UltraCell™ combines MBBR and ultra filtration processes without a need for a secondary clarifier or a DAF to remove bulk of the TSS. Typically, a biological treatment system is followed by a secondary solids separation process and a tertiary filtration step to produce reuse quality water. Headworks has developed the UltraCell™ product with an extensive pilot study of its MBBR process with a ceramic membrane (ultrafiltration). Due to the very low TSS in the MBBR process relative to the membrane bioreactor (MBR), the UltraCell process requires minimal power and cleaning chemicals. Moreover, the flux rate through the membrane is increased by a factor of 4, thereby quadrupling the lifetime of the membranes. The overall capital and operating costs of the UltraCell process are significantly lower than the MBR process, while the footprint of both processes is approximately the same.
