AERZEN Rental combines blower technology with innovative aeration technology for maximum efficiency and flexibilityOptimised aeration systems for complex wastewater
For more than a decade, AERZEN Rental supports wastewater treatment plant operators by supplying temporary aeration systems.
A complete wastewater treatment plant is planned In the future, AERZEN Rental is planning to work closely with the AERZEN product line “Wastewater Treatment System” to offer a complete tempo rary AERZEN wastewater treatment system that would include tanks and pumps.
Technical facts:
• Dimensions: 5x2.4m
• SSOTE (Standard Surface Oxygen Transfer Efficiency; the efficiency with which oxygen is transferred into the water under standard conditions): up to 7% per meter
• Connection with the blower through camelock hoses
• Can be on feet or attached to a floater
• Typical accessories: DO probe for determining dissolved oxygen, acid dosing units, hoses and manifolds.
The aeration sets, or grids are the natural extension to the AERZEN blower portfolio, as often a broken blower is a symptom of an aging aeration system rather than an of an aging blower itself. For many years now, AERZEN blowers, combined with the right aeration technology, have been the most efficient solution for the aeration process in municipal wastewater treatment plants. AERZEN also provides customised solutions for industrial customers: to treat wastewater with highly varied compositions – for exam ple, from dairies, refineries and paper mills – the AERZEN Group has expanded its aeration portfolio.
Wide range of different aeration technologies
Now that specialised companies like SUPRAFILT and MESSNER (in Europe), STS and AQUARIUS (in the USA), have joined the AERZEN Group, AERZEN Rental’s customers have access to a wide range of aerators and technologies. In Europe, aerators from both MESSNER and SUPRAFILT were added to the range of products, and AERZEN Rental was able to expand its product range as follows:
• Coarse-bubble stainless steel aerators: for very demand ing effluents, like refineries, or tanks which only need mixing
• EPDM pipe aerators: general use, good all rounder, cost effective to replace
• Silicone pipe aerators: with very good results in dairy industries
• Polyurethane aeration panels: very efficient, the best solution for municipal wastewaters
The grids consist of a stainless steel frame to which the aeration elements are attached. Depending on the appli cation, these can also be fitted with sacrificial anodes (for example, in saltwater applications). The elements can be placed directly on the tank floor or fitted with feet at each corner to clear obstacles or existing pipework or aerators. Alternatively, the elements can be attached to floats if the tank floor or waterways cannot be used.
