U.S. Steel Chooses Data Delivery Services for Water Discharge Waste Flow Monitoring

When a requirement for three flowmeters for Great Lake’s discharge water in the "hot roll" process were required Hach’s Data Delivery Services was selected.

Cleveland Metroparks Zoo Upgrades Flowmeter

Home to more than 3,000 animals representing 600 species, the Cleveland Metroparks Zoo is a popular attraction enjoyed by people of all ages. The Facilities Operations Department’s tasks, many of which are performed behind the scenes, ensure that all of their visitors have a safe and enjoyable visit by keeping everything running smoothly. The monitoring of wastewater flow is one of the “out of sight, out of mind” operations that visitors never have to think about. However, it’s definitely on the minds of those working in the Facilities Operations Department.

Three Decades Strong

For nearly two decades, Elco Corporation has chosen innovative Marsh-McBirney open channel flow monitoring products to provide accurate flow data for its billing application. Today, it continues that tradition for another decade.

Flow Service on the Cutting Edge

The prioritization of municipal sewer system rehabilitation work to reduce inflow and infiltration (I&I) is based largely on the selection of projects that will most quickly provide the largest return on investment. Strategies to determine this vary from municipality to municipality; however, performing service lateral rehabilitation work first is critical to the success of any comprehensive municipal rehabilitation program.

Data Centered

Large Colorado WWTP reduces operating costs with automated data control systemThe Littleton/Englewood Wastewater Treatment Plant (LEWWTP) is the third-largest publicly owned treatment works (POTW) in the state of Colorado. LEWWTP is rated at nearly 50 million gal per day (mgd) and currently runs at about 22 mgd. The large plant, positioned along the South Platte River near Denver, is required to exceed secondary treatment requirements by removing ammonia and nitrate from wastewater.

Is Your Plant Secure?

An update for plants and utilities; new information about cyber securityIn September 2007, an experiment called “Aurora” was made public. The project involved a Department of Energy laboratory in Idaho Falls, Idaho—with permission and funding from the Department of Homeland Security (DHS)—hacking into a power plant’s control station via computers and digital devices. By doing this, the lab was able to change the operating cycle of a generator, thus severely damaging it and sending it out of control.

DDS Proves to be Simple & Reliable

A new approach to flow monitoring in Carmel, Ind.When simplicity and reliability were required for a flow-monitoring project in Carmel, Ind., the solution was Marsh-McBirney’s data delivery services (DDS) program. This article describes how the program eliminated day-to-day flow monitoring and provided city personnel accurate flow data directly to their desktops.

Fine-Tuning the Treatment Process

Pinpointing DO concentration optimizes aerobic digestion for Illinois WWTPReplacing high-maintenance membrane probes with accurate luminescent technology for online measurement of dissolved oxygen has helped bring greater efficiency to the aerobic digestion process at the Paris, Ill. Wastewater Treatment Plant (WWTP).
Maintaining optimal dissolved oxygen (DO) concentrations in its twin aerobic digesters has long been a key objective at the 1.4-mgd plant in east-central Illinois.

Experience

Jim Darby, a senior staff engineer and product manager for Marsh-McBirney, a Hach Co. brand, has seen it all in his 30+ years in the water and wastewater flow industry.

From experiences involving flow meters on nuclear submarines to municipal applications in the Boston area, Darby has a vast array of flow meter-related knowledge to draw upon.

Drive-Through Metering

Flowmeters help Allen County, Ohio, solve I&I problem
A long-range inflow and infiltration (I&I) plan is currently underway in Allen County, Ohio. The Wastewater Treatment Division operates three major treatment plants located in Bath, Shawnee and American Townships and three smaller package treatment plants located in Bath and Richland Townships. The Wastewater Collection Maintenance Division is responsible for the maintenance and operation of approximately 170 miles of sewer lines and 46 sewage lift stations located within American, Bath and Shawnee Townships.

Bacterial Control with Ozone

In the April 2001 issue of Water Quality Products,associates of TCET presented a new method using ozone to treat cooling tower water. Cooling Treatment Systems, Inc. (CTS) of Englewood, Colo., has adapted this method to produce a water treatment system it now is marketing for cooling towers. CTS submitted this new technology to TCET for testing. The results of these tests are presented here.The Center for Environmental Technology (TCET) at Pierce
College, Woodland Hills, Calif., is engaged in the development and testing of

Flow Monitoring Springboards City to System-wide Sewer Management Solution

The forward-looking Metropolitan Sewer District of Greater Cincinnati (MSDGC) saw a dynamic model of most of Cincinnati's collection system as the tool that would support improved sewer system management, including sanitary sewer overflow (SSO) and combined sewer overflow (CSO) control, planning, and operations. Establishing a dynamic model of most of Cincinnati's
collection system was an ambitious project.

Chlorine Residual Boosting in Distribution Water

When it comes to the methods to increase, or boost, the low level of disinfectant in distribution water, information is scarceThere is no shortage to the available information in regard to disinfection methods from principle to application. Two common disinfection methods are to apply chlorine gas to the plant water, or to make the chloramine from ammonia and chlorine in the plant.
