The Metropolitan Water Reclamation District of Greater Chicago (MWRD) — of which the Terrence J. O’Brien Water Reclamation Plant (WRP) is part of — has made a number of upgrades to its treatment process in recent years.
pH measurement plays an important role in virtually every industrial process and an equally essential part in environmental regulatory compliance. Many of the below questions pop up every day whether in chemical processing plants, power plants, water and wastewater plants or biopharmaceutical processing.
While most of the country was seeing red, white, and blue this past Fourth of July, many Florida residents were seeing green.
Sherbourne Common is an innovative waterfront park that provides the public with green recreational space along Lake Ontario in a former industrial area.
The Independence Hill Conservancy District's Taney Lift Station was having continuous problems with wipes, swiffers, and plastics deposited in the incoming lines, which then broke loose in storms and overwhelmed the old non-clog pumps.
A major power plant in Thailand is using 3M™ Liqui-Cel™ Membrane Contactors to remove carbon dioxide from a DI water system. The system is an expansion project and will be used to feed a high pressure boiler. Liqui-Cel membrane contactors are being used to lower the CO₂ inlet into an Ionpure Electrodeionization (EDI) system. Carbon dioxide adds an ionic load to the EDI system, which can reduce the performance of the system. Manufactures of the EDI equipment suggest lowering the inlet CO₂ to reduce the load on the equipment and improve the water quality.
This is the first of a three-part series examining wipes in the waste stream. This first installment looks specifically at the growth of disposable wipes usage within the last decade.
The Smurfit-Stone Hopewell mill needed to replace the existing three evaporator trains that were currently in place at this facility with one very highly integrated system.
By incorporating Membrana UF and Gas Transfer Membrane (GTM) a resort customer was able to reduce the risk of contaminating its cooling water and protect other system components from corrosion. The compact systems exceeded performance expectations and reduced maintenance and operating costs while maximizing the available space.
The use of Vaughan's self-priming chopper pump and nozzles upstream of the influent screens is increasing the amount of fecal matter passing through the influent screens, which in turn improves plant efficiency and greatly increases the amount of cogenerated electricity from digester gas.
