At a water treatment plant that provides drinking water for distribution to a large area of customers, a contractor decided to switch to SITRANS FM MAG 5100W flowmeters. A local representative saved a the contractor time and money by recognizing the need for the magmeter to be isolated from the piping protection before startup, which also saved the customer from added downtime.
Wastewater can be both corrosive and abrasive. To ensure reliable and cost-effective pump operation, it is important to select a wastewater pump made from the most suitable material for your wastewater.
The objective of this white paper is the prediction of the wastewater treatment plant (WWTP) sludge production and subsequent power savings realized from operating the aerobic digesters via facultative digestion using technology from ENNIX(6) INC. Development of the predictive spreadsheet permits one to demonstrate the power savings to potential users of the facultative digestion(6) technology.
A natural, environmentally safe and cost-efficient way to ensure that your pond maintains a healthy, aerobic state is through the use of aeration systems. By Robin Bio, Marketing Coordinator
The newly patented Dif-jet™ Floating Aeration System aerates water above the surface and pumps the aerated water under pressure back into the pond through unique discharge configurations to produce large areas and variable depths of aerated water.
SNIACE S.A. is a pulp mill located in Spain with an annual production capacity of 66,000 tons of dissolving pulp from Eucalyptus. Forty percent of the pulp is used in their own viscose plant, and the remaining 60 percent is sold to the market.
The sewer utility for the City of Andalusia, AL, was in line to receive stimulus funds for energy-related conservation projects, but the proposed use for replacing aging pumps at two lift stations along the municipal sewage collection system had to be fully demonstrated to be eligible. The prerequisite for eligibility required at least 30 days of documented monitoring to substantiate a guaranteed 25% reduction in electrical consumption.
The town of Wilson, Wyoming - nestled along serene Fish Creek, is home of the famous Teton Pass. In the winter, Teton Pass is used by thousands of visitors as a backcountry skiing and snowboarding playground, with acres of snow-covered terrain. In the summer, Teton Pass offers everything from downhill mountain biking to casual day hikes surrounded by an abundance of colorful wildflowers. Each year, the area grows in popularity, bringing new tourism and population growth alike. By The Gorman-Rupp Company
The Picnic Point Wastewater Treatment Facility was faced with reaching their plant processing capacity. The plant was sending its biosolids to be incinerated and part of this challenge was to find a way to manage the biosolids produced by this facility. Hauling and disposing of this sludge was difficult and becoming expensive. It was desirable to have a Class A biosolid to alleviate this concern and be more environmentally conscious.
Ashley Valley Water & Sewer Improvement District (AVWSID) serves rural county residents who live outside the city of Vernal, Utah.
When the Sanitation Districts of Los Angeles County (LACSD) were formed in the 1920s, the agency embarked on its first major project -- the construction of the backbone trunk sewer of the Joint Outfall System (JOS). Since then, the Sanitation Districts have completed many challenging projects, providing environmentally sound, cost-effective wastewater and solid waste management services to over five million people in Los Angeles County.
Rising energy prices have made accurate energy measurement a hot topic in recent decades. The need for accurate measurement technologies extends to many different application areas, including heating and cooling; compressed air; steam production and distribution; heavy fuel oil consumption; energy monitoring; and custody transfer. In response, new technology is being developed that integrates tasks previously requiring several measurement devices.
Chlorine has long been used as a primary disinfection method for many water and wastewater treatment applications. However, there is growing concern about the harmful DBP’s produced by the use of chlorine.
A new pipe-repair solution promises to save time and money, while also being sustainable, long-lasting, fully scalable, and safe for workers.
The Minnesota River Valley Public Utilities Commission (MRVPUC) provides wastewater treatment for the City of Le Sueur and the City of Henderson in south-central Minnesota. A significant factor facing the utility is the highly varying phosphorus load that challenges operators to meet the utility’s annual average discharge limit of 1.0 mg/L total phosphorus.
Excess ammonia in receiving waters causes algal blooms that decrease oxygen levels. For this reason, many wastewater treatment plants (WWTPs) must limit ammonia in discharge. Mike Rousey, Hach Company
This application note presents comparative data obtained on influent and effluent wastewater samples using laboratory and on-line TOC analyzers employing the heated sodium persulfate oxidation technique in USEPA-approved methods 415.3 and SM 5310C.
The Lancaster Area Sewer Authority’s (LASA) recent $26.8 million upgrade to its lone wastewater treatment facility promises to reduce the plant’s environmental footprint and save costs by emphasizing energy efficiency and allowing for biosolids reuse.
Three key events from 2015 could reshape the water/wastewater industry in 2016 and for years to come.
Thermal hydrolysis is an innovative wastewater solids conditioning process that boasts many advantages — financial, environmental, and otherwise. Is your plant a good candidate?
While chlorination has long dominated water disinfection, new approaches and technologies have emerged in the wake of disinfection byproduct (DBP) regulations. Could peracetic acid (PAA) be the option that dethrones the king?
The “flushables” scourge has cost utilities all over the world millions of dollars and countless hours of maintenance. Some groups are attacking the problem at its source.
We are programmed to believe that the word “fouled” is inherently bad, identifying something that is dirty, unclean, or contaminated. But for those of us in the membrane industry, the physical presence of “foulants” simply confirms that our treatment was necessary and that our process is successfully producing a more pristine effluent.
