Phosphorus removal during wastewater treatment is vital to ensuring public safety and protecting the environment. Removal of this nutrient from waste streams is key to preventing eutrophication – a natural process inciting algae blooms. Algae blooms can suffocate ecosystems, creating dead zones in which animal life can not survive. Moreover, this causes other water quality issues […]
Biogas conditioning is a critical process for biogas management. Biogas primarily consists of methane and carbon dioxide, but may contain constituents of sulfur species, silicon species, and moisture. Some of these elements can damage end use equipment, be dangerous to human health, and pollute the environment at high concentrations. Since biogas production is dependent on […]
While many of us savor the sounds, smells, and extended daylight of summer, wastewater treatment plant operators often dread it. The heat of summer requires constant attention to avoid plant upsets. Like it or not, summer is just around the corner, so now is the time to assess the health and history of your plant […]
Physicians use annual examinations to maintain the health of their patients and detect symptoms before they turn into something worse. Similarly, microbiological evaluations analyze the health of your wastewater treatment system to avoid potential issues and dreaded shutdowns. The microbes that drive your aerobic wastewater treatment system are only as effective as their environment allows […]
As part of its mission to produce naturally grown turkeys and turkey products in a responsible manner, a northeastern farm worked with the state’s energy department to develop a plan to maximize the beneficial handling of organic wastes in an environmentally acceptable manner. As you would imagine, the raising and processing of turkeys generates a […]
With the price of natural gas and other hydrocarbon fuels on the rise, it is becoming increasingly important for industry to search for methods to reduce fuel requirements (energy conservation, process optimization, waste minimization, etc.) and identify ways to recover energy for beneficial reuse. One area that should be thoroughly investigated is the potential to […]
Being one of the most well-known producers of customer-labeled ice cream and novelty products in the United States may sound great, but along with this prestigious distinction comes the challenges related to running numerous production lines with multiple product changeovers driven by seasonal variations in demand. As you can guess, waste minimization and wastewater treatment […]
A Midwestern sugar beet processor was struggling to handle the high-strength waste that was produced as the company processed sugar beets into refined granulated sugar. Before retaining ATI’s services to design the expansion of its wastewater treatment plant (WWTP), the company’s system consisted of two flume water clarifiers, several wastewater holding lagoons, an anaerobic contact […]
A leading producer of premium natural, organic beverages located California was struggling with a not-so-tasty byproduct of beverage production: the generation of high-strength process wastewater. In early 2003, the City’s POTW expressed its concern over the processor’s relatively high organic wasteloads. The company investigated a number of wastewater pretreatment options, finally selecting anaerobic technology as […]
Given the current economic situation, public and private organizations are quickly realizing the many advantages offered through partnerships on anaerobic digestion (AD) and combined heat and power (CHP) projects. In addition to financial benefits, partnerships can also offer a positive public image, green credits, additional power sources, solutions for waste reduction, and a way to […]
