Moringa Saline Extract for Microplastic Coagulation¶

BioSand & Media Filters • Est. CapEx: $6 USD • Lifespan: 7–15 Years

Technical Overview¶

An optimized saline extract from Moringa seeds designed to remove microplastics from low-turbidity drinking water via in-line coagulation followed by sand filtration. Developed as a biodegradable, home-replicable alternative to aluminum sulfate for small communities and rural properties.

Key Specifications & Engineering Parameters¶

Parameter	Specification
Category	BioSand & Media Filters
Capital Cost (CapEx)	$6 USD
Power / Energy	100% Gravity / Zero Power
Target Scale	Community Scale
Standard Lifespan	7–15 Years
Technology Maturity	Prototype
Primary Mechanism	A simple salt (NaCl) solution extracts cationic coagulant proteins from Moringa seeds. When added to water, these proteins neutralize the negative surface charge of microplastics and other colloids, causing particle destabilization and aggregation into larger flocs. In an in-line filtration configuration, these flocs are captured directly by a downstream sand filter without requiring large sedimentation basins.
