tESTING & TREATMENT FOR WATER CORROSIVITY
Water corrosivity refers to the ability of water to degrade or corrode materials, such as metal pipes, plumbing systems and structures, over time. This process not only damages water infrastructure but also leads to contamination of water supplies with dissolved metals such as lead, copper, lithium and iron. Understanding and managing water corrosivity is crucial for maintaining the integrity of industrial, commercial, and residential water systems.
FACTORS AFFECTING WATER CORROSIVITY
| pH Level | Water with a pH less than 7 (acidic) tends to be more corrosive to metals like iron and copper. |
|---|---|
| Alkalinity | Lower alkalinity (bicarbonate ion concentration) reduces the buffering capacity of water, making it more prone to corrosion. |
| Dissolved Oxygen | High dissolved oxygen levels increase the rate of corrosion, particularly in metals like iron and steel. |
| Hardness (Calcium and Magnesium) | Hard water tends to form protective scale, reducing corrosion, while soft water lacks these protective properties. |
| Chloride and Sulfate Ions | High concentrations of chloride and sulfate ions accelerate corrosion, particularly in chloride-sensitive metals like stainless steel. |
| Temperature | Higher temperatures generally accelerate chemical reactions, increasing the rate of corrosion. |
| Microbial Activity | Certain bacteria, such as sulfate-reducing bacteria (SRBs), produce corrosive byproducts that can accelerate localized corrosion. |
| Conductivity | High water conductivity increases the rate of electrochemical reactions, facilitating corrosion. |
| Flow Rate | High flow rates can wear down protective layers on metal surfaces, exposing fresh metal to corrosive water. |
THE TEAM YOU NEED
we specialize in assessing and quantifying water corrosivity and the remaining lifespan of plumbing systems.
CORROSIVITY MONITORING TECHNIQUES
At Water-Genics, we offer advanced corrosivity monitoring solutions to provide real-time data on the state of water systems. We use several techniques to monitor and quantify water corrosivity, allowing us to recommend precise treatments and interventions.
| TECHNIQUE | DESCRIPTION |
|---|---|
| Linear Polarization Resistance (LPR) | This technique measures the corrosion rate by applying a small voltage and monitoring the resulting current. It is widely used due to its accuracy and real-time data capability. |
| Corrosion Coupons | Metal samples exposed to the water environment for a fixed period. Weight loss measurements help calculate corrosion rates. |
| Electrochemical Impedance Spectroscopy (EIS) | A non-invasive technique that uses alternating current to analyze corrosion kinetics and surface layer properties. |
| Remote Corrosion Sensors | These sensors provide continuous, real-time data on corrosion activity and environmental conditions, offering early warning of potential issues. |
| Microbial Corrosion Monitoring | Specific sensors can detect the presence of corrosion-inducing bacteria, allowing early intervention. |
OUR SPECIALIZED SERVICES
We can identify potential safety concerns in drinking water, determine their source, and offer tailored corrosion mitigation solutions.
WATER TREATMENT & CORROSION MITIGATION
Addressing water corrosivity involves implementing appropriate water treatment methods. At Water-Genics, our team is skilled in diagnosing corrosion issues and recommending effective treatments tailored to specific water systems.
| WATER TREATMENT | DESCRIPTION |
|---|---|
| pH Adjustment |
Adding alkaline substances like sodium bicarbonate or calcium carbonate to increase the pH of the water. |
| Corrosion Inhibitors | Introducing chemicals (e.g., phosphates or silicates) that form protective layers on metal surfaces. |
| Cathodic Protection | Installing sacrificial anodes or impressed current systems to protect metal surfaces from corrosion. |
| Scaling Control |
Adjusting water hardness to encourage the formation of protective scale that shields the metal from further corrosion. |
| Disinfection and Biological Control | Controlling microbial corrosion through UV disinfection or chemical treatments to reduce bacterial activity. |
