Can the flow rate be adjusted for use with a sand filter?
The UV-Tube is designed to work effectively at a flow rate of up to 5 liters per minute. Anything less than that is fine. If water has high turbidity, then it is possible that it has high absorbance and therefore the UV Tube will not work as effectively. In areas where the water has high absorbance, a sand filter will reduce the absorbance and increase the effectiveness of the UV Tube. Sand filters, when maintained properly, are effective in improving the taste and appearance of the water, as well as removing some pathogens. However, sand filters cannot remove viruses. A UV Tube installed after a sand filter would ensure that all pathogens are eliminated. How much does a UV Tube system cost? The cost of the UV-Tube depends on the locally available materials and the specific design adapted to a region. The cost can range from $60-$150 (USD). What are the maintenance costs of a UV-Tube? UV Tubes are designed to require minimal maintenance. If properly installed, a UV Tube should not need
