Oxidation Ditch – BioLoop

Sanitaire - Xylem Brand- Combining Sanitaire diffused aeration, Flygt submersible mixing and overall process application, as well as instrumentation and process control from Sanitaire and YSI in both new and retrofit applications, Xylem’s Sanitaire Bioloop oxidation ditch delivers up to 50% better energy efficiency, while remaining adaptable to a wide range of flow and loading conditions. The process can also be designed to remove total nitrogen and total phosphorus. Bioloop oxidation ditch delivers up to 50% energy savings compared to mechanical systems. Achieving 7-9 lb. O2/bHP-hr compared to 3.0-3.5 lb. O2/BHP-hr for mechanical aeration systems.  Installations include Independence-KS and Fremont Hills-MO.

Fine Bubble Membrane Disc Diffusers – Sanitaire

Sanitaire - Fine Bubble Membrane Disc Diffusers feature a unique split pattern and slit shapes, which disperse air bubbles in an extremely fine and uniform pattern for high oxygen transfer efficiency. The specially-blended, high grade EPDM elastomer compounds resist degradation that’s common to other membranes, and delivers over 10 years of proven performance. Lower energy consumption and raised operating efficiencies are made possible by the unique membrane shape, integrated O-ring, and top-sealing threaded retainer ring, which eliminates leakage. A highly effective, integrated check valve enables the aeration zones to be easily shut down for air-on/air-off applications.

SBR – ICEAS Continuous Flow

Sanitaire -Xylem Brand - Sanitaire SBR is a continuous flow biological treatment system that provides multiple advantages versus conventional activated sludge and other SBRs. It can operate in continuous mode or true batch for treatment flexibility. Handles peak flows up to 6 times DWF.  Jefferson City, MO selected the advanced Sanitaire SBR to meet current and future objecteivs including its ability to treat peak flows of 60 MGD or 5x the design average flows. “The advanced Sanitaire SBR technology saved nearly 30 percent in project cost and also offers a permanent reduction in operations and maintenance expense.”

Oxidation Ditch – Orbal and VLR (simultaneous nit/denite)

Evoqua  - Oxidation Ditch is a modified activated sludge biological treatment process that utilizes long solids retention times (SRTs) to remove biodegradable organics. Orbal® system with a Concentric Loop™ configuration that creates dedicated zones for specific treatment processes. These treatment zones operate in series which is essential to the simultaneous nitrification-denitrification (SND) process. VLR® Vertical Loop Reactors system are similar to oxidation ditches that have been flipped on their sides. The VertiCel® System utilizes tanks in series design and consists of an aerated-anoxic tank followed by an aerobic tank. Installations include Belton-MO, St. Charles-MO, Columbus-NE and Fort Dodge- IA.

Magnetite Ballasted Biological System – BioMag (Retrofit Existing or New)

Evoqua BioMag - Ballasted biological process to allow WWTP to handle 3x flow and solids loadings, and to operate at longer sludge ages to achieve enhanced nutrient removal, without physically adding tankage to the plant. Magnetite is a dense, non-abrasive, iron oxide mined locally in Missouri  that can be recovered magnetically from the waste activated sludge and reused in the process to maintain an extremely dense, fast settling biomass. Results in a plant with small footprint, low capital, and low operational costs. Easy to incorporate in any type of activated sludge treatment where biological process remains unchanged and BioMag equipment is located in the sidestream location (WAS stream) without impacting main liquid stream in the WWTP.  Ability to with multi-stage treatment processes, to meet TN to ≤ 3.0 mg/L and TP to ≤ 0.2 mg/L without tertiary filters

Ballasted Clarification – CoMag for Enhanced Primary or Tertiary

Evoqua - CoMag is a high rate clarification process utilizing internal recycling of settled solids and small amount of Magnetite (non-abrasive, high specific gravity) for floc formation to allow for less chemical use and  footprints up to 20x smaller than conventional clarification. The CoMag System easily integrates with planned or existing facilities to allow the use of existing clarifiers of any size or type. Applications included treating wet weather flows, phosphorus removal and water re-use.

