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 […]

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 […]

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 […]

Rice Lake Utilities owns and operates a 2.2 mgd wastewater treatment facility (WWTF) that treats wastewater generated within its service area in the City of Rice Lake and discharges to the Red Cedar River. The original plant on the site was built in 1951. The liquid treatment facilities consisted of primary clarification and a high […]

Early detection of a potential upset in an anaerobic digester can prevent weeks or even months of frustration and recovery headaches. One of the best and earliest indicators of a healthy or unhealthy digester is methane production. A drop in the percentage of methane in digester gas is one of the first signs that your […]

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 […]

Whether or not you have ever heard of a siloxane, there is no doubt that you have encountered many. They play an important behind-the-scenes role in our daily lives; they have washed our hands, brushed our teeth, cleaned our clothes, driven us to work, helped us lose weight, and even print our newspapers. Siloxanes are […]

Biogas, a renewable energy source, is one of several benefits associated with anaerobic wastewater treatment. With rising fuel costs, options exist even if a low volume of biogas is being generated. However, the abundance of biogas utilization alternatives can often make the question of what do with your gas difficult to answer. If a system […]

How much gas can you produce? No, not personally. We’re talking about the potential to produce biogas, a valuable energy source, from a waste or substrate. This determination can be made using a simple and inexpensive procedure to check relative anaerobic activity and biodegradability: the Biochemical Methane Potential (BMP) test. A laboratory evaluation can provide […]
