Improved Pump And Seal Reliability When And Where It Really Counts
The City of Chester, IL was getting only about 6 months life out of the mechanical seals in their former non-clog lift station pumps. While replacing seals twice per year was difficult and expensive, the more serious problem occurred when the seals failed with the Mississippi River at flood stage and with the sealed lift station underwater.
Clari-DAF Pretreatment System Reduces Chemical Consumption, Doubles Treatment Capacity
Together, two water treatment plants in Boulder, CO, have the capacity to treat 55 million gallons per day (MGD). When severe drought conditions restricted the source water supply of the Betasso WTP, the city decided to expand the capacity of the Boulder Reservoir Water Treatment Plant (WTP).
Dissolved Air Flotation Technology Nearly Doubles Treatment Capacity
Faced with a tight capital budget, a city in British Columbia required a new design for a water treatment plant capable of a maximum daily water production of 21 MPG during peak demand periods, with an ultimate demand of 29 MGD.
How To Get A One-Year Payback On Retrofit Chopper Pumps For Your Packaged Lift Station
The Independence Hill Conservancy District's Taney Lift Station was having continuous problems with wipes, swiffers, and plastics deposited in the incoming lines, which then broke loose in storms and overwhelmed the old non-clog pumps.
Treatment Plant Utilizes UV Disinfection To Exceed Environmental Regulations
The city of Carmel, IN, located north of Indianapolis, owns and operates a WWTP that treats sanitary waste from three Utilities.
Hydro-Guard® Improves Water Quality And Saves Man-Hours For Central Texas Vacation Community
The user population of the Horseshoe Bay Water Distribution System does not reach its peak until summer and the resultant levels of peak and low usage vary widely.
FGD Purge Treatment In Coal-Fired Power Generation
Stricter environmental policies and regulations worldwide are changing how industry approaches all aspects of business. Likewise, EU (European Union) environmental policies governing air, soil, and water quality have become progressively stringent.
These policy changes affect the power industry’s balance of meeting growing European energy demands with compliance to environmental standards. In order to conform with EU standards specific for flue gas, a coalfired generation plant (at the time owned by Endesa, Italia, S.p.A.) in Monfalcone, Italy, undertook the measure of installing a state-of-the-art FGD (flue gas desulfurization) system at their facility. This system would remove SO2 (sulfur dioxide) from the emissions for the 336 MW coal-fired power station.
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.

ABOUT WASTEWATER DISINFECTION
Wastewater disinfection takes place after primary, secondary and sometimes tertiary wastewater treatment. It is typically a final step to remove organisms from the treated water before the effluent is released back into the water system. Disinfection prevents the spread of waterborne diseases by reducing microbes and bacterial numbers to a regulated level.
A variety of physical and chemical methods are used to disinfect wastewater prior to it being released into natural waterways. Historically, the chemical agent of choice for municipal wastewater treatment has been chlorine, due to its disinfecting properties and low cost. However, the rising cost of chlorine and concerns that low chlorine concentrations can still be toxic to fish and other wildlife, has given rise to more physical methods of wastewater disinfection being adopted such as ozonation or ultraviolet (UV) light.
The use of ozone as a disinfection agent has the added benefit of increasing the dissolved oxygen content of the treated wastewater. However, because the ozone has to be generated, ozonation can require prohibitive up-front capital expenditure compared to traditional chlorination. UV disinfection has been growing in popularity as a wastewater disinfection method, in large part because of the life-cycle economics of the equipment and the fact that, like ozone, there is no toxic residual.
