Marchis DM, Nistor MC, Badulescu
The necessity for the management of the sludge from sewage has emerged as a result of rehabilitation of existing wastewater treatment plants and investments in construction of new wastewater treatment plants. Therefore, a rapid increase in the volume of sludge produced is expected. From the perspective of the operators sludge is produced incessantly and without being stopped and the raw material varies both during the day and seasonally, with the weather and the attitude of industrial units towards discharging the wastewater into public sewerage. For now, the public display little concern regarding sewage sludge but perceptions and concerns can change easy due to lack of information and even an hostility to the use of sludge in agriculture which is still the best practical option in terms of the environment and that involves lowest capital and operating costs. This paper comes in support of the idea of using sludge from wastewater in agriculture, after carrying out experimental studies on both the composition and quality of the slurry to correspond the legislative provisions, namely the Order of the Ministry of Environment and Water and Ministry of Agriculture no. 344/2004 approving the technical norms on environmental protection and in particular of the soil when sewage sludge is used in agriculture.
