  • Senix AirWire Tracks USGS River Data

    Since 2001, the United States Geological Survey (USGS) has collected water-resources data in all 50 states and beyond. The organization has studied groundwater, surface water, water quality and water use through initiatives such as the National Streamflow Information Program (NSIP), which used...
  • Check Valves Assembled to Order When You Need Them

    When a check valve breaks or malfunctions, it may cause an entire system to break down. A new, high-quality check valve is needed—and it’s needed immediately. While a company may have a backup valve they can use in the meantime, it’s still necessary to get the replacement quickly. Check-All...
  • Making it clear – the water quality standards of NSF/ANSI 61 and 372

    To make the products safe for water distribution there must be protective barrier material, joining, and sealing materials. These materials will ensure that the water remains free from any contaminates that may be present on or in the metal, paint, gaskets, lubricants, etc. NSF/ANSI has...
  • systems description

    Microfiltration/Ultrafiltration MF/UF systems are used to remove suspended solids (TSS) and high molecular solutes, while water and low molecular weight solutes pass through. Membranes are defined by the molecular weight cut-off (MWCO). Nanofiltration NF is very similar to that of RO, with...
  • Sewage Lift Stations - Reducing Maintenance Costs

    Provide Continuous Monitoring and Reduce Maintenance Costs in Sewage Lift Stations. The Level Transmitter is a small but vital component in a Sewage Lift or Pump Station to maintain system integrity and avoid unwanted spillage.
  • Data Logger vs DAQ

    Key Differences Between Data Logging and Data Acquisition What is the difference between a Data Logger vs DAQ System? A data logger is a type of data acquisition system, but a data acquisition system is not necessarily a datalogger. There are several key functional differences in how the market...
  • 18 Programmable Settings You Need In An Ultrasonic Sensor

    Like anything else, there are both cheap and good quality ultrasonic sensors out there. Besides good manufacturing, one of the major differences between a good sensor and everything else is programmability. While non-configurable sensors might seem like a bargain, the advantages of programmable...
  • Cooling Systems 101

    If you need help determining which type of cooling system is correct for your application.
  • ChlorTainer - Preference for Chlorine Gas for Disinfection

    ChlorTainer is a high-pressure containment vessel into which a 1-Ton or 150-lb chlorine gas cylinder is processed. If the cylinder should leak, chlorine gas is contained within the vessel and processed at a normal rate. All of the chlorine gas is used, and no hazardous waste is generated.The...
  • How to Select the Right Water Filtration Solution

    Water filtration has been present throughout recorded human history. There are records of water filtration as far back as 2000 BC. Human bodies consist of 70% water and therefore need water — potable water — to sustain them. Historically, civilizations were constructed around bodies of water,...
  • Removing Dissolved Copper in Wastewater Treatment Plants

    How do you meet your dissolved copper discharge limit if it is 1.6 ppb, 3.1 ppb or 6.1 ppb? What is the cost to achieve these limits? Which treatment is cost effective? Is deionization, Reverse Osmosis or chemical precipitation the best alternative to low level of dissolved copper in a...
  • DCS vs. PLC: Choosing the Right Platform

    This white paper provides general guidelines and highlights key considerations when choosing a control system platform (DCS or PLC).
  • Flood Improvement and LID Modeling Using XPSWMM — a Case Study
