KATADYN Rapidyn
Utilizes ceramic micropores to block sand, suspended solids, bacteria, and protozoa in water, filtering by gravity without the need for electricity.
View Rapidyn Product InformationIn the event of a disaster, water outage, or supply chain disruption, an ideal water source may not be available. Water may be turbid, pose microbiological risks, or only brackish water or seawater may be accessible. We have compiled four principles of drinking water treatment, representative products, and real-world examples, and included emergency food, to help users establish their disaster preparedness and relief strategy based on on-site conditions.
No single water treatment method covers all situations. Before choosing a product, understand the on-site conditions based on the water source, contamination risk, power supply, and scale of use.
During severe disasters, drinking water may only be obtainable from less than ideal sources. Among the available sources, prioritize water with a relatively lower risk of contamination, away from oil spills and discharge sources, and then treat it according to the product's capabilities. General disaster preparedness products cannot be assumed to remove oil, pesticides, heavy metals, industrial wastewater, or unknown chemical contaminants; if such contamination is clearly suspected, seek an alternative water source or use confirmed appropriate professional treatment equipment.
The following products address different problems. After understanding the principles and limitations, select based on the water source and on-site conditions. If necessary, different technologies can be used in combination.
Utilizes ceramic micropores to block sand, suspended solids, bacteria, and protozoa in water, filtering by gravity without the need for electricity.
Suitable for: Natural freshwater, water outage backup, households, and temporary centers.
Main limitations: Does not remove salt from seawater, and unknown chemical contaminants should not be assumed to be removed.
Add a fixed dosage to the specified amount of water and wait for the product's prescribed reaction time to treat microbiological risks in clear water.
Suitable for: Disaster kits, drinking water disinfection, water storage, and lightweight backup.
Main limitations: Turbid water must be filtered first, and used according to dosage, water temperature, and reaction time.
Uses UV-C ultraviolet light to treat bacteria, viruses, and protozoa in clear water, powered by two CR123 batteries, suitable for personal and household battery-powered backup.
Suitable for: Clear water sources, personal drinking water, and disaster kit configuration.
Main limitations: Does not remove sand, salt, or chemicals; turbid water will affect treatment effectiveness.
Uses reverse osmosis membranes to treat freshwater, brackish water, or seawater, integrating desalination and community water supply into one portable system.
Suitable for: Fire and rescue, evacuation centers, isolated islands, and emergency water supply for large groups.
Main limitations: Equipment selection depends on water source, water production needs, power supply, and operating conditions.
The actual treatment process depends on the water source. The following is a simple guide to understanding the relationship between each technology, which does not mean all water sources can be treated with the same steps.
Water and food need to be planned together. NRG-5 packages emergency energy into easily countable, quick-to-distribute, long-term storage units.
When kitchens, fuel, refrigeration, and normal distribution are temporarily unavailable, emergency food must be ready for immediate consumption and manageable by number of people and days.
From disaster drills in Taiwan, community water resource relief, to mobile water desalination after hurricanes, these cases illustrate the role of different equipment in real-world scenarios.
Demonstrates temporary drinking water backup at disaster sites through gravity filtration that requires no electricity and can be quickly set up.
