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

Laboratory Methods

На водопроводных очистных сооружениях дезинфекция воды с применением хлора, наряду с ее фильтрованием, является исторически самым старым и потому рутинным технологическим процессом. Практика управления процессом дезинфекции, складывающаяся на сооружениях в течение многих лет, часто основывается на не вполне обоснованных, а иногда и на ошибочных решениях, принятых в прошлом. Главными ориентирами, как правило, являются только нормируемые параметры: остаточная концентрация хлора и микробиологические показатели на выходе станции. Между тем расположение точек ввода реагентов, их начальные концентрации и режим дозирования имеют ключевое значение с точки зрения эффективности, надежности и безопасности технологии. Точность и оперативность контроля концентраций реагентов, контроль эффективности связывания хлора в случае аммонизации воды являются определяющими факторами при автоматизации процесса. Традиционно и формально программы производственного контроля базируются на лабораторных методах, разработанных еще в начале ХХ века. В то же время прогресс в аналитическом приборостроении позволяет вести контроль технологических параметров дезинфекции в режиме реального времени. Представлены результаты опытно-промышленных испытаний оптимизации процессов хлораммонизации на основе онлайн-контроля качества воды. Испытания проведены на Южной водопроводной станции ГУП «Водоканал Санкт-Петербурга». Выполнен анализ лабораторных методов контроля концентрации активного хлора и азотсодержащих веществ с точки зрения обеспечения достоверной оценки физико-химических процессов хлораммонизации. Дана оценка возможностей современных анализаторов для повышения эффективности, точности и безопасности методов управления процессом хлораммонизации. Во введении приведены некоторые значимые события в истории развития технологии дезинфекции воды в России и в мире. Disinfection of water with chlorine, along with the filtration at water treatment facilities has been historically the oldest and therefore routine technological process. The practice of disinfection process control that has been developed at the facilities over many years is often based on not exactly justified, and sometimes on erroneous, decisions made in the past. The main reference points, as a rule, are only regulated parameters, i. e., residual chlorine concentration and microbiological indicators at the outlet of the facilities. Meanwhile, the location of the chemical injection points, initial concentrations of chemicals and the dosing rate are of key importance from the point of view of the technology efficiency, reliability and safety. Accuracy and efficiency of chemical concentration control, control of the chlorine binding efficiency in the process of water ammoniation are the decisive factors in the process automation. Traditionally and formally, production control programs are based on the laboratory methods developed back in the early twentieth century. At the same time, progress in analytical instrumentation provides for monitoring the process parameters of disinfection in real time mode. The results of pilot tests of optimizing chlorammoniation processes based on online water quality monitoring are presented. The tests were carried out at the Southern Water Treatment Plant of SUE «Vodokanal of St. Petersburg». The analysis of the laboratory methods for monitoring the concentration of active chlorine and nitrogen-containing substances from the point of view of ensuring a reliable assessment of the physicochemical processes of chlorammoniation has been carried out. An assessment of the capabilities of modern analyzers for improving the efficiency, accuracy and safety of methods for controlling the chlorammoniation process is given. Some significant events in the history of the development of water disinfection technology in Russia and in the world are given in the Introduction.

The trans-boundary area between the Europe Union and other countries is highly susceptible to changes in water quality and variations in the potential pollution load that could influence its eco-systems significantly. The Neris (Viliya) River is one of the biggest surface water bodies in Lithuania and Belarus with an ecologically important area protected by international legislation. The study was aimed at evaluating the impacts of integrated pollution on water quality of the Neris River taking into account different storm-water flows and ecological scenarios. For this purpose, qualitative and quantitative statistical evaluation was set up and calculation was done; different integrated pollution loads of the catchment area were estimated. The evaluation considered a decrease in river discharge due to changes in the regional storm-water flow and technological development that should lead to the growing covered surface and a reduction in the untreated storm-water flows. The obtained results indicated that, in the case of storm-water treatment, the total nitrate and phosphate concentrations will decrease, while in the cases of changes in combined suspended solid, the concentration of nutrients will decrease. Thus, a trans-boundary storm-water treatment plant of the Viliya River is required as it should eliminate pollution accumulation and restore its acceptable environmental status. A coordinated international project for the entire catchment of the Neris (Viliya) River based on the specifications and requirements of the EU Water Framework Directive (EU 2000) should be developed and implemented. Subsequently, ecological river-use policies should be established at the international level, which should offer considerable perspectives for the sustainable development of the area.

Smart Water

The deteriorating water environment demands new approaches and technologies to achieve sustainable and smart management of urban water systems. Wireless sensor networks represent a promising technology for water quality monitoring and management. The use of wireless sensor networks facilitates the improvement of current centralized systems and traditional manual methods, leading to decentralized smart water quality monitoring systems adaptable to the dynamic and heterogeneous water distribution infrastructure of cities. However, there is a need for a low-cost wireless sensor node solution on the market that enables a cost-effective deployment of this new generation of systems. This paper presents the integration to a wireless sensor network and a preliminary validation in a wastewater treatment plant scenario of a low-cost water quality monitoring device in the close-to-market stage. This device consists of a nitrate and nitrite analyzer based on a novel ion chromatography detection method. The analytical device is integrated using an Internet of Things software platform and tested under real conditions. By doing so, a decentralized smart water quality monitoring system that is conceived and developed for water quality monitoring and management is accomplished. In the presented scenario, such a system allows online near-real-time communication with several devices deployed in multiple water treatment plants and provides preventive and data analytics mechanisms to support decision making. The results obtained comparing laboratory and device measured data demonstrate the reliability of the system and the analytical method implemented in the device.

Plant Operation

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.

Unit Process

The quality of Klang river water is deteriorating dramatically since it is in urban places every day and become one of the major problems.  Therefore, the Malaysian government had initiated one river cleaning project named River of Life (ROL) project. This project is for rehabilitating and restoring the Klang river. A series of river water treatment plant (RWTP)s have been operated in Klang river catchment since 2014. Six RWTPs station has been monitored up to eight stations until presents. Eight parameters consisting of physio-chemical types and biological types have been recorded. RWTP effluent discharges are targeted to achieve Malaysia Interim National Water Quality Standard (INWQS) under Class II B. Since previous RWTP performance only emphasized on local river pollutants and certain conditions, this paper will investigate the effectiveness of full-scale RWTP unit process for river condition. Water quality assessment are involved which are consist of effluent water quality monitoring and pollutant removal efficiency. Most of the major pollutants able to be reduced by more than 50% reduction. Although BOD and AN still not able to achieve standard range gazetted by INWQS Class IIB, there is an improvement of river water quality at Klang River by using IFAS technology adopted in the RWTP system.
