 ABSTRACT This research is focused on characterization of activated carbon from solid waste CPO industries and applying for treatments of gambut water for iron removal in aqueous media. Key parameters in the present study include TSS, DO, pH and total phenol is also determinated. Methods of sampling and analytical techniques for measuring key parameters are by using extended method. The small model has been developed by combining of the composting and adsorption technology.  The coagulant material such as filter alum, soda caustic, and calcium hypochlorite in any ratios are varied and the optimum condition is achieved. The activated carbon is used as adsorbent by using column model. The overall results show that after coagulation and adsorption processes the total iron, TSS, DO and pH are under threshold levels (Indonesian Regulation) and suitable for drinking water meanwhile other parameters are still uncovered in this investigation. Tentatively, it can be concluded that the proposed gambit water design has achieved the optimum condition. A further study on the improvement of the treatment design and service time for adsorption process is still in progress. Keywords : total iron, gambut water, activated carbon, combining model.

The main aim of the research was to develop a complementary analytical approach consisting of bespoke speciation analysis and non-targeted speciation analysis of As, Sb, and Cr in flavored bottled drinking water samples using HPLC/ICP-DRC-MS and ESI-MS/MS. The scope of two previously developed analytical procedures, (1) multielemental speciation procedure for AsIII, AsV, CrVI, SbIII, and SbV analysis and (2) arsenic speciation procedure for AsB, AsIII, DMA, MMA, and AsV quantification, was extended to the analysis of a new sample type in terms of bespoke speciation analysis. As for the non-targeted speciation, analysis size exclusion chromatography was used with ICP-MS and a complementary technique, ESI-MS/MS, was used for the organic species of As, Sb, and Cr screening. Full validation of procedures 1 and 2 was conducted. Procedure 1 and 2 were characterized with precision values in the range from 2.5% to 5.5% and from 3.6% to 7.2%, respectively. Obtained recoveries ranged from 97% to 106% and from 99% to 106% for procedures 1 and 2, respectively. Expanded uncertainties calculated for procedures 1 and 2 ranged from 6.1% to 9.4% and from 7.4% to 9.9%, respectively. The applicability of the proposed procedures was tested on bottled drinking water samples. Results for the real samples in procedure 1 were in the range from 0.286 ± 0.027 [μg L−1] to 0.414 ± 0.039 [μg L−1] for AsIII, from 0.900 ± 0.083 [μg L−1] to 3.26 ± 0.30 [μg L−1] for AsV, and from 0.201 ± 0.012 [μg L−1] to 0.524 ± 0.032 [μg L−1] for SbV. CrVI and SbIII were not detected in any sample. As for procedure 2, results were in the range from 0.0541 ± 0.0053 [μg L−1] to 0.554 ± 0.054 [μg L−1] for AsB. Results for AsIII and AsV obtained with procedure 2 were in good accordance with results obtained with procedure 1. DMA and MMA were not detected in any sample.

Detailed analysis of household generated greywater (GW) samples is an essential task for the design of treatment systems before reuse. In this paper modern analytical methods will be discussed, which were applied to determine the ionic and elemental concentration of different GW samples. Ion chromatography (IC) and Microwave plasma atomic emission spectrometry (MP-AES) methods were used to spoor the composition of GW samples. It was shown that from the IC results and from calculated parameters (Na ee% and SAR) the application of raw or treated GW flows for irrigation is controlled. According to the elemental concentration, GW samples from laundry/kitchen sink and dishwasher proved to be the most contaminated compared to drinking water, while the concentration of the measured elements did not elevate as significantly in GW samples from shower/bathtub.

Most drinking water industries are closely examining options to maintain a certain level of disinfectant residual through the entire distribution system. Chlorine dioxide is one of the promising disinfectants that is usually used as a secondary disinfectant, whereas the selection of the proper monitoring analytical technique to ensure disinfection and regulatory compliance has been debated within the industry. This research endeavored to objectively compare the performance of commercially available analytical techniques used for chlorine dioxide measurements (namely, chronoamperometry, DPD (N,N-diethyl-p-phenylenediamine), Lissamine Green B (LGB WET) and amperometric titration), to determine the superior technique. The commonly available commercial analytical techniques were evaluated over a wide range of chlorine dioxide concentrations. In reference to pre-defined criteria, the superior analytical technique was determined. To discern the effectiveness of such superior technique, various factors, such as sample temperature, high ionic strength, and other interferences that might influence the performance were examined. Among the four techniques, chronoamperometry technique indicates a significant level of accuracy and precision. Furthermore, the various influencing factors studied did not diminish the technique's performance where it was fairly adequate in all matrices. This study is a step towards proper disinfection monitoring and it confidently assists engineers with chlorine dioxide disinfection system planning and management.

Bottled Mineral Water

Project management is a new thing with the development of two analytical techniques used for planning, scheduling, and decision making on projects to be carried out so that they can be carried out optimally and efficiently. These two analytical techniques are the Critical Path Method (CPM) and Project Evaluation and Review Technique (PERT). Network optimization for the project is very important for the production of with "Aeta" brand Bottled Mineral Water produced by drinking water company in Madiun. This optimization is carried out in order to find out the production schedule of bottled water, there are 4 packages produced namely cups, 1.5 L bottles, 600 ml bottles, and gallons. After scheduling using the Critical Path Method, ie bottled water production will be more profitable if more products are in Gallon packaging. Because the Gallon packaging will save time this happens because the Gallon packaging does not go through cardboard packaging.
