4.1 Introduction

From the survey conducted at Desa Kim Loong Palm Oil ( DKLPO ) at Keningau, the research worker had gathered a full observation of full works operations. The factory had channeled the H2O from the river as their primary H2O beginning to the reserved pool before they feeds the H2O needed to the sand filter utilizing the pump. Furthermore, the H2O will be channeled into the overhead armored combat vehicle after the H2O gone through a filtering procedure in the sand filter. This procedure is done to do certain the H2O taken from the river is unsoiled from unnecessary wastewaters and ready to be used in plantation operations.

As the H2O was pumped into the overhead armored combat vehicle after filtrating procedure, the research worker started the procedure of finding the entire H2O used at the factory. In carry oning the confirmation procedure, the research worker had calculated manually about the H2O use as the research worker considered to settle on happening the information determined for each equipment involved in the factory operation such as the H2O used by the boiler. Furthermore, the manual computation has to be done as there are no well-functioned flow metres in the factory. In add-on, the manual computation that has been conducted by the research worker is utilizing the simple equations such as the overhead armored combat vehicle been measured its perimeter by mensurating tape.

Then, the research worker had closed the H2O provender pipe for five proceedingss in order to acquire the volume of the H2O used by supervising the H2O used utilizing the index from outside the armored combat vehicle. On the other manus, as for boiler, the research worker had to shut the pipe signifier overhead armored combat vehicle and hot H2O armored combat vehicle before the research worker marked the initial degree of the degree index where the index was traveling freely up to five proceedingss before the last place on the index degree marked. However, the research worker already measured the overhead armored combat vehicle ‘s perimeter before the country of the overhead armored combat vehicle calculated to find the volume H2O used for the boiler.

Furthermore, to corroborate the dependability of the survey, the research worker was determined to measure the factory operations for four hebdomads period. Therefore, the research worker had asked the employee at the factory to help the research worker in roll uping the information for needful period. Graciously, with the assistance by the factory ‘s employee, the research worker is able to finish the tabular array of H2O recess to chilling pool and H2O mercantile establishment from discharge pool informations. The information taken is from 10th October 2009 boulder clay 08th November 2009.

Figure 4.1 shows the mass balance for H2O footmark in Desa Kim Loong Palm Oil ( DKLPO ) . Based from the figure, the research worker had indentified the H2O beginning for the H2O used for the palm oil operations which is the river where the H2O from the river was taken to the pool before the H2O was chanelled to the operating expense armored combat vehicle after the filtering procedure.

The figure 4.1 besides tells us 135.87 m3/h of H2O use at the Overhead Tank. Hence, the H2O was supplied to Domestic, Hot Water Tank and Softener. The H2O use at Domestic is 13.59 m3/h, 79.82 m3/h at the Hot Water Tank while 42.46 m3/h of H2O used by the Softener. The H2O use at the Softener besides includes the use at Buffer Tank, Dearator and Boiler.

In add-on, the Press had used 23.95 m3/h of the H2O supply while the H2O use by the Oil Room is 55.87 m3/h. The H2O used by the Oil Room besides included the H2O used by Separator No. 1, Separator No. 2, Separator No. 3, Separator No. 4, Separator No. 5 and the Kernel Plant. While for the H2O use by the Press besides includes Press No. 1, Press No. 2, Press No. 3, Press No. 4, Press No. 5, Press No. 6 and the Oil Gutter.

The computation for each constituent for this operation is done manually by the research worker utilizing the simple equations. Furthermore, the mass balance for H2O footmark appraisal in the factory is really indispensable to this survey as the research worker determined the H2O use by each equipment used in the factory operations utilizing the mass balance.

Table 4.1 shows the informations taken for the waste recess to the chilling pool and the mercantile establishment from the discharge pool. In add-on, the information taken is for four hebdomads period where the information foremost taken on 10th October 2009 while the concluding information taken is on 08th November 2009. For the information completion, the research worker merely able to manually cipher the informations for two times while the remainder of the information was taken by the assistance of the employee of Desa Kim Loong Palm Oil ( DKLPO ) .

Furthermore, the tabular array non merely shows the information of waste recess to the chilling pool and the information of the mercantile establishment from the discharge pool, but besides shows the differences between the concluding and initial recess and the differences between the concluding and initial mercantile establishment. Furthermore, Table 4.1 besides illustrates the differences between the differences of the recess and the differences of the mercantile establishment. Therefore, the monthly sum besides has been shown in Table 4.1.

