The present study focuses on the discussion over the parameter of Artificial Neural Network (ANN). Sensitivity analysis is applied to assess the effect of the parameters of ANN on the prediction of turbidity of raw water in the water treatment plant. The result shows that transfer function of hidden layer is a critical parameter of ANN. When the transfer function changes, the reliability of pre...

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...

This paper describes the use of ocean color remote sensing data from the Moderate Resolution Imaging Spectroradiometer (MODIS) onboard the Aqua satellite to characterize turbidity in Lake Okeechobee and its primary drainage basins, the Caloosahatchee and St. Lucie estuaries from 2002 to 2010. Drainage modification and agricultural development in southern Florida transport sediments and nutrient...

Cupuaçu (Theobroma grandiflorum Schum) is an Amazonian Basin native fruit whose fruit pulp is consumed as a juice which presents high density, viscosity, and turbidity. Pectic enzymes, usually yielded by microorganisms, are used to reduce the juice viscosity and turbidity. The present study aims to evaluate the use of pectic enzymes when processing cupuaçu juice. The cupuaçu juice was obtained ...

Turbidity currents are underflows responsible for sediment deposits that generate geological formations of interest for the oil and gas industry. libMesh-sedimentation is an application built upon the libMesh library to simulate turbidity currents. In this work, we present the integration of libMesh-sedimentation with in situ visualization and in transit data analysis tools. DfAnalyzer is a sol...

We have been studying the turbidity estimation for Lakes Shinji and Nakaumi, Shimane Prefecture Japan using satellite sensors. Recently, we have developed a turbidity monitoring system for this area using near-real-time MODIS 250-m resolution band reflectance data which have been provided from Japan Aerospace Exploration Agency (JAXA). MODIS sensors on-board the Terra and Aqua satellites visit ...

Water disinfection is a vital control-point to minimize transmission of diverse pathogens from water sources or produce within and among lots at harvest, during initial postharvest handling, and within subsequent postharvest re-packing and processing. The use of ClO2 as an alternative to NaClO for water disinfection is being adopted by the fresh tomato postharvest handling industry. Lack of dat...

Background & Aims of the Study: Drinking polluted water can transmit diseases, so potable water treatment is one of the most challenging and complex systems in countries. Continuous monitoring for evaluation process in water treatment plant is important. This study aims to investigate performance evaluation of Qom water treatment plant to remove turbidity and coliform in 2005 - 2014. Materia...

This study develops a sedimentation process model that simulate the effects of inflow water quality, treatment flow rate and outflow water quality. The model uses transfer function ARIMA (Auto-Regressive Moving Average) for reflecting the dynamic characteristics of the system The sedimentation model for outflow water turbidity are separated into low and high turbidity by input variables, turbid...
