Forward and Reverse Osmosis Process for Recovery and Re-use of Water from Polluted Water by Phenol
...Show More Authors

The research aims to apply the novel forward osmosis (FO) process to recover pure water
from contaminated water. Phenol was used as organic substance in the feed solution, while sodium
chloride salt was used as draw solution. Membranes used in the FO process is the cellulose
triacetate (CTA) and polyamide (thin film composite (TFC)) membrane. Reverse osmosis process
was used to treatment the draw solution, the exterior from the forward osmosis process. In the FO
process the active layer of the membrane faces the feed solution and the porous support layer faces
the draw solution and this will show the effect of dilutive internal concentration polarization and
concentrative external concentration polarization.
In the FO process was a run-time for five hours, and the concentration of phenol 100 and
1000 mg/l, and for the NaCl the concentration was 10000 and 30000 mg/l. It was found that
recovery percent increases with increasing time, while water flux through membrane decreases with
increasing time. Also, it was found that recovery and water flux increases with increasing draw
solution concentration, on the contrary, water flux and the percentage of recovery decreases with
increasing the concentration of phenol (feed solution). Increase in draw solute (NaCl) concentration
has more effect on the water flux in FO process compared with increase in the concentration of
phenol. Outlet phenol concentration increases with time, while the outlet salt concentration
decreases with increasing the time. The results showed that the cellulose triacetate membrane gave
the highest recovery ratio from the thin film composite membrane. The highest recovery was
reached in five hours is 51.33%, while using CTA membrane recovery rate increase, by 23%
compared with TFC membrane. The value of the resistance to solute diffusion within the membrane
porous support layer is 36.83 h/m. Reverse osmosis is perfect method for removal of dissolved salts
from water, thus its suitable process for reducing the content of NaCl in draw solution; therefore the
sodium chloride rejection percentage was 91.6 – 96 % for polyamide membrane (TFC). Within two
hours of work of the reverse osmosis system the recovery percentage of pure water is 58%.

An Image Processing Algorithm to Address the Problem of Stains Merge on Water Sensitive Papers and Its Impact on the Evaluation of Spray Quality Indicators
...Show More Authors

There are many techniques that can be used to estimate the spray quality traits such as the spray coverage, droplet density, droplet count, and droplet diameter. One of the most common techniques is to use water sensitive papers (WSP) as a spray collector on field conditions and analyzing them using several software. However, possible merger of some droplets could occur after they deposit on WSP, and this could affect the accuracy of the results. In this research, image processing technique was used for better estimation of the spray traits, and to overcome the problem of droplet merger. The droplets were classified as non-merged and merged droplets based on their roundness, then the merged droplets were separated based on the average non-m

The Effect of White Rot Fungus (Ganoderma sp) as Decomposers on Composting Using Combination of Cattle Feces and Water Hyacinth (Eichhornia crassipes) as Organic Matter
...Show More Authors

In Indonesia, cattle feces (CF) and water hyacinth (WH) plants are abundant but have not been widely revealed. The use of microorganisms as decomposers in the fermentation process has not been widely applied, so researchers are interested in studying further. This study was to evaluate the effect of the combination of CF with WH on composting by applying white-rot fungal (WRF) (Ganoderma sp) microorganism as a decomposer. A number of six types of treatment compared to R1(ratio of CF:WH)(25%:75%)+WRF; R2(ratio of CF:WH)(50%:50%)+WRF; R3(ratio of CF:WH)(75%:25%)+WRF; R4(ratio of CF:WH)(25%:75%) without WRF; R5(ratio of CF:WH)(50%:50%) without WRF; R6(ratio of CF:WH)

Optimizing Gas Lift for Improved Oil Recovery in a Middle East Field: A Genetic Algorithm Approach
...Show More Authors

This paper presents a study of the application of gas lift (GL) to improve oil production in a Middle East field. The field has been experiencing a rapid decline in production due to a drop in reservoir pressure. GL is a widely used artificial lift technique that can be used to increase oil production by reducing the hydrostatic pressure in the wellbore. The study used a full field model to simulate the effects of GL on production. The model was run under different production scenarios, including different water cut and reservoir pressure values. The results showed that GL can significantly increase oil production under all scenarios. The study also found that most wells in the field will soon be closed due to high water cuts. Howev
