This paper delineates sequential approach to explore integrated cost functions estimation forecast level biological by The capacity wise small range, medium range large groups plants with Bio-Reactor have been developed based on process design estimation. It has established through reg...

This study is to investigate on the long term performance of submerged membrane adsorption hybrid system (SMAHS) for organic matter removal from synthetic wastewater representative of biologically treated wastewater using low dose of powder activated carbon (PAC). A simple periodic backwash system is used to declog the hollow fiber membrane. In this reactor, bioreaction takes place due to the g...

Present study highlights on isolation of bioactive peptide from the sesame protein hydrolysate with an objective of better utilization sesame meal. Sesame protein isolate was enzymatically modified to prepare sesame protein hydrolysate using enzyme ‘Protease A Amano 2G’ in an enzyme membrane reactor and the hydrolysate was subsequently fractionated by ultrafiltration using membranes of decreasi...

Owing to the inherent shortcomings of conventional biological dye effluent treatment processes, researchers have proposed diverse intriguing approaches that await practical implementation. This study demonstrates the feasibility of an innovative membrane-coupled fungi reactor. Preliminary batch tests revealed the noteworthy role of biosorption along with biodegradation in decoloration, and also...

Living systems use fuel-driven supramolecular polymers such as actin to control important cell functions. Fuel molecules like ATP are used to control when and where such polymers should assemble and disassemble. The cell supplies fresh ATP to the cytosol and removes waste products to sustain steady states. Artificial fuel-driven polymers have been developed recently, but keeping them in sustain...

Benzene alkylation with propylene was studied in the gas phase using a catalytic membrane reactor and a fixed-bed reactor in the temperature range of 200-300 °C and with a weight hourly space velocity (WHSV) of 51 h-1. β-zeolite was prepared by hydrothermal synthesis using silica, aluminum metal and TEAOH as precursors. The membrane's XRD patterns showed good crystallinity for the β-zeolite fil...

The structures of biofilms deposited on the membrane surface under different dissolved oxygen (DO) conditions were characterized to identify its relation to membrane filterability in membrane bioreactors (MBR). The rate of membrane fouling for the low DO (LDO) reactor was 7.5 times faster than that for the high DO (HDO) reactor. Even though the biofilm deposited on the membrane surface in the H...

A device has been developed to increase and control the cell concentration in continuous culture fermentation reactors. This cell control device, used to study mixed culture methane fermentations, was developed because it is necessary to obtain cell concentrations much higher than can be obtained in a single stage reactor by adjustment of residence time or substrate concencentration. Designed a...

Enzymatic hydrolysis of lactose by -galactosidase (Lactozym) has been studied in a jacketed stirred-tank reactor (JSTR) and in a recirculation hollow-%bre bioreactor (RHFB). The hollow-%bre module was manufactured with modi%ed cellulose-acetate membrane (Cuprophan). The variables tested were: temperature (25–40◦C), lactose concentration (0.0278–0:208 M) and enzyme concentration (0.100–4:51 g l−...
