Water Treatment
Mixers for Water and Wastewater Treatment
Water resource management has increasingly become a primary focus of communities around the world. This is due to population growth and better understanding of the health concerns associated with the quality of potable water, and the proper treatment of wastewater. Water as a limited resource can meet the needs of the society and nature by means of water reuse and implementation of modern technologies.
Mixtec designs and builds a broad spectrum of mixers for use in water and wastewater treatment. With
hundreds of municipal installations in operation, Mixtec offers a solidly built system for any treatment
need from flocculation, anoxic and anaerobic mixing to anion exchange processes.

A highly
efficient drive and shaft design results in considerable cost savings both in capital costs and
operation cost.

Anoxic Denitrification mixers are used in the suspension growth denitrification processes. Facultative bacteria uses organic carbon in the waste as both a carbon and energy source. Nitrate is used as an electron acceptor in energy metabolism. Through bacterial action, bacteria first reduces nitrate to nitrite and then to nitrogen, which is released as a gas. The denitrification reactor is generally covered to minimize oxygen absorption from the atmosphere. Proper venting is necessary to release generated gases.
Anaerobic digester mixers are used to stabilize sludges, through the decomposition of organic and inorganic matter in the absence of oxygen. The sludge is converted biologically, producing a variety of end products including methane and carbon dioxide. Most of the waste is converted to methane gas, which is combustible, therefore a useful end product.
Flocculation is a highly shear sensitive mixing application in water and wastewater treatment industries. Unlike most other mixing applications, a flocculator's function is simply to maintain the water in motion allowing for the coagulation of the particles to proceed. Our impellers have been developed and refined to minimize shear and turbulence while maximizing pumping capacity to insure proper flocculation.
Lime Slurry
Lime, in slurry form, is used for pH adjustment or softening in water and wastewater treatment plants. We are capable of designing lime slurry mixers for all slurry concentrations and slurry specific gravities.
Carbon Slurry
A typical design consists of one agitated tank with a pH probe located in the outlet line controlling a metering pump, feeding either acid or caustic into the tank's influent line. The objective of the mixer is to provide instantaneous mixing of the influent streams and the tank contents.
Polymer and coagulant aids are used in both water and wastewater treatment plants. They may be either organic or inorganic, and supplied as concentrated liquids. Our Polyelectrolyte mixers are specialized to account for the wide variations in forms, concentrations, and viscosities inherent to this mixing application.
Reagents are widely used in most mining applications and require differing mixing intensities.
Mixtec is familiar with most reagent mixing requirements and can provide various mixer types to suit the applications requirements.
Scum, consisting of oil, grease, soap, pieces of wood, hairballs and vegetable debris, corn, and the like are removed from the surface of primary clarifiers and settling tank by skimming or decanting. It is transferred to a holding tank where, depending on its characteristics, it is diluted and treated with other chemicals. It is then pumped back into the main sludge system prior to thickening and drying.
Mixers are frequently used in sludge storage chambers to maintain solids in suspension prior to thickening or dewatering and to blend conditioning agents into the suspension. Sludge mixer chambers can receive a variety of sludges from different locations in the water treatment process, including: primary, secondary, waste activated, raw septage, and thickened sludges.
The AS700 is specifically designed for waste water treatment applications and features a unique anti-snagging geometry to avoid harmful rag entanglement. The swept back blades and "bolt-free" one-piece design gives the minimum purchase for entangling bodies. The combined axial and radial flow generated by this impeller gives effective floor scouring, even in open basins.
