Rhamnolipids were evaluated as biofouling reducing agents in this study. The permeability of the bacterial outer membrane was increased by rhamnolipids while growth rate Pseudomonas aeruginosa not affected. surface hydrophobicity through release lipopolysaccharides and extracellular polymeric substances from cell membrane. for prevention cleaning biofilms. A high degree biofilm detachment observed when used a agent. In addition, effective reduction occurred applied to various species...
ABSTRACT Biofouling is a major problem in membrane-based water treatment systems because it causes flux decline and necessitates an increase cleaning frequency. The objective of this study was to evaluate the effectiveness enzyme method on reduction extracellular polymeric substances (EPS). For test, acylase I used as cleaves quorum sensing signal molecules proteinase K degrading proteins. It found that 5 μg/mL I, 100 K, combination both enzymes (5 K) could remove 9.0, 56.6, 33.7% bacteria...
The change in bacterial community structure induced by competition and succession was investigated during seawater reverse osmosis (SWRO) order to elucidate a possible link between the consortium on SWRO membranes biofouling. To date, there has been no definitive characterization of microbial diversity terms distinguishing time-dependent changes richness or abundance species. For within biofilms membrane surface, using cross-flow filtration test unit operated for 5 100h, respectively. As...
Reverse osmosis (RO) membranes are widely used for desalination plant. However, membrane biofouling cause decreasing performance. This work focused on finding optimum cleaning conditions in RO processes. The effect of such as agent concentration, temperature and time efficiency were investigated Centers Disease Control (CDC) annular biofilm reactor. Alkaline agent, sodium hydroxide (NaOH) which is well known removing organic foulant membrane, was used. Total bacteria number measured with...
ABSTRACT Aquaporin biomimetic membrane can only transfer water molecules in and out of the while preventing passage other smaller ions solutes. AquaporinZ (AqpZ), widely spread Escherichia coli cell membrane, has shown higher permeability than conventional membranes. Application those exceptional properties as purification material is promising. The objective this study was to assess protein expression conditions for AqpZ mass production. Recombinant successfully synthesized identified via...
Abstract BACKGROUND An ultrafiltration microbial fuel cell ( UF‐MFC ) is a novel technology that can simultaneously produce high‐quality effluent and electricity during wastewater treatment. To increase the power density mitigate inevitable biofouling phenomena in UF‐MFCs , anode direct contact ADC method was tested. application improves densities by reducing distance between electrode UF membrane (lowering internal resistance), mitigates on surface due to of porous with surface. RESULTS The...
In a wastewater reclamation and reuse system, even though reverse osmosis (RO) or forward (FO) membrane is utilized as main process, micropollutants, especially non-biodegradable matters, such pharmaceuticals, endocrine disrupting compounds, cancer causing can give menaces to natural water environment human. Initially, in this study, pharmaceuticals were measured present both effluent brackish investigate how much the remain after naturally degraded stream. Through filtration with RO FO,...
Quantum dot (QD)-based biomolecule hybrids have recently attracted much attention in specifically identifying and labeling target proteins. In this study, QD encapsulated with immunoglobulin antibodies, as a building block biosensors, was investigated to clarify the most efficient configuration photoluminescence behavior. Both biological recognition capacity emitting signal of antibody-coupled nanocrystal were validated through photoelectrical characterization procedure. Derivation optimum...
Biofilm formation in membrane processes causes a flux decline, pressure drop increase, and other adverse effects. Understanding the mechanisms of fouling, control, cleaning are important order to resolve fouling problems. In this paper, effect cell viability on biofouling was studied via feed water analysis autopsy. Pseudomonas aeruginosa PAO1 used as model bacteria. Biofouling tests were divided into two parts: live cells dead (autoclaved cells). The periodically collected every 3 h analyze...
