## Abstract

The invention provides a Bioreactor-Membrane Integrated Technology (B-MIT), comprising an immobilized cellular system bioreactor that initially treats raw water, functionally integrated with a membrane system where the biologically treated water is filtered to generate high quality finished water.

## Claims

### Claim 1

An integrated water processing technology comprising:
one or more immobilized cellular systems in fluid communication with a membrane system comprising one or more membrane units;
each of the one or more immobilized cellular systems comprising a holding tank having a raw water input and effluent output and one or more biological treatment/processing units;
each of the one or more biological treatment/processing units comprising a biological component and a biological support component;
wherein the membrane system receives water from said one or more immobilized cells systems and filters said water to remove contaminants.

### Claim 2 (depends on 1)

The integrated water processing technology of claim 1; wherein the one or more immobilized cellular systems are in parallel or in series.

### Claim 3 (depends on 1)
