Overview
The need for decentralized, affordable, eco-friendly filters
Centralized treatment seldom reaches rural hamlets, peri-urban fringes, and disaster-affected regions. Decentralized filtration empowers households, schools, and clinics to secure safe water locally.
POSEIDON advances this by using biodegradable alginate beads that bind metal ions with high specificity, minimizing secondary waste and lifetime cost. The system operates with negligible energy, aligning with low-resource contexts and climate-conscious operation.
Households, schools, and clinics need point-of-use protection that works off-grid and near-source.
Biodegradable alginate beads, minimal energy, and modular maintenance prevent secondary pollution.
Translating POSEIDON into a product
POSEIDON is packaged as a cartridge-based filter: plant-derived biopolymer beads with immobilized metal-binding peptides are housed in modular, replaceable units. When capacity is reached, cartridges can be regenerated or swapped—supporting circular use, predictable maintenance, and scalable logistics for schools, villages, and small institutions.
Stakeholders who can accelerate real-world deployment include:
- Corporate social responsibility programs seeking measurable water-impact projects in mining, power, and manufacturing zones.
- Urban and regional water boards piloting biological polishing stages for metal removal at local nodes.
- Rural health missions and NGOs establishing school/clinic drinking-water stations with low OPEX and simple upkeep.
Market at a glance
POSEIDON serves distinct yet intersecting segments where metal contamination and access constraints overlap. The cartridge form factor enables tiered SKUs and local assembly.
| Segment | Primary Need | Adoption Context | POSEIDON Fit | Deployment Example |
|---|---|---|---|---|
| Rural & Tribal Households | Safe water near-source | Low-income; intermittent power | Low-cost cartridges; gravity flow | Village standposts and home units |
| Schools & Health Centers | Child-safe drinking water | Simple upkeep; predictable cost | Replaceable modules; service kits | School filtration corners; clinic inlets |
| Industrial Clients | Metal polishing at outlets | Compliance & CSR reporting | Custom columns; regeneration SOPs | Mining & power-plant outfalls |
| NGOs & Relief Agencies | Light | rapid deployment | Emergency & remote camps | Packable kits; no power required,Disaster-relief water points |
| Global LMIC Context | Affordability & logistics | Local manufacturing preferred | Open design + local bead-making | Regional assembly hubs |
Competitor landscape (snapshot)
Conventional systems deliver general purification but create trade-offs in energy, cost, and waste. POSEIDON’s bio-based approach targets heavy metals at low concentrations while reducing plastic footprints and maintenance complexity. Further during our discussion with the company Digital Paani, we understood how the water filter industry operates and how the market performs. They also mentioned that their other USP was the software they had developed and the technology used to modulate that process and the pipeline of their workflow. They appreciated that our technology is both unique and human-friendly—encompassing both affordability and a positive environmental impact.
| System | Metal Specificity | Energy Use | Secondary Waste | Maintenance | Indicative Cost Note | Notes |
|---|---|---|---|---|---|---|
| Reverse Osmosis | Low–Moderate | High | Brine + plastic membranes | Medium–High | Capex+Opex high | Removes minerals; water wastage |
| Activated Carbon | Low | Low | Spent carbon disposal | Low–Medium | Low–Medium | Great for organics; weak for metals |
| Ion-Exchange Resins | Moderate–High | Low–Medium | Resin + regenerant waste | Medium | Medium–High | Metal capture; chemical handling needed |
| Synthetic Membranes | Moderate | Medium–High | Membrane replacement | Medium–High | Medium–High | Clogging/fouling risks |
| POSEIDON (Bio-beads) | High (target metals) | Low | Compostable beads; minimal plastic | Low | Low–Medium | Regenerable cartridges; low OPEX |
Metal specificity at low concentrations, cartridge regeneration, and low OPEX in decentralized settings.
RO and synthetic membranes increase energy use, brine/plastic waste, and maintenance burden.
