The BioBarrier

System, is a membrane bioreactor providing primary settling, fecal coliform, BOD, TSS and nitrogen reduction (if needed)

using aeration and anoxic zones, and membrane filtration. The system is contained in locally supplied tanks, either in a two or three

compartment tank, or multiple tanks, with the membrane module always in the last compartment/ tank of the system. The membrane

module itself consists of flat sheet membranes arranged in a cartridge. A high mixed liquor suspended solids concentration in the aeration

zone provides biological treatment and nitrification. The final effluent or permeate is pulled out by the permeate pump through the MBR

membranes leaving behind large organic and inorganic particles for further digestion or wasting.

If nitrogen removal is not needed the system consists of a tank with two compartments or two separate tanks. The first compartment or

tank provides primary treatment - sedimentation and separation of floatables and solids, and is equipped with an outlet screening device

called SaniTEE

. From this screened compartment or tank, the wastewater will flow into the second compartment or tank, which is the

aeration/membrane zone.

If nitrogen removal is needed the system consists of a tank with three compartments, or two tanks totaling at least three compartments,

with exactly two compartments in the second or final tank. The first compartment or tank provides primary treatment - sedimentation and

separation of floatables and solids, and is equipped with an outlet screening device called SaniTEE

must be in the same tank, and the second compartment is where denitrification takes place under anoxic conditions. The third

compartment, the aeration/membrane zone, is separated from the anoxic zone by a baffle wall between the two zones to allow nitrified

waste to enter into the anoxic area for denitrification.

NSF Standard 350 Class R

The BioBarrier

system has been tested under NSF Standard 350 Class R (Residential) and is capable of treating residential wastewater

for restricted indoor urban water reuse, which is toilet and urinal flushing. The system design requires a holding tank and plumbing system

for reuse water and shall meet all applicable codes; have proper backflow prevention and protection against cross connections; and is the

responsibility of the local designer/installer. When the reuse water is used for toilet and urinal flushing, additional disinfection should be

considered to provide adequate assurance in preventing microorganism growth in the treated reuse water storage tank and as required by

applicable codes.

The reuse tank shall be located after the BioBarrier

to be dispersed in a locally approved soil dispersal system or released into a sanitary sewer system. A potable water make up system

shall also be available to supply water when treated reuse water is not available. This potable water make up system shall include a

properly designed backflow preventer that meets all applicable codes.

NSF Standard 350 Class R

The BioBarrier® system has been tested under NSF Standard 350 Class R (Residential) and is capable of treating residential wastewater

for unrestricted outdoor urban water reuse, which is acceptable for use in surface and subsurface irrigation, including irrigation of edible

crops without the edible portion being in direct contact with the treated water. A reuse tank may be required if the irrigation system

requires it. The holding tank and plumbing system for reuse water shall meet all applicable codes; have proper backflow prevention and

protection against cross connections; and is the responsibility of the local designer/installer. Additional disinfection should be considered
