A design method for thickeners and clarifiers known as the batch flux curve technique was developed over 20 years ago but still is not well known in design and operating circles An informal survey of major clarifier and thickener manufacturers found that none of the firms surveyed use this method for sizing and maximizing operating conditions.

Clarifier FAQ S

The sludge thickening tank will also act as a buffer receiving sludge when the clarifier is ready to dump the sludge and feeding the filter press as it is ready to receive the sludge The clarifier and the filter press may not always be ready to work at the same time and the sludge holding tank can be used to accumulate the sludge.

WasteWater System Centrifugal Sludge Thickening Process

Sludge that comes out from clarifier or sedimentation tanks can have varying solid contents depending on efficiency and control of the whole wastewater operation Generally the higher the liquid percentage the less desirable it is because wet sludge is harder to handle and when it comes to subsequent wastewater processes like drying and digestion it will mean more energy consumption.
