Buildings/Structures
Legacy Building Solutions Tension Fabric Buildings
Combining rigid-frame engineering with the proven benefits of tension fabric membranes, Legacy Building Solutions offers fabric structures that are fully customizable. They utilize a durable rigid frame in place of the hollow-tube, open-web truss “hoop” framing traditionally used for fabric structures. The strength of the structural steel frame provides several engineering advantages, most notably the ability to easily customize buildings to the exact width, length and height required. In addition to long clear spans, the buildings have straight sidewalls that maximize the usable square footage inside the structure. The design allows for much more structural flexibility than traditional fabric structures, including the ability to add lean-tos, mezzanines, sidewall doors and more. The structures are also engineered to provide desired overhangs or handle additional loads for items such as sprinklers and conveyors. 877-259-1528; www.legacybuildingsolutions.com
Clarifiers
Lakeside Equipment Spiraflo Clarifier
Lakeside Equipment’s Spiraflo Clarifier has a peripheral-feed center-feed take-off design that provides the best hydraulic flow pattern for wastewater as it spirals beneath the skirt and into the main settling area. The combination of the spiraling flow pattern and the skirt eliminates short-circuiting and better utilizes the full volume of the tank for more effective settling and seamless removal of solids and impurities. The design is proven to provide the best hydraulic flow resulting in no short-circuiting, no waterfall effect, no sludge creep and superior solids removal. 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
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
Tsurumi Pump AVANT MMR Series
Engineered for reliability, Tsurumi Pump’s AVANT MMR Series submersible mixers are built to meet the needs of wastewater treatment operations. They are used in equalization tanks to prevent solids buildup and waste from becoming septic. They are also essential in the activated sludge process, such as mixing sludge with key microorganisms. Designed with premium efficiency IE3 electric motors, plus EN-GJL-250 cast iron and stainless steel components, they ensure safety and compliance in hazardous conditions. They feature two silicon carbide mechanical seals in the oil chamber. They also feature thermal and leakage sensors to protect the motor and internal components and offer a planetary gear style mixer as well. They are ideal for maintaining solids buildup and other common issues often found in wastewater management. 888-878-7864; www.tsurumipump.com
Pro-Equipment SUBAIR ROTO
The SUBAIR ROTO submersible mixer/aerator from Pro-Equipment is designed to be placed in water/wastewater tanks. It mixes the content by pumping water from the bottom of the tank and ejecting it radially to provide turbulence for mixing. The submersible mixer/aerator is typically placed at the center of the tank, without anchoring, given the radial pattern of turbulence. There is a built-in air inlet to induce air through a stand pipe above the water’s surface. The air inlet can be equipped with an isolation valve to turn the air supply on or off. There is a protective screen/shield that will keep larger debris from damaging the impeller. It is suitable for storage tanks where periodic mixing/aeration is needed. The shield also enables it to be used in MBBR processes that contain free-floating carrier media. 262-513-8801; www.proequipment.com
Scienco/FAST - a division of BioMicrobics SciCHLOR
The SciCHLOR sodium hypochlorite generator from Scienco/FAST - a division of BioMicrobics, is a fully integrated, simple and compact system for small to mid-size municipal water treatment facilities. On-site generation of chlorine produces sodium hypochlorite at a cost that is significantly lower than purchasing from an outside source. It features SciCELL technology with a “multi-pass” design, control panel and recirculation pump to automatically run at the optimum time and extend cell life with power-save shut down if no demand for sodium hypochlorite. Each compact system comes with an integral brine tank, SciCELL unit, control panel and recirculation pump. Key benefits include consistent, on-demand chlorine production, compatibility with all salt types, an integrated compact design, automatic optimized salinity, low-cost and easy-to-replace parts, and simple maintenance/low operating costs. 314-756-9300; www.sciencofast.com
Vaughan Turbo-S Mixer
The Turbo-S Mixer from 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
