Dewatered Sludge Treatment
Introducing additives into dewatered sludge can improve its physical and chemical properties. Requirements differ depending on the disposal site, so treatment systems should be able to adapt to various methods of disposal. Dewatered sludges treated in seepex systems are more adaptable because of the consistent nature of both the dry solids content and their shear resistance.
For agricultural use, dewatered sludge is normally treated with quick lime. Because of the exothermal reaction of quick lime with water, moisture content is reduced and sludge structure enhanced. Nutrient enrichment of the sludge with the addition of quick lime makes dewatered sludge more acceptable for agricultural applications.
Gentle treatment and consistency are of critical importance to the structure of sludge. Then, optimal reaction between additive and sludge can be assured with complete sterilization and lasting neutralization.
