Feasibility study of coagulation system to greywater treatment and economical comparison with electrocoagulation in mining areas
Coagulants exert a significant influence on removing turbidity, TSS and COD. This study has examined the effects of poly-aluminium chloride (PAC), aluminium sulphate (alum) and ferric chloride on removal of turbidity, TSS, COD from greywater in residential complexes of miners working in decorative stone mines. Also, a comparison was undertaken with the electrocoagulation system to find out whet...
متن کاملLong-Term Comparison of Disinfection By-Product Formation Potential in a Full Scale Treatment Plant Utilizing a Multi-Coagulant Drinking Water Treatment Scheme
A comparative study of two coagulants, aluminum sulfate (Alum) and aluminum chlorohydrate (ACH), used in parallel in a full scale water treatment plant (WTP) in Ohio from October 2009 to December 2012, was conducted to determine disinfection by-product (DBP) formation potential removal based on both dissolved organic matter (DOM) and fluorescence-derived metrics. Water quality parameters and fl...
متن کاملEnhanced coagulation using a magnetic ion exchange resin.
The objective of this investigation was to examine the effectiveness of a magnetic ion exchange resin (MIEX) to enhance the coagulation of disinfection by-product precursors in nine surface waters, each representing a different element of the USEPA's 3 x 3 enhanced coagulation matrix. The effect of MIEX-pretreatment on the requisite alum dose needed for subsequent coagulation of turbidity was a...
متن کاملEvaluating the Efficiency of Tragacanth Coagulant Aid in Removing Colloidal Materials and Suspended Solids Creating Turbidity from Karun River Water
Introduction: Colloidal materials and suspended solids cause turbidity in water. To remove turbidity, clarification method is used that includes processes of coagulation, flocculation, and sedimentation. Due to the long duration of coagulation process, coagulant aids are applied. Despite the favorable efficiency of synthetic polyelectrolytes as a coagulant aid, due to their harmful effects on h...
متن کاملEvaluation of Ferric Chloride and Alum Efficiencies in Enhanced Coagulation for Toc Removal and Related Residual Metal Concentrations
Although the removal of colloidal particles continues to be an important reason for using coagulation, a newer objective, the removal of natural organic matter (NOM) to reduce the formation of disinfection by-products (DBPs), is growing in importance. Enhanced coagulation is thus introduced to most water utilities treating surface water. Bench-scale experiments were conducted to compare the eff...
