Experimental investigations were conducted to evaluate the performance 01 n"nofillration fOr tertiary level phosphate removal from wastewater. A flat sheet type Oesal-5 thin 5lul nanofi)tration membrane in a plate and frame module, was IJsed. The inIIuc.nce of pressure. initial feed roncentntion, competing compounds, on nanoflllration performance were determined. TIlecxperimelltal study range o...

In feedstocks containing high ammonia (NH3) concentration, removal of the NH3 during anaerobic digestion (AD) process can improve AD performance. present study, effect using gas-permeable membrane (GPM) technology on performance and biogas production was investigated swine manure feedstock. Batch semi-continuous experiments were carried out under mesophilic conditions. reactor with recovery, to...

Bacteroides amylophilus strain H I 8 produced protease(s), active at pH 7.0, when grown anaerobically in a simple maltose, ammonium sulphate, cysteine, sodium bicarbonate and salts medium. Protease production was neither induced nor repressed by a wide range of nutrients. Protease was synthesized by exponentially growing organisms and 20% of it was liberated into the growth medium. The cell-bou...

Three phase partitioning, a technique described for protein purification, has been employed for precipitation and purification of three different commercial preparations of alginates. Three phase partitioning works by the addition of /-butanol to aqueous solution of the polymer containing 20-30% ammonium sulphate (w/v). Three phases formed are: upper /-butanol layer, interfacial polymer precipi...

The inhibitors may potentially be used for multiple therapeutic application in viral, bacterial, fungal disease and physiological disorder. In traditional Indian medicine system cassia tora is reportedly effective in treatment of skin and gastrointestinal disorder. The present work describe the isolation extraction purification characterization of trypsin inhibitor from cassia tora seeds. Purif...

Background: The compositions of Ferrous sulphate, Agarose and Xylenol orange dye (FAX) and Ferrous sulphate, Gelatin and Xylenol orange dye (FGX) in solution of distilled water and sulphuric acid are two tissue-equivalent gel dosimeters. Ionizing radiation causes oxidation of Fe2+ ion to Fe3+ ions which diffuse through the gel matrix and blur the image of absorbed dose over a period of hours af...

  All desalination methods which are currently used have limitations. A newly designed instrument by Zare A.M. was tested and compared with currently used method in Razi Vaccine and Serum Research Institute(RVSRI). Samples of anti snake venom for desalination was provided by department of anti-serum, RVSRI. Parameters included in this study were time and water consumption during desalination pr...
