The city of Buhl, Idaho, obtains all of its drinking water from groundwater sources through multiple wells. Prior to 2009, the city did not treat the groundwater but only added chlorine in the form of bulk 12.5% sodium hypochlorite to provide a disinfectant residual. A combination of factors including: changes in EPA and state DEQ regulatory requirements, growth of the residential population and growth of the industrial food processing customers forced the City to build a new water treatment plant to provide filtration to address the naturally occurring arsenic present in the groundwater.
When the Clean Water Act was enacted, one of the intentions of this legislation was to reduce the untreated industrial waste water burden on publically owned waste water treatment plants (POTW) so that industrial wastewater would only load the treatment plant to the same extent as ordinary household sanitary waste. Industrial facilities that generated process wastewater had to begin pre-treatment of the water before it could be returned to the local POTW.
For 30 years, the DEP diverted water from the abandoned Barnes and Tucker mines from the Susquehanna River basin for treatment in a system that discharged into the Ohio River watershed. BAMR sought a solution that would restore flow to the Susquehanna River at the request of the Susquehanna River Basin Commission.
Hayogev is a residential development in the rural area of Jezreel Valley, with 1000 homes, agricultural fields and dairy farms. Located in an open field next to small farms, the local treatment facility handles wastewater from HaYogev and Midrach Oz. The customer was looking for a localized wastewater treatment solution to replace the existing pond system, which faced difficulties in treating the wastewater due to high levels of nutrients. A new state-level regulation concerning reclaimed water required the wastewater treatment plant (WWTP) operator to reduce the nutrients in the effluent stream. The solution had to be odorless and quiet, have low power consumption, and use the existing pond and structure.
A state-of-the-art 695-MW power generation facility was recently installed in the Northeastern U.S. to serve the country’s highest demand market. Its innovative power generation technologies, emissions control systems and process efficiencies make it one of the cleanest, most efficient and technologically advanced supercritical pulverized coal (SPC) power plants in the U.S.
The residents and industries of Providenciales Island are completely dependent on fresh water produced by a single desalination plant. In 2007, ITT Flowtronex was hired to replace the plant’s overworked pumping system and add a booster pumping station to the distribution system. One of the challenges they faced in designing controls for the system was how to maintain the public water supply while the island’s undersized ground water storage tanks were removed and replaced with a large single tank in the same location, a three to four month process.

Refineries are among the major consumers of water that has both process and non-process origins. The average refinery requires 2.5 gallons of water for every gallon of crude oil processed. Depending on the type of crude oil, composition of condensate and treatment processes, the characteristics of refinery wastewater varies widely. The design and operation of modern refinery wastewater treatment plants are challenging and are driven by technology. This article will highlight the most common types of waste streams in a refinery and suitable wastewater treatment strategies.
Upstream oil/gas production companies around the globe depend on mud logging service companies to analyze mud samples that help them maintain the correct direction for their drilling field operations. In mud logging, samples of rock cuttings from bore holes are brought to the surface by recirculating drilling media (mud) for analysis by a mobile laboratory to determine the lithology and fluid content of the sample.
A U.S.-based pulp and paper manufacturer required high purity process and boiler feed water. It was using water from a local well and treating it with a 150 gpm conventional RO system operating at 75% recovery, but this was creating 50 gpm of wastewater – over 26 million gallons per year.
Latin America and the Caribbean have rich potential to replace fossil fuels with green energy as technology delivers profitable and environmentally friendly alternative sources of heat and electricity generation.
200-acre Monmouth Park Racetrack in Oceanport, NJ, is supported by a series of barns and other support facilities that house in excess of 500 horses during track operations. In the mid-1990s the New Jersey Sports and Exposition Authority (NJSEA) constructed facilities to collect horse wash water and first flush stormwater runoff for conveyance to the Two Rivers Water Reclamation Authority (TRWRA), a wastewater treatment facility located in Monmouth Beach.
The Aqua Caiman™ represents the next generation of multi-rake mechanical bar screens. In designing the screen, Parkson combined over 40 years of experience working on thousands of in-channel screen installations with in-depth market and engineering research. This allowed us to better understand the weaknesses of existing multi-rake and articulating rake screens.
This video provides a simple overview of the screen’s creation, function, features and benefits. From the beginning, Parkson engineers took it a step further by working with a leading design firm to rethink the industry standard step style screen from the ground up. They reviewed current offerings on the market and improved upon the common weak points. The result is the most durable escalating screen out there – the Aqua Rhino.
Whatever the setting, and however contaminated your water, BakerCorp has a solution. That's the message shared by Mehrzad Emanuel (Vice President, Filtration), Doug Herber (Vice President, Water Treatment Technology), and Bruce Lesikar (Director of Engineering) in this video presentation from WEFTEC, where they discuss BakerCorp's electrocoagulation technology and its mobile treatment platform with Water Online Chief Editor Kevin Westerling.
Water from cooling towers attracts and absorbs airborne contaminants on a continuous basis. Typically, 85% of suspended solids in cooling water and hot water loops are smaller than 5 microns. Scientific studies have shown that these small particles (5 microns and less) are the adherent contaminants fouling the water loop and process cooling system.
