  1. The Role Of pH Measurement During Coagulation
    9/20/2018

    In the wastewater treatment industry, coagulation has become one of the most widespread processes for effectively separating contaminants and effluent. But coagulation is a complicated and sensitive process, one that alters the chemical balance of the wastewater in order to strip it of unwanted constituents. As in many such processes, pH plays a critical role, and treatment professionals must analyze it closely if they want to properly coagulate their product.

  2. Groundwater Replenishment System - Orange County, California (Case Study)
    6/15/2009

    The full-scale advanced treatment system takes filtered secondary effluent from the neighboring OCSD treatment plant and converts it to water that exceeds all drinking water quality standards. The 70 million gallon per day (MGD) system consists of microfiltration (MF), reverse osmosis (RO), and the TrojanUVPhox™ UV-oxidation/disinfection system.

  3. Clari-DAF® System Provides Effective TOC Removal For Cambridge WTP
    3/9/2015

    To ensure treated water complied with the most stringent drinking water standards, including the Environmental Protection Agency (EPA) Stage 2 Disinfectants and Disinfection Byproducts Rule (State 2 DBPR), the City of Cambridge, MA, WTP decided to implement a robust multibarrier treatment solution.

  4. Boron Removal By Thin Film Nanocomposite (TFN) Membranes
    3/13/2018

    Depletion of water supplies for potable and irrigation use has been a major problem in the world. Seawater desalination by reverse osmosis has become a common solution to address these demands. Using alternative sources of water requires implementation of increasingly stringent standards of water quality obtained by reverse osmosis processes, and boron is one of the most challenging contaminants in the final product.

  5. A More Efficient Approach To EPA Stage 2 DBP Compliance
    4/20/2018

    Everyone wants pathogen-free drinking water, and adding chlorine is a great way to get it. Unfortunately, the dirtier a water treatment plant (WTP)’s raw water inflow — in terms of natural organic matter (NOM) or microbial organisms — the more disinfection byproducts (DBPs) the chlorination process will generate in the form of trihalomethanes (THMs) and haloacetic acids (HAAs). Those DBPs increase the risk of non-compliance with the U.S. EPA’s Disinfectants and Disinfection Byproducts Rules. Choosing the right instrumentation to measure NOM through spectral absorption coefficients (SACs) can have a big impact on treatment strategies — in terms of both costs and compliance performance.

  6. Navajo Water Project Provides Clean Water To Native Americans
    3/15/2017

    It may seem farfetched, but the reality is that many Americans don’t have regular access to clean drinking water.

  7. Project Profile: Iron And Manganese Reduction, Village Of Corona, NM
    7/14/2010

    In the fall of 2008, AdEdge was selected by Village of Corona, NM to design, manufacture, and startup a water treatment system for the removal of iron and manganese. By Adedge Technologies Inc.

  8. WOTUS Appears Vulnerable To Trump Repeal
    2/15/2017

    On his way out of office, Barack Obama made a final effort to bolster the Waters of the United States rule (WOTUS), which has drawn controversy since it was issued in 2015.

  9. Groundwater Remediation - Stockton, California (Case Study)
    12/12/2012

    In the early 1990’s, the volatile organic compounds (VOCs) tetrachloroethylene (PCE), and trichloroethylene (TCE) were discovered in the vicinity of several city water supply wells near the city of Stockton, California.

  10. Upcoming Standards And Compliance Regarding Lead-Free Requirements
    9/18/2013

    Badger Meter has and will continue to manufacture and provide products that meet the requirements of current and future lead-free standards. This white paper discusses these changing industry needs both as they relate to Badger Meter products and to water utilities in general.
