Wastewater Contaminant Removal Podcasts

  1. Peracetic Acid (PAA) Disinfection Is Up For The Challenge 10/20/2017

    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.

  2. Different Wastewaters Require Different Decentralized Solutions 10/20/2017

    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.

  3. De Nora Doubles Down On Innovation 12/14/2016

    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.

  4. Decentralized Membrane Treatment Technology 11/7/2016

    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.

  5. Polymer Activation And Onsite Hypochlorite Generation 11/3/2016

    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.”

  6. Modular Dissolved Air Flotation Systems Ideal For Treating Suspended Solids In High Flows 11/2/2016

    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.

  7. PAA And UV Pair Up To Improve Disinfection Performance 10/26/2016

    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.

  8. The Benefits Of Closed-Channel UV Over Open-Channel Disinfection 10/19/2016

    The era of dumping waste into rivers is almost over. So says Jon McClean, Chief Technical Officer with ETS-UV, an Evoqua brand. McClean who has been working in UV water treatment for over 30 years recently sat down with Water Online Radio to discuss the growth of water reuse and specifically UV’s role in water reclamation.

  9. Fuzzy Filter Uses Compression In Advanced Primary Treatment 11/25/2015

    Advanced primary treatment reduces or eliminates the solids load or organic carbon out of the waste stream. By doing so, a wastewater plant can decrease aeration power and avoid the need to expand its treatment basin size. The removed solids can also be moved to a digester to produce energy.

  10. Benefits Of Walnut Shell Backwashable Media Filters 11/23/2015

    Filtra Systems Company developed the walnut shell filter about 40 years ago. One of the attractions of walnut shell is how well it can handle oil. When oil mixes together with sand, it essentially becomes asphalt. With walnut shell, the oil is coalesced and then, when it’s backwashed, the oil can be released from the shell.
