Does anyone know the types of fouling resistance and the ways to correct it?
Answer:
Fouling resistance is due to to accumulated deposits on the the flow surface usually in tubes such as heat exchangers where fouling can occur inside the tubes or outside the tubes as in cooling towers. Sedimentation occurs due to the hot surface which causes the extract of chemicals, like calcium carbonate, for instance and deposit them on the surface. There are other fouling agents such as the bio deposited in pipes or on membranes as in reverse osmosis water purification.
Normally preventive maintenance is the best way to combat fouling. Such as using copper amalgam pipes with at least 70% Copper. This type of pipes prevent bio fouling in the pipes. Other things used are sponge balls covered with abrasive material. Also small brushes are used in the flow stream.
To remove fouling one can use cleaning solutions, chemicals, mechanical action like scraping and brushing.
