Can you please write $1-2$ pages on the calculations for a low profile compact air stripper. Please use the picture for reference to the calculaitons. Sizing Calculation for the BREEZE Compact Air Stripper

Project ID: $1$

March $24,2024$

This recommendation is based on a flow rate of $400$ gallons per minute, a pH of $7\mathrm{.}57$ and an influent

water temperature of $68$ degrees $F.$

If the off$-$gas is to be treated, use the calculations for fine bubbble and adjust blower$/$fan pressures

upwards to over come the additional back$-$pressure within the system. Consult AEROMIX for

additional sizing information.

The Air to Water $($AW$)$ ratio for the entire system is based on the requirement to remove the

limiting contaminant. In this case the limiting contaminant is $1,2-$Dichloroethane, which

requires an AW ratio of $395$ for Coarse Bubble, and $250$ for Fine Bubble.

The exact requirement for each contaminant is listed below.

Required Fan Discharge

To determine the fan capacity, flow in GPM is converted to CFM $W_W$ by the formula CFM $W_W=GPM0\mathrm{.}134.$

This result is multiplied by the AW ratio to get the required fan output in SCFM$.$

For Coarse Bubble:

$SCFM=(4000\mathrm{.}134)395=21,123$

$SCFM=(4000\mathrm{.}134)250=13,369$

For Fine Bubble:

Required Tank Size and Chambers

The number and size of the BREEZE tanks depend on the air requirement, the water flow and whether

off gas treatment is required. The BREEZE System handles up to $100$ SCFM per chamber for coarse

bubble and $50$ SCFM for fine bubble. The number of chambers for each system is shown below.

For Coarse Bubble:

For Fine Bubble:

$13,\frac{369}{50}=268$ Total Chambers.

The hydraulic capacity of any BREEZE Tank is $200$ GPM$.$ For a flow of $400$ GPM$,$ a minimum of $2$

tanks are required. Taking into account the AW ratio and the flow through the system, we recommend

$24$ Series $9$ BREEZE Systems for Coarse Bubble, or $30$ Series $9$ BREEZE Systems for Fine Bubble.
