Moving bed Bioreactorbull As contaminated water enters the Bioreactor it is slowed down to allow for solids to fall to

the bottom of the tank and evenly coat the biomass Being a moving bed reactor the biomass is systematically rotated allowing all portions of the media to be exposed to the influent These provide the biodigesters an unlimited surface area for bio-reaction to occur Pre-packaged in a liquid form the Hydro-Biodigesters are dispensed automatically into the biomass Automatic dosing allows precise use of the biological product for maximum digestion of waste Water passes from the system automatically where it can be discharged for reuse or sanitary sewer Head pressure purges the accumulated sludge eliminating the requirement to manually remove solids

MBR GEbull The ZeeWeed membrane bioreactor (MBR) process is a GE technology that

consists of a suspended growth biological reactor integrated with an ultrafiltration membrane system using the ZeeWeed hollow fiber membrane Essentially the ultrafiltration system replaces the solids separation function of secondary clarifiers and sand filters in a conventional activated sludge system

bull ZeeWeed ultrafiltration membranes are immersed in an aeration tank in direct contact with mixed liquor Through the use of a permeate pump a vacuum is applied to a header connected to the membranes The vacuum draws the treated water through the hollow fiber ultrafiltration membranes Permeate is then directed to disinfection or discharge facilities Intermittent airflow is introduced to the bottom of the membrane module producing turbulence that scours the external surface of the hollow fibers This scouring action transfers rejected solids away from the membrane surface

MBRbull ZeeWeed membrane bioreactor technology effectively overcomes the problems

associated with poor settling of sludge in conventional activated sludge processes ZeeWeed MBR technology permits bioreactor operation with considerably higher mixed liquor solids concentrations than conventional activated sludge systems that are limited by sludge settling The ZeeWeed MBR process is typically operated at a mixed liquor suspended solids (MLSS) concentration in the range of 8000 to 10000 mgL Elevated biomass concentrations allow for highly effective removal of both soluble and particulate biodegradable material in the waste stream The ZeeWeed MBR process combines the unit operations of aeration secondary clarification and filtration into a single process producing a high quality effluent simplifying operation and greatly reducing space requirements

bull This unique stand-alone Bioreaction system can be placed into almost any Hydrokleen wastewater treatment system This unit will dramatically assist existing treatment systems The HE-BR-500 can be added to any system where light hydrocarbons high concentrations of oils and grease antifreeze pesticides organic nitrogen and other liquids are a problem

Moving bed Bioreactorbull As contaminated water enters the Bioreactor it is slowed down to allow for solids to fall to

the bottom of the tank and evenly coat the biomass Being a moving bed reactor the biomass is systematically rotated allowing all portions of the media to be exposed to the influent These provide the biodigesters an unlimited surface area for bio-reaction to occur Pre-packaged in a liquid form the Hydro-Biodigesters are dispensed automatically into the biomass Automatic dosing allows precise use of the biological product for maximum digestion of waste Water passes from the system automatically where it can be discharged for reuse or sanitary sewer Head pressure purges the accumulated sludge eliminating the requirement to manually remove solids

bull Dual 5500 gallon Bioreactors for use in high-flow wastewater recycling or pre-treatment for discharge to sanitary sewer Bioreaction take time the flow rate and substrate to be broken down determine the size of the system This big guy is 5500 gallons The 5500 can be set up to break down hydrocarbons high concentrations of oils and grease antifreeze pesticides organic nitrogen and other organics Contact us for a quote on your requirement
