Environmental Pollution Control Engineering By C S Rao Apr 2026

Rao taught a generation of Indian engineers that pollution is not an abstract environmental problem; it is an engineering problem . And every engineering problem has a solution—usually involving a settling tank, a chimney height calculation, and the courage to speak truth to power (or at least to the factory owner).

In the pantheon of Indian technical literature, most books serve a fleeting purpose: help you pass an exam, then gather dust. But every few decades, a book transcends its syllabus. C. S. Rao’s Environmental Pollution Control Engineering is one such quiet titan. Environmental Pollution Control Engineering By C S Rao

If you see a tattered, blue-covered copy of Rao on a senior engineer’s desk, know this: That person doesn't just know how to control pollution. They know how to calculate it. Rao taught a generation of Indian engineers that

Rao is , not modern. His strength is fundamentals. In an era of "black box" technology, Rao forces you to understand the physics of settling tanks and the chemistry of flue gas desulfurization. Once you know Rao, you can walk onto any old factory floor in Asia or Africa and troubleshoot a malfunctioning clarifier without a laptop. A Personal Anecdote (The Unofficial Legend) There is a running joke in Indian engineering colleges: "If you can solve all the problems at the end of each chapter in Rao, you don't need a semester, just a calculator." But every few decades, a book transcends its syllabus
