7,800 Gallon MgOH Magnesium Hydroxide Storage Tank. Click for larger image.A typical Magnesium Hydroxide mixed storage tank is approximately 2,500 gallons, where multiple tanks are typically used to achieve a chemical usage/delivery cost  optimums.  

Attached is a typical 4,000 gallon poly storage tank that presents an alternative low cost magnesium hydroxide storage tank option for your consideration.  The basis of the design makes the following assumptions:

Design Basis:

  1. Maximum Specific Gravity = 1.60
  2. Maximum Viscosity = 2,500 centipoise
  3. 7,800 Gallon Poly Storage Tank: Diameter = 120", SS = 159", Dome Top, OAH Tank= 175"; Norwesco.  OAH Mixer= 179"
  4. 5,600 Gallon Poly Storage Tank: Diameter = 119", SS = 117", Dome Top, OAH Tank = 137"; CHEM-TAINER.  OAH Mixer = 141".
  5. A vertical-on-tank-centerline mounting arrangement is used.
  6. Non-standard In-tank anti-swirl baffles are required per mixer manufacturers recommendations. 
  7. Optional Angular offset mounting, without the need for anti-swirl baffles available upon request requiring design review.
  8. Dual impellers to quickly overcome inherent dewatering & stratification.   
  9. No in-tank anti-swirl baffles are required, unless the polymer is less than 1,500 centipoise. 
  10. 316D Stainless Steel mixer wetted parts with 316 Stainless Steel hardware.
  11. 230/460 Volt Power source.
  12. Mixer support bridge supplied by others.

Three Primary Equipment Design Options:
   1. All non-stainless components coated with two-part corrosion resistant epoxy paint.
   2.  A Non-Painted Mixer available in two configurations.  In lieu of investing cost into paint & its related labor, a marginal cost adder is invested into all corrosion resistant materials that is suitable for 95% plus of all mixing applications which includes stainless couplings & exposed hardware:
     Option A - Only the motor is provided with that manufacturers commercial grade paint.
     Option B - Use an all stainless steel wash down duty motor.

This mixers advantages are significant:

  1. Lowest continuous energy cost using both lower horsepower's & speeds. Maximum high flow capability impellers combined with lower horsepower, higher torque mixers maximize the available utility of the design.
  2. After investing in both paint & its labor, it is inevitable that surface damage during installation will occur.  In time, exposed surfaces due to flaking & peeling is also inevitable causing sites for corrosion.  Chalking & discoloration is also common.  A corrosion resistant non-painted mixer is a better overall long term investment.  
  3. Time & manpower costs are always an issue.  Contractors can be costly, lifting equipment is expensive, internal work teams must be scheduled & prioritized causing costly system delays & reacting to emergencies is always an expensive proposition.  Although installations typically include on-site erection equipment & labor force, downtime is another mater.  Maintenance & operators prefer designs that feature light weight one-man gearboxes as future servicing will be required.  In many cases, the removable motor assembly divides the assembly into two light weight components.  Being able to handle the servicing yourself gives autonomy within a system resulting in immeasurable benefits.  
  4. Model AQPX is a pedestal mounted mixer option locating the agitator shaft coupling above mounting surface which allows you to hang the shaft & impeller in place.  The lightweight one-man gearbox & motor component assemblies can then be easily removed for servicing.
  5. These are NOT throw-away-mixers.  The have a projected life of 11+ years {24 hour per day service life}.  These mixers are designed to be dusted off, repaired or rebuilt, and put right back into service.    
  6. Easy access lube points and oil servicing located above the mixers mounting surface.  External viewable Site glass to easily observe oil levels. 
  7. Equipped with flexible motor coupling to absorb inherent shock loads to protect the overall service life our super quiet gearing.  The motor coupling allows for quick removable, retrofit (new motor replacement) & reinstallation. 
  8. Engineering Mixer Specification.
