of the mixer, the instructions given in this manual should be thoroughly
understood and followed.
KEEP THE MANUAL IN A READILY ACCESSIBLE LOCATION FOR
FUTURE REFERENCE.
Changes and additions to the original edition of this manual will be
covered by a “CHANGE NOTICE” supplied with the manual. The
change notice will explain any changes made to the product described
in this manual.

SAFETY INFORMATION
WARNING
DO NOT REMOVE VALVE OR DO ANY MAINTENANCE IN THE
PHI VALVE ENCLOSURE OR ON ANY PART OF THE PHI MIXING
SYSTEM UNTIL ELECTRICAL POWER IS TURNED OFF AND
LOCKED OUT FOR BOTH THE COMPRESSOR AND THE VALVE
PANEL. AIR PRESSURE TO CONTROLLER AND ALL PIPING
SHOULD BE AT 0 (ZERO) PSI TO PROCEED.

SYSTEM OPERATION
Simplicity in design, effective mixing, and the low power requirement
makes the PHI 310 an ideal solution for any mixing application found in
a wastewater and water treatment plant.
The key to its effective mixing is achieved by proper sequencing of very
large air bubbles. Each bubble contains 2-4 cubic feet of air and
requires approximately ½ to 1 hp of energy. Depending on the
application the system will generate 2-6 bubbles per minute.

HOW THE PHI SYSTEM WORKS
The air pulse is approximately ½ second in duration and is injected
through the forming plate. The forming plate distributes the air equally
around its circumference creating a large flat bubble mass that rises at
a rate of approximately four feet per second. This rapid rise of the large
bubble mass pulls liquid and solids up behind it as it rises. When the
bubble breaks the surface and exits from the liquid, the water continues
to rise to the surface. A second bubble is released after 10 to 60
seconds which continues the water flow from the bottom to the top of
the tank. When the water reaches the surface, it flows outward. As it
encounters a fixed wall or a virtual wall (formed when flow from multiple
bubbles come together), there is only one way the water can travel, and
that is down. The water flows down the tank and when it reaches the
bottom flows back toward the forming plate. This circular flow is what
creates the effective mixing currents. This can be observed by watching
the underwater video found at www.phiwater.com.
In the video, the red streamers show the actual water flow. This
substantiates Dr. Arnold’s CFD modeling that shows that the energy is
additive and achieves a steady state in approximately 30 minutes

MIXING ZONES
When mixing requires solids to be suspended, as found in wastewater
treatment plants the effective mixing area is 1:1.2 ratio. This means for
each foot of water depth the effective mixing zone is a 1.2’ radius from
the center of the forming plate. Thus a forming plate in 10 feet of water
will have a radius of influence of 12’ (24’ in diameter). The practical
placement of the bubble forming plates is at a 1:1 ratio as shown below:

BUBBLE FORMING PLATE MOUNTING
To mount the stainless steel bubble forming plate on a concrete
surface, two concrete anchors are used as shown in the following
diagram:
For a steel tank there are two ways to install the bubble forming plate:
The first option is to purchase a PHI magnetic mounting kit. These
powerful stainless steel magnets will hold the plate to the bottom of a
flat carbon steel surface. The second option is to weld 1/4” bolts or

all-thread to the tank floor, being careful to match the hole pattern of the
plate (See Addendum 4). If the surface is not flat, then use leveling nuts
to square the plate and then bolt the plate in place (make sure to use all
three holes).

PIPING
The plate connection is a 1” NPT pipe nipple and all piping coming from
PHI controller must be 1” and leak free! Choose the material for the
piping or the tubing/hose that best fits the environment that it will be
used in. It is recommended to use only NSF 61 approved material for
potable water. For corrosive environments use only the material that will
sustain in the environment. PVC piping is not recommended for
compressed air; however, it can be used on the output side of the PHI
controller as the bubble forming plate end is not sealed, so the air in the
pipe is not compressed. (Use CPVC as the higher temperature rating is
required.)
You must use piping or hose that is approved for compressed air (125
psi) from the compressor to the PHI controller. Do not undersize the
pipe. The supply pipe size will increase in size with the number of
controllers connected to it. (Please contact PHI for sizing.) The piping to
the controller must be a minimum of 1” and the same 1” size to the
plate(s).
If two bubble forming plates are connected from one valve, then
the pipe distance from the “T” to each plate must be equal in
length for air balance. Bubble forming plates must be level and
equal height from the tank bottom when in a “T” configuration to
assure an even distribution of air.
