4,000 Gallon Polymer or
Poly-Electrolyte Day Tank Storage Mixing System:
 A
typical Polymer or Polyelectrolyte mixing day or storage tanks typically range
in size from 200 gallons to 1,500 gallons, dependent upon the plants
requirements. For these size day tanks, 350 RPM mixers are quite common
and may prove to be a more economical solution. Multiple tanks can also be used to increase the daily
capacity or to achieve a chemical usage cost optimum.
Attached is a typical
4,000 gallon storage tank constructed of a polymeric material that presents an alternative low cost
polymer or polyeletrolyte storage or day tank option for your consideration. The basis of the
design makes the following assumptions:
- Maximum Specific
Gravity = 1.05
- Viscosity Range =
1,500 to 2,500 centipoise
- A standard 4,000
gallon poly storage tank, supplied by others.
- A
vertical-on-tank-centerline mounting arrangement is used
- No in-tank anti-swirl
baffles are required, unless the polymer is less than 1,500 centipoise.
- 316D/316 Stainless
Steel mixer wetted parts.
- 230/460 Volt Power
source.
- Mixer support bridge supplied by others.
The advantages are
significant:
- Lower horsepower 3/4.
- Engineering Mixer
Specification
- Hydrofoil in
combination with lower mixer speed, creates lower fluid shear, which
maximizes polymer chemical efficiency.
Complete design for 4000 gallon Polymer or Poly-Electrolyte
Day Tank or Storage
mixing application. Includes engineering specifications, complete mixer pricing,
tank drawing, mixer mounting orientation for waste water treatment systems.
