Biopolymer-Based Green Nanomaterial Adsorbents¶
Membranes & Advanced Filtration • Est. CapEx: Low-cost / Locally fabricated
Technical Overview¶
An emerging class of eco-friendly water treatment materials synthesized from bio-waste and biopolymers, as reviewed in Springer. These nanomaterials target heavy metals, organic dyes, and microbial contaminants in decentralized and rural treatment contexts.
Key Specifications & Engineering Parameters¶
| Parameter | Specification |
|---|---|
| Category | Membranes & Advanced Filtration |
| Capital Cost | Low-cost / Locally fabricated |
| Primary Mechanism | Biopolymers such as alginate, chitosan, or cellulose are doped with metal-oxide nanoparticles (e.g., ZnO, TiO2) or graphene oxide to form composite hydrogels or membranes. The biopolymer matrix adsorbs contaminants via chelation and electrostatic interactions, while embedded nanoparticles provide photocatalytic degradation under UV or visible light. |
| Target Scale | Household / Village Cluster |
| Standard Lifespan | 10 - 20 Years |
