The aim of integrating lean manufacturing and parameter design is to minimize seven non-value wastes in addition to the traditional waste in clean water production. These additional wastes to be considered are overproduction, waiting, motion, transportation, inventory, overprocessing, and defects. Information obtained from each waste is the input for the parameter design of the mixing process. The result of interaction between these seven types of waste in the lean production of clean water reveals that overprocessing waste is the most influential input in the parameter design of the Taguchi method. In the process of adding the level of concentration of poly aluminium chloride coagulant in the mixing process, a turbidity level below 5 nephelometric turbidity units is obtained, which in fact is in accordance with the health standard for clean water. An observation was also made on the behavior of flocs as the effect of Brownian motion due to the attractive force of poly aluminium chloride coagulant and colloid particle. The particle was then examined using a scanning electron microscope to find out the dimension of grain-sized flocs as the result of sedimentation in the mixing process. By properly integrating lean manufacturing and parameter design to minimize waste, a quality water meeting the set standard would be produced.

This study aims to evaluate the influence of agitation conditions on the efficiency of the aggregation process when treating surface water containing humic substances. Laboratory tests were conducted by the jar tests using a variable speed paddle gang stirrer. Optimization of agitation intensity was determined by a Couette flocculator. Suspension was prepared using aluminium chloride as a destabilising reagent. Aggregation efficiency was evaluated by the determination of the degree of aggregation and by the test of aggregation. For all surface waters treated, the optimum treatability was demonstrated by applying higher velocity gradients (G=200–250 s−1). In addition to the laboratory tests, the plant measurements with water containing increased amounts of humic substances were taken to evaluate the aggregation efficiency. The results obtained by the aggregation efficiency measurements show that the intensity of agitation, with the assistance of perforated baffle-type flocculation chamber, attains a low level of velocity gradient (G=22–113 s−1), in contrast to the optimized velocity gradient level (G=200–250 s−1). The aggregates formed in the water treatment plant have an unsuitably wide size-distribution.

Abstract - PT. Chemco Harapan Nusantara (PT CHN) requires large amounts of clean water to be used as process water in production process activities. The total need for clean water for all production processes is 10.450 m3 / month. PT CHN can produce products of value from the use of clean water. Besides that, it also produces waste water which can pollute the environment. The purpose of this research is to apply the wastewater recycling method at PT CHN so as to reduce adverse environmental effects due to waste water disposal and generate economic savings, especially during the Covid Pandemic19. The application of this method is done by treating wastewater in a wastewater treatment plant, then reprocessing the water in a clean water treatment plant. The processed water obtained is then distributed to each of the clean water user production processes. The method used in this study is to interview and survey directly on site and then analyze the results of research with data analysis techniques coding, entering, cleaning, display and analyzing. Based on the results of the study showed that the application of the wastewater recycling method is able to convert all wastewater into clean water that can be used for the production process, so it does not pollute the environment. This is evident that in the process all wastewater is put into a wastewater treatment plant which is then treated again at the WTP and the treated water from the WTP is reused as process water. The application of the wastewater recycling method conducted by PT CHN can also be economically profitable, namely by being able to reduce the use of Jababeka's WTP water by 77,5%, thereby being able to save on the cost of water purchase expenses of Rp 99.187.652 / month.

Clean Water

Water is one of the important components of human life or other living things. With the increasing number of residents, the need for clean water has also increased. However, this increase in demand is not offset by the availability of clean water due to the lower quality of water produced by the water treatment plant. Therefore, it is necessary to do alternative water treatment so that clean water needs can be sufficient. One method of processing clean water that can be done is the Jar test method. This study aims to determine the effect of coagulant dose addition on water quality parameters including pH, turbidity, TDS and total hardness of the Manisrejo City Madiun well water sample after water treatment. The research method is carried out through three stages, namely the preparation stage, the instrument analysis stage and the experimental stage. Where the type of coagulant used is Poly Aluminum Chloride (PAC). From the research that has been done, the optimum PAC coagulant dose is 43 mg / l. The conclusion obtained in this study is that the greater the coagulant dose added to the water sample, the smaller the pH value, the value of turbidity, the TDS value and the total hardness of the water sample.

To develop a method for screening ageing of water supply systems by analysing the supplied water's quality, water samples were collected from a water treatment plant, a delivery pump station, two distribution reservoirs and two feed pipes along a water pipe system. Principal component analysis of the water was conducted. In the first principal component, many elements exhibited high factor loadings, whereas the major contributor for the second principal component was iron (Fe). The unlined steel pipe, which was beyond its working lifetime, had a significantly high Fe content in suspended solids. X-ray absorption fine structure (XAFS) analysis showed differences in the abundance ratios of Fe3O4 and α-FeOOH among the sampling points. It was concluded that the concentration and speciation of Fe in supplied water can be a useful index for detecting the ageing of pipes.
