WASTEWATER MIXING RESOURCES

  • Vienna’s climate-neutral wastewater treatment plant gets efficiency boost with Sulzer technologies

  • The Memorial Park Pump Station (MPPS) transfers wastewater flows from Memorial Park to Chapel Street WWTP and/or Te Maunga WWTP. It is a large pump station (PS) installed within a 9.0m diameter concrete structure. The pump station is approximately 12m deep, with a 6.5m maximum water depth and split into several compartments.

  • Landlocked, shallow bodies of water such as recreational ponds, irrigation, drinking water and animal waste lagoons have a major problem with flow. The only natural methods of movement in these bodies of water are the slight Coriolis Effect of the earth and wind. Neither of these natural mixing sources is sufficient to allow shallow water bodies to respire and deal with the natural biological degradation of wastes and detritus that eventually form on the bottom. Eventually, external problems will occur – algae begins to form in abundance, odors will emanate from the water due to stagnation, blue-green cyanobacteria will form on the surface and cause more odor and toxicity, and eventually the water is no longer capable of supporting basic aquatic fauna reproduction.

  • To help meet the stringent water quality standards for denitrification, the Colorado Springs wastewater treatment facility has employed (20) 7.5 hp AquaDDM mixers.

  • ​In 2013, operators of the Tomball, Texas Wastewater Treatment Plant were facing increasing maintenance issues with three brush aerators operating in the plant's two-channel oxidation ditch. The aerator failures were threatening to compromise effluent quality and environmental compliance. Tomball needed replacements.​

  • Water storage tanks and reservoirs are a critical component of distribution systems, yet they can pose a significant challenge for water utilities as they often have a negative impact on water quality. Water quality problems can develop due to low turnover and/or inadequate mixing resulting in short-circuiting. While the benefits of maximizing tank turnover to minimize water age are generally understood, it is only recently that extensive research on mixing characteristics of storage tanks has been undertaken that has provided insight on what causes water quality problems and expertise in designing inlet/outlet pipe configurations, or mixing systems, to achieve complete mixing and maintain water quality.

  • The Madison Metropolitan Sewerage District (MMSD) manages regional wastewater service for the Madison, Wisconsin area, providing wastewater collection and treatment for 43 municipal customers including cities, villages, and utility and sanitary districts.

  • The Chicago area is served by a combined sewer network that carries both raw sewage and storm water.

  • Wastewater treatment lagoons were originally facultative in design — shallow, single and multi-cell lagoon systems that counted on wind, sunlight, anaerobic bacteria, and time for the digestion of the organic components of the wastewater.

  • The City of Reno, NV, has long battled the buildup of fats, oils, and grease in the wetwells of wastewater lift stations in the valleys within this high desert city. Recently, the city set out to address the problem and reduce the associated costs.

WASTEWATER MIXING SOLUTIONS

  • Tri-Oval® Oxidation Ditch System

    The Tri-Oval® Oxidation Ditch System, named for our Aire-O2 Triton® in an oxidation oval, is a subsurface complete mix, looped reactor system that is ideal for municipal and industrial wastewater treatment facilities. The energy efficient Aire-O2 Triton TR Series process aerator/mixer, combined with an optimized control strategy, allows for operation at depths as low as 4ft (1.2m) and up to 33ft (10m).

  • Lagoon Commander Mixer

    The Reliant Lagoon Commander Pond/Lagoon Mixer continuously, and slowly, moves water along the bottom of a lagoon/pond, continually mixing the entire water column using a minimum of energy. When compared to standard surface aerators or directional mixers, the Lagoon Commander is more efficient, less costly to operate, and requires minimal maintenance.

  • Model 4140 VIM-OC Vacuum Induction Mixer

    The JCS Industries Model 4140 VIM-OC Vacuum Induction Mixer is a proven and reliable device that utilizes vacuum to safely and effectively induce both gaseous and aqueous chemicals into open channel water stream applications.

  • Submersible Mixer Type ABS RW

    The RW is Sulzer’s standard range of submersible mixers, economical without compromising on reliable design. These compact, versatile submersible mixers are ideal for agitating, blending, mixing, dissolving, and suspension of solids in municipal treatment plants, industry, and agriculture. The RW mixers can easily be fitted to existing guiderails and lifting devices without modification, using our wide range of brackets and adapters.

  • Submersible Mixed Flow Column Pump Type ABS AFLX

    The submersible mixed-flow column pump type ABS AFLX equipped with an IE3 motor is designed for use where large volumes of process water or wastewater containing solid effluent must be pumped up to moderate heads. Premium Efficiency motors combined with efficient three- to five-blade mixed-flow impellers with low NPSH characteristic impeller design, ensure high reliability and efficiency.
