  • Force Main Systems Sulfide Odor Control with Hydrogen Peroxide

    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 concern (e.g. "crown cutting") at locations where air pockets can lead to concentrated H2S gas build up. Some basic considerations for assessing an appropriate sulfide odor treatment method for force main systems include: Retention time / duration of control Pump station type / cycling (e.g. vfd; start/stop, etc). Force main injection tap points, if any (e.g. air relief valves) Existence of intermediate re-lift stations or in series pump stations Manifold force main systems

  • Trenchless solutions for the wastewater sector

    TRIC introduced sewer lateral pipe bursting to the underground utilities industry, and since then we have expanded our patented method to larger municipal sewers in all types of situations. From a two-inch laundry line to a 14-inch sewr main, we’ve got what it takes to make it happen quickly, with as little disruption as possible on and under the surface.

  • Carbon black from tyre pyrolysis plant

    Carbon black is another main product of waste tyre/plastic pyrolysis plant processing, which has high heating value and reinforcement function features. 1.Carbon black of waste tyre /plastic pyrolysis plant can be sold to cement factories to be added to cement as a mixture for the replacement of coal and ash partly. 2.The carbon black of waste tyre/plastic pyrolysis plant can be used as heat source to heat the Reactor, it even has a little higher heating value than coal. We can further process carbon black into pellets as a heating fuel instead of coal. Our customers use the carbon black pellets to heat pyrolysis plant or sell to cement factories, steel factories, glass factory, brick factory and so on. 3.With a milling machine, carbon black can be milled into much more fine powder. The carbon black power has reinforcement function to rubber and can be used to make new tyre production, shoe sole, water pipes etc.http://www.wastetireoil.com
