The Meadowbrook Dairy in El Mirage, California is part of a growing alternative energy initiative -the production of energy from renewable sources. In this example, the renewable source is manure provided by the dairy’s 2000 cows. Each day, 20,000 gallons of manure are collected, deposited and processed in an anaerobic digester. Methane is released which fuels a turbine that generates electricity. Enough power is generated to meet most of the daily needs of the 159 acre dairy.

The new machines will allow larger municipal wastewater plants to use air foil bearing blower technology despite the size limitations on single units.

Discover how the SL-Rat program realized over $51,000 in crew labor and financial savings, while reducing the risk of sanitary sewer maintenance issues, for the town of Oakland, Maine.

When it comes to digital transformation via ‘smart city’ technologies for leak detection or sewer overflow prevention, utility needs inevitably overlap with the economic and infrastructure interests of other city operations. Evaluating operating efficiencies in the context of three-dimensional (3D) ROI can uncover practical ways to drive greater dividends for all concerned — utilities, society, and the environment around them.

Here are some links and guidelines designed to help utilities change their perspective on water as a low-cost resource of virtually unlimited supply. 

For almost 50 years, CPS Energy of San Antonio has drawn water from the San Antonio River to recharge two man-made lakes that provide cooling water for their power plants.

The West African City of Abidjan in Côte d’Ivoire has historically provided drinking water to its five million residents from water treatment plants that use hydrated lime systems. But because of the high content of carbon dioxide in the local groundwater, up to 160 ppm, setting the water to calcium carbonate equilibrium using hydrated lime was economically, operationally and environmentally challenging for the city of Abidjan.

The Littleton / Englewood Wastewater Treatment Plant, just south of Denver, is the third largest publicly owned treatment works in the state of Colorado. It receives sewage from the cities of Littleton and Englewood, as well as 21 connector districts in a 75-square-mile service area. Farmer’s staff chose to implement an upgraded grit removal system supplied by Hydro International. Two complete HeadCell® systems were implemented – each consisting of one HeadCell® grit separation unit, one SlurryCup™ grit washing unit, and one Grit Snail® grit dewatering escalator.

Discover the solution that has helped a global miner experience improved reliability and reduced spending on spare parts and maintenance.

There is a common misconception about tube settlers that thicker material, whether it’s thermoformed or extruded, yields a stronger, more structurally capable module. On the surface, this seems like a reasonable assumption. However, when we look at the details of module design and construction, we see that this is not always true.

Any process plant constantly generates a high volume of status data. Today, this data can be extracted from the plant, stored, analyzed, and prepared to meet operator needs and lower marginal costs.

We arm municipalities with actionable data necessary to make informed decisions about water quality in their communities

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

In recent years, various perflorinated chemicals (PFCs) have come under increasing scrutiny due to their presence in the environment, in animals, and in human blood samples. There are two major classes of PFCs: perfluoroalkyl sulfonates such as perfluorooctanesulfonic acid (PFOS) and long chain perfluoroalkyl carboxylates such as perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA).

There are several basic methods for reducing harmonic voltage and current distortion from nonlinear distribution loads such as adjustable frequency drives (AFDs). Following is a description of each method, along with each method’s advantages and disadvantages.

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

A water management company in Serbia used Panametrics' ultrasonic flow meter technology for stormwater management, ensuring reliable measurement and accuracy in challenging conditions. The technology allowed for live monitoring of water transfer and reduced the risk of flooding.

In wastewater treatment, aerobic digestion enables plants to increase their capacity by injecting oxygen into the wastewater head space.

Homes, industry, schools, and businesses all generate sanitary waste, or sewage. Sewage treatment is a multistage process that cleans up wastewater before discharge or reuse. In the final step of the treatment, disinfectants are added to kill disease-causing organisms. Common disinfectants are chlorine gas and sodium hypochlorite. Chlorine dosage levels are designed to leave almost no residual in the wastewater after treatment

Despite their importance in modern wastewater applications, not all DAFs are created equal. Factors, such as the components that make up these systems, will influence how well they work and how long they last.
