AEROBIC GRANULAR SLUDGE – AquaNereda – Aqua Aerobics

AEROBIC GRANULAR SLUDGE - AquaNereda - Aqua Aerobics- Aerobic granular sludge is an advanced biological wastewater treatment technology providing Enhanced Biological Nutrient Removal (ENR) with TN <3 mg/l and TP<1.0 mg/l without chemicals. The performance is equivalent to a 5 stage bar-den-pho process with 1/2 to 1/4 the footprint without recycle flows,  without the related mixers and pre and post anoxic/anaerobic selectors, without clarifiers and filters not required to meet the performance. No moving parts within the reactor and fixed weirs. An aerobic granular biomass is comprised of compact granules that provide several advantages compared to other secondary treatment processes.  With aerobic and anaerobic zones within the granule, nitrification and denitrification process will take place including enhanced biological phosphorus removal will be achieved.

Complete Mix Activated Sludge with FERMENTER – AquaPASS – (Pre and Post Selector Basins with Fermenter for Bio-P & Denitrification optimization)

Aqua Aerobic Systems - AquaPASS process incorporates selector basins both anaerobic and post anoxic with a fermenter to produce VFAs to aid in formation of Phosphorus accumulating organisms.   Equivalent to 5 stage with a RAS concentrator . Available with both fixed diffusers or retrievable diffusers where it is possible to promote single or multiple basins. Cyclically operated aeration and mixing to provide load based proportional power savings. 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. AquaPASS system is designed to meet the new stringent Total Nitrogen (6.9 mg/l) and Total Phosphorus (0.86 mg/l) effluent levels influenced by the Chesapeake Bay Initiative.  Inquire for low Total Nitrogen (TN) Requirement of 8, 5 and 3 mg/l. A key feature to attain low TN is the "Phase Separator Conditioning Stage"  where return sludge is concentrated and fed to the pre-anoxic selector.  Supernatant is returned to staged aeration basins. Designed to provide 140% more treatment capacity in the same footprint as the previous conventional activated sludge system.

Surface Aerator – Aqua-Lator

Evoqua -  ​The Aqua-Lator® surface aerator, introduced in 1963, is considered the first floating mechanical aerator for wastewater treatment applications. The powerful pumping action of the surface aerator transfers oxygen by breaking up the wastewater into a spray of particles, creating more surface area for atmospheric pressure to drive oxygen into the wastewater. At the same time, the oxygen-enriched water is dispersed and mixed, resulting in highly effective aeration for wastewater treatment. An optional accessory for Aqua-Lator Surface Aerators, is the Mist Eliminator® Spray Containment Dome providing mist and spray control for cold temperatures.

Fine Bubble Membrane Disc Diffusers – Evoqua: Envirex

Evoqua: Envirex - Fine Bubble Membrane Disc Diffusers - Evoqua: Envirex- Diamond S Membrane Disc Diffusers is more efficient than a typical 9" diameter diffuser, resulting in better performance and lower energy costs. The proprietary diamond punch pattern provides 10% more slits than a typical membrane, allowing more fine bubbles to be produced. Additionally, the Diamond S Plus diffuser has 45% greater tensile strength than typical membranes for durability and tear resistance and less than 9% extractable oil for improved diffuser life. The diffuser was developed as an improvement to typical membrane diffusers, and to fit other manufacturer’s pod or holder. Existing support plates and retainer rings can be reused.

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.

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.
