Chapter 1: Techniques

Corosex: A Reliable Solution for Neutralizing Acidity in Water Treatment

1.1 Introduction

Corosex, a product of Clack Corporation, is a highly effective media used in water filtration systems to neutralize acidic water. It is made from processed magnesia, a naturally occurring mineral known for its ability to react with acidic compounds and raise the pH of water.

1.2 How Corosex Works

Corosex works by reacting with acidic compounds like hydrogen ions (H+) in water. This reaction neutralizes the acidity, raising the pH level to a more balanced range. The reaction can be summarized as follows:

MgO (Corosex) + 2H+ → Mg2+ + H2O

In this reaction, magnesium oxide (MgO), the primary component of Corosex, reacts with hydrogen ions (H+) to form magnesium ions (Mg2+) and water (H2O). The formation of water effectively removes the acidic hydrogen ions, neutralizing the acidity.

1.3 Application Techniques

Corosex can be applied in various ways depending on the specific water treatment system and the desired level of pH adjustment.

• Batch Treatment: In this method, Corosex is added directly to a tank or container of water and allowed to react with the acidic compounds. After a specific contact time, the water is typically drained and replaced with fresh water.
• Continuous Flow Systems: Corosex is often used in continuous flow systems, such as water filtration systems. In this application, the water is continuously passed through a bed of Corosex media, allowing for continuous pH adjustment.
• In-Line Treatment: Corosex can be incorporated into in-line water treatment systems, where it is used to treat water directly before it is used. This is often done in applications where it is important to ensure that the water is treated as it is being used.

1.4 Factors to Consider

Several factors need to be considered when using Corosex for water treatment, including:

• Water Chemistry: The acidity and mineral content of the water will determine the amount of Corosex needed for effective pH adjustment.
• Flow Rate: The flow rate of water through the treatment system will influence the contact time between the water and the Corosex media.
• Temperature: The temperature of the water can affect the reaction rate between Corosex and acidic compounds.
• Target pH: The desired pH level for the treated water should be determined based on the specific application.

1.5 Conclusion

Corosex is a versatile and effective media for neutralizing acidity in water treatment. Proper application techniques and consideration of relevant factors ensure optimal performance and effectiveness of the treatment process.
