## How do you size a UV water purification system?

Flow rate guidelines for a Whole-Home UV Water Sterilizer System:

- 1 Bathroom: 6 gallons per minute flow rate.
- 2 Bathrooms: 9 gallons per minute flow rate.
- 3 Bathrooms: 12 gallons per minute flow rate.
- 4 Bathrooms: 15 gallons per minute flow rate.
- 5 Bathrooms: 18 gallons per minute flow rate.

## What is the ideal flow rate in water filters?

The accepted standard for most applications is 30 mJ/cm2*. A slower flow rate will result in a higher UV dose. The longer the chamber and the longer the water stays in contact with the UV lamp, the higher the dose.

## What flow rate do I need?

The average household needs 100 to 120 gallons per person per day, and a flow rate of about 6 to 12 gallons per minute.

## Does UV light purify water?

Disinfecting your water with Ultraviolet light is exceptionally simple, effective and environmentally safe. UV systems destroy 99.99% of harmful microorganisms without adding chemicals or changing your water’s taste or odor.

## How do I choose a UV sterilizer?

As a general rule, the longer the lamp, the greater amount of UV light the water will receive because it will be exposed to the UV source for a longer period of time. Choose a uv sterilizer with a 3 or 5 inch (7.6 or 12.7 cm) diameter body.

## Does GPM affect water pressure?

Shower heads are measured by flowâ€”that is, the number of gallons they deliver per minute (GPM). Flow is affected by water pressure, measured in pounds per square inch (psi). The greater the pressure pushing water through pipes and shower heads, the greater the volume of water forced out.

## What is the average gallons per minute for a well?

It depends on the source of the well water. It should be a minimum of 600 gallons within a two-hour period, or about 5 gallons per minute for 2 hours.

## How many GPM can go through a 2 inch pipe?

2-inch pipe: 850 gallons per minute.

## What is normal water flow rate?

A toilet will normally use about 2-3 gallons per minute (gpm), a shower from 1.5 to 3.0 gpm, a bathroom or kitchen faucet from 2-3 gpm, a dishwasher from 2-4 gpm, and a washing machine from 3-5 gpm.

## How do you calculate water flow rate?

Calculate the GPM Flow Rate Multiply the measured quantity of water by 6 to calculate the flow rate in gallons per minute (GPM). In our example, 1/2 gallon collected in 10 seconds multiplied by 6 (to equal one minute) equals 3 gallons. Therefore, the flow rate is 3 GPM.

## Is 4 gallons per minute a good well?

The Water Well Board and the New Hampshire Water Well Association, a group of private professionals associated with the well water industry, both recommend a flow rate of 4 gallons per minute for a 4 hour period. That’s equivalent to 960 gallons of water flowing steadily for 4 hours.

## What is a good shower flow rate?

Standard shower heads use 2.5 gpm, but to earn the WaterSense label, a product must use no more than 2 gpm and still meet strict performance requirements. The EPA estimates that the average family could save 2,900 gallons of water per year by installing a WaterSense-labeled shower head.
