UNIVERSITY OF UTAH RESEARCH FOUNDATION - Salt Lake City UT
International Classification:
C02F 3/10, C02F 3/30, C02F 3/20
US Classification:
210615, 210150, 210138
Abstract:
A system and method are provided for removal of undesirable substances from a body of liquid. The system can include an aeration structure having a continuously inclined surface configured to provide an interaction of air bubbles against substantially an entire length of the continuously inclined surface while the air bubbles are moving toward a top of the body of liquid. The continuously inclined surface can be substantially submerged in the body of liquid. A bio-film of diverse bacteria colonies is disposed on the continuously inclined surface, and a high surface area-to-volume structure is located in proximity to the aeration structure, upon which a bio-film of bacteria colonies can be formed. An aeration system is coupled to an air supply system which releases the air bubbles toward a bottom of the continuously inclined surface, such that the air bubbles move along the continuously inclined surface as they rise so as to (i) create a variety of aerobic-anaerobic conditions at the bio-film and (ii) engage the air bubbles in a continuous mixing of a micro climate for the bio-film in response to an orientation of the continuously inclined surface and (iii) provide airlift circulation of water from bottom to top of the aeration structure.
System And Method For Removing Particles From A Treatment Basin
US Patent:
2009018, Jul 23, 2009
Filed:
Jan 16, 2009
Appl. No.:
12/355636
Inventors:
Michael Graham - Bountiful UT, US
Kraig Johnson - South Jordan UT, US
Kraig Johnson - South Jordan UT, US
International Classification:
B01D 24/28
US Classification:
210189
Abstract:
A system and method are provided for removing particulates from a fluid treatment basin. The system can include a first continuously inclined surface configured to be substantially submerged in fluid in the fluid treatment basin. A base can be provided to which the first continuously inclined surface is connected. At least one orifice is formed in the base. In addition, a second continuously inclined surface can be connected to the base on a side opposing the first continuously inclined surface. The second continuously inclined surface may be substantially submerged in fluid in the fluid treatment basin. A discharge conduit can be connected to the orifice in order to discharge fluid and particulates gathered via the orifice.
