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 ...

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 ...

Efficacy of an appropriate point-of-use water treatment intervention for low-income communities in India utilizing
Moringa oleifera , sari-cloth filtration and solar UV disinfectionThis study investigated the efficacy of a POU water treatment system featuring sari-cloth filtration and/or Moringa oleifera coagulation as pre-treatments for solar disinfection (SODIS). Surface water from a peri-urban slum in Chennai, India, was treated and analysed for turbidity, organic content via chemical oxygen demand (COD) and microbiological quality via most probable number (MPN) ...

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. ...
