CLARIFIERS
Lakeside Spiraflo
The Spiraflo clarifier from Lakeside is a peripheral feed clarifier designed for the removal of suspended solids in a primary, secondary or tertiary clarification system. Wastewater enters the outer perimeter of the clarifier tank and is directed along the narrow raceway formed by the skirt and the outer wall. This flow pattern dissipates the wastewater’s hydraulic energy as it flows around the raceway, eventually spiraling down underneath the skirt and into the main settling area. The flow travels inward from the skirt toward the center of the tank, coinciding with the direction of the sludge, and the clarified water rises into the centrally located effluent weir trough. The combination of the spiraling flow pattern and the skirt eliminates all possibility of short-circuiting and provides better utilization of the total tank volume for more effective settling. 630-837-5640; www.lakeside-equipment.com
Smith & Loveless Model R OXIGEST
The Model R OXIGEST treatment system from Smith & Loveless provides stable operation and flexible process options for high-strength wastewater or larger flows up to 5 mgd. The field-erected design encompasses complete aeration, clarification and advanced treatment processes while allowing these units to be individually separated and controlled. The system achieves advanced nutrient removal and produces pristine effluent quality suitable for water reuse and direct or indirect discharge. Its concentric tankage maximizes space efficiency in its footprint, thereby preserving facility land for other key plant operations. Multiple aeration zones can be employed to provide specific activated sludge processes for desired treatment levels, including multistage aeration, complete mixed, plug-flow and nitrification/denitrification. Integral treatment process steps can include grit removal, flow equalization, reaeration, tertiary filtration, chlorination, dechlorination and sludge storage. 800-898-9122; www.smithandloveless.com
COATINGS AND LININGS
AGRU America Sure-Grip
Sure-Grip liners from AGRU America are made of HDPE, HDPE-el, PP, PVDF or ECTFE, and serve as a long-term alternative to spray-applied concrete protection products. The liners prevent concrete corrosion and degradation, can substantially extend the lifetime of a structure, and by preventing exfiltration and infiltration, provide direct protection for the environment. The liners have anchoring systems that enable construction in areas of significant backpressure. Unlike spray-applied liners, which have to be reapplied regularly due to cracking or delamination, these liners are long-lasting, and are designed to avoid the residuals cost often associated with concrete spray-on liners, which require tank emptying and cleaning every few years for reapplication. 843-546-0600; www.agruamerica.com
PPG Protective & Marine Coatings RAVEN 405
The RAVEN 405 wastewater treatment coating system from PPG Protective & Marine Coatings has high physical strength and broad chemical resistance to stand up to severe, caustic environments. This ultra-high-build epoxy lining system has Severe Wastewater Analysis Testing certification and passed the Pickle Jar Test, as its thick film can withstand high hydrogen sulfide gasses and other caustics, chemicals and acids found in a wastewater facility. Applications include concrete wastewater lining, clarifiers and digesters, tunnels and pipelines, tanks, secondary containment and manholes. Benefits include corrosion resistance, 100% solids, ultra-low VOC (0.52 g/L), adhesive strength and quick return-to-service. It can protect new concrete or help rehabilitate an existing structure. 888-977-4762; www.ppgpmc.com
DIGESTERS/COMPONENTS
Anaergia Omnivore
The Omnivore is Anaergia’s high solids approach to anaerobic digestion. It incorporates advanced mixing and robust thickening systems to convert low-solids digesters into high-solids digesters (5 to 8%). It adapts to take on increased sludge loading without requiring new construction and supercharges biogas and energy projects by enabling co-digestion of high-strength waste. The system consists of a screw thickener combined with the OmniMix, a high-performance submersible mixer that delivers 30,000 gpm of flow, with a connected load of only 12.5 kW and an average power draw of 6kW and can mix solids up to 12%. It features a gearless direct drive motor and a dynamic mixer that allows operators to adjust the mixer position to break up floating layers and re-suspend grit. The service box lets operators access the mixer without taking the digesters out of service, streamlining O&M. 866-978-9785; www.anaergia.com
Hydro-Thermal Non-Obstructing Heater
Hydro-Thermal’s Non-Obstructing Heater is suitable for heating and maintaining the digester’s precise temperature (+/- 1 degree F) for improving methane production and sludge stabilization. It also eliminates hot or cold spots in the digester, even during the winter months. It utilizes a small footprint, with direct installation into the existing piping. It is produced using wear and corrosion-resistant metallurgies to withstand grit and highly abrasive materials. Its straight-through design can ensure that rags or wipes do not get caught and plug the heater. With its unrestricted flow there are minimal pressure drops, allowing for a wide range of heating capacity. The heaters have no hot surfaces where burn-on can begin to occur. 800-952-0121; www.hydro-thermal.com
MIXERS
Ixom Watercare GridBee and SolarBee Floating Wastewater Mixers
GridBee and SolarBee Floating Wastewater Mixers from Ixom Watercare are designed to solve a variety of municipal and industrial wastewater quality problems including high energy costs, EPA discharge permit violations and odor control. Not only can these powerful mixers operate 24/7 to improve overall treatment, they can also supply most of the mixing energy required in any treatment pond, which in turn can reduce the operational hours of the existing aeration/mixing system. Available power options include fully grid, fully solar and combined grid-solar. Applications include wastewater ponds, activated sludge, water reuse/effluent storage ponds, and anaerobic ponds. 866-437-8076; www.ixom.com
JDV Equipment Nozzle Mix System
The Nozzle Mix System from JDV Equipment is a dual-zone mixing technology that provides uniform mixing patterns that produce even distribution and a stable environment. It can help optimize solids suspension and contact to promote efficiency in a wide range of applications. The system is designed with pumps installed outside the tanks to facilitate ease of maintenance. The pumps are typically chopper pumps or pumps incorporating in-line grinders that prevent fibrous materials from accumulating and causing plugging problems. The application dictates which type(s) of the many varied pump options can be used. The high-velocity nozzles are mounted inside the tank and are oriented to discharge in a flow pattern that completely mixes the tank contents. 973-366-6556; www.jdvequipment.com
Vaughan Turbo-S Mixer
The Turbo-S Mixer from the Vaughan is a small, powerful propeller mixer that is mounted vertically inside an 18-inch elbow and is capable of mixing a pit with just 2 feet of liquid above the floor. It incorporates an upper cutter above the propeller to stop wrapping and fibrous material binding to protect the mechanical seal. It can be used in dairy manure mixing and in municipal treatment plant anoxic zone mixing and oxidation ditches. It can be quickly implemented in primary influent channels, Bardenpho basin mixing, scum blanket mixing and primary sludge storage mixing. Additionally an optional turntable can allow it to be easily re-aimed in the pit. 888-249-2467; www.chopperpumps.com
