Bord na Móna Environmental Products U.S. Inc., the American market subsidiary of the $550-million Bord na Móna group based in Dublin, Ireland, introduced three new wastewater treatment solutions and new odor/VOC control technologies at WEFTEC.08 in Chicago, Ill.
The company said it was significantly expanding its commitment to the U.S. market through the ongoing development of environmentally focused products that reduce energy and chemical demand, incorporate recycled materials and provide water reuse solutions.
“It’s time to forge a new contract with nature,” said Shane Keaney, president of Bord na Móna Environmental Products U.S. Inc., based in Greensboro, N.C. “All of us have a responsibility to protect the environment we live in. The solutions being introduced today reflect our global commitment to offer sustainable thinking about wastewater pollution, water conservation, and clean air technologies that translates directly into high performance, cost effective treatment solutions for municipalities, communities, and homeowners.”
The company’s new PuraM Membrane Bio-Reactor (MBR) system is engineered specifically for the decentralized municipal, community and commercial wastewater treatment market with an emphasis on reliability, reduced operational input, ease of maintenance and less complexity than comparable systems.
The MBR system is based on flat plate ultra-filtration membrane technology assembled into stainless steel membrane cassettes. The cassette consists of a unique integral dedicated air diffuser assembly that eliminates the need for back-pulsing or frequent chemical cleaning. The system does not require permeate pumps or any site installed chemical dosing system while achieving a typical time between recovery cleans of approximately 12 months, significantly better than comparable systems.
The new PuraMAX Moving-Bed Biological Reactor (MBBR) is designed to achieve a high-quality effluent at low cost, all within a small overall footprint. The system is ideal for high strength and pre-treatment applications.
The new PuraSAF Submerged Aerated Filter is an attached growth activated sludge process that provides a cost effective, low energy pre-engineered wastewater treatment solution that is simple to operate and maintain. Specially designed, recycled plastic media act as biomass carriers and provide a large surface area for bacteria to attach. This allows the system to have a much smaller footprint and better oxygen transfer efficiency than traditional activated-sludge processes, saving capital and operating costs through lower process air requirements. The filter normally operates in an upflow packed bed configuration that is readily fluidized for cleaning and desludging.
Finally, the new MÓNASHELL Biofiltration System is a sustainable, low operating cost alternative to traditional carbon adsorption or chemical scrubbing. The reuse of waste shells as media maintains a neutral pH, allowing for highly effective biological treatment of odorous sulfur compounds in wastewater and industrial airstreams without the use of chemicals. The system is designed to deliver significant, environmentally responsible benefits for wastewater pumping stations, wastewater treatment works, sludge-handling and treatment processors, municipal solid waste and composting centers, as well as various industrial facilities.
