ABSTRACTThe need for clean water consumption continues to increase in line with the current population and industry growth. The canned industry is one of the industries that consume a considerable amount of water for the production process, while the availability of clean water sources is very limited, both in quantity and quality. One alternative solution to the problem above is by building a wastewater treatment plant into reusable water (recycling) to meet the needs of the washing process in the industry. This paper discusses the testing of wastewater recycling installations into clean water in a canned industry in Jakarta. The process of recycling wastewater is divided into several stages, namely chemical processes for pH control, biological processes of activated sludge, biofilter, and filtration. Afterward, the wastewater is filtered using a reverse osmosis membrane. The test results show that the water quality of recycling wastewater and filtered wastewater using RO membranes could produce pure water quality. The use of water for the process in the canned industry is large enough for canned washing processes. Therefore, by using the recycling technology, the use of water, especially for the washing process, can be saved up to 100%.Keyword : wastewater reuse, reverse osmosis, can industriesABSTRAKKebutuhan akan konsumsi air bersih terus meningkat sejalan dengan pertumbuhan penduduk dan industri saat ini. Industri kaleng merupakan salah satu industri yang mengkomsumsi air dalam jumlah yang cukup banyak untuk proses produksi, sedangkan  ketersediaan sumber air bersih sangat terbatas, baik secara kuantitas maupun kualitas.

A pilot-scale plant was employed to validate the performance of a proposed full-scale advanced water treatment plant (AWTP) in Sydney, Australia. The primary aim of this study was to develop a chemical monitoring program that can demonstrate proper plant operation resulting in the removal of priority chemical constituents in the product water. The feed water quality to the pilot plant was tertiary-treated effluent from a wastewater treatment plant. The unit processes of the AWTP were comprised of an integrated membrane system (ultrafiltration, reverse osmosis) followed by final chlorination generating a water quality that does not present a source of human or environmental health concern. The chemical monitoring program was undertaken over 6 weeks during pilot plant operation and involved the quantitative analysis of pharmaceuticals and personal care products, steroidal hormones, industrial chemicals, pesticides, N-nitrosamines and halomethanes. The first phase consisted of baseline monitoring of target compounds to quantify influent concentrations in feed waters to the plant. This was followed by a period of validation monitoring utilising indicator chemicals and surrogate measures suitable to assess proper process performance at various stages of the AWTP. This effort was supported by challenge testing experiments to further validate removal of a series of indicator chemicals by reverse osmosis. This pilot-scale study demonstrated a simplified analytical approach that can be employed to assure proper operation of advanced water treatment processes and the absence of trace organic chemicals.

Abstrak - PT. Chemco Harapan Nusantara (PT CHN) membutuhkan air bersih dalam jumlah besar untuk digunakan sebagai air proses dalam kegiatan proses produksi. Adapun total kebutuhan air bersih untuk semua proses produksi yaitu sebanyak 10.450 m3/ bulan. PT CHN dapat menghasilkan produk yang bernilai jual dari penggunaan air bersih tersebut. Di samping itu juga menghasilkan air limbah yang dapat mencemari lingkungan. Tujuan dari penelitian ini adalah untuk menerapkan metode daur ulang air limbah pada PT CHN sehingga dapat mengurangi dampak buruk bagi lingkungan akibat pembuangan air limbah dan menghasilkan penghematan secara ekonomi terutama pada saat Pandemi Covid19 ini. Penerapan dari metode tersebut dilakukan dengan cara mengolah air limbah di dalam instalasi pengolahan air limbah, kemudian mengolah kembali air tersebut di dalam instalasi pengolahan air bersih. Air olahan yang diperoleh kemudian di distribusikan ke masing-masing proses produksi pemakai air bersih. Metode yang digunakan dalam penelitian ini adalah dengan wawancara dan survei secara langsung di lokasi kemudian menganalisis hasil penelitian dengan teknik analisa data coding, entering, cleaning, display dan analyzing. Berdasarkan hasil penelitian menunjukkan bahwa penerapan metode daur ulang air limbah mampu mengubah seluruh air limbah menjadi air bersih yang dapat digunakan untuk proses produksi , sehingga tidak mencemari lingkungan. Hal tersebut terbukti bahwa pada prosesnya seluruh air limbah dimasukkan ke dalam instalasi pengolahan air limbah yang kemudian diolah lagi di WTP dan air hasil olahan dari WTP tersebut digunakan kembali sebagai process water. Penerapan metode daur ulang air limbah yang dilakukan oleh PT CHN juga dapat menguntungkan secara ekonomi yaitu dengan dapat mengurangi pemakaian air WTP Jababeka sebesar 77,5 %, sehingga mampu menghemat biaya pengeluaran pembelian air sebesar Rp 99.187.652 /bulan. 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.

