As some of you may have heard, LuminUltra has partnered with Microbe Detectives to offer DNA testing services to the drinking water and wastewater industries. So “Who’s on First?” (pun intended); simply put, the partnership’s combined technologies tell you who is in a given water or wastewater sample, and how much is in that sample.
Packaged Wastewater Treatment Plants offer many advantages, flexibility notwithstanding. One plant in particular, located in Georgia, needed to be upgraded to handle the increased flows from a growing city and to address new effluent discharge regulations. The tight plant site offered minimal opportunity for routine expansion of the packaged wastewater plant volumes, hence special designs were needed. Learn how this 200,000 GPD system is thriving.
Aeration Industries International, Inc. is playing a key role in cleaning up water worldwide to help preserve the earth’s most precious resource, water. When the Chinese city of Lin An planned an expansion to their oxidation oval system, officials were looking for a new type of aeration system that would offer process performance and trouble free operation. The company's AIRE-O2 TRITON process aerator/mixers were the ideal solution for the Lin An wastewater treatment facility.
When the Jacksonville, Florida Naval Air Station needed to increase oxygen in their aeration basins, they turned to RWL Water. Five submersible HURRICANE aerators provide bottom-up mixing, drawing surface air and dispersing it in a 360-degree pattern near the basin floor. Long bubble hang time results in excellent oxygen transfer, and ensures excellent BOD and ammonia removal, treating flows up to 3 MGD.
Disposable, throw-away products are making raw sewage pumping tougher than ever. The Jefferson Street Pump Station at the City of Centralia, WA had a problem demanding a cost-effective solution. By Glenn Dorsch, P.E, VP/Chief Engineer, Vaughan Co. Inc.
In late 2013, Headworks Bio Inc. was awarded a contract with General Contractor Soluciones Tecnicas Ambientales, S.A. (SOLAMSA) to supply an IFAS system to upgrade the existing Ptar El Roble conventional activated sludge (CAS) treatment facility in Puntarenas, Costa Rica — the first IFAS installation in the country.
The successful addition of new restaurants and clubs at a resort and casino in Upstate NY brought with them a flow of fats, oil and grease (FOG), which gelled into a floating blanket atop the main station’s wet well, where the sewage flows converge from the network of smaller stations throughout the property boundaries.
The Littleton/Englewood wastewater treatment plant, Colorado, put in place processes to effectively monitor the levels of ammonia in their wastewater treatment.
Hypochlorite has some significant environmental concerns associated with DBPs and residual toxicity.
Nitrate is present in high levels in wastewater due in part to the high nitrates present in human sewage but also from some types of industrial effluent entering the municipal sewer system.
The clarity of water in a stream, river or ocean is a key determinant in fostering a healthy and balanced aquatic ecosystem. The clearer the water, the greater the ability of light to penetrate to aquatic plants which generate the oxygen needed for aquatic life.
UV disinfection systems disinfect water using UV light at the 254 nm wavelength. UV light at this wavelength actually destroys the DNA of microbiological material in the water which prevents dangerous viruses such as cryptosporidium and e-coli from reproducing and causing harm.
Radar technology is often viewed as the “best” method of level measurement, but this isn’t necessarily true in the water industry.
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
Water quality laboratories across the nation are faced with both a rising level of water quality awareness amongst the general public, as well as rising costs in water quality monitoring. As a result, laboratories are looking for more efficient ways to provide higher quality monitoring.
Clarifiers are an important component of the wastewater treatment process. However, between corrosion, maintenance, and changes in flow, it can be difficult to keep a clarifier operating at peak performance. In addition, changes in effluent regulations may require upgrades to meet new, more stringent requirements.
This article is the seventh in a series on industrial water treatment focusing on inorganic contaminants; this one will discuss capital, operating, and lifecycle costs.
Traditionally, cities have relied on gray stormwater infrastructure — conventional piped drainage systems — to move urban stormwater away from the built environment. However, stormwater runoff is a major cause of water pollution in urban areas with runoff containing heavy metals, trash, bacteria, and other pollutants from the urban landscape. High flows can also cause erosion and flooding in urban waterways, damaging habitats, property, and infrastructure.
A group of people are wading slowly through high grass under a hot summer sun as they begin a guided walking tour of the Walton Floodplain in Delaware County, New York.
A new generation of electrocoagulation-based water treatment has successfully treated wastewater and effluent from a remote onshore natural gas exploration and production project with over three years of continuous operation. To compound the challenges of treating this wastewater and effluent, the unit was required to operate in an extremely environmentally sensitive environment — a pristine tropical rainforest.
Wastewater consultant and trainer Dan Theobald (“Wastewater Dan”) dives deeper into the activated sludge process with calculations focused on MLVSS.
