Abstract: An apparatus is described for withdrawing filtered permeate from a substrate contained in a reservoir at ambient pressure. The apparatus includes a plurality of membrane assemblies. Each assembly has a plurality of hollow fiber filtering membranes, immersed in the reservoir, at least one permeating header with the membranes sealingly secured therein, and a permeate collector to collect the permeate sealingly connected to the at least one permeating header and in fluid communication with lumens of the membranes. The membranes of each assembly extend generally vertically upwards from a first header during permeation. One or more sources of suction are provided in fluid communication with the lumens of the membranes of each assembly through the permeate collectors and apply sufficient suction to withdraw permeate from the lumens of the membranes. An aeration system for discharging bubbles assists in keeping the membranes clean. In other aspects, a method of removing fouling materials from the surface of a plurality of porous membranes includes providing, from within a membrane module, gas bubbles in a uniform distribution relative to the membranes. The bubbles move past the surfaces of the membranes to dislodge fouling materials from them. The membranes are arranged in close proximity to one another and mounted to prevent excessive movement.

Abstract: A method of cleaning ultrafiltration or microfiltration membranes reduces the rate of decline in the permeability of the membranes so that intensive recovery cleaning is required less frequently. In one aspect, cleaning events using a chemical cleaner are started before the membranes foul significantly and are repeated between 1 and 7 times per week. The product of the concentration of the chemical cleaner expressed as an equivalent concentration of NaOCl and the duration of all cleaning events is between 2,000 minutes·mg/l and 30,000 minutes·mg/l per week. When performed in situ, each cleaning event comprises (a) stopping permeation and any agitation of the membranes, (b) backwashing the membranes with a chemical cleaner in repeated pulses and (c) resuming agitation, if any, and permeation. The pulses last for between 10 seconds and 100 seconds and there is a time between pulses between 50 seconds and 6 minutes. Each cleaning event typically involves between 5 and 20 pulses. In another aspect, cleaning events using a pulsed backwash of heated water are similarly started before the membranes foul significantly and are repeated between twice a day and once every two days.

Abstract translation: 清洁超滤或微滤膜的方法降低了膜渗透性的下降速率，因此需要较少的密集回收清洁。 在一个方面，使用化学清洁剂的清洁事件在膜明显污染之前开始，并且每周重复1至7次。 以NaOCl当量浓度表示的化学清洁剂的浓度与所有清洁事件的持续时间的乘积在每周2,000分钟至每分钟30,000分钟/ mg之间。 当原位进行时，每个清洁事件包括（a）阻止膜的渗透和任何搅动，（b）用重复脉冲的化学清洁剂回洗膜，和（c）恢复搅拌（如果有的话）和渗透。 脉冲持续10秒至100秒，脉冲之间有时间在50秒和6分钟之间。 每个清洁事件通常涉及5到20个脉冲。 另一方面，使用加热水的脉冲反冲洗的清洗事件同样开始之前膜显着污染，并且每天两次和每两天重复一次。

Abstract: A single tank submerged membrane bioreactor for treating feed water having unacceptable levels of ammonia or total nitrogen has both a membrane scouring bubble supply and an oxygenating bubble supply. The membrane scouring bubble supply continuously provides large scouring bubbles to clean the membranes. Permeate is continuously withdrawn from the membranes at a high rate but the large scouring bubbles do not transfer sufficient oxygen to the mixed liquor to create aerobic conditions in the reactor. The oxygenating bubble supply is operated to provide small bubbles of air or oxygen that intermittently produce aerobic conditions in a significant part of the mixed liquor. Alternating aerobic and anoxic conditions occur in a significant portion of the tank suitable for nitrification and denitrification. The level of dissolved oxygen (DO) or oxygen reduction potential (ORP) in the tank is measured by sensors and determines when the oxygenating bubble supply will be turned on or off between set minimum and maximum time limits.

