Wastewater Contaminant Removal Podcasts

  1. Drumming Up Chemical Injection

    The operating ranges for chemical injection need to be large because of the variability of flow in many treatment operations. As Bill McDowell, Vice President of Operations with Blue White Industries explains in this Water Talk interview, “You might be down to as low as 5 or 10 milliliters a minute and then one hour later; you might need to pump 15 gallons a minute out of the same pump and through the same sensor.”

  2. Decentralization Grows With Worldwide Property Development Expansion

    One of the trends in water and wastewater treatment over the past decade has been a growing demand for decentralized systems. Water Talk recently caught up with Nii Mensah, General Manager of Fluence USA, to learn more about the solutions that the new company (formed by the merger of RWL Water and Emefcy) is bringing to market to address communities’ treatment needs

  3. Converting Wastewater Treatment Facilities Into Botanical Gardens

    Municipal wastewater treatment has traditionally taken place as far away from the populace as possible. But as people flock to cities and encroach ever closer on these facilities, the practice of extending ever further out becomes impractical and expensive. And as water becomes scarcer, cities the world over are looking at recycling wastewater from their citizenry closer to home.

  4. Peracetic Acid (PAA) Disinfection Is Up For The Challenge

    The primary consideration for evaluating disinfection alternatives has to be permit compliance. But as Sarah Stewart, Associate and Senior Project Manager with CDM Smith explains in this Water Talk interview, contact time, high color, nitrates, industrial loads and many other factors all play a role in selecting the most practical and cost effect disinfection solution for your facility.

  5. Different Wastewaters Require Different Decentralized Solutions

    When we think decentralization, we often think of smaller and smaller systems, supporting a single-family home or business. So it was interesting to sit down with Bob Rebori, President of Bio-Microbics recently and learn that the Company is being asked to build larger decentralized systems to support a variety of commercial applications.

  6. De Nora Doubles Down On Innovation

    With 29 locations, 1,600 employees and research facilities in Japan, Italy and the United States, DeNora is one of the largest disinfection and filtration companies in the world. As Gary Lohse, Regional Sales Manager for De Nora, explains in this Water Online Radio interview, the acquisition of the former Severn Trent manufacturing division coupled with De Nora’s product innovation strength is driving enhancements to some of the most respected brands in the water industry.

  7. Decentralized Membrane Treatment Technology

    In the early 90s, Bio-Microbics introduced membrane treatment technology, traditionally used in drinking water treatment plants, to the decentralized treatment market. In this Water Online Radio interview, Jennifer Cisneros, Director of Marketing for Bio-Microbics and Chair of the National Onsite Wastewater Recycling Association’s Marketing Committee, discusses the use of the onsite technology at an oyster bar where Total Kjeldahl Nitrogen (TKN) was about three times the level of ammonia.

  8. Polymer Activation And Onsite Hypochlorite Generation

    Polymer activation through proper hydration of the polymer particle is critical in water clarification or sludge dewatering applications. According to Jeff Rhodes, Vice President of Commercial Development for UGSI Solutions, “the key is to have a high energy zone at the moment of initial welding, when the polymer and the water come together.”

  9. Modular Dissolved Air Flotation Systems Ideal For Treating Suspended Solids In High Flows

    Dissolved air flotation systems are ideal for removing suspended solids and emulsified oils from industrial wastewater streams because they work at high flows and can process high concentrations of contaminants. As Richard Newman, Director of Sales for SUEZ’s Gulf Coast Services, points out in this Water Online Radio interview, the treatment system is ideal for refineries and pulp and paper plants where suspended solids are not water soluble but emulsified.

  10. PAA And UV Pair Up To Improve Disinfection Performance

    Peracetic acid (PAA)-based disinfection is growing in the US, both as a standalone disinfection method and in conjunction with other applications such as UV. Water Online Radio sat down with John Maziuk, Technical Development Manager with Solvay Chemicals to understand why.
