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.
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.
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.”
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.
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.
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.
One way to think about offsetting water rate increases is to reuse the water being consumed. For example, instead of paying $100 a quarter and using the water flowing out of faucets just once, what if you as a homeowner could treat that wastewater on site and reuse it to irrigate the lawn, wash the car, or flush the toilets?
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.
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.
As municipalities look to make their water and wastewater treatment equipment run longer with fewer operational staff on payroll to maintain the equipment, having a reliable aftermarket parts and service provider becomes essential.
