Recently, Ohio Governor John Kasich issued an executive order allowing the Ohio Department of Agriculture to set requirements for storing, handling and applying manure as well as nutrient management plans in an effort to reduce nutrient pollution and algal bloom growth in Lake Erie. The order is set to affect 7,000 farms across 2 million acres.

Until 2012, the Kaufman, TX, Wastewater Treatment Plant (WWTP) operated two separate aeration basins with mechanical surface aerators. As the plant’s equipment aged and required more frequent and expensive repairs and maintenance, the City of Kaufman followed its engineering firm’s recommendation to install a new, more efficient, fine bubble-diffused air system rather than simply replacing its old mixers with in-kind equipment.

If you’re in the business of managing a water system — whether drinking water, wastewater or water used for industrial purposes — a luminometer can make your job easier.

A gourmet cheese, whey protein, and lactose production facility located in the Midwest had been utilizing a land application system for effluent discharge for over 40 years. Using a combination of ridge and furrow and spray irrigation, the plant had many years of success applying their wastewater to the land.

Innovation is vital in the water industry and continually moving ahead is a must — even if the company you're trying to surpass is your own. By listening to a wide range of customers and distribution chain partners, Mazzei Injector Company upgraded its revolutionary Pipeline Flash Reactor (PFR) and introduced it to the marketplace with great impact.

A community wastewater system can provide valuable information about public health conditions in an anonymous and rapidly accessible manner. One area where this is especially powerful is infectious diseases, which are shed into wastewater systems. In response to the global COVID-19 pandemic, the scientific community has rapidly mobilized to determine if wastewater monitoring for SARS-CoV-2, the virus that causes COVID-19, could be detected and quantified in wastewater streams and sludge.

How do I remove screenings from my sludge? Even when screens are installed at the head of a treatment facility, debris always ends up in the sludge. Plastic parts and fibrous materials can cripple operation of important downstream technologies.

In communities across the United States, wastewater treatment plants are consuming vast amounts of energy to remove and dispose of energy rich organics. As any government comptroller can attest, the cost of the energy required to run a conventional activated-sludge treatment plant takes up a large portion – up to 40% – of a municipality’s budget.  Ironically, the very substance being treated could produce more than enough energy to run the treatment plant itself.

Landlocked, shallow bodies of water such as recreational ponds, irrigation, drinking water and animal waste lagoons have a major problem with flow. The only natural methods of movement in these bodies of water are the slight Coriolis Effect of the earth and wind.

Among the pump stations managed by Branford, CT, is a long-term problematic station located at Burban Street. There were two primary problems at this station: 1) clogging from modern day trash and raggy, stringy materials, and 2) fats, oils, and grease (FOG) from a nearby nursing home and restaurants, which accumulate and float on the water surface, resulting in a horrendous mess.

This application note from Aqua-Aerobic Systems highlights the effectiveness of the AquaStorm® Cloth Media Filter as a flexible, compact, and highly efficient solution for Combined Sewer Overflow (CSO) and Sanitary Sewer Overflow (SSO) events.

Limits of Detection and Quantitation are key to understanding analytical instrumentation capabilities, especially when non-optimal process control can lead to damage of sensitive equipment due to insufficiently accurate readings.

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.

As old gas & oil fields play out, newer methods must be used to extract resources from areas where they are locked in layers of shale. One current technique is known as “fraccing,” in which high pressure water is pumped into the well shaft to “fracture” the rock layers, allowing more natural gas to escape and be collected. However, this technique poses a number of environmental problems, including contamination of water with hydrocarbons, solid particulates, and scale producing ions — making it unsuitable for reuse.

SensyMaster helps to improve the operating costs of the most cost intensive process in sewage plants: Aeration. High-measuring performance and state of the art technology helps customers increase plant efficiency.

This application note explores how Greenline pumps enhance odor control systems by delivering precise chemical dosing for odor mitigation and pH control, ensuring cleaner air and improved quality of life.  

A municipal wastewater plant in North America sought a reliable flow measurement for one of their key wastewater lines. The existing dual-channel ultrasonic flowmeter from a competitor had consistently failed to provide accurate readings.

A municipal association needed to understand if wastewater was being equally distributed across two cast iron pipes within its wastewater treatment plant. Learn how clamp-on ultrasonic measurement helped successfully measure the flow.  

Power plants and refineries around the world must manage and treat complex effluent waste streams from the Flue Gas Desulfurization (FGD) process. Flue gas is generated by the combustion process of fossil and fossil-derived fuels, such as coal, oils, and natural gas in power plants. Petrochemical refineries may generate flue gas from a number of different processes, including Catalytic Cracking, Steam Methane Reforming, and Heaters or Furnaces.