Israel is a semi-arid country with insufficient natural water resources. Wastewater effluent reuse and desalination have become the main source of water to compensate for the future water shortage. Today, between 65 and 70% of wastewater of urban and industrial origin is reused in agriculture after treatment in biological treatment plants around the country. The Dan Region Reclamation Project (Shafdan) is the largest wastewater treatment and reclamation project in Israel. 130 Mm3/yr of reclaimed water is used for unrestricted irrigation after soil aquifer treatment (SAT). Extensive water quality monitoring is performed to keep an efficient and safe wastewater reuse system. After 25 years of operation, the Shafdan deals with the following operational issues on an ongoing basis: Biofouling of the effluent pipelines from the wastewater treatment plant to the SAT, and a lack of capacity in the SAT system. Biofilm growth in the pipelines is controlled by intermittently applying chlorine based compounds at a 10 mg/L dosage for a few hours.

The formation of N-nitrosodimethylamine (NDMA) is of major concern among wastewater recycling utilities practicing disinfection with chloramines. The NDMA formation potential (FP) test is a simple and straightforward method to evaluate NDMA precursor concentrations in waters. In this paper we show the NDMA FP results of a range of tertiary wastewater treatment plants that are also the source for production of recycled water using an Ultrafiltration – Reverse Osmosis (UF-RO) membrane process. The results indicate that the NDMA FP of different source waters range from 350 to 1020±20 ng/L. The fate of these NDMA precursors was also studied across the different stages of two Advanced Water Treatment Plants (AWTP) producing recycled water. These results show that more than 98.5±0.5% of NDMA precursors are effectively removed by the Reverse Osmosis (RO) membranes used at the AWTPs. This drastically reduces any potential for re-formation of NDMA after the RO stage even if chloramines may be present (or added) there.

The impact of the As Samra wastewater treatment plant upgrade on the quality of the Zarqa River (ZR) water was investigated. Time series data that extend from October 2005 until December 2009 obtained by a state-of-the-art telemetric monitoring system were analyzed at two monitoring stations located 4 to 5 km downstream of the As Samra effluent confluence with the Zarqa River and about 25 km further downstream. Time series data that represent the ZR water quality before and after the As Samra upgrade were analyzed for chemical oxygen demand (COD), electrical conductivity (EC), total phosphorus (TP) and total nitrogen (TN). The means of the monitored parameters, before and after the As Samra upgrade, showed that the reductions in the COD, TP and TN were statistically significant, while no reduction in the EC was observed. Comparing the selected parameters with the Jordanian standards for reclaimed wastewater reuse in irrigation and with the Ayers & Westcot guidelines for interpretation of water quality for irrigation showed that the ZR water has improved towards meeting the required standards and guidelines for treated wastewater reuse in irrigation.

Water Taste

Takabonerate  is one of the 23 regencies in South Sulawesi where it is locates at the southern parth of South Sulawesi Province and it is surrounded by flores sea. As maritime regency, its mainland is 1,188.28 km2 (5.23%) and the sea is approximately 21,138.41 km2 (94.68%). It has 126 islands wich consist of small and big islands.  Tarupa village’s   a subdistrict located in a tidy and peat area. The community living in tarupa use surface water of river as the main clean water resource. The surface water is  influenced by the tide of sea water. The surface water taste is very salty (TDS12000ppm). The use of rain water as the second alternative is very limited, i.e it is only in rainy season. To deal with the chronic problem, such as the lack of clean water supply, it needs an appropriate water treatment technology. The suitable water treatment system is a combination of conventional and advanced technology. Desalination, such as Reverse Osmosis must be involved to reduce salinity of the raw water. A complete process includes the pretreatment and advance treatment. The pretreatment are oxidation and some common filtrations. The advance treatment is a molecular filtration using a membran which the principal is reverse osmosis pressure. If the pilot water treatment plant is avalaible in Tarupa in Takabonerate, the clean water supply will not be a serious problem. Generally, it can also play an important role to increase the social level of community in South Sulawesi.. Kata Kunci : Teknologi, pengolahan, air asin, reverse osmosis, air minum.

