Its ability to reduce biochemical oxygen demand (BOD5), total suspended solids (TSS), nitrogen and phosphorus makes Lotus-ActiveCell an effective solution to a variety of regulatory treatment standards.In a Lotus-ActiveCell MBBR, microorganisms attach themselves to submerged moving plastic media, forming a biofilm. Air is transferred into the water, mixing the media and water and providing oxygen to the bacteria. The biofilm absorbs, oxidizes and reduces organic and inorganic material thus providing treatment. Hydroxyl’s ActiveCell450TM Biofilm Carrier (media) is the core technology behind the Lotus process. It’s excellent oxygen transfer and large biofilm attachment area enable compact efficient designs. Lotus-ActiveCell is available in a variety of materials and tank geometries. Reactors can be constructed of stainless steel, fiberglass or concrete and can be installed above or in-ground. The systems are custom designed to fit the specific requirements of your site.Lotus-ActiveCell is easy to install, cost effective to operate and requires minimal maintenance. In attached growth reactors, the concentration of bacteria in the biofilm is self regulating and produces minimal sludge. These characteristics eliminate the need to actively manage mixed liquor suspended solids (MLSS), food to mass (F/M) ratios and return activated sludge (RAS).

Effluent is reused for irrigation.LOTUSTM - ActiveCellTM- ActiveCell450TM Biofilm Carriers are constructed of UV resistant polyethylene plastic giving them durability and a long life span regardless of the application. Their neutral buoyancy in water is critical to effective mixing within the reactor basin and ultimately provides an increase in treatment efficiency. ActiveCell450 Biofilm Carriers have a large internal protected surface area for biological growth. The apertures are engineered to allow for adequate scouring velocities and sloughing before biological bulking occurs.Stainless steel aeration grids Stainless steel retention screensRepresented by:259A Samuel Barnet Blvd. ?

Thus, Lotus-ActiveCell reactors are designed with multiple stages and chambers depending on the level of treatment that is required. Aerobic stages rely on the transfer of oxygen not only for treatment but to effectively mix the media, water and organic material. Other stages implement processes that take place in the absence of oxygen (anoxic denitrification). In these stages the media and water are mixed mechanically.ActiveCell450TM Biofilm CarriersThe free-floating ActiveCell 450 Biofilm Carriers are constantly in motion and mixing in the basin as air compressors and stainless steel aeration grids ensure a uniform distribution of oxygen into the base of the reactor.Cylindrical stainless steel wedgewire screens are installed vertically or horizontally to retain the free-floating media within the biological reactor.ActiveCell450TM Biofilm Carriers Media Retention ScreensInfluent Treated Effluent Secondary ClarifierSecondary SludgeLOTUS-ActiveCell Reactor BasinActiveCellTM and ActiveCell450TM are registered trademarks of Hydroxyl Systems, Inc.22 mm
