WASTEWATER FEATURES, INSIGHTS AND ANALYSIS

  • C3500™D UV Wastewater Disinfection

    UV disinfection is a physical process that applies only UV light to the water to render pathogens harmless to humans. It can be used to replace or reduce the traditional use of chlorine as a disinfectant. Chlorine has been shown to have significant environmental impact via toxicity to aquatic life and formation of disinfection by-products (DBPs). Additionally, it presents safety risks to plant operators that handle and store the chemical.

  • Neutralizing Dissolved Solids Aeration Concerns
    Neutralizing Dissolved Solids Aeration Concerns

    The presence of dissolved solids presents both physical and financial challenges for aeration diffusers in any wastewater treatment operation and can be particularly problematic in high-concentration industrial and food-processing applications. Here are some warning signs, insights, and solutions for coping with conditions that can lead to excessive dissolved solids accumulation.

  • How To Use ATP And DNA In A Wastewater Nitrification Monitoring Plan
    How To Use ATP And DNA In A Wastewater Nitrification Monitoring Plan

    Ammonia removal is a key metric for assessing wastewater treatment facility performance. This is because ammonia contributes to aquatic life toxicity. Furthermore, nitrogen, along with phosphorus, is a driver of receiving water eutrophication. Eutrophication, which simply is an over-enrichment of nutrients, can be detrimental to environmental and public health. It can result in harmful algae blooms, dissolved oxygen depletion, fish kills, and other damaging impacts.

    A New Platform For Safer Surface-Aerator Maintenance

    With so many different safety concerns — government-mandated or self-imposed — municipal and industrial wastewater treatment operators have a lot on their plates. Maintaining aerators used in open-basin treatment applications is just one source of those safety concerns. That is why a new approach to safeguarding worker well-being in the process of aerator maintenance activities is worth a closer look.

  • 4 Benefits Of Utilizing Reverse Osmosis Wastewater Treatment For Reuse
    4 Benefits Of Utilizing Reverse Osmosis Wastewater Treatment For Reuse

    When a municipality or business wants to reuse their wastewater, some applications require more treatment than others due to the quality of the wastewater. Many standard wastewater treatment systems consist of pretreatment, primary treatment, and secondary treatment stages. By the end of the secondary stage, a majority of the pollutants, solids, organics, inorganics, and metals have been removed or reduced. This is where reverse osmosis wastewater treatment can be utilized in a third stage process.

  • Beware Of Problematic Wastewater Aeration Additives
    Beware Of Problematic Wastewater Aeration Additives

    Too much of a good thing can create new problems as quickly as it resolves old ones. Maintaining a proper balance of antifoaming agents and polymer additives is critical for sustaining the appropriate air bubble size and distribution needed to achieve dissolved oxygen (DO) requirements for neutralizing high biochemical oxygen demand (BOD) in many industrial and food processing wastewater applications.

  • Making The Best Of A Bad O<sub>2</sub> Situation
    Making The Best Of A Bad O2 Situation

    A balanced wastewater process is a beautiful thing — plenty of biochemical oxygen demand (BOD), plenty of O2, and all those hungry little microbes are fat and happy. But what can be done when dissolved oxygen (DO) takes a nosedive and there’s not enough O2 to satisfy industrial and food processing BOD? Here are some preparations to consider before wastewater treatment goes completely out of whack.
