A variety of aeration equipment types are used for effective mechanical oxidation and gas removal. The most common, and most efficient, is positive draft aeration. This is accomplished in cylindrical or rectangular vessels where a counter-current flow of air and water is created.
The STM-Aerotor™ Biological Nutrient Removal (BNR) System uses Integrated Fixed Film and Activated Sludge (IFAS) technology as part of a process that provides biological nutrient removal for municipal and industrial wastewater treatment.
ATOMERATOR™ Iron Oxidation Systems force diffused air into a stream of moving water under pressure in a manner that insures intimate contact between the air and all particles of water. It is ideal for oxidation of ferrous iron which can then be removed by filtration in a pressure type system.
The most recent advancement to surface aerator technology can be seen in the LANDY-7 impeller. The Landy impellers have always incorporated a sturdy design with zero failures due to cracked, sheared, or broken impeller blades. This new impeller increases oxygen transfer efficiency and reduces axial and radial loads. The LANDY-7 provides a ...
As a bottom mounted aerator and with intensive mixing action it is ideal for deep tanks, moderate to high solids concentrations and also re-suspension of settled solids. Available with or without channels and in self-aspirating and blower versions depending on basin dimensions and oxygen demand.
KLEENUP is a soil surfactant with Micro Carbon Technology which promotes a favorable soil environment, improves aeration, and increases the water holding capacity of soils. Through the exchange capacity, KLEENUP sequesters heavy metals and breaks carbon chains to speed up the degradation and breakdown of harmful and toxic chemical residues.
Axial flow aerator with patented instantaneous radial discharge. World renowned for high aeration efficiency in field conditions due to maximum transfer of kinetic energy to water surface. Installations range from small tanks to massive lagoons due to exceptional mixing and oxygen dispersion.
Designed for bridge or platform mounting in basins with fixed or minimal water level variation. Can be installed and removed as a fully assembled unit through a hole in the platform without draining the basin. The length can be manufactured to suit virtually any platform to water level measurement.
Specifically designed for fixed mounting to allow impeller immersion to vary in accordance with flow and associated oxygen demand. Maintains aeration efficiency at variable speed. Four impeller options - 4-blade, to induce circulation in oxidation ditches, and 6-blade, for higher efficiency; LH or RH.
Aspirator aerator featuring a unique impeller and vacuum chamber design drawing air below water level and dispersing as micro-bubbles in any chosen direction. Ideal when aeration and directional flow generation are required in a single unit. Multiple mounting options allow use in any basin geometry.
Separate aerator and mixer motors allow individual or joint operation; ideal for applications requiring oxygen regulation. Joint operation improves overall aeration efficiency, eliminates mixer rails, aligns the impellers on a common axis, to provide complimentary mixing patterns, and reduces mixing energy.
Totally independent aerator and mixer. Blower operation and frequency can regulate oxygen supply from zero to maximum capacity, whilst retaining full mixing and oxygen dispersion capability, therefore ideal for SBR, MBR reactors. Available as submerged drive or surface drive with extended shaft.
Recreational ponds, wastewater lagoons, fish grow-out ponds and small, shallow lakes have always exhibited the problem of organic matter collecting on the bottom and eventually becoming polluted. Wastewater lagoons are especially fraught with problems because their purpose is to clean the wastewater to the point that it can be released back into ...
The Reciprocating Aerator is designed to punch cleaner holes in tough soil without additional weights. As with all Classen turf care products, simplicity is built in with an open design and simple operator controls.
Every modern town or city has a wastewater collection system of some type. The collection system is the conduit for used water, both sanitary and gray (relatively clean, including storm water) water, which initiates at the individual homes and businesses in the community. A primary part of the collection system is a number of “wet ...
For more than half a century, the EcoJet aerator design has provided proven results for municipal and industrial markets throughout the world. With ultimate versatility, no other mechanical aerator is more rugged or more efficient. The EcoJet offers unparalleled performance and superior reliability, low operating costs, and remarkable resistance ...
