TL;DR: These natural coagulants produce a 'low risk' water; however, additional disinfection or boiling should be practised during localised outbreaks/epidemics of enteric infections.
Abstract: Seeds 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 coagulant, produced a substantial improvement in its aesthetic and microbiological quality (turbidity 0.3-1.5 NTU, heterotrophic bacteria 5-20 cfu ml(-1) and fecal coliforms 5-10 MPN 100 ml(-1)). The method appears suitable for home water treatment in rural areas of developing countries. These natural coagulants produce a 'low risk' water; however, additional disinfection or boiling should be practised during localised outbreaks/epidemics of enteric infections.

TL;DR: In this paper, the suitability for use in paints, soaps and detergents etc., the fatty oil from Strychnos potatorum seed is separated, and the total fatty acids arc found to be 60.4% with almost equal quantities of saturated and unsaturated fatty acids.
Abstract: To determine the suitability for use in paints, soaps and detergents etc., the fatty oil from Strychnos potatorum seed is separated. Seed oil obtained by extraction through petroleum ether has a sufficiently high (20.8%) unsaponifiable matter. Total fatty acids arc found to be 60.4% with almost equal quantities of saturated and unsaturated fatty acids. Spectroscopic studies indicate linoleic acid (31.94%) and linolenic acid (8.18%) among the total of fatty acids. Physico-chemical characteristics of the oil and presence of specific natural organic substances are also investigated.

TL;DR: In this article, a study was conducted to investigate the possibility of removing fluoride from water using low cost adsorbents such as Acacia Catechu, Cuminum cyminum, Coens vettriverodies, Eletaria cardamomum, Phyllanthus embilica, Strychnos potatorum and Tamarindus indica.
