• 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.

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

  • 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. 

  • 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 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.

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

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

  • The DE NORA TETRA Modular DeepBed Filter (MDBF) Plant is an established tertiary wastewater filtration technology for the UK municipal water market to remove total suspended solids (TSS) before final effluent is discharged to a water course.

  • The Wastewater Treatment Plant of Barstow, California (USA), sits in a challenging geographic and demographic position on a straight line between Los Angeles and Las Vegas. Operating a biological nutrient removal system, the plant treats 2.1 million gallons of water per day and discharges into percolation ponds. Kody Tompkins is the Chief Plant Operator of the facility.

  • The benefits of the facultative membrane bioreactor (FMBR) are examined, along with results of a pilot demonstration project to further prove efficacy.


  • GWT Specialized Electrocoagulation System

    GWT electrocoagulation (EC) technology has become a valuable solution in the treatment of water and wastewater due to its ability to remove contaminants that are generally more difficult to remove by filtration or chemical treatment systems, such as emulsified oil, silica, total petroleum hydrocarbons, refractory organics, suspended solids, and heavy metals.

  • Schreiber Grit & Grease

    Schreiber's Grit & Grease removal system is  unique system designed to remove both grit and grease in a common structure. The rectangular design provides efficient removal over a wide range of flows. The deeper chamber is for the settling of grit and in the other chamber grease floats to the surface for removal. The operation is automated with a PLC control for maximum operating efficiency.
