OKLAHOMA CITY, Okla. (Jan. 13, 2015) – World Water Works, Inc. (WWW), a designer and manufacturer of wastewater treatment solutions, has been selected to provide its Ideal MBBR-DAF technology to Hopewell Regional Wastewater Treatment Facility (HRWTF), a 27 million gallons per day (MGD) facility. This selection came through a design/build public/private partnership between the City of Hopewell and the team of HDR Engineering (HDR), PC Construction (PC), Heyward Inc. and World Water Works, Inc. The combination of the Moving Bed Biofilm Reactor (MBBR) and Dissolved Air Flotation (DAF) technologies is well suited for this situation and will bring the total nitrogen (TN) waste load of the HRWTF into compliance with local regulations. HRWTF has a unique situation where the source of more than 80 percent of its wastewater comes from industry some of which contains known toxins to Ammonia Oxidizing Bacteria (AOBs) and Nitrite Oxidizing Bacteria (NOBs). AOBs and NOBs are responsible for the traditional nitrification / denitrification process of removing nitrogen from wastewater. To solve the problem, HRWTF conducted an extensive evaluation and pilot treatability study of various technologies including WWW’s advanced MBBR coupled to a high rate DAF system, the Ideal MBBR-DAF system. After over six months of pilot testing, Ideal MBBR-DAF system by consistently bringing TN levels of the facility to the future targets while being very robust against the harder to degrade industrial wastewater sources being treated. Further, WWW and HDR developed a creative design to reduce capex and provide a robust solution. To provide a timely and cost effective solution to HRWTF; HDR, PC, Heyward and WWW teamed together to present a public/private partnership (PPP) option. HRWTF evaluated this option thoroughly and through independent parties and found that the option not only offered the ability to implement the project faster, but also at a substantially lower cost than the traditional design-bid-build path. “This PPP is a win-win-win,” explains Daniel Dair, Technical Manager at WWW. “HRWTF gets a state of the art system with a binding performance guarantee from one source, the price is not only lower than anticipated, it is also guaranteed, and the local water ways and Chesapeake Bay win with better water quality sooner.” The project is in full swing and is expected to be completed by 2016. World Water Works is a manufacturer of specialized process and wastewater treatment technologies. Hopewell Regional Wastewater Treatment Facility is a secondary wastewater treatment plant from local industries and domestic sources.
