Rhode Island Wastewater Plants Key To Water Quality Reversal

Despite evidence that often points to the contrary, many bodies of water around the country stand as prime examples of how environmental quality can be improved with the proper will and effort.

$0 CAPEX Model Aids Innovation In Changing Water Environments

Managers of industrial, municipal, and agricultural water quality or water use monitoring can attest to the challenges of balancing depth of detail against the costs of achieving it. Now, an Infrastructure-as-a-Service (IaaS) business model is rewriting the economic impacts of those challenges by repackaging water monitoring capabilities to meet evolving needs more efficiently.

Vacuum Dosing Chemical Feeder For Chlorination And Dechlorination Helps Minimize O&M Costs For City Of Nashua, NH CSO Screening And Disinfection Facility

As part of its Long Term Control Plan to reduce combined sewer overflows (CSOs) to the Merrimack River, the City of Nashua, NH constructed a new Screening and Disinfection facility (SDF) to reduce untreated discharges of CSOs to the Merrimack River.

Mixing Comparison: Hydraulic Or Gas

Fairfield-Suisun Sewer District (FSSD) in California installed a Vaughan Rotamix hydraulic mixing system next to an identical anaerobic digester with a 7-year-old gas mixing system.

Vortex Wastewater Pumps Vortex pumps are primary sewerage pumps used to transport are sewerage through the wastewater treatment plant process. Because these pumps are required to handle the raw sewerage including grit and associated storm water runoff debris the abrasion rate is quite high. In this plant the pumps were lasting less than 1 year before severe abrasion caused reduction in tolerances leading to re-circulation. As the sewerage was no longer being efficiently transported to treatment the plants capacity was effectively reduced. Plant was considering replacement after 1 year a t a cost of $8,500.00.

Getting A Better Handle On Open Channel Flows

Flow meter choices are plentiful when it comes to full pipes, but the lack of options for open channels and partially filled pipes in wastewater and stormwater applications presents a special challenge for municipalities. In many of those cases, utility managers are contending with water contaminated with foam, oil, grease, or debris. The good news is that economical and reliable open channel flow meters are available to tackle those issues.

VTScada And OpWorks Provide Advanced Wastewater Reporting And Analysis

Prison Facility Eliminates Frequent Submersible Pump Clogs With Above-Grade Approach

When a correctional facility underwent a capacity expansion, changes to its problematic submersible sewage pumping station coincided, resulting in a new operator-safe approach to combatting the ills of prison sewage pump clogs.

Ultrasonic Sludge Disintegration: A 'Bubbly' Solution For Anaerobic Digestion Or BNR

‘Sonicating’ sludge proves to be a sound method for handling biosolids. By Bryen Woo, aerobic digestion product manager and James Goldhardt, anaerobic digestion group manager, Ovivo

Recording & Control: Online Data Recording And Control In Anaerobic Digestion Processes

Solids present in wastewater need to be safely and comprehensively treated and removed. This means not only removing toxic compounds, including both organic and inorganic materials such as heavy metals, but also eliminating any harmful bacteria present in the solids.

Analyzing Total Organic Carbon In Sea Water

The analysis of Total Organic Carbon (TOC) in seawater can be both challenging and expensive. The concentration of organic carbon in seawater is of considerable interest. The effect this matrix can have on TOC analyzers can lead to rapid consumable turnover, costly maintenance and repairs.

Optimizing Brine Flow In A Geothermal Power Plant

Different flow meter technologies were used in this geothermal power plant to monitor and measure brine. However, these traditional technologies failed. That’s where Panametrics PT900 Portable Ultrasonic Flowmeter was able to help.
