  • OxyStream™ Oxidation Ditch
    WesTech - Biological Treatment

    The OxyStream™ Oxidation Ditch system combines slow speed surface aerators with an oxidation ditch design based on site-specific conditions and our proprietary hydraulic model.

    The oxidation ditch has been proven effective in extended aeration applications throughout the world. The extended aeration process provides buffer capacity against variable loading and a clear, predictable effluent. The use of a surface aerator in an oxidation ditch optimizes both oxygen transfer efficiency and pumping capacity.

  • LANDY-7 Surface Aerator
    WesTech - Biological Treatment

    The most recent advancement to surface aerator technology can be seen in the LANDY-7 impeller. The Landy impellers have always incorporated a sturdy design with zero failures due to cracked, sheared, or broken impeller blades. This new impeller increases oxygen transfer efficiency and reduces axial and radial loads. The LANDY-7 provides a guaranteed minimum efficiency of 3.8 pounds of oxygen per horsepower hour. This improved transfer efficiency saves significant operational costs over the life of the equipment. The reduced axial and radial loads increase the life of the drive unit and reduce the size of support structures and beams for the surface aerators.

  • LANDOX Channel Aeration System
    WesTech - Biological Treatment

    The Landox Channel Aeration System combines vertical drum mixers with fine bubble diffusion in an oxidation ditch arrangement.

    The design of the Landox Channel Aeration System separates mixing and aeration into independent operations. This separation allows for power turn-down of aeration given variable influent conditions while maintaining constant mixing. Independent control of the aeration also provides the ability to accomplish simultaneous nitrification and denitrification in the same reactor.

  • BioDoc® Trickling Filter Rotary Distributor
    WesTech - Biological Treatment

    The BioDoc® Trickling Filter Rotary Distributor is a patented system for optimizing the performance of trickling filters. It consists of a motor drive, a programmable logic controller (PLC) and a flexible program of speed variation designed for individual treatment plants. If power to the unit is stopped due to outage or interruption, the motor disengages the gearing, allowing the unit to spin hydraulically until power is restored. With the dosing rate optimized, the trickling filter can become the most efficient process equipment in the plant, and plant performance overall is greatly improved.