Abstract: The outer surfaces of hollow fiber membranes in a skein, or a bank or cassette of stacked skeins, are kept essentially free of solids by maintaining a substantially uniform flow of a stream of coarse bubbles through each of plural orifices in an aerator disposed beneath the fibers. Aerators for skeins used in microfiltration of wastewater in a tank are periodically flushed by injecting flushing air into permeate returned to the tank over a short period. The air is injected into returning permeate for less than 1 minute, preferably less than 20 sec so as to produce discrete masses of water which are flowed laterally through the body of the aerator, cleaning its walls and maintaining the orifices essentially free from plugging.

Abstract: A gas-scrubbed vertical cylindrical skein of "fibers" has their opposed terminal portions held in headers unconfined in a modular shell, and aerated with a cleansing gas supplied by a gas-distribution means which produces a mass of bubbles serving the function of a scrub-brush for the outer surfaces of the fibers. The skein is surprisingly effective with relatively little cleansing gas, the specific flux through the membranes reaching an essentially constant relatively high value because the vertical deployment of fibers allows bubbles to rise upwards along the outer surfaces of the fibers. The effectiveness is critically dependent upon the length of each fiber in the skein. That length is in the range from at least 0.1% more than the fixed distance between opposed faces of the skein's headers, but less than 5% greater than the fixed distance. Lack of tension allows the fibers to sway in bubbles flowing along their outer surfaces making them surprisingly resistant to being fouled by build-up of deposits of inanimate particles or microorganisms in the substrate. For use in a large reservoir, a bank of skeins is used with a gas distributor means which has fibers preferably >0.5 meter long, which together provide a surface area >10 m.sup.2. The terminal end portions of fibers in each header are kept free from fiber-to-fiber contact with a novel method of forming a header.

Abstract: A wastewater feed containing an ultimate BOD/COD ratio >0.6 is well-suited for especially acclimated thermophilic and/or caldo-active living micro-organisms ("hot cells") which thrive in an autothermal aerobic (ATA) reaction zone having an ATA bioreactor ("ATAB") operating at substantially ambient atmospheric pressure in combination with a MF or UF membrane filtration device from which a solids-free permeate may be withdrawn. This combination, of ATAB and membrane device is a "membrane bioreactor" (ATA MBR), which operates autothermally with a feed containing biodegradable organic materials having a BOD of at least 5,000 mg/L, preferably at least 10,000 mg/L (10 g/L) with a minor portion of "municipal" wastewater or domestic sewage. Operation of the ATAB, preferably in the thermophilic range from 45.degree. C.-75.degree. C., with constant HRT from 1 to 12 days, is contingent upon maintaining a stable population of live hot cells. Such cells enhance the biokinetics of degradation and allow operation of the ATAB at higher COD loading and a lower concentration of TSS, than would be possible at a lower temperature. A surprisingly high membrane productivity allows production of much less sludge to be disposed of outside the system, than would have to be disposed of with a conventional mesophilic reactor in normal operation with a HRT of less than 24 hr. A combination of an MP MBR with an ATA MBR is highly effective when the MPB produces high BOD concentration mixed liquor for destruction by the ATAB.

Abstract: The invention provides a new method and apparatus for measuring the concentration of ultra-violet light absorbing organic materials liquids, particularly in pure or ultra-pure water, the speed and convenience being such that it is possible to take successive readings with periods as short as ten seconds. The apparatus can be mounted directly in or as a by-pass to a process stream, giving the capability of constant monitoring with virtually instant microprocessor-controlled response to measurements outside a pre-set range. The water to be measured passes upwards in a cylindrical opaque-walled sample cell at the upper end of which is mounted an intense light source, preferably a Xenon flash tube, and at the lower end of which is mounted two transmission photodetectors, which have in front of them respective narrow-band optical transmission filters in the ultra-violet and visible regions. The light source sits on the upper end of a quartz rod which extends into the cell at or below the water inlet and is coaxial with the cell longitudinal axis, the rod serving to direct the light toward the transmission photodetectors. The output from the "visible" photodetector is used to correct the output from the "ultraviolet" photodetector for transmission losses caused by particulates, element fouling and bubbles in the stream. Two reference photodetectors employing two similar transmission filters are disposed close to the flash tube outlet window and their signals are used to correct for variation in the flash tube output.
