This work assesses the efficiency of integrated enhanced coagulation and direct filtration processes for the removal of color, turbidity, and natural organic matter (NOM) from surface water. The processes were conducted in a simulated pilot. The operating conditions of the treatment process, including pH, FeCl3 dose, and influent flow, were investigated. Following that, its efficienc...

one of the principles for designing and using the various units of water treatment plants is ability of assigning and predicting performance of those units in different and various conditions that could be checked by making pilot and could be modeled by means of available programs and software such as artificial neural network. at this study a model provided for predict performance of pressure ...

Several innovative filtration technologies have been developed in the last two decades to decrease the backwash requirements, to increase the water production efficiency, and to improve the operational and design conditions. The Compressible Medium Filter (CMF) also known as the “Fuzzy Filter” involves the use of a synthetic compressible fiber (polyvaniladene) porous material as the filtering m...

Application of a reliable forecasting model for any water treatment plant (WTP) is essential in order to provide a tool for predicting influent water quality and to form a basis for controlling the operation of the process. This would minimize the operation and analysis costs, and assess the stability of WTP performances. This paper focuses on applying an artificial neural network (ANN) approac...

Removal of turbidity, phytoplankton, and zooplankton from ballast water with waste-tire-made crumb rubber filtration was evaluated in this study. The influences of various design, operational, and water quality parameters (filter depth, media size, filtration rate, temperature, turbidity, running time, etc.) on filtration performance were investigated. Statistical approaches were used to develo...

Background: The reuse of treated municipal wastewater is an important source of water for different ,purposes. This study evaluated the efficiency of the electrocoagulation process in removing turbidity,a total suspended solids (TSS), chemical oxygen demand (COD), nitrate, and phosphate from wastewater at the treatment facility in Karaj, Iran. Methods: This experimental study was performed at ...

Abstract Turbidity is a fundamental measure for assessing the quality of water supplied by treatment plants (WTPs) employing conventional process. If it present in amounts exceeding permitted limit, disinfectants are less effective killing microorganisms and becomes unsafe to drink. This article part comprehensive study that aims investigate high-turbidity problem tap two cities Najaf governora...

The occurrence and removal patterns of 24 antimicrobial agents resistant determinants namely 6 antibiotic resistance genes (ARGs) 2 mobile genetic elements (MGEs), the fecal indicator E. coli were investigated in three full-scale wastewater treatment plants. Their waterlines biosolids lines (including secondary based on both granular activated sludge) sampled monthly throughout one year. Sample...

sulfur utilizing autotrophic denitrification synthetic wastewater in up flow packed --bed reactor was evaluated under different concentrations of alkalinity and organic matter. the reactor was filled with granular elemental sulfur particles with diameters of 2.8-5.6 mm and porosity of 40%. the initial culture was prepared from sludge of shahrak ghods wastewater treatment plant. first, the stoic...
