A 500L seawater desalination device that meets the standards for domestic water use

1.Product Description

"300L seawater desalination" refers to the process of treating seawater (or brackish water) with a relatively high salt content into fresh water that meets the standards for domestic and industrial use through specific technical means, with a final output of 300 liters. The core is to remove sodium chloride (the main component of table salt) and other impurities (such as magnesium ions, calcium ions, microorganisms, etc.) from seawater, and reduce the salinity of water (generally, the salinity of desalinated fresh water should be less than 500mg/L, and that of domestic drinking water should be less than 1000mg/L).

2.Examples of typical scenarios

1.Outdoor emergency response: When camping on an island, carry a small RO seawater desalination machine. After connecting it to seawater and powering it with the vehicle's power supply, it can produce about 300 liters of fresh water in about 1-2 hours, meeting the needs of multiple people for drinking and cooking.

2.Household backup: In case of a typhoon in coastal areas causing a disruption in fresh water supply, a simple solar distillation device (such as a large plastic bucket or a glass lid) can be used to collect 300 liters of fresh water continuously for 1-2 days for basic living needs.

4.Key points to note

1.Pretreatment: Regardless of the technology used, solid impurities such as sediment and plankton in seawater should be filtered out first (preliminary filtration can be carried out using gauze or filter screens) to prevent equipment blockage or impact on desalination efficiency.

2.Post-treatment: If the water is for drinking, it is recommended that the desalinated water be filtered through an activated carbon filter (to remove odors) or boiled (to kill residual microorganisms) to ensure drinking water safety.

3.Energy consumption matching: For small-scale RO methods, attention should be paid to the power supply capacity (for example, the battery needs to be able to run the equipment for 1-2 hours), while for solar distillation methods, the device should be set up in an area with sufficient sunlight.
