摘要： A cord for supporting a biofilm has a plurality of yarns. At least one of the yarns comprises a plurality of hollow fiber gas transfer membranes. At least one of the yarns extends along the length of the cord generally in the shape of a spiral. Optionally, one or more of the yarns may comprise one or more reinforcing filaments. In some examples, a reinforcing yarn is wrapped around a core. A module may be made by potting a plurality of the cords in at least one header. A reactor may be made and operated by placing the module in a tank fed with water to be treated and supplying a gas to the module. In use, a biofilm covers the cords to form a membrane biofilm assembly.

摘要： Methods and apparatuses for treatment of contaminated liquid are provided including an integrated ultra-filtration and clarification apparatus, and an optional integrated electrocoagulation capability. The integrated apparatus comprises an outer tank, an inner casing, and a plurality of ultra-filtration filters contained within the inner casing. Clarification of liquid occurs in the gap between the casing and tank. Solid matter settles, and aggregates in the bottom portion of the tank. The accumulated solid material acts as a secondary filter by pre-filtering the liquid prior to contact with the ultra-filtration filters. Clarified liquid is retained in a chamber of the casing, and the clarified liquid is drawn through the ultra-filtration filters as initiated by a source of vacuum communicating with the ultra-filtration filters. The integrated apparatus can be incorporated within any desired liquid treatment facility, and one combination in accordance with this system of the present invention includes an upstream electrocoagulation unit and a downstream reverse osmosis unit. The electrocoagulation function may be incorporated in the tank by a plurality of reaction plates or blades mounted to the interior sidewall of the tank. Additionally, the integrated apparatuses may include bacterial treatment in which a selected group of micro-organisms are introduced into the apparatus for treatment of particular contaminates.

摘要： A system for saturating a liquid with a gas followed by bubble-less delivery and mixing of the gas-saturated liquid into a gas-unsaturated liquid wherein a biological process is occurring. The system comprises a gas-saturation unit which controllably communicates with a bioreactor unit containing a gas-unsaturated liquid wherein a biological process is occurring. The gas saturation unit comprises a sealable pressure-resistant vessel for receiving therein an unsaturated liquid and wherein the liquid is saturated with a gas under pressure. The rate of introduction of gas-saturated liquid into the bioreactor unit is controllable to make it equivalent to the rate of gas consumption by the biological process occurring in gas-unsaturated liquid contained within the bioreactor unit. The invention is particularly useful for bubble-less gas delivery to open and closed bioreactor configurations for wastewater treatment processes.

摘要： A membrane supported biofilm reactor uses modules having fine, hollow fibers, for example, made from melt spun thermoplastic polymers treated after spinning to increase their permeability to oxygen, used, for example, in tows or formed into a fabric. In one module, one or more sheets of the fabric are potted into a module to enable oxygen containing gas to be supplied to the lumens of the hollow fibers. Various reactors and processes, for example to treat wastewater, using such modules are described. In one process, oxygen travels through fibers, optionally through an attached biofilm, to oxygenate surrounding water. Mechanical, chemical and biological methods, for example endogenous respiration, are used to control the thickness of the biofilm.
