Method for adjustment of membrane separation in the membrane bioreactor and the membrane bioreactor serving for the execution of this method

摘要

way of regulating separation membrane in the bioreactor membrane intended especially for use in processes in which appears a strong foulingu phenomenon is of surface membranes of large quantities of substances present in rozdzielanej mixture that renders the process of them are acjonarnym,in which the connector (2) using a pump (3) is supplied to the membrane module retentate and permeate stream (6) of decreasing in value from hints to membranes is of him being drained out, and furthermore, intervals shall be pumped feedback membrane module, the membrane (6) is characterised by thehaving established the maximum time separation between cycles of membrane separation in which rinsing feedback is stepping out of the membrane module (6) stream of decreasing in time values permeate is introduced into reservoir (8a) which nastu0119pn ie is discharged him using a pump (10) with fixed valueand to ensure a constant value permeatu stream discharged from a (8a), the stream with a decreasing value for reservoir (8a) is permeate, in relation to the value of wyprowadzanej in abundance, which is in excess emptied washing a, c zym in the situationwhile maintaining constant in time permeatu stream discharged from a fixed time maximum reservoir (8a) does not fill to raised level activates opru00f3u017cniaju0105ce partially filled container (8a) lavage and subsequently increases the pressure feedback tra nsmembranowe,however, when less than during fixed time interval immediately preceding the time the maximum reservoir (8a) fill to raised level then activates opru00f3u017cniaju0105ce reservoir (8a) lavage feedback and decreasing pressure transmemb ranowe,the adjustment according to the above two patterns is in situations when filling reservoir (8a) to a given level and operated it zapeu0142nieniem lavage feedback is not fixed time interval immediately preceding the predetermined time until the maximum and achieve maximum or possible to obtain pressure transmembranowego.bioreaktor membrane reactor built with a connector (2), which through the pump (3) channel retentatu (4) is connected to a valve (5) transmembranowego module, pressure membrane (6), which in turn is connected permeatu channel (7) in which the mip boost is rinsing system feedback (8),and successively in the stop valve (9) and a pump (10) is characterized by the fact that the system with feedback (8) is a reservoir (8a) which is installed in przesuwnie piston (8b) made him drive attached (8c) and a reservoir (8a) is equipped in the valve odpowietrzaju0105c y (11) and the sensor device, which advantageously is composed of two electrodes (12), konduktometryczneone of which is fixed in the bottom of the reservoir (8a) and the other to a piston (8b).
