Bacterial filtration efficiency

Nelson Laboratories Bacterial and Vims Filtration efficiency test. 

As a result of this resorption and the protein binding of plasma biotin, which reduces filtration at the glomerulus, renal clearance of biotin is only 40% of that of creatinine. This efficient conservation of biotin, together with the recycling of biocytin released from the catabolism of biotin-containing enzymes, may be as important as intestinal bacterial synthesis of the vitamin in explaining the rarity of deficiency. 

But due to flotation (bubble-film extraction), the products of bacterial metabolism and the products of bacterial degradation together with other water contaminants are ranoved continuously from recirculation flow through the bubble-film extractor. As a result, another positive feedback is realized in filtration-flotation system. The essence of this effect lies in the inhibition of vital functions of bacteria with increasing microbial metabolite concentration according to the law of chemical kinetics. And in accordance with the same law, bacterial activity is increased as the products of bacterial metabolism are removed from treated water [20]. Thus, we are able to add one more component, namely, AK, to the magnitude (/fj + AK2). The component AK represents the increase in biofiltration efficiency due to bacterial inhibitors removed by means of bubble-film extraction. In such a way, the resulting rate constant of the process takes the form ( fi + AK2 + AKi). 

Alkaline materials are considered biostats in drilling fluids, but for efficient micro-organism kfll, biocides are used. The most readily measurable effect of micro-oiganisms in drilling fluid is their consumption of chemicals, which results in the loss of the desired filtration control and rheological properties. Bacterial cultures can be made from the drifling fluid to determine their presence and populations so that pH adjustments and/or biocide treatments can be regulated.
