Study on the Sludge Capitalization as a Fertilizer for Ornamental Garden Plants

Abstract

The paper aimed to demonstrate that the sludge from wastewater treatment plants can be used efficiently as a fertilizer in horticulture because in the near future the storage of this sludge will become a problem. For this reason, we approached the study on the recovery of the sludge from the wastewater treatment plant of Brăila as fertilizer in the crops of ornamental garden plants that are not intended for consumption. The correct management of the sludge from wastewater treatment plants may bring a positive contribution to the vegetation development rate. The main objective of the sludge treatment is the capitalization and the decrease of negative impact on the environment.
