Preventing Backflow
Preventing Backflow
There are lots of applications in the water and wastewater industry that need backflow prevention. Stormwater drainage systems are a perfect example.  As Mike Duer, Chief Engineer with Red Valve Company explains in this Water Online Radio interview, “water will backflow through the drainage pipe at high tide, come up through the inlets and cause flooding.”  Continue Reading..
SUEZ Looks To Reduce Greenhouse Gas Emissions From Water Sector
Eric Gernath, CEO of Suez North America, sees a huge correlation between climate change and water. In what the Company calls the circular revolution, Gernath’s mission is to reduce greenhouse gas by recovering, reusing and recycling water as well as minimizing energy consumed in water and wastewater treatment.  Continue Reading..
Finer Screenings Requires Headworks Innovation
Finer Screenings Requires Headworks Innovation
Over the past ten years, the trend in headworks has been to finer and finer screenings. As expensive to replace downstream processes are adopted, operators are looking to minimize fouling by screening out more trash. Examples of such processes would be membrane bioreactors (MBRs) and moving bed biofilm reactors (MBBRs), which are highly sensitive to trash.  Continue Reading..
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...  Continue Reading..
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.”  Continue Reading..
Smart Sensors Have Finally Arrived
The heavy-duty, industrial strength of Aquametrix probes have made them ideal for wastewater applications. But as Mark Spencer, President of Water Analytics and the manufacturer for Aquametrix, points out in this Water Online Radio interview, they are also being accepted by a growing industrial audience.  Continue Reading..
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...  Continue Reading..
Three Largest Challenges With Wastewater Lagoons
Three Largest Challenges With Wastewater Lagoons
When it comes to wastewater lagoons, there are three main challenges that operators run into. The first, similar to other parts of the nation’s wastewater treatment infrastructure, is age. The second is compliance with new EPA ammonia, nitrogen and phosphorus limits which many lagoon plants weren’t designed to deal with. And the third is expansion as communities grow and need additional capacity.  Continue Reading..
