Quick Answer
A secondary filter is often needed for spring water systems to remove particulate matter, sediment, and bacteria that may not be addressed by the primary filter.
Primary Filter Limitations
When it comes to spring water systems, a primary filter is typically a sediment filter with a pore size of 1-5 microns to remove larger particles and sediment. However, this may not be enough to remove smaller particles, bacteria, and other contaminants that can still be present in the water. For example, some spring water systems may have a high level of particulate matter due to the geology of the surrounding area.
Secondary Filter Options
A secondary filter, on the other hand, can provide a higher level of filtration to remove smaller particles, bacteria, and other contaminants. Some common secondary filter options include:
- Activated carbon filters to remove chlorine, taste, and odor
- Ultraviolet (UV) filters to kill bacteria and viruses
- Ceramic filters with a pore size of 0.2-0.01 microns to remove even smaller particles
- Reverse osmosis (RO) filters to remove dissolved solids and contaminants
Filter Selection and Maintenance
When selecting a secondary filter for a spring water system, it’s essential to consider the specific needs of your system and the level of filtration required. This may involve testing the water to determine the level of contaminants present. It’s also crucial to maintain the filters regularly to ensure they continue to function effectively. This may involve replacing the filters at recommended intervals and cleaning or replacing the filter housings as needed.