4.3 Discussion on Data Interpretation

Form the information collected, the research worker has successfully answered the first research inquiry ; does the H2O footmark can find the entire usage of H2O supply in each of the equipment. As the informations shown in Figure 4.1, the research worker had confirmed that the H2O footmark appraisal can find the entire usage of the H2O supply in each equipment used in the factory operations at Desa Kim Loong Palm Oil ( DKLPO ) .

Through H2O footmark appraisal, the research worker identified that the Overhead Tank had used 135.87 m3/h of H2O use during the factory operations. 13.59 m3/h of H2O supply besides has been used at the Hot Water Tank while while 42.46 m3/h of H2O used by the Softener. On the other manus, the H2O use at Domestic is 13.59 m3/h. Furthermore, the appraisal besides identified that 23.95 m3/h of H2O supply is used by the Press while the Oil Room used 55.87 m3/h. Therefore, the research worker managed to make the confirmation on the H2O use on each equipment involved in the DKLPO factory operations.

From Table 4.1, the research worker had indicated that the sum of untreated wastewaters in is 1139 m3/day while the sum of treated wastewaters out is 2611m3/day. There are some possibilities of this affair such as the add-on of the groundwater at the intervention works, the rain bead and the effects of the differences between 20 hours treating hr per twenty-four hours and 24 hours intervention hr per twenty-four hours. The immense difference of untreated wastewaters in and treated wastewaters out is likely because of the groundwater add-on at the intervention works which the intervention works normally had some sum of old treated H2O in the pool. Therefore, the new H2O use has been added with the groundwater and makes a immense add-on on end product of H2O wastewaters.

In add-on, the rain bead besides might be another cause for the difference between untreated wastewaters in and treated wastewaters out. This is because, the pools used at the intervention works are unfastened pool which this might be one of the factors of the immense incensement in the treated wastewaters out compared to the sum untreated wastewaters in. The treated wastewaters out perchance added with the rain bead which made the treated wastewaters out unequal with the untreated wastewaters in.

On the other manus, the differences between 20 hours treating procedure per twenty-four hours and 24 hours intervention procedure per twenty-four hours might are related to the differences between entire untreated wastewaters in and entire treated wastewaters. Therefore, the research worker had indicated that there is 4 hours add-on to the intervention procedure compared to 20 hours treating procedure in the factory operations. The add-on of 4 hours intervention procedure had increased the sum treated wastewaters out as the operation continues for 4 hours after the processing procedure finished. Hence, the intervention still processes the balance of H2O in the intervention ponds as the pools normally had groundwater in it which the pools are biological intervention pools.

Therefore, these discussed three factors might be a factor for the differences between entire untreated wastewaters in and entire treated wastewaters out where the factors mentioned had close dealingss to the volume of the effluent in the pools.

Figure 4.2: Pie Chart of Water Utilization for DKLPO

The pie chart above shows the per centum of the H2O use by the equipments used in palm oil operation at Desa Kim Loong Palm Oil ( DKLPO ) . The pie chart shows that the most user of the H2O supply is the Hot Water Tank where it used 58.75 per centum of the H2O supply form the Overhead Tank. The 2nd user which is the most of import equipment in the factory operation is the Boiler where the Boiler imposingly merely used 31.25 per centum of the entire H2O supply from the Overhead Tank.

In add-on, this really find had answered the research inquiry which the research worker had questioned in the Chapter 1 if the Boiler is the chief user of the H2O supplied. Therefore, from the pie chart above, the boiler is non the chief user of the H2O supply where the Boiler merely managed to utilize 31.25 per centum from the entire H2O supply. Hence, this survey had confirmed that the chief user of the H2O supply is the Hot Water Tank where it channeled 17.63 per centum of the H2O to the Press while another 41.12 per centum is channeled to the Oil Room. Furthermore, the other 10 per centum of H2O supply is used at the Domestic equipment.

Hence, DKLPO mill needs an efficient H2O appraisal as the Boiler should be a chief user in the factory operations while on the other manus, the chief user of the H2O supply in DKLPO operations is the Hot Water Tank.

4.4 Decision

In decision, from the informations collected and interpreted, the research worker had identified the entire usage of H2O supply in each equipment involved in the factory operations by making the H2O footmark appraisal. From the interpreted information, the research worker had made some recommendations for effluent minimisation as the H2O discharged from the factory operations is used merely to fertilise the estate plantation. Therefore, the factory keeps utilizing the H2O supply from river without reuse the effluent in the factory operations which the H2O used recklessly.

As the recommendations of the solutions had been made by the research worker in the following chapter, the expected fresh H2O ingestion by 30 per centum and 15 per centum effluent decrease in this instance survey. Therefore, the increasing H2O reuse by palm oil factory would lend to sustainable H2O direction and minimizes the use of fresh H2O.