Oxidation Ditch – Tri-Oval

Aeration Industries -Tri-Oval Oxidation Ditch provides superior wastewater treatment process control and design flexibility of the activated sludge process. Couple this with the cost savings benefits of lower construction, easy installation, and low maintenance — you have a winner in water treatment. The system’s dual-functionAire-O2 Triton® aerators/mixers drive fine bubble aeration and mixing to 33 feet deep and allow for full Biological Nutrient Removal (BNR). Rentals are available to keep your plant compliant. Installation in Farmington, Missouri.

MBR

Kubota Membrane USA Corporation is an MBR system supplier based on the Kubota Submerged Membrane Unit® (SMU). The Kubota SMU was pioneered to treat municipal, commercial and industrial wastewater simply and successfully. A Membrane Bioreactor (MBR) in which Kubota flat sheet SMUs are installed is very compact and enables you to get high quality effluent with low environmental impact.

SBR – AquaSBR

Aqua Aerobic Systems SBR

Aqua Aerobic Systems AquaSBR® Sequencing Batch Reactor provides true batch reactor technology with all phases of treatment accomplished in a single reactor. All components are easily accessible and the advanced decant system ensures optimum quality effluent withdrawal. Independent aeration and mixing provides lower energy consumption. Time-managed operation offers process flexibility with greater handling of hydraulic fluctuations. Floating decanter provides subsurface withdrawal of decant volume. Local installations include Richmond, Missouri and Abilene, Kansas.

 

Complete Mix Activated Sludge – MixAir -Retrievable Diffusers w Mixer (Simultaneous Nit/Denit)

Aqua Aerobic Systems - MixAir is a biological system that allows a single aeration basin to be used since its aeration and mixing is accessible above the water surface. Cyclically operated aeration and mixing promote anoxic/aerobic and anaerobic environments with low energy consumption without having separate anoxic/anaerobic tanks and mixers to provide a 3 Stage Bardenpho-type process. The system features "Retrievable Diffusers" in racks that can be lifted by a davit crane and rotated outside the basin or other aeration devices. Mixing is provided by proven AquaDDM® Direct Drive floating mixers.  This concept allows for fewer aeration basins initially since the facility can have a single aeration basin and add basins with growth. MixAir systems can accommodate low cost construction of a round basin with movable forms or other configuration needed. Installations include LBVSD at Pleasant Hill-MO, Fishing River WWTP and Rocky Branch WWTP in Kansas City-MO, and Sedalia, MO.

Retrievable Aeration with Tube Diffusers – Aqua Aeorobics

Aqua Aerobics - Retreivable Aeration - The system features fine-bubble “Retrievable Diffusers” in racks that can be lifted by a davit crane and rotated outside the basin for maintenance or replacement without taking the aerations system offline.

Surface Aerator – Aire-O2 Aspirator

aireo Aspirating Floating Aerator

Aeration Industries - Aire-O2 Aspirator  This surface aerator creates a vacuum drawing air down the shaft into the water.  The rotating propeller forces water outward horizontally past the end of the shaft at high velocity.  Above the water line, atmospheric air is drawn through intake ports and travels through the hollow drive shaft to be dispersed in a large plume throughout the water. Being diffused into fine bubbles – about 2.0 mm diameter – the oxygen has extended contact time with the water. The size of the plume varies with the size of the aspirator/aerator which can be from two to 100 HP. Properly positioned, these units can create a “flow linkage” that delivers mixing and oxygen dispersion evenly and thoroughly throughout an entire basin regardless of its size or shape. Dead spots are eliminated.

Trickling Filter Media – Brentwood

Brentwood Trickling Filter Media is a structured-sheet media that is largely responsible for the success of performing trickling filters. Unlike outdated rock fill, PVC modules have superior compressive strength and higher void volumes, which are necessary for stacking. Greater specific surface area allows for higher organic loadings and process efficiencies. All Brentwood trickling filter media is fabricated from rigid, self-extinguishing, un-plasticized PVC sheets with UV protection. The material is resistant to rot, fungi, bacteria, acids, and alkalis commonly found in wastewater.
