Fouling of electrodialysis membranes by organic substances

Desalination, 2000
In this investigation, the influence of various kinds of organic solutes on the fouling of an anion and a cation selective ED membrane was studied. Fouling by adsorption of organic matter onto the membrane was measured as an increase in the membrane resistance with time.

Ecology of Fouling Organisms in a Polluted Area

Nature, 1970
LITTLE is known about the growth and development of fouling organisms in polluted areas. At times, large numbers of oysters and cockles have been killed by crude or fuel oil in certain beds along the French and English coasts1. On the other hand, it has been demonstrated2 that oysters are very tolerant of crude oil overlayering the water, emulsified in

Tissue sloughing in the sponge Halichondria panicea: a fouling organism prevents being fouled

Oecologia, 1989
Specimens of the sponge Halichondria panicea Pallas kept in running sea-water aquaria at 15° C slough off their complete outer tissue layer in regular intervals of three weeks. Sloughing starts at the rim of the oscula and extends over the whole surface within two weeks. Microscopic inspection of the tissue flakes shows them to harbour large numbers of

THE ROLE OF SLIME FILM IN THE ATTACHMENT OF FOULING ORGANISMS

The Biological Bulletin, 1948
The attachment of larvae of fouling organisms to submerged surfaces is influenced, in varying degree, by many factors. Among these, are several dependent upon particular properties of surfaces including the tendency to acquire slime or primary films when exposed in sea water.

Organic fouling and floc transport in capillaries

Separation and Purification Technology, 2011
Abstract Coagulation and adsorption are two widely recommended pretreatments to ultrafiltration (UF) membranes. Optimal concentrations of ferric chloride and powdered activated carbon (PAC) are reducing membrane fouling and increasing the retention of the organic matter.

Ecology of marine fouling organisms at Eastern Johore Strait

Environmental Monitoring and Assessment, 1991
Marine biofouling causes problems to marine structure and obstructs condenser tubes in cooling systems which use sea water as the coolant. The main purpose of this study is to investigate the seasonal ecology of biofouling organisms such as the green mussel, Perna viridis, the dominant fouling species in the Eastern Johore Straits at the Senoko Power ...

Chemical reaction fouling of organic fluids

Chemical Engineering & Technology, 1992
AbstractChemical reaction fouling of heat exchangers involves deposition that is caused by chemical reactions which occur in the fluid, or on the surface itself. The factors which influence fouling of organic fluids via autoxidation and thermal decomposition processes are described and the dependence of the rate of thermal fouling on chemical effects ...
