Resin Column Groups for Galvanic Water Treatment – ​​Technical Details and Advantages of Buying Used

Units for Galvanic Water Treatment are highly specialized systems used in water treatment applications, especially in industrial settings, where specific purification operations are required for electroplating plants. These systems are designed to remove heavy metals, salts, and other chemicals from the water used in metal treatment processes, such as chrome plating, galvanizing, and painting.

Purchasing a used resin column assembly can be a profitable choice, especially for those seeking a quality system at a competitive price. Let's take a look at the features, specifications, and advantages of these systems.

Features and Components of the Resin Column Group for Galvanic Water Treatment

• Main function: The resin column assembly is used to treat wastewater from electroplating processes, which often contains heavy metals and other pollutants. The system relies on the use of ion exchange resins that effectively remove pollutants from the water.

• Number of columns: The units generally consist of one or more columns, depending on the required treatment capacity. Each column is filled with an ion exchange resin specific to the type of contaminant to be removed. The resins can be periodically regenerated to extend their life.

• Type of resin used: The ion exchange resins used can be cationic or anionic, depending on the contaminants present in the water. Cationic resins are best suited for removing metal ions such as lead, cadmium, and copper, while anionic resins are useful for treating compounds such as chlorides or sulfates.

• Size and Treatment Capacity: The size and capacity of the column unit depends on the specific model and the required treatment capacity. A column unit can treat several liters of water per minute (L/min), depending on the system's needs. Used units for sale generally have a capacity ranging from 1,000 to 2,000 liters per minute , but it is essential to check the specifications for each individual system.

How the System Works

Electroplating water treatment is done through an ion exchange . The contaminated water passes through columns containing resins, which exchange polluting ions for harmless ones, thus removing the contaminants from the water.

• Water Passage: Contaminated water enters the system, where it flows through columns containing ion exchange resins.
• Removal of contaminants: The resins retain metal ions and other pollutants present in the water, returning purified water.
• Resin regeneration: When resins are saturated with pollutant ions, they must be regenerated. This process involves the use of regeneration solutions, such as acid or salts, which remove the contaminants from the resins, restoring their treatment capacity.

Maintenance and care of the system

As with any industrial system, resin column units require regular maintenance to ensure optimal operation over time. Here are some recommended practices:

• Resin Monitoring: Resins must be monitored periodically to ensure they are not depleted. When the resins are saturated, treatment efficiency decreases and regeneration must be performed.
• Periodic regeneration: Resin regeneration must be performed regularly to prevent degradation of treatment capacity. The type of regenerant and frequency depend on operating conditions.
• Cleaning and checking the system: It is important to clean the columns regularly to avoid blockages or the formation of deposits that could compromise the efficiency of the system.

Sectors of Use

groups with resins for galvanic water treatment are used in various industrial sectors, including:

• Electroplating: Treatment of wastewater from metal plating processes, such as chrome plating and galvanizing.
• Chemical industry: Treatment of water containing heavy metals and other chemicals.
• Industrial wastewater treatment: Used for the treatment of wastewater containing metal contaminants.
• Automotive and aerospace industry: For the treatment of waste water from metal painting and coating processes.

Advantages of Buying a Used Column Group

Buying a used resin column unit offers numerous economic advantages, while maintaining high quality standards:

1. Cost savings: A used unit can be purchased at a fraction of the price of a new one, with similar performance and without sacrificing quality of treatment.
2. Reliability: If properly maintained, a used unit can continue to provide excellent performance for many years.
3. Advanced technology: Used column units from established companies can be equipped with modern, high-performance technologies, which enable highly effective purification.

Safety and Regulatory Compliance

The column groups with resins for galvanic water treatment are designed to comply with safety and environmental regulations. In particular:

• CE Regulations: Unless expressly stated that the machine complies with CE regulations, it is important to verify compliance before purchasing. If not, it can be adapted to European regulations by installing safety devices such as pressure relief valves and protection systems.
• Operator safety: It is important to follow all safety procedures during resin maintenance and regeneration, as the processes may involve the use of aggressive chemicals. Ensure that all operations are performed by qualified personnel.

Price and Negotiability

The prices of used column units with resins for galvanic water treatment vary depending on the model, the age of the system, and its capacity. However, average prices for a used unit range between €1,000 and €2,000 , with the possibility of negotiating a better price based on the unit's condition.

Conclusion

Purchasing a used resin column unit for electroplating water treatment is a cost-effective option for companies looking to save money without sacrificing quality and efficiency. When properly maintained, these systems can provide years of reliable service, representing a solid solution for industrial water treatment. If you're looking for a great deal, take advantage of the opportunity to purchase a quality used unit, which will allow you to achieve excellent results at an affordable cost.
