Why is coagulation needed before filtering?
Very tiny particles pass through filters. Coagulants make them stick together into larger clumps that settle or get caught.

To kill remaining bacteria and viruses and keep the water safe as it travels through pipes.

How to ask a question people can answer
A good thread on the Water Purification Stages saves everyone time. Start with a title that names the exact problem, such as the input you used, the result you expected and the result you got. A title like “Not working” is hard to answer, while a title with the specifics gets replies quickly.
- Say what you tried. List the steps you followed and any settings you changed, so replies do not repeat what you already did.
- Share a small example. A short sample input and the output you saw is worth more than a long description. Remove anything private first.
- Mention your setup. Your device, browser and whether you are on a phone or a computer can explain many odd results.
- One question per thread. Separate topics get clearer answers and are easier to find later with the search box above.
- Come back and reply. If a suggestion worked, say so and upvote it, and if you found the fix yourself, post it for the next person.
