Abstract
This application relates to an oxygen infusion module for a system and method of treating wastewater wherein an oxygen infusion system is used to supersaturate wastewater before aerobic biological processes, wherein oxygen is transferred to the wastewater free of oxygen bubbles and achieves a reduction in power demand for the aeration process of wastewater.
Claims22
An oxygen infusion module, comprising:
- a housing;
- a central tube that extends along an axis of the housing;
- a top plug attached to a proximal end of the housing;
- a bottom plug attached to a distal end of the housing;
- a plurality of hydrophobic hollow microporous fibers disposed in the housing and suspended from a disc and arranged about the central tube, the hydrophobic hollow microporous fibers having a length shorter than a length of the housing, each of the hydrophobic hollow microporous fibers having a longitudinal bore and a plurality of micropores on a circumferential wall about the longitudinal bore;
- and
- a vent in fluid communication with the central tube and with a space inside the housing about the central tube, the vent being configured to vent undissolved oxygen and nitrogen from the oxygen infusion module,
- wherein the oxygen infusion module is configured to receive a flow of pressurized oxygen from an oxygen source so that the plurality of hydrophobic hollow microporous fibers receive the pressurized oxygen from the oxygen source through the longitudinal bore thereof,
- wherein the oxygen infusion module is configured to receive a flow of wastewater such that the wastewater flows through the central tube and into the housing so that it comes in contact with the circumferential wall of one or more of the plurality of hydrophobic hollow microporous fibers so that the pressurized oxygen is transferred to the wastewater through the plurality of micropores such that oxygen transfer to the wastewater occurs free of oxygen bubbles in the wastewater, the oxygenated wastewater discharged from the housing via one or more distal openings and via the bottom plug.
6 more elements
An oxygen infusion module, comprising:
- a housing with one or more openings on a sidewall of the housing via which wastewater enters the housing;
- and
- a plurality of hydrophobic hollow microporous fibers disposed in the housing and suspended from a disc, each of the hydrophobic hollow microporous fibers having a longitudinal bore and a plurality of micropores on a circumferential wall about the longitudinal bore,
- wherein the oxygen infusion module is configured to receive a flow of pressurized oxygen from an oxygen source so that the plurality of hydrophobic hollow microporous fibers receive the pressurized oxygen from the oxygen source through the longitudinal bore thereof,
- wherein the oxygen infusion module is configured to receive a flow of wastewater via the one or more openings in the sidewall of the housing such that the wastewater comes in contact with the circumferential wall of one or more of the plurality of hydrophobic hollow microporous fibers so that the pressurized oxygen is transferred to the wastewater through the plurality of micropores such that oxygen transfer to the wastewater occurs free of oxygen bubbles in the wastewater, the oxygenated wastewater discharged from the housing via a distal end of the housing.
