Benefits of technology

The invention has advantages and new features that are described in the text. These advantages and features may be realized through the use of the invention or may be discovered through routine experimentation.

Problems solved by technology

However, only 2.5 percent of the water found on Earth is considered fresh water (i.e., is not salt water or brackish water; both of which are unfit for human consumption).
Contaminated waters are detrimental to the environment and public health.

Abstract

Described herein are systems and methods for treatment of contaminated water employing a mobile supported biofilm. The treatment systems include a bioreactor, a mobile biofilm disposed within the bioreactor, and a solid-solid separation unit attached to the bioreactor. The solid-solid separation unit is adapted to receive an effluent stream from the bioreactor, wherein the effluent contains the mobile biofilm, and separate at least a portion of the mobile biofilm from the effluent and return it to the bioreactor.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of priority to U.S. Application No. 62 / 001,241, filed May 21, 2014 and entitled BIOFILM MEDIA TREATMENT SYSTEM, AND METHOD OF TREATMENT, which is incorporated herein by reference for all purposes as if fully set forth herein.JOINT RESEARCH AGREEMENT[0002]The subject matter claimed herein was made as a result of activities undertaken within the scope of a joint research agreement.
