Regulations and Legislation Features, Insights, & Analysis

  1. Liquid Level/Interface Monitoring In Flocculant/Sludge Control

    Precisely measuring and controlling the mixture of wastewater effluent, flocculants, and sludge is essential to efficient water treatment. The level/interface instruments that support the process liquid measurements must be capable of distinguishing between liquids with varying properties in order to detect the levels where the different liquids interface in the pond or tank.

  2. Lessons Learned From Flint

    We all hope that the Flint Water Crisis – where cost-cutting measures led to the drinking water supply to become severely tainted with lead – was an isolated incident. However, it is not impossible that a similar event could happen again, especially in a similarly  desperate city with limited financial resources. Here are a few key points that should be considered to avoid repeating such a tragedy.

  3. The Real History Of The First Thanksgiving

    Water supplies remain our most valuable and necessary resource. Overused and often contaminated throughout most of history, water was no less of a concern back in the 1600s when the Pilgrims landed at Plymouth Rock than it is for us today.

  4. Indirect Potable Reuse With UV-Oxidation - Big Spring, Texas (Case Study)

    In an effort to reduce reliance on dwindling surface and groundwater supplies in Texas, the Colorado River Municipal Water District (CRMWD) constructed a new Raw Water Production Facility (RWPF) in Big Spring. Big Spring is a 27,000-member community located in West Texas approximately 300 miles west of Dallas. This RWPF treats secondary wastewater to a standard that allows it to be re-introduced directly into the raw water supply for the water treatment plants of Big Spring, Odessa, and other communities in the region.

  5. CA 71 With Ammonium And Nitrate Measurement
    Metro Waste Reclamation District is one of the largest wastewater treatment plants between the Mississippi River and the west coast. Treated water is discharged into the South Platte River, and contributes 90% of the river’s annual flow at the point of discharge.
  6. X-Ray Inspection Of Unpackaged Almonds

    Almond harvesting runs the risk of including foreign objects in processing lines. Implementing an effective inspection system is critical to brand protection, food safety, and bottom-line efficiency.

  7. Thermal Mass Flow Meters For Greenhouse Gas Emissions Monitoring

    The U.S. EPA sets national ambient air quality and greenhouse gas emission standards to ensure public health. Thermal mass flow meters deliver a direct reading of mass flow rate of natural gas and other fuel gases — without temperature and pressure compensation — and provide a simple, reliable and cost-effective method for tracking and reporting fuel consumption.

  8. ETS-UV™ For Drinking Water Disinfection Product Summary

    ETS has developed a range of drinking water UV systems that comply with the requirements of the US EPA Design Guidance Manual and have been independently validated to demonstrate performance under a variety of operating conditions. The systems are modeled using CFD and FEA emulation tools, which are continuously and iteratively improved following bioassay, routinely undertaken with a variety of surrogate organisms such as B. Subtilis, T1, and MS2 phage.

  9. Hydro-Guard Advanced Flushing System Simplifies Operations, Increases Water Quality And Saves Treatment Expenses

    Birmingham Water Works Board (BWWB), Birmingham, Alabama has consistently achieved the rating of the number five water system in the United States for water quality.  BWWB’s potable water distribution system (WDS) serves 600,000 people with a daily average use of 100 million gallons (378 million liters) of water, received from nearby lakes and rivers. The system includes 51 water storage tanks, nearly 4,000 miles (6,437 km) of pipe, over 13,000 fire hydrants and over 200,000 service connections.

  10. PPM-Level HCl Measurements From Cement Kilns And Waste Incinerators By FTIR Spectroscopy
    Fourier transform infrared (FTIR) spectroscopy is an accepted and well-known technique by the EPA to measure hydrogen chloride (HCl). Over the past 10 years, HCl by FTIR has been utilized successfully at many cement kilns and other incineration technologies using EPA Method 321 or 301.
