The Importance of Treating Drinking Water

Clean water is essential for life on the planet, and while the Earth is made up of more than 70% water, the portion of water that is suitable for consumption is quite limited. Water originating from natural sources such as rivers, lakes, aquifers, and even manmade reservoirs can contain dirt, pathogens, and minerals that cause scale. Additionally, acidic waters can cause corrosion and leaching of heavy metals, such as lead and copper, from transport and household pipes. Overall, improper treatment of these impurities can create issues ranging from public health emergencies to colossal expenses combatting water distribution problems.

Lime Slaking Systems & Upgrades

Over time, equipment at drinking water treatment facilities may need updated or replaced due to normal wear and tear or for the integration of new technologies. Carmeuse Systems supplies advanced equipment solutions for lime storage, handling, and slaking.

Our expert engineers can design the right solution to keep your water treatment operation running smoothly, from new lime handling systems and slakers, to retrofits and upgrades for your existing equipment. For additional information related to our lime handling expertise, visit the website.

Lime vs Caustic Soda for Water Treatment

When comparing the use of lime products to the use of caustic soda (sodium hydroxide) in water treatment, there are a number of considerations to take into account.

Lime is often the most cost-effective product when compared to caustic soda for use in water treatment plants. Quicklime has a stronger neutralizing capacity per dry ton than caustic soda, and it is more efficient at heavy metals precipitation.

Slaked lime is also considered a safer alternative for use in water treatment processes such as acid neutralization, pH adjustment and metals removal, when compared to caustic soda. While safety measures are required when handling lime, caustic soda is more corrosive and is extremely hazardous in terms of exposure to the skin and eyes, with the potential to cause chemical burns.
