Model LBA - Liquid Biofouling Control Agent
LBA is a liquid, bio-fouling agent used for the removal of bio-fouling from the well screen area. LBA is certified by NSF International. LBA is certified to NSF/ANSI Standard 60, Drinking Water Treatment Chemicals - Health Effects.
LBA cleans casings, screens, and all other components of the well that are affected by bio-fouling or iron bacteria.
- LBA acts as a chelating agent, allowing more dissolved minerals to be pumped to waste, therefore preventing re-depositing of the minerals
- LBA has the ability to penetrate and disperse debris layers
- LBA is also used to debris fouling of environmental monitoring and recovery wells, oil/water separators, air strippers, and other types of equipment used in groundwater remediation
- LBA is non-corrosive and nontoxic
- Test well pH before starting treatment. Disconnect distribution system.
- Calculate quantity of LBA by using the Dosage Table. Normal dosage is 5-7% solution. If gravel pack is present, the volume of water in it should be accounted for as part of the total well volume (typical porosity of gravel pack is 30-40%).
- Add LBA directly into the well through the casing. Agitate the well for 12-48 hours by surging, jetting, or circulating the water. Compressed air may be used to agitate the well.
- Upon completing agitation, DPA can be added to the well if mineral encrustation is present.
- Pump the well until water is clean and free of acid to within 0.5 units of original pH. Reinstall pumping equipment.
- Chlorinate the well with a shock treatment of sodium hypochlorite at 500 to 1,000 ppm. Pump the well until clear of chlorine.
- 5 gallon pail, 27 or 28 per pallet, 15 gallon pail, 8 per pallet, o r 55 gallon drum, 4 per pallet. All pallets are plastic-wrapped.
