Inhoudsopgave

• Groundwater to tap water• Surface water to tap water • Of sea (dune) water to tap water• Purification locations• Purification of Wastewater• Purification of drinking water

From groundwater to tap water

• Easier to clean • Natural purification ~ Pumped up ~ Air ~ Filtered ~ Aerations ~ Filtered ~ Stored

Surface water to tap water

• Water is dirtier• More comprehensive and more expensive ~ Pumped up ~ Reservoir ~ Purification location ~ Microsleves ~ Iron particles ~ Flakes filters ~ Complete cleaning ~ Stored

Of sea (dune) water to tap water

• Surface water• Dune purification process ~ Pre purification ~ Hydrocarbons ~ Oxygen ~ Filtered ~ Stored

Purification location

• Negen locaties. ~ Berenplaat ~ Kralingen ~ Baanhoek ~ Braakman ~ Ouddorp ~ Haamstede ~ Huijbergen ~ Halsteren ~ Ossendrecht

Purtification of wastewater

• Sewage water purification installation ~ Sand catch ~ First sedimentation tank ~ Fat scrapers ~ Aeration tank ~ Biological purification ~ Second sedimentation tank ~ Surface water ~ No drinking water

Purtification of drinking water

• Ground and surface water• No drinking water
