Electroding Methods for in situ Reverse Osmosis Sensors
… in an in situ sensor able to detect RO membrane protein fouling. Four electroding techniques were explored: i) gold exchange-reduction, ii) encapsulated carbon grease, iii) "direct assembly process" (DAP), and iv) platinized polymer graft. The novel platinized polymer graft method involves …

Interaction between membrane and protein properties on flux decline during sterile microfiltration
… further the understanding of flux decline due to protein fouling. Many times the operating conditions, the type of membrane and type of protein all interact to have an effect on protein fouling and flux decline. Normal-flow microfiltration experiments were conducted using uncoated …

A study on organic fouling of reverse osmosis membrane
… (BSA), which were model polysaccharide and protein, respectively, to study the polysaccharide and protein fouling behavior in two lab-scale reverse osmosis (RO) membrane cells in different dimensions. The first test cell was 0.1 m in length and was treated as a homogenous system while the …

Electrospinning polyampholyte nanofiber membranes
… REQUEST.] The elimination of nonspecific protein adsorption is an important challenge in many biomaterial applications. To address this issue, numerous nonfouling chemistries have been investigated. [2-(acryloyloxy) ethyl] trimethyl ammonium chloride (TMA) and 2-carboxy ethylacrylate (CAA) …

Characterisation of feed and membrane properties for industrial ultrafiltration management
… impact of feed and membrane characteristics on fouling behaviour in complex feed scenarios. However, this assessment is limited by current understanding of (a) the utility of common foulant characterisation tools for the detection of organic fouling propensity, and (b) the impact of membrane …

Vertically-aligned carbon nanotube membranes for water desalination and ultrafiltration
… and high performance, they are susceptible to fouling. Such drawbacks encourage the invention of new type of membranes. There are many research groups who are working on different membrane materials, surface modification or incorporation of nanoparticles in existing membranes. Types of …

Fouling mechanisms in the membrane filtration of single and binary protein solutions
In this study the fouling mechanisms of various microfiltration and ultrafiltration membranes were studied when subjected to crossflow filtration using various protein solutions. Experimentation was carried out using controlled flux experiments and fouling phenomena was investigated via the …

Mitigating fouling of heat exchangers with fluoropolymer coatings
Fouling is a chronic problem in many heat transfer systems and results in the need for frequent heat exchanger (HEX) cleaning. In the dairy industry, the associated operating cost and environmental impact are substantial. Antifouling coatings are one mitigation option. In this work, the fouling …
