WASTEWATER DISINFECTION WHITE PAPERS & CASE STUDIES
The communities serviced by the Rensselaer County Sewer District, collectively known as the Albany Pool, have combined sewer systems (CSS) that bring stormwater, sewage and industrial wastewater directly to the wastewater treatment facility. When a storm or snow melt results in exceeded capacity, local waterways become contaminated, resulting in a significant environmental challenge, especially in a community where recreational swimming, boating and fishing are popular in warmer months.
Activating The Sludge In Small Municipal Facultative Waste Lagoon Systems
Wastewater treatment lagoons were originally facultative in design — shallow, single and multi-cell lagoon systems that counted on wind, sunlight, anaerobic bacteria, and time for the digestion of the organic components of the wastewater.
BNR + MBR Equals Success At Water Reclamation Facility
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 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).
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.

High-Efficiency Water Treatment Using A Novel UV-Light System
Many harmful substances in waste water stubbornly resist being broken down by biological waste water treatment plants. Fraunhofer researchers have developed a photochemical reaction system in which water can be reliably treated at high flow rates by UV light without having to add chemical catalysts.
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.
