Integrated Water Quality Testing Device

2018

In recent days, the most important problem that our society faces is water scarcity. Due to contamination of water bodies, drinking water supply, water for agriculture and healthy fisheries has been severely impaired. Over five millions of people die annually from water borne diseases. It has also lead to contamination of marine ecosystems and decrease in crop yields. Unavailability of easy water quality detector has been a major cause which has led to all above mentioned problems. An autonomous, real time and integrated device is designed to measure physical and chemical properties of water. Designed device uses sensors to detect the quality parameters (pH, temperature, turbidity, conductivity). Sensor outputs are processed by Arduino Uno, which sends parameter values to authenticated user via GSM module. Although there are existing methods to detect quality of water, an integrated device is designed which can be used in all the three fields.

Proceedings of the International Conference on Self Sustainable Artificial Intelligence Systems (ICSSAS 2023), 2023

Water is an essential part of living organisms. The Industrialization has caused immense contamination of potable water. Hence water quality monitors play an important role in detection of contamination in these water bodies. There are many water quality monitors available in the market for the detection of level of contamination. This research study discusses about the effective usage of Arduino UNO board, sensors to measure temperature, TDS and pH to measure the water quality. Hence, the main aim of this research study is to find the TDS, temperature and pH of the water samples collected from various places in Bangalore City, Karnataka, and conclude regarding the quality of the water whether it is portable to use for drinking and domestic purpose.

An Open Source Water Quality Measurement System for Remote Areas

Engineering Proceedings, 2021

The unavailability of safe drinking water leads to poor conditions related to mental and physical health. To quantify the quality of water, laboratories testing the water are present in major cities which assess the basic quality parameters of drinking water, e.g., total dissolved salts (TDS), ion concentration (conductivity), turbidity, and pH value as recommended by the World Health Organization (WHO). The unavailability of such testing laboratories at remote locations makes the testing of the drinking water difficult. Establishing such laboratories is a tedious job as it requires a lot of costly equipment and specially trained personnel to operate them, making them difficult to handle. To address these issues, a water quality monitoring system for remote areas was designed which is capable of measuring basic measurable qualities of salt concentration, ion concentration, turbidity, and pH value. With the utilization of such a system, the user can qualify the water present in the v...

Given the significant obstacles that water pollution poses to the principles of green globalisation, it is more important than ever to guarantee a reliable and safe source of drinking water. This research presents a practical and affordableapproach to meet this need by proposing a real-time waterquality monitoring system that makes use of the Internet ofThings (IoT). The proposed system effectively incorporates awide range of sensors that are specifically designed to monitor physical and chemical parameters that are critical for assessingthe quality of water.

A Review on Water Quality Monitoring Methods Based on Electronics and Optical Sensing

Journal of Advanced Research in Applied Sciences and Engineering Technology

Water pollution is a detrimental issue that can affect health, economy, society, flora, and fauna. Monitoring water quality is important to mitigate water pollution issues. The purpose of this research is to investigate several water quality monitoring methods based on electronics and optical sensing. Electronics and optical sensing are among common and popular methods used to monitor water quality. The smart platform is used to work together with electronics and optical sensors to assist users in controlling the system. Both methods have their own benefit such as electronics sensing being portable and easy to handle whereas optical sensing does not affect the water sample, leading to higher accuracy results. Thus, the selection of the suitable method depends on the consumer’s requirement, cost, budget, and time.

Surface Water Quality Analysis & Real Time Monitoring System

Journal of emerging technologies and innovative research, 2019

As for every parameter of water quality, we have traditional method to test water quality. The conventional method of testing water quality involves gathering water manually and sending it to the laboratory to test and analyze various parameters of water. This method is time taking i.e. wastage of man hours, energy and highly expensive. Also there is a need to improve water quality monitoring system to identify whether the determined water quality is suitable for purposed used. So we have to solve this problem by using automatic real-time water quality analysis and reporting using SCADA. Initially we are focusing on review of this area. For water quality analysis we have consider basic parameters of water like Temperature, pH, Dissolved Oxygen and Turbidity. So this paper is only for selection of various better sensors. We present in this paper the comparison of various sensors with its required graph and output. This paper is helpful to select the precise and good quality of sensors.

Advancements in Monitoring Water Quality Based on Various Sensing Methods: A Systematic Review

International Journal of Environmental Research and Public Health

Nowadays, water pollution has become a global issue affecting most countries in the world. Water quality should be monitored to alert authorities on water pollution, so that action can be taken quickly. The objective of the review is to study various conventional and modern methods of monitoring water quality to identify the strengths and weaknesses of the methods. The methods include the Internet of Things (IoT), virtual sensing, cyber-physical system (CPS), and optical techniques. In this review, water quality monitoring systems and process control in several countries, such as New Zealand, China, Serbia, Bangladesh, Malaysia, and India, are discussed. Conventional and modern methods are compared in terms of parameters, complexity, and reliability. Recent methods of water quality monitoring techniques are also reviewed to study any loopholes in modern methods. We found that CPS is suitable for monitoring water quality due to a good combination of physical and computational algorit...

Measuring, Modeling Water Quality by Using Sensors and Statistical Analysis Techniques

2013

Water quality is measured based on the study of several parameters for different water sources. Three different sources of water are studied in Alexandria (Egypt): Mediterranean Sea, Mariot Lake, and mineral water. The measured parameters are: Sodium (Na), Magnesium (Mg), Calcium (Ca), Nickel (Ni), in addition to pH, conductivity and temperature. The measured values are compared with the standard of water parameters given by the World Health Organization (WHO). Different devices and sensors are used in measurements which are:ICP-7500 sequential plasma Spectroscopy SHIMADZU, ASTM D1126-02, ASTM D5708-11, ASTM D4191-08, ASTM D1125-95, ASTM D4191-08, ASTM D1293-99, in addition to colorimetric and potentiometric sensors. The linear regression model based on these parameters is extracted, and the coefficients are calculated by using three statistical analysis methods namely: regstat, roubustfit, and curve fitting. The predicted values of the concentrations from the linear regression models are compared with the measured values, and the root mean square error (RMS) is calculated. The principal component analysis (PCA) method is applied for clustering the three sources of water according to the values of measured parameters. The results indicate that, Mediterranean Sea is recommended as an alternative source. Mariot Lake is contaminated to a high degree.
