WASTEWATER CONTAMINANT REMOVAL RESOURCES

• Moving Towards Effective Management Of Produced Water

  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).

• Sustainable Clarification In Food And Beverage Operations

  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.

• General Considerations For Treating Water For Difficult Pollutants

  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.

• Math Solutions Explained: Calculate Food-to-Microorganism (F-M) Ratio

  The food-to-microorganism (F-M) ratio is a process control numeric value advantageous to determine the proper number of microorganisms for the biological treatment process. The solution of calculating F-M ratio uses the influent volume of wastewater into an activated sludge system (flow MGD), incoming carbonaceous biochemical oxygen demand (CBOD) (mg/L) concentration into the aeration tank, mixed liquor volatile suspended solids (MLVSS) concentration (mg/L), and quantity (in gallons) of the respective aeration system.

• Best Practices For Decentralized Wastewater Treatment System Upgrades And Replacements

  Onsite wastewater treatment solutions are practical and popular, but changing regulations and conditions may require an update to operations.

• EPA Researchers Explore Technology To Destroy PFAS

  Per-and polyfluoroalkyl substances, otherwise known as PFAS, are a large group of human-made organic compounds with properties that make many of them toxic and persistent in the environment. PFAS have been manufactured and used since the 1940s in items such as fire-fighting foams, adhesives, cosmetics, paper products, and stain and water repellants. Until now, researchers have been unable to destroy PFAS in a way that has potential for larger scale use. 

• Bio-Organic Flocculant Treatment For Phosphorus Removal: A Zeoturb Case Study

  Regulating the discharge of phosphorus from industrial and municipal wastewater treatment plants is a primary factor in averting the eutrophication of surface water sources. Phosphorus is one of the key nutrients that contribute to this process in both lakes and natural waters. Its existence has caused major water quality issues such as the diminished recreational value of these surface waters, increased water treatment costs as well as the potentially lethal consequences of mycotoxins from algal growth.

• A New Spin On An Old Technology Yields Surprising Results

  A new advanced oxidation process has been born from a quest to find a more sustainable disinfection option for high water consumption applications, revolutionizing cooling water treatment and other operations with similar objectives, as well as entirely different fields like aquaculture, wastewater treatment, and animal drinking water applications.

• Industrial Wastewater Reuse: From Vision To Reality

  With the need for fresh water becoming ever more critical, an innovative treatment solution provides promise for cost-effective sustainability.

• 4 Key Factors Impacting Water Management In Industrial Operations

  The pressures of various risk factors, regulations, and responsibilities require a commitment to improve industrial water management.
