Treatment for AQUA-CLEAR® AE Acid Enhancer

Description AQUA-CLEAR® AE liquid blend of acids and acid enhancers is formulated to control bacterial slime contamination due to the presence of iron-related and sulfate-reducing bacteria.
Applications/Functions
  • Can remove the biomass matrix caused by bacterial fouling
  • Can reduce sulfur taste and odor in water
  • Can clean up well screens, pumps and distribution system
  • Can restore well productivity and reduce power and maintenance costs
  • AQUA-CLEAR AE acid enhancer can be used in combination with AQUA-CLEAR® MGA modified granular acid to remove more difficult scale and incrustation
Advantages
  • Safe to use on all plastics, rubber, and metals
  • Cost-effective, efficient extended life treatment
  • Helps improve water quality and renews well production rate
  • Helps mitigate corrosion and equipment failure
  • Helps reduce pumping costs
Typical Properties
  • Appearance - Light amber colored liquid
  • Specific gravity - 1.08
  • pH of the solution - 1.1
Recommended
Treatment
To treat bacteria fouling
  • Record initial well water pH
  • The preferred application method is to apply a solution of AQUA-CLEAR AE acid enhancer into the screened interval through a tremie pipe.
  • Mix AQUA-CLEAR AE acid enhancer with water at 12 ounces (one soft drink can) per gallon of water or 94 ml per liter of water and apply directly into the screened interval with a tremie pipe. When utilizing this method, calculate the volume of water in the screened area and double the calculated volume to account for the water in the gravel pack and formation interface.
Note: The above concentration of AQUA-CLEAR AE acid enhancer is recommended for a complete reconditioning of an existing well.
  • Calculation for volume in well:
    • Gallons per foot = (diameter, inches)2 x 0.042
    • Liter per meter = (diameter, millimeters)2 x 0.0008
  • Displace solution into the well screen and formation, then surge, swab, agitate or jet well through screen and gravel pack for 20-30 minutes.
  • Allow to stand in well for up to two hours and then repeat activity approximately every two hours for a period of 24 hours.
  • Pump well to waste until well water pH is within 0.5 of original well pH.
Note: Wastewater can be neutralized by adding soda ash or lime
  • Chlorinate well and reconnect to the water distribution system.
Caution: Never mix chlorine and AQUA-CLEAR AE acid enhancer in well.
  • If necessary, AQUA-CLEAR AE acid enhancer may be poured directly into well as per treatment table, but results will not be as good as if applied via a tremie pipe.

Notes:

  • Occasionally for heavily encrusted wells, it is desirable to brush or scrape the casing and screen, then pump or airlift the debris to waste prior to treating with acid.
  • The following charts recommend a concentration of
    AQUA-CLEAR AE acid enhancer that is suitable for a typical maintenance treatment of an existing well.

Note:
The concentrations of AQUA-CLEAR AE acid enhancer shown in the previous tables do not take into account the 100% excess volume required to compensate for the water present in the formation interface and gravel pack. The previous tables only account for the product concentration required for the volume of water occupying a 10 foot or 10 meter section of a given size of the screen.

For other diameters:

  • Gallons per foot = (diameter, inches)2 x 0.042
  • Liter per meter = (diameter, millimeters)2 x 0.0008
  • Gallons of AQUA-CLEAR AE acid enhancer = (gallons per foot x 8.34) x 0.0026
  • Liters of AQUA-CLEAR AE acid enhancer = (liters per meter) x 0.0241
  • Double the calculated volume in order to take into account the water present in the gravel pack and formation interface.

Treating Severe bio-fouling and scaling

  • AQUA-CLEAR AE acid enhancer is used as an acid enhancer when mixed in the well with AQUA-CLEAR MGAacid
  • One gallon of AQUA-CLEAR AE acid enhancer to every 10 pounds of AQUA-CLEAR MGA acid
  • 3.8 liters of AQUA-CLEAR AE acid enhancer to every 4.5 kilograms of AQUA-CLEAR MGA acid
Safety
  • Use recognized standard practices for handling corrosive and acidic materials (refer to Material Safety Data Sheet)
  • Avoid skin and eye contact – flush with water
  • Do not ingest and avoid prolonged inhalation
  • When disposing of waste fluid make sure to comply with all federal, state and local regulations as applicable.
Packaging AQUA-CLEAR AE acid enhancer is packaged in 5-gal (19-liter) full opening plastic pails with a snap on top and flex spout.
