Aerators (Water)
WesTech - Cascading Aerator
Cascade Aerators induct air into a water flow in order to oxidize iron and reduce dissolved gases.
WesTech - Forced / Induced Draft Aerator
A variety of aeration equipment types are used for effective mechanical oxidation and gas removal. The most common, and most efficient, is positive draft aeration. This is accomplished in cylindrical or rectangular vessels where a counter-current flow of air and water is created.
WesTech - ATOMERATOR™ Iron Oxidation System
ATOMERATOR™ Iron Oxidation Systems force diffused air into a stream of moving water under pressure in a manner that insures intimate contact between the air and all particles of water. It is ideal for oxidation of ferrous iron which can then be removed by filtration in a pressure type system.Wastewater Aerator
WesTech - Landy 7 Surface Aerator
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.
WesTech - STM-Aerotor™ Biological Nutrient Removal (BNR) System
The STM-Aerotor™ Biological Nutrient Removal (BNR) System uses Integrated Fixed Film and Activated Sludge (IFAS) technology as part of a process that provides biological nutrient removal for municipal and industrial wastewater treatment.
Anaerobic Digestion
WesTech - Digester Covers
WesTech anaerobic digester covers are ideal for new and retrofit installations. These custom covers are innovatively designed by WesTech engineers who have decades of experience meeting customer specifications for biogas and odor containment. Incorporating the most current structural standards, WesTech covers are economical and easy to install.
WesTech - ExtremeDuty™ Sludge Mixer
WesTech ExtremeDuty™ Sludge Mixers provide vigorous mixing of digester contents to prevent stratification and improve the anaerobic process. They reliably speed gas production while reducing foaming and scum accumulation. This rugged design was originally developed to reduce the high service costs of egg-shaped digester mixers. It has proven to be so reliable that the ExtremeDuty Sludge Mixer is now used for maximum efficiency and durability in all WesTech digester mixing applications.
Biological Treatment
WesTech - Ana-Flo™ Reactor
Overview of the Ana-Flo Reactor, Configured as an Upflow Anaerobic Sludge Blanket System: The Ana-Flo™ reactor produces biogas with a high concentration of methane. When this byproduct is captured, it can be used as an energy source to generate electricity for the plant or to put back in the grid, providing customers with equipment that does double duty. The Ana-Flo, a methanogenic (methane producing) reactor configured as an upflow anaerobic sludge blanket (UASB) system, can be used as a pretreatment stage for waste streams with elevated levels of BOD and COD. It works by consuming the influent carbon in a temperature-controlled environment under the absence of oxygen. The byproducts are a treated effluent and usable methane gas. WesTech offers further treatment options for the effluent, such as aerobic treatment for further reduction of BOD/COD, nutrient removal steps, or capture and storage of the biogasproduced by the Ana-Flo.
WesTech - BioDoc™ Trickling Filter Rotary Distributor
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.
