Wastewater treatment - Dewatering | Britannica

Wastewater treatment - Wastewater treatment - Dewatering: Digested sewage sludge is usually dewatered before disposal. Dewatered sludge still contains a significant amount of water—often as much as 70 percent—but, even with that moisture content, sludge no longer behaves as a liquid and can be handled as a solid material. Sludge-drying beds provide the simplest method of dewatering.

There are no disadvantages to water purification -- it's essential for healthy drinking water -- but it has some shortcomings because it may not remove every possible contaminant from drinking water.

Water purification

The latest filters constructed have a fine sand layer, 600 mm thick, supported on a 500 mm gravel layer. They are washed by using air to first loosen the sand and then water, at an up wash rate of 32 m/h, to wash away all the collected dirt. Filters are covered to exclude light to less than 25 lux to prevent algal growth on the filters.
