WebThere are also certain membrane-based systems that actually counter act fouling and scaling. Closed-Circuit based RO (CCRO) prevents fouling because the CCRO process provides a constantly changing membrane environment. The plug flow sequence found in the CCRO process also helps to purge the membranes of foulants several times per hour. WebFouling was retarded with only a low fibre concentration and reduced further as fibre concentration was increased. 机译： ...

WebBiological fouling (or biofouling) is a significant problem on wet surfaces such as ships, boats, electric cables, and buoys caused by the growth of microorganisms, plants, and … Biofouling or biological fouling is the accumulation of microorganisms, plants, algae, or small animals where it is not wanted on surfaces such as ship and submarine hulls, devices such as water inlets, pipework, grates, ponds, and rivers that cause degradation to the primary purpose of that item. … See more Biofouling organisms are highly diverse, and extend far beyond the attachment of barnacles and seaweeds. According to some estimates, over 1,700 species comprising over 4,000 organisms are responsible for … See more Shipping companies have historically relied on scheduled biofouler removal to keep such accretions to a manageable level. However, the … See more Biofouling, especially of ships, has been a problem for as long as humans have been sailing the oceans. The earliest written mention of fouling was by Plutarch who recorded this explanation of its impact on ship speed: "when weeds, ooze, and filth stick upon its sides, … See more • Kirschner, Chelsea M; Brennan, Anthony B (2012), "Bio-Inspired Antifouling Strategies", Annual Review of Materials Research, 42: 211–229, Bibcode:2012AnRMS..42..211K, doi:10.1146/annurev-matsci-070511-155012 See more Governments and industry spend more than US$5.7 billion annually to prevent and control marine biofouling. Biofouling occurs everywhere but is most significant economically to the shipping industries, since fouling on a ship's hull significantly increases See more Antifouling Antifouling is the process of preventing accumulations from forming.

Accumulation of biological fouling. On a heat transfer surface the growth of biological materials results in biofouling. In this case biological micro and macro organisms are stick to the heat transfer surface. When microorganisms (e.g., algae, bacteria, molds etc.) and their products grow they form microbial fouling.
