing model for soil water evaporation and redistribution under high water content conditions

    Most crop, hydrology, and water quality models require the simulation of evaporation from the soil surface. A model developed by J.T. Ritchie in 1972 provides useful algorithms for estimating soil evaporation, but it does not calculate the soil water redistribution resulting from evaporation. A physically-based model using diffusion theory, described previously by Suleiman and Ritchie in 2003, ...

  • Evaporation stills fear of chelates and heavy metals - Reliable treatment of rinsing water from zinc

    Zinc nickel plating is the state of the art corrosion protection method for stainless steel. In the automotive industry as well as in the mining and in the production of windmills it replaces old processes like alkaline zinc plating for instance. The electrolytes used in zinc nickelplating contain highly concentrated chelating agents. This makes treatment of such industrial wastewater ...

  • Greenhouse based desalination for brackish water management using bittern evaporative cooling technique

    The Arab region is characterized by arid and semi-arid conditions with very limited renewable water resources. Most of the surface water comes from transboundary streams and most of the groundwater resources are fossil in nature. Water quality degradation and excessive use of pesticides and herbicides in agriculture pose severe environmental and health risks. The underlying research is a joint ...

  • Evaporator concentrates brine pond for about 1 cent per gallon

    The Facility Eagle-Picher Industries has an 8-acre hazardous waste surface impoundment pond at its Electro-Optics Division plant in Quapaw, Oklahoma. The Problem By the time Eagle-Picher contacted Aqua-Chem ICD, the impoundment pond had been in use for more than 20 years and contained more than 5 million gallons. Environmental regulation required the plant ...

  • Evaporator Limits Boron to 5 PPM at award-winning chemical plant

    Problem: The biggest challenge confronting Rohm & Haas Corp. in building a wastewater plant for its chemical facility in Elma, Wash., was meeting Washington State Dept. of Ecology limitations on boron of 5 ppm. The Elma plant manufactures sodium borohydride, a versatile chemical used in a variety of applications ranging from the generation of sodium hydrosulfite for reductive bleaching of ...

  • Thermal deoilers - Thermal deoiling of evaporator coils for air conditioners

    The Problem A major Air Conditioning company was mandated to have an alternate technology for degreasing evaporator fins. They had, until recently, been deoiling metal parts in a conveyorized solvent based vapor degreasing line, but the state environmental agency mandated that the line be shut down on a certain date due to the excessive water and air pollution it generated. The company ...

  • The role of soil moisture accounting in estimation of soil evaporation and transpiration

    In this study, we explore how the differences in soil moisture accounting affect the estimation of actual soil evaporation (E) and transpiration (T). The main objective is, therefore, a comparative assessment of a vapor flux estimation method which has explicit soil moisture accounting, against a vapor flux estimation method that uses satellite observed soil moisture data. ...
