First set to operation Before putting into operation for the first time check that: All connecting pipes and flanges specially on the suction side, are completely tight

6.6 Coalescing bed-type oily water separators The coalesce is capable of forming oil globules up to l2 mm diameter and the heavier fuel oils usually form long 'stalagmites' which grow to a considerable size before they are released. Because of the 1ow velocities employed the collected oil can flow past the water screen without becoming re-entrained and carried through into the outlet

General Operating Procedure Before pumping oily water into the separator it is important that the separator is completely filled with clean water, either direct from the sea or through the filling valve provided for this purpose. It is essential to keep the lower internal surfaces and outer chamber from becoming coated with oil

4.1 Function The purpose of the operation is either to liberate a liquid from strange particles, or to separate two intermixed liquids

The principle of separation by which all commercially available oil/Water separators is the gravity differential between oil and water. In oily water mixtures, the oil exists as a collection of almost spherical globules of various sizes. The force acting on such a globule causing it to move in the water is proportional to the difference in weight between the oil particle and a particle of water of equal volume. This can be expressed as:

Cleaning, overhaul, lubrication. Satisfactory functioning cannot be ensured unless the parts in contact with liquid are carefully cleaned before assembly. This applies particularly to seal rings, sliding surfaces, guiding and contact surfaces, and threads. Also take care that no burrs are knocked up on the metal parts when handling them. Follow the directions given in chapter 5.4 and 4.5

3.4 ALFA-LAVAL Separator MAPX 207S-20 general information 3.4.1 MAPX information Contents – Correct installation, suitable treatment of the liquid before and after the passage through the machine, – correct operation and handling of the machine according to the directions given in instruction book, – cleanliness, carefulness and methodical overhaul are factors of the greatest importance for ensuring the best machine function and intended results

3.2 Treatment of detergent type lubricating oils The main function of detergent lubricating oil is to keep solid contaminations in suspension and prevent both their agglomeration and deposition in the engine. This function reduces ring sticking, wears of piston rings and cylinder liners, and generally improves the cleanliness of the engine. agglomeration
