Protocol Overview
The intent of the protocol is to determine;
1. How much scale each product will dissolve
2. When the product is concentrated by mineral saturation, evaporation and evaporation
to dryness, whether or not insoluble materials are observed, as in suspended solids or
the growth and or adherence of crystallization.

WaterSolv Curative AG
Assumptions
WaterSolv Curative dissolves more scale than any of the other products, 9.2% more than Blast,
and 60% more than the next nearest competitor. Neither Blast nor WaterSolv Curative contain
ingredients that would tend to buildup in the environment requiring the need for additional
remediation products or increased treatment rates.
However, the demand for salt remediation in soil and water distribution lines could diminish
where the HCl is no longer required, where the demand shifts to stabilizing soluble salts. This is
the purpose of WaterSolv Ag, versus WaterSolv Curative.
Pricing wise, the value of WaterSolv curative could be considered 9% greater than Blast by
efficacy from the results of this report. We do know however that the reversion products of
Urea & HCl products do not form the stable cations that are realized by the use of WaterSolv
products. Such cation stabilization results in 20% increase in growth rate, size and duration with
12% less water and nutrients, which may show both short and long term benefits.
Note: Watersolv Curative readily dissolved the precipitate and crystals of DeSal and URA-PHOS 26-0.
