During the severe storms on April 17, 2013, around 5 p.m., a lightning strike hit a transformer near the intersection of 77th Street and Roberts Road in Bridgeview. The image was taken by someone for me, and it shows the aftermath of the event. Transformer fire in Bridgeview. Buffalo Grove firefighters were called to 414 Manchester Court just before 3 p.m. due to a reported structure fire. It appears that a lightning strike caused a fire on the building’s exterior, which then extended slightly into the second floor. Here are some photos from the scene.

From Larry Shapiro:
These images provide a clear view of how quickly emergency crews responded and the extent of the damage caused by the storm. Lightning strikes can be unpredictable and dangerous, often leading to fires or power outages. It's reassuring to see how well-prepared the local fire department was in handling this situation.
Water Treatment Resin are specialized materials used in water purification processes, particularly in ion exchange systems. These resins are typically composed of small, porous beads that can exchange ions with ions in the water that passes through them. There are two main types of ion exchange resins: cation exchange resins and anion exchange resins.
Types of ion exchange resin:
Strong Acid Cation (SAC) Resins: These resins contain sulfonic acid groups and are used to remove positively charged ions (cations) such as calcium (Ca²âº), magnesium (Mg²âº), and other heavy metals. SAC resins are commonly used in water softening applications.
Weak Acid Cation (WAC) Resins: These resins contain carboxylic acid groups and are effective at removing cations, particularly in applications where water has a high alkalinity.
Strong Base Anion (SBA) Resins: These resins contain quaternary ammonium groups and are used to remove negatively charged ions (anions) such as sulfate (SOâ‚„²â»), nitrate (NO₃â»), and chloride (Clâ»). SBA resins are often used in deionization processes.
Weak Base Anion (WBA) Resins: These resins contain tertiary amine groups and are effective at removing anions from solutions with lower pH levels.
Cation exchange resins are commonly used to replace calcium and magnesium ions in hard water with sodium or potassium ions, thus preventing scale buildup in pipes and appliances.
Both cation and anion exchange resins are used together in mixed bed or separate bed configurations to remove all ionic species from water, producing highly purified water. This is crucial in applications such as laboratory water, pharmaceuticals, and microelectronics manufacturing.
This process involves using both types of resins to remove dissolved salts from water. It's used in boiler feedwater treatment and other industrial processes where mineral-free water is required.
Specialized resins can be used to target specific contaminants, such as heavy metals, nitrates, or arsenic, from drinking water and wastewater.
Water treatment resins require periodic regeneration to restore their ion exchange capacity. Regeneration involves flushing the resin with a concentrated solution of the ions that the resin initially releases. For example:
SAC resins are regenerated with a salt (sodium chloride) solution.
SBA resins are regenerated with a caustic (sodium hydroxide) solution.
Regular maintenance and proper regeneration are essential to ensure the longevity and efficiency of the resins.
Conclusion
Water treatment resins are a critical component of many water purification systems, providing efficient removal of a variety of contaminants. Their effectiveness and versatility make them suitable for a wide range of applications, from residential water softening to industrial demineralization. Understanding the types and functions of these resins can help in selecting the right one for specific water treatment needs.
