For over 29 years the BMS Aerotor® has proved to be an innovative solution to waste water (sewage) treatment in over 250 locations worldwide. The Aerotor® provides a highly efficient, low maintenance, prefabricated, aerobic treatment for small to medium community waste water applications. It is especially suitable where existing equipment is present, e.g. Primary Settlement/Septic Tank, where in-situ construction is envisaged or extra Ammonia Reduction (Nitrification) is required.
The BMS Aerotor is a next generation RBC; it is a combined fixed film reactor and active aeration system mounted on a horizontal shaft with 97% of the surface area inside the drum. The rotational GRP media is in a spiral formation enclosed in outer drum to provide active aeration, intense surface area and net hydraulic lift. The Aerotor is a plug flow system that can easily treat both high and low loads. It in essence has all the advantages of traditional RBC's; low power, maintenance, spare parts and operator input with none of the downsides such as one sided growth on shut down, excess biofilm growth and flow bypass during low and high flows. The Aerotor is a plug and play sewage treatment plant that can be placed above or below ground without the need for a concrete surround and is fully portable and relocatable.
The Aerotor® is designed to treat settled sewage in combination with in-situ or prefabricated primary and final settlement Tankage. It is often used to supplement existing underperforming/overloaded sewage treatment plants or for Ammonia Removal (Nitrification) where it can achieve Ammonia of less than 1 mg/l. The Aerotor can be installed above or below ground without the need for a concrete surround and is a complete plug & play system. It also generates 350 mm of net hydraulic lift from inlet to outlet meaning that it can be installed with minimal changes to existing pipework.
The selection of the optimum unit for any given application may depend on many factors, e.g. influent strength, design flow, existing equipment and final effluent quality required. Please contact us for model selection and quotation and advice.

*Please note the above are average figures, please contact BMS prior to selection. Ammonia removal (Nitrification) is temperature dependent. Higher Nitrification will be achieved in consistently warmer climates and lower in termperate to cold climates.
