Abrasion- And Corrosion-Resistant Metal Cutters For Harsh Sewage Grinder Environments

Wastewater is tough on grinder cutters. Damaging abrasion wear and metal corrosion are caused by daily gritty material and acidic conditions in sewage. The combination of an abrasive and corrosive environment accelerates the loss of cutter material, resulting in the loss of cutter thickness and tooth edges.

Constructing A Winding Box Culvert Channel In A Steep, Rocky Canyon

Special precast box culverts were used for one of the most significant segments of the $25.8 million emergency water restoration project, designated by the NRCS, known as the Cache Water Restoration Project (CWRP). The CWRP project involved the reconstruction and improvement of approximately six miles of mostly open, unlined channels that make up the Logan and Northern, as well as the Hyde Park and Smithfield canals. The project incorporated new precast pipeline, box culverts, a section of pressurized pipe, metering systems, turn-outs, head gates, and improved maintenance access.

No More Odors Here In Bakersfield California: Replacing Calcium Nitrate With SulFeLox®

Faced with increasing costs for controlling hydrogen sulfide in its wastewater collection system, the City of Bakersfield, California commissioned an evaluation of its program in 2019.

Are Bypasses Needed With Today's Waterworks Gate Valves? New Information Says They're Not.

Up until recently, there was no empirical data to support the position that bypasses, for the routine operation of resilient wedge gate valves, are not needed. 

Using Supersaturated Dissolved Oxygen To Reduce Costs And Increase Treatment Capacity

Supersaturated dissolved oxygen (SDOX®) can cut aeration-related energy costs in half for a range of applications, including activated sludge systems, oxidation ditches, odor control in collection systems, and more.

Squeezing Every Last Dollar From Biogas

A growing number of wastewater treatment plants are banking on biogas from their sludge as a supplemental power source. Unfortunately, biogas is notoriously difficult to quantify. Ultrasonic flow meters specifically designed for biogas applications can provide a solution that addresses many of the issues created by traditional technology.

Onsite Wastewater Treatment Technologies To Be Considered For Large And Small Projects

There is a greater need to raise awareness for better sanitation, water reuse, and storm water solutions with better simple, low-cost, robust technology.

Stormwater Tanks

Discover how stormwater detention tanks can aid in stormwater management, which involves reducing runoff into surrounding areas and improving water quality. 

FlexRake Bar Screens At 24+ Sites Around Houston Were Unaffected By Hurricane Harvey

Despite the destruction of Hurricane Harvey in August 2017, Duperon wastewater screening systems in the cities of Cuero and Refugio, Texas – approximately 150 miles southwest of Houston – were virtually unaffected by the storm. Duperon’s FlexRake bar screens, installed at both locations as well as dozens of other sites in and around Houston, remove objects like rags, paper, plastics, and metals to prevent damage and clogging of downstream treatment equipment. Both communities found essentially no damage to their wastewater screening equipment.

What Private Utilities Need to Know About Nutrient Loading and Eutrophication

For private utilities, discharging wastewater isn’t a one-size-fits-all process. If your facility serves a resort, a golf course, a residential community, or a mixed-use development, you’re likely discharging into smaller, localized water bodies (creeks, ponds, wetlands), not large rivers or oceans. And while these ecosystems are beautiful they’re also incredibly vulnerable to nutrient loading and eutrophication.

Dissolved Oxygen Measurement

One of the most important measurements in the determination of the health of a body of water is its dissolved oxygen content. The quantity of dissolved oxygen in water is normally expressed in parts per million (ppm) by weight and is due to the solubility of oxygen from the atmosphere around us.

Scrubber Application

This customer supplies district heating and electricity for the region of Sønderborg. For one of their waste applications a MAG meter failed within 6 months, and was successfully replaced with a Panametrics Aquatrans AT600.

Pile Cloth Media Filtration For Clean Utilities

Cooling towers and boilers consume the most fresh water in the industry, with industrial process waters carrying the balance. Power plants and refineries use more water volume for the cooling process than any other area of the facility. Mining and food and beverage industries consume higher volumes for their processes. Clean water may come from a range of sources, including clarified surface waters, groundwater or properly treated wastewater (reuse) sources.

Why Measuring Hydrogen Sulfide In Wastewater Matters

Hydrogen sulfide (H₂S) gas in wastewater environments is a familiar concern. But waiting until its odor is detected can be too late to exert as much control over it as desired. Fortunately, a new ability to monitor H₂S concentrations — in the liquid wastewater stream, in real time — is advantageous for wastewater professionals in terms of safety, cost, and consumer complaints. Here are four ways to capitalize on that capability.

Ultrasonic Level Measurement In Water And Wastewater Plants

Radar technology is often viewed as the “best” method of level measurement, but this isn’t necessarily true in the water industry.

Determination Of EN15662:2008 - Determination Of Pesticide Residue In Food Of Plant Origin, By An Automated QuEChERS Solution

Pesticide residue laboratories are required to undertake analyses of an ever increasing number of samples. The analyses typically involve use of multi-residue methods (both GC-MS and LC-MS) to test for over 500 pesticide residues.

Active Energy Control – Energy Reductions Of Up To 10% Above Standard Drives

Energy costs continue to increase. At the same time, there is increased pressure to reduce utility bills without sacrificing operations or comfort.

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.

Process Monitoring And Control For Increased Productivity And Efficiency

The Littleton/Englewood wastewater treatment plant, Colorado, put in place processes to effectively monitor the levels of ammonia in their wastewater treatment.