Abstract The Water Corporation of Western Australia uses polymeric ultrafiltration (UF) membranes across a range of applications including surface waters with high natural organic matter (NOM), recycling of secondary treated wastewater and pre-treatment for seawater reverse osmosis (SWRO). These challenging raw water conditions require expensive chemical dosing and clean-in-place (CIP) regimes, high frequency of membrane replacement and reduced membrane life. The greater durability of ceramic membranes, with optimal ozone and coagulant dosing, offer a potential capital and operating advantage over polymeric UF membranes. The Water Corporation collaborated with PWN Technologies (PWNT) to establish a ceramic membrane pilot plant at the Beenyup Wastewater Treatment Plant (WWTP). Optimised performance of the pilot plant was established and compared with existing UF membranes treating secondary treated wastewater prior to reverse osmosis (RO) in an indirect potable wastewater recycling application. Findings show a sustainable flux rate of 150 L/m2/h is achievable with ceramic MF membranes while filtering secondary treated wastewater. Higher flux rates up to 250 L/m2/h have been tested and are possibly sustainable, however, other bottlenecks in the pilot plant (ozone generator capacity) prevented longer test runs at this flux. Comparable design flux rates for polymeric UF membranes are 50 L/m2/h.

The need for clean water in big cities is very dependent on water supply by water companies (PDAM). The increasing demand for clean water in big cities is proportional to the increasing of number population and industry, but not comparable to the clean water supply and quality of raw water available. PDAM has made various efforts to improve the quality of clean water services to the community. One of the effort is to improve the performance of water treatment plant (WTP). To support the improvement of the performance of WTP, required water quality monitoring at the intake location in use. This paper discusses the online and realtime water quality monitoring at the water intake location using a multi-probe digital sensor and GSM technology. This observation data is used as a comparative data analysis of laboratory data on raw water source PDAM Taman Kota (Cengkareng Drain). Keywords: air baku air minum, intake PDAM Taman Kota Cengkareng Drain, pemantuan kualitas air, multi probe digital sensor, teknologi online monitoring, Water Treatment Plant

Water Overflow

Clean water is the primary need of living things because water plays an important role in the process of life. The quality of raw water from various sources has different quality and quantity characteristics, which means that not all regions have a clean water supply that can be processed into water suitable for consumption in accordance with clean water standards that meet clean water requirements. Therefore, in processing and utilizing overflow of Sahang River water, the WTP (Water Treatment Plant) system is to remove metals, organic substances and bacteria in accordance with clean water quality standards of the Ministry of Health of the Republic of Indonesia. The stages in the processing and utilization of the Sahang River water overflow are preliminary analysis of samples in the intake, sedimentation and reservoir tanks. Then to ensure the results of processing and utilization of the Sahang river water overflow, we took a comparative sample, namely PDAM Tirta Musi Palembang water. Analysis of physical, chemical and biological parameters. In the analysis test, the physical parameters of clean water include temperature, color, turbidity, dissolved solids (TDS), smell and taste. In the analysis of clean water chemical parameters, including pH, hardness, chloride, organic substances, ammonia, sulfate, nitrite, nitrate, chromium, cadmium, iron, manganese, copper, aluminum, zinc and lead. Meanwhile, the biological parameter analysis test includes the analysis of E-Coli bacteria. The results of the water quality analysis test for WTP (Water Treatment Plant) have been proven to comply with SNI quality standards for clean water with the optimum results obtained in the addition of a coagulant with a concentration of 75 ppm. However, there are parameters that have decreased and increased levels in each type of parameter such as parameters Turbidity (4.27 NTU), pH (7.01), TDS (24.1 ppm), NaCl (49.7 ppm), DO ( 6.95 ppm), Conducto (1.6211 µs) and hardness (13.29 ppm), but it is still within the standard of clean water quality, which means that the Water Treatment Plant (WTP) system is proven to be implemented especially for water purposes.
