In this paper the design and development of a turbidity system for monitoring drinking water quality in households is presented. Its operation is based on the principle that the intensity of the light scattered by the suspended matter is proportional to its concentration. Unlike the commercially available turbidity meters, which are relatively expensive and bulky, the proposed device is small-s...

Mobile particles play crucial roles for contaminant transport in karst aquifers, but few studies have investigated the relationships between sediment dynamics and contaminants. This is partly due to the diffi culty in monitoring suspended particles: Turbidity is easy to measure but does not deliver detailed information on the size and type of particles; mineralogical laboratory analyses are lab...

The ~roblem of assessment of atmospheric turbidity caused by aerosol particles, vie., dust, smoke, haze, and other atmospheric pollutants, apart from the effect of variable water vapour content of the atmosphere, has been studied efreeh. The basic concept mderlying Linke's turbidity factor, T , has been found to be theoretically sound, dthough its quantitative formulation suffers from one major...

—Environmental factors such as turbidity and habitat complexity affect many aspects of aquatic food webs, including predator–prey interactions. We examined the effects of turbidity (0, 5, 10, 20, 40 nephelometric turbidity units [NTU]) and cover (presence or absence) on prey selection by adult smallmouth bass Micropterus dolomieu (mean 6 SD 1⁄4 290 6 41 mm total length) in laboratory pools. Ind...

Abstract Background and purpose: According to the reported problems in area of the inappropriateness of water quality which used for washing and staining of car apparatuses in a car factory, this research was carried out for identification of physical, chemical, and microbiological characteristics of the consumed water in Babol car factory, Iran. Materials and Methods: Physical and chemical par...

Background & Aims of the Study:  Lack of access to safe drinking water can lead to undesirable aesthetic problems and adverse health effects such as infectious diseases. The aim of this study was to investigate the microbiological quality of the drinking water distribution network in Divandareh City (Kordestan-western Iran). Materials & Methods:  This study was ...

Water scarcity encourages researchers to keep working on natural coagulant agents such as Moringa oleifera seed extract, that could be used even in developing countries. With this scope, this investigation is focused on the optimization of certain parameters affecting the use of this coagulant product in the clarification of real surface water. Acidic pH levels seem to enhance the coagulation p...

This study examines the impacts of storm-triggered landslides on downstream sediment and turbidity responses in the Gaoping River Basin, Taiwan using the Soil and Water Assessment Tool (SWAT). Attention is given to analyzing the increased and altered baseline of suspended sediment load and turbidity after the disturbances caused by the rainfall and landslides associated with Typhoon Morakot in ...

Light-emitting diodes can function as spectrally selective detectors in a miniature, inexpensive sun photometer that measures atmospheric turbidity and precipitable water.

Resource agencies, private landowners, and citizen monitoring programs utilize turbidity (water clarity) measurements as a water quality indicator for total suspended solids (TSS – mass of solids per unit volume) and other constituents in streams and rivers. The dynamics and relationships between turbidity and TSS are functions of watershed-specific factors and temporal trends within storms and...
