Trimethylene glycol dimethyl ether (triglyme), a Polyethylene glycol (PEG)-like hydrophilic polymer, was deposited by plasma polymerization to reduce RO membrane’s organic fouling tendency. This method has the great advantage of achieving modification in one single step. A series of plasma deposition experiments were undertaken. The successful coating of the polymer was confirmed by X-ray photo...

Membrane fouling is a major drawback of reverse osmosis (RO) membrane filtration as it negatively affects the quantity and quality of the permeate and lifespan of the membrane. Spacer plays a pivotal role in hydrodynamics of the membrane channel thus influencing the membrane fouling. In this study, a series of novel sinusoidal spacers that can form unobstructed sinusoidal membrane channels were...

In this study we investigate the formation of protein-resistant polymer surfaces, such as aliphatic polyesters, through the deposition of self-assemblies of amphiphilic poly(l-lactide)-b-poly(ethylene oxide), PLLA-b-PEO, copolymers as stable nanoparticles with a kinetically frozen PLLA core on model PLLA surfaces. The length of the PEO chains in the corona was tuned to achieve polymer brushes c...

The recent Diplomatic Conference held (1-5 October 2001) by the International Maritime Organization (IMO) in London adopted the Draft Convention prepared by The Marine Environmental Protection Committee (MEPC) of IMO for the "Control of Harmful Anti-fouling Systems for Ships." The convention has been developed to immediately ban the use of Tributyltin (TBT) globally in anti-fouling paints to "p...

The use of the advanced membrane separation plants for water treatment and wastewater allows achieving high quality treatment. However, in process operation units, additional problems associated with fouling such as formation a layer sludge on surface arise. In this paper authors tried to consider methods non-reagent control plants, particular anti-adhesion coatings nanomaterials. recent years,...

Magnetic artificial cilia (MAC) are small actuators inspired by biological found in nature. In microfluidic chips, MAC can generate flow and remove microparticles, with applications anti-fouling. However, the used for anti-fouling current literature has dimensions of several hundred micrometers length, which limits application to relatively large length scales. Here, biologically-sized magnetic...

The development of effective mitigation techniques against Botryllus schlosseri and Botrylloides violaceus colonizing blue mussel aquaculture operations has not been well studied. The objectives of our research were to determine the efficacy of using pressurized seawater in the mitigation of colonial tunicate fouling and to identify optimal treatment timing and frequencies in reducing tunicate ...

Inorganic fouling is one of the critical operational issues in reverse osmosis membrane. Few researches investigated effects of membrane surface characteristics on inorganic fouling and on anti-scaling techniques although the fouling occurs on the membrane surface. The objective of this paper was to examine whether different characteristics of deposition of calcium carbonate solids would occur ...
