    Gravity thickeners are normally sized to handle the maximum seasonal or monthly sludge yield anticipated. Peak daily sludge production often requires storage in the thickener or other sludge processing units. Low liquid overflow rates result in maladours from septicity of the thickener contents. A common remedy is to feed dilution water
