Town operators were plagued by high level alarm call outs at two new sewage lift stations. Read how they used Greyline`s hybrid ultrasonic level controllers with dual sensor capability to put an end to level alarms.
An Ontario municipality deploys Portable flowmeters to solve flow rate discrepancies between sewage pump station effluent and lagoon influent flowmeters. Faced with suspension of construction permits due to flow rate uncertainty, the Township of North Glengarry called on Greyline Instruments to help troubleshoot two permanently installed flow meters.
VITONE ECO decanters, together with all auxiliary machinery such as polypreparers, removal dewatered sludge screws, pumps, etcetera, are meant for the following uses: dehydration and thickening of sewage from civil and industrial purification plants; dehydration of vegetable biomasses and zootechnical sludge; waste water treatment for distilleries and fellmongering waste.
For industrial and municipal treatment plants; Chemical scrubbers, biological towers and adsorption systems to remove hydrogen sulfide, mercaptans, other organic sulfur compounds and ammonia from digesters, pump stations, ponds, grit and screening works, sludge filter presses and dryers. Special Wet Electrostatic Precipitator for sewage sludge incinerators. Stripping ammonia and other volatile compounds. Decarbonization removal of carbon dioxide from wastewater.
Force main systems are typically high sulfide odor generators due to septicity conditions related to full pipe flow and a greater anaerobic slime layer (biofilm) thickness. Primary factors that influence sulfide loading generation in a force main include sewage temperature, BOD, retention time, pipe size and flow. Gaseous hydrogen sulfide (H2S) release at the force main discharge is usually the main concern related to odor and corrosion control needs; however, corrosion problems within the pipe can be of a...
