Abstract

The main purpose of polymer injection is to reduce the water-oil mobility ratio. Polymers that are widely used are polyacrylamide and polysaccaharides. By increasing the viscosity of the injection fluid, polymer injection can increase the sweep efficiency thereby increasing oil recovery. Refining on petroleum is highly dependent on the efficiency of macroscopic and microscopic pressing. This research purpose is to determine whether the viscosity effect resulted from mesona palustris addition on chitosan polymers could make a good viscosity for oil recovery. The method used in this research is a laboratory experiment with an Ostwald viscometer. The salinity of the formation water used in this study was 20.000 ppm with variations in polymer concentrations of 500 ppm, 1.000 ppm, and 2.000 ppm on the polymer without a mixture of mesona palustris and with a mixture of mesona palustris. The results showed that there was a decrease in polymer viscosity with the addition of mesona palustris to the chitosan polymer, namely the polymer concentration of 500 ppm decreased from 1,56 cp to 1,04 cp, the polymer concentration of 1.000 ppm decreased from 1.87 cp to 1.21 cp. And at a polymer concentration of 2.000 ppm it decreased from 2.38 cp to 1.43 cp.

Abstract

Groundwater is a vital water source for many communities, especially in rural areas, but its quality often fails to meet clean water standards due to contaminants such as heavy metals, organic compounds, and unsuitable pH, TDS, and EC levels. This study examines an integrated water treatment system combining adsorption and ultrafiltration technologies. The process begins with adsorption using zeolite and coral ginger stone to remove contaminants through ion exchange and Van der Waals interactions. The pre-treated water is then filtered through an ultrafiltration membrane to eliminate suspended solids and microorganisms based on pore size exclusion. The novelty of this study lies in the variation of adsorbent compositions, namely 100 g zeolite, 100 g coral ginger stone, and a 50:50 g mixture. Results indicate that the 50:50 combination provides the highest efficiency in improving groundwater quality. Under optimal conditions, TDS decreased to 38 ppm, EC to 76 µS/cm, temperature reached 29.8 °C, and pH approached neutral at 6.28, meeting clean water standards.
