Private Well - Important Customer Information For Installing UltraFiltration
Bladder Tank for Well Water Ultrafiltration Systems
Well and spring water quality can vary due to geological conditions, seasonal changes, or surface influences like heavy rain or snowmelt, which may introduce turbidity or pathogens. To ensure optimal performance of your UrSpring Ultrafiltration system, we strongly recommend installing a membrane expansion tank (bladder tank) downstream of the UrSpring. This tank provides two key benefits:
- Peak Demand Buffering: Stores water to maintain consistent pressure and flow during high-demand periods, preventing system strain.
- Enhanced Membrane Cleaning: When properly pre-pressurized, the bladder tank enables partial backwashing during forward flushing, helping to clean the membrane and extend its lifespan. Important: No backflow preventer should be installed between the UrSpring and the bladder tank for backwashing to function.
Recommended Bladder Tank Sizes
Based on household size, we recommend the following tank capacities:
- 1–2 persons: 40-gallon bladder tank
- 1–4 persons: 80-gallon bladder tank
- 4–6 persons: Two 80-gallon bladder tanks
For households with higher water usage or additional consumers (e.g., irrigation or livestock), contact us for a custom design to handle peak loads.
Sediment-Filter Add-Ons
To protect the ultrafiltration membrane and enhance system performance, consider adding optional pre-filters:
Sediment Filter: A 100 μm filter is standard for most well water systems. For high turbidity or surface influence (e.g., during heavy rain), an automatically flushing filter with a finer mesh (e.g., 1–5 μm) is recommended.
Carbon Block Filter System : Ideal for removing odors, tastes, or organic compounds, especially when paired together with Ultrafiltration. A 10-5 μm sediment filter is advised to prevent clogging of the carbon media.
