Water Treatment Processes
Step 1: COAGULATION- The chemical Alum is added via ducts to help bacteria and small solid particles stick together.
Step 2:CLARIFICATION and FLOATATION – 4-5 hour process where another chemical Polly is added. Mechanical settling basins called clarifiers use gravity to separate out solid particles and remove colour. Finer particles fall on the bottom. This waste material called ‘splurge’ drops into pipes underneath and is collected into tankers. This waste is recycled and used to cover landfills.
Step 3:FILTRATION-Most of the remaining particles are removed as water passes through filters. There are more than 4600 mushroom filters at Winneke.
Step 4: DISINFECTION – The chemical chlorine is added to kill any disease causing bacteria. The amount of chlorine added varies. According to our research, less than one milligram per litre is used.
Step 5: FLUORIDATION – Fluoride is added to the water in small amounts. Fluoride helps prevent tooth decay and MUST be added to our water.
Step 6: pH CORRECTION
