WASTEWATER DISINFECTION WHITE PAPERS & CASE STUDIES
Biological Nutrient Removal (BNR) is allowing many wastewater treatment plants to achieve extremely high effluent quality. Still, for some applications even the most advanced BNR processes can’t address concerns with trace organics, pharmaceuticals, and other endocrine disrupting compounds (EDCs).
Ozone For Industrial Cooling Water Treatment
Infraserv Hoechst is a leading company for operating large-scale industrial and chemical production complexes. It is a complete service provider offering services such as purchasing, engineering, and facility management, and it has a full supply of products such as compressed air, steam, cooling water, purified water, technical gases, and energy.
Ozone Plays Critical Disinfection Role At Water Reclamation Plant
The Rio Grande River and the two major aquifers in the El Paso, TX, area had been dried up for decades when El Paso Water Utilities (EPWU) developed the Fred Hervey Water Reclamation Plant, the nation’s first full-scale wastewater reclamation plant to use tertiary treatment to restore wastewater to national and state potable water standards.
Turbidity And T&O Issues Eliminated With Environmentally Friendly Treatment Technologies
The Metropolitan Water District of Salt Lake & Sandy (District) in Draper, UT, integrated a mix of complementary treatment barriers to address specific disinfection, turbidity, and taste and odor (T&O) issues shared by many surface water treatment facilities while also instilling the needed capabilities to adapt to changing regulatory requirements.
Systems Work In Series To Increase Filter Run Times, Reduce Water Use, And Improve Finished Water Quality
The city of Florence, Colorado Water Treatment Plant (WTP), located 75 miles south of Denver, uses blended surface water taken from the city’s southernmost water reservoir.
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.
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.

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.
