A problem in water systems in which dust, dirt, clay, and dissolved minerals contaminate the makeup water and form deposits that can clog components.
Compounds that adhere to the membrane surface creating a porous, yet permeate limiting flow control layer (gel layer). Some examples are bacteria, oil & greases, suspended solids, "organic compounds" like polymers or coagulants.
Occurs when large numbers of plants or animals attach and grow on various structures (floats, pipes, and pilings), often interfering with their use. Fouling organisms include barnacles, mussels, bryozoans, and sponges.
Contamination of feeding or respiratory areas of an organism by excrement, sediment, or other matter. Also, accumulation of sessile marine organisms on the hull of a boat or ship so as to impede its progress through the water.
Certain deposits which accumulate on the inside of the gun after a specific amount of time. If the gun is not cleaned regularly, this can negatively affect the accuracy of your rifle.
Contamination or biological growth on the reverse osmosis membranes or pretreatment filters.
Deposition of solid material in the element from the feed stream of the membrane.
Accumulation of foreign matter, such as mud or debris, in a cooler, pipe, or valve. In a cooler, H2O P and T will be seen to increase, as well as CTD. ( 200)
An accumulation of deposits. This term includes accumulation and growth of marine organisms on a submerged metal surface and also includes the accumulation of deposits (usually inorganic) on heat exchanger tubing.
In crossflow filtration, the reduction of flux that is attributed to a buildup of solids on the surface of the membrane.
The clogging of membrane filters due to the buildup of particles on the membrane and in the membrane pores.
Marine growth such as weeds or barnacles adhering to the surface.
1) a gelatinous, slimy accumulation on the waterways of a conduit, resulting from the activity of organisms in the waters. Fouling is more easily removable than tuberculation. 2) Fouling may be found on concrete, masonary, and metal surfaces, but tuberculation is found only on metal surfaces. b c
An accumulation of marine organism deposits on a submerged metal surface. Fouling also refers to the accumulation of normally inorganic deposits on heat exchanger tubing.
Marine growth such as weeds or barnacles adhering to submerged surfaces.
The process in which undesirable foreign matter accumulates in a bed of filter media or ion exchanger, clogging pores and coating surfaces and thus inhibiting or retarding the proper operation of the bed.
The deposits that build up in the barrel of a gun after it is fired. Fouling can either be soft and harmless carbon residue, or more persistent lead or copper, both of which are detrimental to accuracy.
An assemblage of organisms growing on the surface of floating or submerged man-made objects (such as pilings or boat-bottoms) that increases resistance to water flow or otherwise interferes with the desired operation of the structure.
In electrodialysis applications, the deposit of organic or other materials on the surface of the electrodialysis membrane surface, causing membrane inefficiencies.
The accumulation of refuse in gas passages or on heat absorbing surfaces which results in undesirable restrictions to the flow of gas or heat.
