Wastewater Filtration Resources

41. Filter Installations Remove Solids From FGD Scrubber Effluent 4/9/2019

    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.

42. The Role Of IoT And Control Technologies In Water Filtration Systems 10/16/2018

    Filtration and separation technologies are the core of water treatment processes, and in many cases, they can be critical process bottlenecks. 

43. Dual Parallel Lateral Filter Underdrains Selected To Replace Underperforming Nozzle Design At Mexico's Largest Drinking Water Treatment Plant 10/3/2018

    Located about 78 miles (125 kilometers) west of Mexico City lies the municipality of Villa de Allende, home of Mexico’s largest potable water treatment plant. The Los Berros water treatment plant was constructed in 1980 by the National Water Commission (Conagua), an agency of the Mexican government that manages the nation’s drinking water and wastewater treatment. The plant provides 396.3 million gal/day (1.5 billion L/day) of water to the country’s capital city, equivalent to approximately 25 percent of the total water supply of the western hemisphere’s most populace metropolitan area.

44. World's Largest Denitrification Plant Helps Tampa Bay Reduce Nutrient Pollution 10/2/2018

    Nutrient pollution is getting worse in many estuaries throughout the United States, especially those on the heavily populated East Coast.

45. On-Site Sodium Hypochlorite Generation Replaces Hazardous Cyanide In Precious Metal Extraction 10/2/2018

    The Baia Mare Aurul gold mine in North Western Romania suffered a historic catastrophe in January 2000, when its dam burst, streaming out 100,000 cubic meters of waste water, largely contaminated with cyanide, commonly used in the process of mining gold, into tributaries of the Tisza River, a major waterway in Hungary.

46. Denitrification Filters Meet Strict, Varying Nitrogen Limits 10/1/2018

    The cities of Littleton and Englewood, CO, just south of Denver, share a wastewater plant — the Littleton/Englewood advanced wastewater treatment (AWT) plant located in Englewood. The 7886 m3/hr (50-mgd) Littleton/Englewood AWT plant serves more than 300,000 residents in the Denver metropolitan area. The facility also receives sewage from 21 districts within a 75 square mile service area. Plant effluent is discharged to the Denver metro area’s major watershed, the South Platte River.

47. Award-Winning Design Helps WWTP Protect Chesapeake Bay Watershed 9/26/2018

    Arlington County’s Water Pollution Control Plant (WPCP) in South Arlington, VA, is located on 35 acres of land squeezed into a commercial/residential neighborhood less than a mile west of Ronald Reagan Washington National Airport. The facility treats flows from nearly all of Arlington. In addition, nearly 20 percent of the plant’s flow comes from neighboring localities such as Alexandria, Fairfax County, and Falls Church. Effluent from the plant is discharged into Four Mile Run to the south, which feeds into the Potomac River and, ultimately, the Chesapeake Bay.

48. Methanol Dosing Technology Helps Denitrification System Pass Rigorous Performance Test 9/25/2018

    In 2007, Greenville, SC-based Western Carolina Regional Sewer Authority (WCRSA) conducted a rigorous performance test on a new tertiary treatment technology to assess its ability to effectively remove nitrate-nitrogen (NO3-N) without using excess amounts of methanol at its Lower Reedy Wastewater Treatment Plant (WWTP).

49. Denitrification Technology Helps Wastewater Treatment Plant Meet China's Stringent Class 1A Standards 9/25/2018

    China has implemented more stringent environmental standards in recent years. Local environmental protection departments now require urban wastewater treatment plants to apply strict enforcement measures to meet effluent discharge standards.

50. Improving The Quality Of Secondary Wastewater For Indirect Potable Reuse—From Pilot To Full Scale Plant 8/29/2018

    In spite of the recent abundance of water, many of California’s aquifers continue to balance on the edge of water scarcity. Decades of overpumping have reduced the amount of ground water available to supplement surface water resources diminished by drought. The Pure Water Monterey Ground Water Replenishment Project (Monterey Pure), addressed the need to replenish a local aquifer, by piloting Advanced Water Treatment (AWT) processes, to determine the best method to convert secondary wastewater into a pure water resource.
