Use of Coconut Shell As An Alternative Media of Water Filtration Replacement for Formation

Abstract

The quality of the injection water is a matter of concern in the injecting of a water formation (injection water). In an effort to improve the quality of water injection usually treatment in the form of filtration first. The water formation that has passed the wash tank is not completely free from crude oil, so it is necessary to filter before injection. Generally, charcoal and other types of activated carbon are commonly used as cartridge filters for the separation of manufactured water from crude oil, usually less efficient due to the long time and relatively high cost. The research using coconut shell is expected as an alternative to the use of water formation filtration cartridge (charcoal and other activated carbon), the research is done by preparing the waste of coconut shell with sample size in the form of sample 1 (Fine with mess 40), sample 2 (Medium with mess 30), sample 3 (Coarse with mess 20), sample 4 (Fine-Medium), sample 5 (Fine-Coarse) and Sample 6 (Medium-Coarse). Then tested filtration with water produced that still contain oil content. The samples analyzed were water formation samples before and after filtration using filtration water formation media with coconut shell cartridge of each size, samples analyzed with speed of flow rate, sediment and oil content before and after filtration test. The best result will show the fastest flow rate, the lowest percentage of sediment and the biggest decrease of oil content, then the filtration media is obtained from the scorring result with the best affair of sample number 6, number 4, number 5, number 1. number 3 and number 2
