Purpose – This paper aims to present a review of the design and development of the turbidimeter for measuring the turbidity level in water. Monitoring the turbidity level of water is important because it is related to public health. Design/methodology/approach – A precise and reliable turbidimeter can provide vital data that reveals the water condition level. Several turbidimeter units are discussed briefly. Three types of turbidimeter design – single beam, ratio and modulated four beams – are elaborated with some illustrations of the design concept. Various improvements and innovations for upgrading turbidimeter design are also discussed. Findings – This paper elaborated on a new method of estimating the water turbidity level in water samples using an optical tomography system based on the independent component analysis method. The results showed that a tomography-based turbidimeter can measure slight changes in the level of turbidity when the volume of contaminants is changed slightly. The turbidimeter ...

This paper presents the results of concentration profiles for gas bubble flow in a vertical pipeline containing contaminated water using an optical tomography system. The concentration profiles for the bubble flow quantities are investigated under five different flows conditions, a single bubble, double bubbles, 25% of air opening, 50% of air opening, and 100% of air opening flow rates where a valve is used to control the gas flow in the vertical pipeline. The system is aided by the independent component analysis (ICA) algorithm to reconstruct the concentration profiles of the liquid-gas flow. The behaviour of the gas bubbles was investigated in contaminated water in which the water sample was prepared by adding 25 mL of colour ingredients to 3 liters of pure water. The result shows that the application of ICA has enabled the system to detect the presence of gas bubbles in contaminated water. This information provides vital information on the flow inside the pipe and hence could be very significant in increasing the efficiency of the process industries.

This paper presents an investigation on the design of an optical tomography system for monitoring the water quality in the pipeline. The Independent Component Analysis (ICA) method has been utilised in this system in order to get the turbidity material (M) which represents the quality and the darkness of water. Comparison has been made between 3 litres of pure water samples and contaminated water samples in terms of average values (K) that related to turbidity material (M) on the 18 × 18 pixel tomogram. The sample of contaminated water is provided by adding 35 millilitres (ml) of food colouring into the pure water. Eighteen transmitters and eighteen receivers have been installed around the pipe whose outputs were then inputted into signal conditioning circuit and data acquisition system for data analysing process. The result has revealed that the system has the potential to contribute in the field of water quality monitoring or water treatment process.
