A review on the design and development of turbidimeter

Abstract

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 can also provide a profile of the distribution of the turbidity in the water sample. Originality/value - A turbidimeter based on the optical tomography concept can be a valuable tool in determining the level of pollution in rivers, sea, etc. © Emerald Group Publishing Limited.
