33 guidesWater Treatment
Filtration, coagulation and the unit processes that make water potable.
27 guidesWater
Sources, chemistry and the physical properties behind every process.
16 guidesWater Analysis
Sampling, testing and reading the parameters that define quality.
13 guidesDisinfection
Chlorination, UV and ozone at the final barrier.
9 guidesSoftener
Removing hardness with ion exchange and lime–soda.
6 guidesDesalination
Reverse osmosis and thermal routes to fresh water.
7 guidesCorrosion

From raw water to the tap, in six stages
Every plant is a sequence of barriers. Follow the flow — each stage links to the guides that explain it.
-
01
Intake & Screening
Raw water enters; bar screens and grit channels remove debris.
-
02
Coagulation
Coagulants destabilise fine particles into settleable floc.
-
03
Sedimentation
Floc settles out under gravity in clarifiers.
-
04
Filtration
Rapid sand and media beds polish the remaining turbidity.
-
05
Disinfection
Chlorine, UV or ozone inactivate the remaining pathogens.
-
06
Distribution
Treated water is pumped to storage and the network.
