Model EF-071 - Struvite Remover



Earth First EF-071 Struvite Remover attacks and removes Struvite which is often a major problem in wastewater treatment plants and concentrated animal feeding operations. Struvite is a hard mineral that is deposited inside pipes, valves, centrifuges and other areas having contact with the wastewater stream. EF-071's environmentally friendly formulation also effectively dissolves Vivianite, Calcium Carbonate and other mineral deposits. Struvite buildup restricts water flow and therefore reduces the operating capability of the plant and eventually results in mechanical failure. Typical remediation is to scrape off the deposits or replace the equipment. The product works quickly and effectively to dissolve Struvite in both on-line and off-line plant application procedures, typically within 24-72 hours based on the thickness of scale accumulation. EF-071 is a mild food grade organic acid that is safe to handle and easy to apply.

  • Heat Exchangers
  • Pumps
  • Valves
  • Centrifuges
  • Or any other High Turbulence Areas within your system


Cooling Towers:

  • For scale removal in Cooling Towers, apply 10 to 1 dilution to feedwater in pan on a drip system.
  • Contact a GAS Representitive for a complete treatment protocol.


  • Contact a GAS Representitive for a complete treatment protocol.

Wastewater Treatment:

  • For Struvite/scale removal in wastewater systems, apply 1 to 1 solution for moderate scale build-up or 2 to 1 solution for heavier build-up.
  • To inhibit build-up, apply product at a rate of 40 to 50 PPM in wastewater systems.
  • 1 lb of EF-071 will remove 1 lb of scale
