Moringa oleifera Seed Coagulant for Water Purification¶

Ceramic Filtration • Est. CapEx: $0 USD • Lifespan: 3 Years (Replace Element)

Technical Overview¶

A natural, low-cost water purification method using crushed Moringa oleifera seeds as a bio-coagulant. Ideal for rural and developing communities lacking access to chemical coagulants like alum, it reduces turbidity, pathogens, and organic pollutants by simple addition, stirring, and settling.

Key Specifications & Engineering Parameters¶

Parameter	Specification
Category	Ceramic Filtration
Capital Cost (CapEx)	$0 USD
Power / Energy	100% Gravity / Zero Power
Target Scale	Community Scale
Standard Lifespan	3 Years (Replace Element)
Technology Maturity	Commercially Available
Primary Mechanism	Cationic proteins in Moringa seeds (e.g., dimeric proteins of ~13 kDa) neutralize negatively charged suspended particles (clay, silt, microorganisms), causing them to aggregate into larger flocs. These flocs settle by gravity, allowing physical removal of turbidity and attached microbes, with salt extraction (e.g., NaCl) enhancing protein solubility and coagulation efficiency.
