Quick Answer
For a group of five on a hiking trip, a recommended daily flow rate is between 1 and 2 liters per person, which translates to 5-10 liters per day for the entire group. This allows for drinking water, cooking, and hygiene needs. A flow rate of at least 1 liter per hour is recommended.
Setting the Right Expectations
When it comes to water filtration systems, it’s essential to understand the concept of flow rate. This refers to the volume of water that can be filtered per unit of time, typically measured in liters per hour (LPH). For a group of five, a flow rate of at least 1 LPH is recommended to ensure everyone has enough drinking water throughout the day.
Choosing the Right Filter
When selecting a water gravity bag filter, consider the following factors: filter pore size, flow rate, and maintenance requirements. A filter with a pore size of 0.1 microns or smaller can effectively remove bacteria, viruses, and parasites from water. For a group of five, a filter with a flow rate of 1-2 LPH should be sufficient to meet daily water needs.
Tips for Optimizing Flow Rate
To maximize flow rate, make sure to use a filter with a pre-filter or pre-treatment stage. This can help remove larger debris and sediment, reducing the load on the main filter and increasing flow rate. Additionally, use a water container with a wide mouth and a filter system that is specifically designed for gravity-fed flow. This will help to reduce flow restrictions and optimize the performance of the filter.
