Dose recommendations have to be made on a case-by-case basis. The dosage rate varies and depends on nature copoaition of phase materials and it may varies from 5 to 10 ppm, so we suggest adding the lower levels to your laboratory bench tests to verify the correct dosage for the specific application. Finding the most cost-effective dosage, as well as determining the best conditions of temperature, slow mixing, settling time, etc., is best done in the laboratory, using a sample of the actual oil or waste and a sample of Demulsifier.


Typical method for Evalution of Demulsifier :

Step 1 :Treat 100ml of the emulsion with 40 mg/litre of Demulsifer, (using 1% w/v solution in xylene in 100 ml graduatd conical tube) and give 100 shakes of approximately 12 in stroke

Step 2 : Place treated emulsion in water bath maintained at 70 +1^oC for a period of 15 minutes and allow it to settle for 5 minutes at 30+2^oC. measure the quantity of clear water settled

Step 3 : Conduct a blank test with untrented emulsion under condition similar to treated emulsion

Step 4 : Substract the water seprator if any in blank test from treated sample and denote it as V. Similarly subtract the water separated from blank from total water present in emulsion and denote it Vo.
