Title: Modular Shipboard Membrane Bioreactor System for Combined Wastewater Stream
Inventor: BEHMANN HENRY
IPC: C02F1/74
Filed: 1993-08-19
Abstract: Raw sewage ("black water" from toilets), wastewater from showers, sinks, kitchen facilities ("grey water") and oily water from the bilge of a host vessel ("oily water"), in combination, unexpectedly provide the essential nutrients for a live mass of mixed microorganisms which are peculiarly well-adapted to ingest the nutrients. To facilitate availability of oxygen to the microorganisms as to provide growth of the microorganisms, and also, to allow them destroy to themselves, excess oxygen is discharged, in a combination of microbubbles and macrobubbles, into a membrane bioreactor ("MBR"). The mixture of bubbles is preferably generated with coarse (>2 mm) and fine (< 20µm) bubble diffusers. An auxiliary stream, whether alone, or a recirculating stream into which air is drawn, may provide the coarse bubbles. The air is entrained, in a jet aerator or eductor, in a recirculating loop of activated sludge taken from the MBR. Another portion of the contents of the MBR is pumped to a semipermeable membrane which provides water (permeate) of excellent quality. The remaining concentrate is led to a gas micronizing means which produces a tail-jet of microaerated concentrate. The tail-jet is returned to the MBR to provide kinetic energy for maintaining a high velocity of liquid flow in the MBR. A portion of the concentrate is disposed of. Preferably the liquid waste to be treated on-board does not substantially exceed about 21 meters3/day.

Patent CA-2138818-A1 (CA)
Inventor: JANISZEWSKI THOMAS J
IPC: G10L21/02
Filed: 1994-12-22
Abstract: A method and apparatus for improving sound quality in a digital cellular radio system receiver.  A voice activity detector uses an energy estimate to detect the presence of speech in a received speech signal in a noise environment.  When no speech is present the system attenuates the signal and inserts low pass filtered white noise.  In addition, a set of high pass filters are used to filter the signal based upon the background noise level.  This high pass filtering is applied to the signal regardless of whether speech is present.  Thus, a combination of signal attenuation with insertion of low pass filtered white noise during periods of non-speech, along with high pass filtering of the signal, improves sound quality when decoding speech which has been encoded in a noisy environment.
