Reactivator

Reactivation: A Vital Step in Environmental & Water Treatment

In the world of environmental and water treatment, reactivation plays a crucial role in ensuring optimal performance and extending the lifespan of key components. It involves restoring the effectiveness of materials that have become less efficient due to use and time, like the removal of contaminants from water.

Reactivation processes are tailored to the specific material and application, but generally involve one or more of the following:

• Chemical Regeneration: Utilizing chemicals to restore the original properties of the material. For example, in water softening, a resin can be reactivated by backwashing with a brine solution.
• Physical Regeneration: Employing physical methods like heat, pressure, or agitation to rejuvenate the material. A good example is the regeneration of activated carbon by heating it to high temperatures, burning off adsorbed contaminants.
• Biological Regeneration: Utilizing biological processes to enhance the material's effectiveness. In biological wastewater treatment, bacteria are used to break down organic matter, and their activity can be enhanced through periodic aeration.

Reactivation is essential for several reasons:

• Extending Equipment Life: Reactivation can significantly prolong the lifespan of treatment components, reducing the need for costly replacements.
• Maintaining Treatment Efficiency: By restoring the material's effectiveness, reactivation ensures that the treatment process continues to meet required standards.
• Cost Savings: Reactivation is typically less expensive than purchasing new materials, leading to significant financial benefits.

Solids Contact Clarifiers by Graver Co.: A Case Study

Solids contact clarifiers are essential components in water treatment, used to remove suspended solids from the water stream. Graver Co., a leading provider of water treatment solutions, designs and manufactures a wide range of these clarifiers.

Reactivation plays a vital role in the operation of Graver's solids contact clarifiers. These systems typically employ a combination of physical and chemical reactivation techniques:

• Backwashing: The clarifier is periodically backwashed to remove accumulated solids from the filter bed. This is a physical reactivation process that ensures efficient water flow and contaminant removal.
• Chemical Cleaning: To remove organic matter and other contaminants that can build up over time, the clarifier can be chemically cleaned. This is done by introducing a cleaning solution that dissolves the contaminants.

By implementing these reactivation methods, Graver Co. ensures that their solids contact clarifiers maintain optimal performance and provide a long service life.

Conclusion

Reactivation is an indispensable part of environmental and water treatment, contributing to the efficient operation, longevity, and cost-effectiveness of treatment systems. Whether it's restoring the activity of a resin or cleaning a solids contact clarifier, reactivation plays a crucial role in ensuring clean and safe water for all.
