Aqua-Aerobic Systems has been designing biological systems since 1969 and has over 1,000 systems installed worldwide. Their suite of biological processes ranges from the tried-and-true Sequencing Batch Reactor (SBR) Technology to the breakthrough AquaNereda® Aerobic Granular Sludge Technology.
This technology is geared towards small-to-medium applications looking to achieve anywhere from rudimentary BOD/TSS removal, all the way to advanced Biological Nutrient Removal (BNR) in a small footprint. Aqua-Aerobic Systems’ SBR is designed as a true batch process, never allowing raw influent to enter the system while treated effluent is being decanted. Their SBR also counts on fully retrievable mixing and aeration equipment, eliminating the need to drain the tanks for equipment repairs.
Aqua-Aerobic Systems is the exclusive provider of the AquaNereda® Aerobic Granular Sludge Technology in North America. This technology, developed in the Netherlands, harnesses the benefits of granular sludge to provide a system that can perform enhanced BNR while using as little as 25% the footprint of conventional activated sludge systems, as well as only consuming 50% of the energy. Aerobic Granules exhibit excellent settling performance and are extremely robust in the presence of fluctuating loading, pH, and toxicity.
Membrane Aerated Biofilm Reactor (MABR) is a unique attached growth biofilm (fixed film) aeration system which allows for low energy delivery of oxygen. The biomass grows on the outer surface of the MABR strands and receives it’s oxygen from the air flowing on the inside of the hollow tubes. This form of aeration is much more efficient than conventional diffused aeration, leading up to 75% less energy consumption for the same amount of treatment. Being a fixed film technology, the MABR also benefits from greater resiliency, and up to a 50% reduction in waste biomass production. The drop in Oxymem MABR module can increase the amount of wastewater that can be treated within an existing conventional activated sludge system, thereby extending the life and capacity of a municipality’s existing infrastructure.
The Moving Bed Biofilm Reactor (MBBR) process is an innovative fixed film (attached growth) biological process. MBBR allows for an extremely small biological system footprint which is robust and easy to maintain. Bacteria grow and thrive on specially designed bio-media with a maximized surface area. These bacteria digest and convert soluble material to biomass which can then be removed downstream using a WWW dissolved air flotation (DAF) unit.
WWW also specializes in the combination of MBBR technology with the Integrated Fixed Film Activated Sludge (IFAS) process for advanced wastewater treatment to meet more stringent nutrient removal limits.
Both MBBR and IFAS are easily retrofitted into existing facilities and can significantly increase the capacity of an existing conventional wastewater system.
World Water Works’ inDENSE system is a gravimetric selection technology that provides a method for retaining the denser biomass while wasting out the lighter fraction of the MLSS in the treatment system. This can lead to improved settling characteristics, increasing process throughput and performance, and has also been shown to promote enhanced biological phosphorus removal.
The inDENSE system utilizes specially designed hydrocylones to select for denser flocs/solids to be recycled while wasting the lighter solids. Designed as a modular system, inDENSE is easily integrated into any existing plant for a low capital cost investment with a rapid rate of return.
