in this paper, the effect of transmembarne pressure (tmp) at levels of 1, 1.75 & 2.5 bar, process temperature (t) at levels of 30 & 60oc and operation time (t) at levels of 15, 30, 45 & 60 minute on the permeate flux, sugar rejection, non-sugar rejection and fouling as membrane performance indexes investigated. membrane system used in this research was ceramic tubular module and it had effectiv...
Non-thermal processing methods, such as pulsed electric field (PEF) and tangential-flow microfiltration (TFMF), are emerging processing technologies that can minimize the deleterious effects of high temperature short time (HTST) pasteurization on quality attributes of skim milk. The present study investigates the impact of PEF and TFMF, alone or in combination, on color and volatile compounds i...
Coagulation, magnetic ion exchange resin (MIEX) and biological activated carbon (BAC) were examined at lab scale as standalone, and sequential pre-treatments for controlling the organic fouling of a microfiltration membrane by biologically treated secondary effluent (BTSE) using a multi-cycle approach. MIEX gave slightly greater enhancement in flux than coagulation due to greater removal of hig...
Metastatic disease is the most important factor in determining the survival of sarcoma patients. Since sarcoma metastasis is predominantly hematogenous, we hypothesized that detection and quantification of circulating tumor cells (CTCs) could reflect response to therapy and risk of metastatic relapse. We evaluated the presence of CTCs using a novel animal model and in the blood of patients with...
Removal of residual organic matter, phosphates and ammonium from thermofilically digested pig manure
Full-scale anaerobic digestion of pig manure often resulted in liquid effluents with considerably high organic matter, ammonia and phosphates content. If not enough agricultural land is available, the disposal of this effluent requires additional treatment. Different process scheme for reduction of the organic matter and nutrients from thermofilically digested pig manure were tested in full-sca...
Polymer-based membranes have advanced or novel functions in the various membrane separation processes for liquid and gaseous mixtures, such as gas separation, pervaporation (PV), reverse osmosis (RO), nanofiltration (NF), ultrafiltration (UF), microfiltration (MF), other critical applications of water purification, solvent concentration, recovery [...]
