Wastewater Contaminant Removal Resources

  1. Orbal® System for Biological Nutrient Removal 1/30/2023

    Discover how a fast-growing community's new WWTP meets new tighter limits on ammonia, phosphorus, and nitrogen for future growth.

  2. Demand For Mobile Water Treatment Systems Is Expected To Grow 1/23/2023

    The North American mobile water treatment market was valued at $725 million in 2022. The market is expected to witness a single-digit growth rate during the forecast period, driven by the provisional need for a treatment system in case of plant downtime, facility maintenance, emergencies, or to meet regulatory requirements for effluent discharge. The key challenges in this market include intense competition, the COVID-19 pandemic, and economic volatility.

  3. Doing More With Less: Densified Activated Sludge (DAS) Systems For Water Resource Recovery Facilities 1/11/2023

    As wastewater treatment plants — or water resource recovery facilities (WRRFs), more preferably termed — continue to strive for efficiency, DAS has emerged as a space-saving intensification solution.

  4. How To Lower BOD In Wastewater 11/8/2022
    Reducing biochemical oxygen demand (BOD) in wastewater is a key challenge for treatment facilities, but some solutions can help. BOD is a crucial factor in monitoring water quality and safety, and achieving a low BOD is one of the top goals of any plant.
  5. When Decentralized Wastewater Is The Wise Choice 11/3/2022

    Centralized wastewater treatment systems have been the dominant — and extremely effective — choice for pollution control historically, but onsite could prove right in many cases today.

  6. Bubble, Bubble Toil And Trouble 10/31/2022

    With this being Halloween, I figured I would paraphrase the Song of the Witches from Shakespeare's Macbeth to continue my reporting on how bubble technology can play a major role in water treatment applications.

  7. Decentralized Wastewater Treatment — A Closer Analysis 10/5/2022

    Are you looking for an effective and innovative decentralized wastewater treatment solution for your commercial/industrial facility or community?

  8. Moving Towards Effective Management Of Produced Water 8/18/2022

    You cannot produce oil without water, because water is present naturally in both onshore and offshore oil reservoirs. This naturally occurring water is called produced water. Produced water has a simple to complex composition that is variable, and it is considered as a mixture of dissolved and particulate organic and inorganic chemicals (Al-Ghouti et al. 2019) with an average of 7 to 10 barrels of produced water being generated for each barrel of oil during the course of an operation (Guerra, Dahm, and Dundorf 2011).

  9. Sustainable Clarification In Food And Beverage Operations 8/5/2022

    Companies within the food & beverage industry generate significant quantities of wastewater each day. For example, a 16 oz. can of beer is about 90-95% water; however, to make that can, beer producers utilize approximately 7 times this quantity. About 2/3 to 3/4 of the water is typically discharged as wastewater to a municipal sewer system.

  10. General Considerations For Treating Water For Difficult Pollutants 7/6/2022

    As a matter of course, we normally consider removing various pollutants by direct means such as microbial degradation, chemical treatment that results in a change in the pollutant in some way that is to our benefit (usually oxidation/reduction), or in some manner that results in products easily removed such as gases, various precipitants, or even degraded compounds that are no longer toxic. Some methods are entirely physical, such as centrifugation and filtration, even settling; others are semi-hybrid measures, such as exploitation of various adsorption criteria that do not require chemical change.
