High-speed filtration using highly porous fiber media for advanced and compact particle removal
Since its recent introduction to the filtration industry, one of the major concerns about the use of fiber in water treatment has been its applicability for high-rate filtration while minimizing the build-up of headloss. In this study, a compact, modular filter employing non-woven, highly porous polypropylene fiber as filter media was investigated for the treatment of turbid water under high ...

Home water treatment by direct filtration with natural coagulant
ABSTRACTSeeds of the plant species Strychnos potatorum and Moringa oleifera contain natural polyelectrolytes which can be used as coagulants to clarify turbid waters. In laboratory tests, direct filtration of a turbid surface water (turbidity 15-25 NTU, heterotrophic bacteria 280-500 cfu ml−1, and fecal coliforms 280-500 MPN 100 ml−1), with seeds of S. potatorum or M. oleifera as ...

Laboratory evaluation of a water-treatment sequence using Moringa oleifera seed coagulant
A water extract of Moringa. oleifera seed was applied to a treatment sequence comprising coagulation-flocculation-sedimentation-sand filtration. Model waters (kaolinite suspensions) of turbidities 10, 100, 300 and 700 NTU were prepared. For the 10 NTU water, the optimum dose was only evident when sand filtration was incorporated into the treatment sequence. For the higher water turbidities ...

Application of Direct Filtration to MIEX® Treated River Murray Water
Dissolved natural organic matter (NOM) has been shown to interfere with the coagulation process, particularly with alum (aluminium sulphate) which is the most widely used coagulant in potable water treatment. The additional coagulant demand of the NOM can often be a significant contribution to the overall coagulant dose required for effective turbidity control in conventional water treatment. ...

Comparing plain and coagulated horizontal flow roughing filtration for high turbidity water
In this work, a multi-compartment, horizontal flow roughing filter (HRF) was designed, constructed and operated to evaluate its effectiveness against high turbidity surface water with and without coagulation. The objective was to evaluate the efficacy of the HRF in removing turbidity, total organic carbon (TOC), total coliform and particulate matter. The HRF was operated at filtration rates of ...

Four Benefits of Industrial Water Filtration Systems for Organizations
Industrial facilities and smaller commercial businesses can produce a wide variety of contaminants in their wastewater streams. Industrial water filtration systems can be an integral part of an industrial or commercial process water or tertiary wastewater treatment system application.Below, we listed four benefits of using industrial water filtration systems for organizations.BenefitsReduction of ...

Wichita ASR Project, KS – Bromate Control Case Study
The City of Wichita’s Aquifer Storage Recovery (ASR) Project involves seasonal operation of a UF/disinfection plant to treat storm water from the Little Arkansas River for groundwater recharge. Constituents of concern included atrazine, viruses, turbidity, total organic carbon (TOC), and bromate. Each of these constituents had a potential significant impact on possible treatment processes. ...

Source Water Monitoring Guide for Drinking Water Treatment
The purpose of source water monitoring is to enable drinking water treatment facilities to identify changes in water quality, implement treatment strategies based on the characteristics of the water, optimize the treatment processes, and take preventative actions to protect the source water from intentional and accidental contamination. Unexpected changes in water quality or the presence of ...
