Chlorine vs WaterSOLV BC
When rehabilitating water wells, selecting the right chemical strategy is critical for long-term performance, asset protection, and predictable outcomes. Two commonly discussed options are chlorine disinfection and HCT’s WaterSOLV™ BC. Here, we explain the differences, limitations, and why WaterSOLV™ BC is often the better choice for engineered well rehabilitation.
Why Chlorine Isn’t Enough
Chlorine has a long history as a disinfectant in municipal and pool water treatment. However, in the context of water well rehabilitation:
-
It is not designed or labeled to penetrate biofilms or polysaccharide matrices that form inside well screens, gravel packs, and near-wellbore formation.
-
It primarily acts on free-floating bacteria, not entrenched microbial films.
-
It can be highly corrosive to steel and metal well components at the concentrations needed for aggressive disinfection — often requiring extensive post-treatment flushing to mitigate corrosion by-products.
For these reasons, even when used as directed, chlorine often delivers short-term microbial reduction but fails to improve long-term well hydraulics or biofilm-associated flow loss.
What Makes WaterSOLV BC Different?
WaterSOLV™ BC is a peroxide-based, engineered remediation chemistry formulated specifically for well systems. It is not a disinfectant, but rather a bioremediation and scale breakdown agent developed to address the structural causes of well decline.
Key Functional Benefits
1. Biofilm and Polysaccharide Penetration
WaterSOLV™ BC is formulated to penetrate and disrupt biofilm matrices (polysaccharide and microbial sheeting) that trap iron, sulfate products, and fine sediments — barriers that chlorine cannot effectively degrade.
2. Microbial Impact Beyond Surface Kill
Rather than merely killing free bacteria, WaterSOLV™ BC targets biologically active layers and facilitates breakdown of organic deposits that restrict flow.
3. Detoxifies Soluble Toxins
In addition to microbial effects, WaterSOLV™ BC sequesters soluble salts such as sodium and chloride and converts them into forms that are less harmful and more hydratable.
4. Biodegrades to Oxygen and Water
After performing its function, the chemistry degrades into dissolved oxygen and water — a process HCT calls continuous chemical aerification — which supports aerobic conditions and reduces anoxic issues.
5. Non-Corrosive When Used Properly
Unlike aggressive disinfectants or acids, WaterSOLV™ BC is engineered to be non-corrosive to common well materials when applied according to specification.


Practical Impacts for Wells
Enhanced Hydraulic Recovery
WaterSOLV™ BC helps restore flow capacity more effectively than chlorine because it addresses the root causes of decline — biofilms and inorganic blockages — rather than simply disinfecting. This often results in measurable improvements in specific capacity and reduced rehabilitation frequency.
Longer Performance Duration
By disrupting entrenched deposits and improving water chemistry, wells treated with WaterSOLV™ BC tend to stay cleaner longer than wells treated only with chlorine.
Safer Infrastructure Impact
Engineered application protocols minimize corrosion risk and protect pumps, casings, and screens.
Chlorine is useful for disinfection but is limited and potentially corrosive when misapplied in well rehabilitation. WaterSOLV™ BC represents a more advanced, engineered chemistry that:
-
Penetrates and breaks down biofilms and polysaccharide films
-
Detoxifies harmful salts and metals
-
Biodegrades to dissolved oxygen and water
-
Supports longer-lasting hydraulic performance
For both engineers preparing bid specifications and well owners seeking durable solutions, WaterSOLV™ BC delivers a more comprehensive and sustainable approach to water well remediation.
