This introduction covers The Journey from Source to Tap within Water Treatment for GCSE Chemistry. Revise Water Treatment in Using Resources for GCSE Chemistry with 23 exam-style questions and 15 flashcards. This topic shows up very often in GCSE exams, so students should be able to explain it clearly, not just recognise the term. It is section 1 of 14 in this topic. Use this introduction to connect the idea to the wider topic before moving on to questions and flashcards.
💧 The Journey from Source to Tap
Water treatment plants are like giant cleaning factories! Raw water enters dirty and contaminated, goes through multiple cleaning stages (screening, settling, filtering, disinfecting), and comes out pure and safe. Just like a car wash has different stages — rinse, soap, scrub, final rinse — water treatment has screening, sedimentation, filtration, and chlorination!
