Branch
designs and builds custom fabricated mass transfer equipment for gas
absorption and removal.
The
most common types of aeration devices we provide are:
Packed Columns for either absorbing
or stripping gases.
Tray
Column.
In
water service applications, air will saturate incoming water as it
moves vertically downward through the columns. Volatile gases trapped
in the water are released into the air as the water contacts the high
surface packing media.
Units can be used with air provided from one of several sources
including:
Blowers
Compressed gas
Natural Draft Designs
The basic principle remains the same in
all the installations made.
Our countercurrent absorption (aeration) and stripping columns are the
most common design used because of the high efficiencies
achieved.
CAPACITIES
From small units up to 4 MM GPD (15120 m3/d) have been built in single
module construction. Multiple modules have been provided
for larger applications.
MATERIALS OF CONSTRUCTION
Since Branch Environmental custom fabricates
individual columns as required, virtually any material of construction
can be used for fabrication.
Towers have been built in all of the
following:
• Fiberglass - using FDA approved resins
• Polypropylene
• Stainless Steel
• Aluminum and coated/lined metal construction.
