In this lecture of *Engineering Chemistry**, we study the **Zeolite Method of Hardness Removal**, one of the most important **water softening techniques* used in domestic and industrial water treatment.
This video explains **what the zeolite method is**, **how hardness is removed**, the **chemical reactions involved**, and the **regeneration of zeolite**, all in a simple and exam-oriented manner.
📌 *Topics Covered in This Lecture:*
– What is Hardness of Water?
– Temporary & Permanent Hardness (Quick Recap)
– What is Zeolite?
– Principle of Zeolite Method
– Construction & Working of Zeolite Softener
– Chemical Reactions Involved:
• Removal of Calcium & Magnesium Salts
• Exchange of Na⁺ ions with Ca²⁺ / Mg²⁺ ions
– Regeneration of Zeolite using NaCl
– Advantages of Zeolite Method
– Disadvantages / Limitations
– Comparison with Lime Soda Process
– Applications in Water Treatment Plants
– Important Exam Points
