  • Weigh batching: the benefits of an automated system

    In many plants that batch-blend bulk products, weigh batching is a manual, time-consuming operation in which ingredients are weighed individually before being charged to a blender or other process vessel. A significant number of such plants could benefit from the installation of an automated weigh batching system. For small as well as large operations, an automated weigh batching system can pay ...

  • Texas Housing Development

    Burdened with a failing packaged extended aeration system, the Brookeland Freshwater Supply District near Jasper, Texas could not meet the State of Texas effluent discharge requirements. The existing plant also requiredextensive service and maintenance to keep the outdated equipment operational. Left with no other choice, the plant needed to be replaced. The Water District evaluated several ...

  • Design-support and performance estimation using HYDRUS/CW2D: a horizontal flow constructed wetland for polishing SBR effluent

    The 4,000 PE (700 m3/d) wastewater treatment plant at Balf, Hungary was based on sequencing batch reactor technology with phosphorus precipitation as the tertiary step. Its effluent met quality thresholds on average, with above-threshold peaks mainly in winter. The HYDRUS/CW2D model package (PC Progress s.r.o.) was used to simulate the treatment performance of a horizontal flow constructed ...

  • Reduced Sludge Production in BNR Systems: Reality or Myth?

    This paper compares the performance of a pilot Modified Ludzack Ettinger (MLE) process treating degritted municipal wastewater, with full-scale activated sludge plants at two towns in Southern Ontario, namely Listowel and St. Marys. At Listowel, the MLE process achieved superior effluent quality compared to the full-scale extended aeration system at a total bioreactor HRT of 20 hours versus 48 ...

  • The most efficient distance between two points

    When bulk material characteristics, process parameters or space restrictions call for a flexible screw conveyor Deciding on the single most efficient method to move your material from point A to point B is a matter of simple deduction: just match your material flow characteristics, process parameters and space limitations to the performance windows and dimensional restrictions of ...
