Numericals on Water Softening — Study Resources & PYQs
Numerical problems involving water softening processes.
- Estimated study time: 75 minutes
Study resources
- Numericals on Zeolite & Lime-Soda Softening (Video) — Curated YouTube search for solved numerical problems on softening capacity and quantity of chemicals required.
- Zeolite & Ion Exchange Process - lectures (Video) — Curated YouTube search - choose an RGPV/AKTU style lecture that also works through softening numericals alongside the theory.
- Water Technology - Lucknow University (B.Tech 1st year lecture notes) (PDF) — Covers the whole unit in one PDF: hardness types, degree of hardness, CaCO3 equivalent, zeolite process, scale and sludge. The main reading for this unit.
- Zeolite & Ion-exchange Process - JECRC lecture notes (PDF) — Dedicated notes on both softening processes with regeneration reactions, residual hardness values, and the formulas used in numericals. Ends with practice questions.
- Hardness of Water by EDTA Method - Lecture 9 (numericals) (Video) — Continuation of the previous lecture with solved numerical problems. Do these along with the video rather than just watching.
- Water and its Treatment - Digitech Education notes (Article) — Handwritten-style notes covering the entire unit topic list including numericals. Note: the download is password-protected via the site's Instagram.
