Land Disposal of Sludges. This is one of the lower cost alternatives for final sludge disposal. It is practised for two reasons: the need to dispose of the sludge (itself also a residue) and the opportunity to use the contents (organic matter, nitrogen and phosphorus) as fertilizer. Sludge disposal options can be selected by: Evaluating relevant information Narrowing the list of candidate options Identifying options / SELECTING THE BEST SYSTEM Sludge management must meet the prime function of relia- bility as well as satisfy the following conditions: Must be legally acceptable.
The ultimate disposal of water treatment sludge entails two techniques: Landfilling; Land application Landfilling. Landfills may be on public land such as a municipality owned landfill, or on private land. Landfill operators commonly require 15 to 30 % sludge (solids). Disposal of sludge to landfill is perceived by the EC as being the final resort in waste management. The disposal of Sludge to Land Agriculture UK legislation governing the use of sludge in agriculture has been formulated from the provisions contained in the EC birective 86//EEC on 'The Use of Sewage Sludge in Agriculture'.
Sludge disposal is part of what wastewater professionals do, but public opinion demands that sludge be treated to higher and higher levels, driving sludge treatment technology ever higher, as well. This book is an excellent source of current technical information for the practicing engineer on all aspects of sludge treatment and disposal. For various sludge this rate may vary from a low of for activated sludge to a high of 6 to 11 for the best digested primary sludge. The moisture content in the sludge cake also varies with the type of sludge, from 80 to 84% for raw activated sludge to 60 to 68% for well-digested primary sludge.

Wastewater treatment - Wastewater treatment - Sludge treatment and disposal: The residue that accumulates in sewage treatment plants is called sludge (or biosolids).
Sewage sludge is the solid, semisolid, or slurry residual material that is produced as a by-product of wastewater treatment processes.
This residue is commonly classified as primary and secondary sludge.

Primary sludge is from 3 to 6 percent solids. Treatment objectives are reduction of the sludge and volume, rendering it suitable for ultimate disposal. and disposal of municipal sewage sludge. Although the Clean Water Act had required since that EPA develop technical standards for sludge use and disposal, the amendments required that these standards, when promulgated, be implemented through permits.

Sludge Barging Sludge barging or ocean disposal is one of the means of final disposal of sludge that has been practiced by some cities. There is little theory involved in this method of treatment.
Raw, precipitated, digested, or filtered sludge solids are pumped into a waiting barge and transported to a suitable site from the shore, where it is.

effluent and a concentrated stream of solids in liquid, called sludge. The sludge is treated as required for utilization or disposal, and additional treatment of effluent may be needed to accommodate specific water reuse opportunities. The practice of municipal wastewater treatment evolved primarily to accommodate dis-charge.
Sludge treatment is focused on reducing sludge weight and volume to reduce disposal costs, and on reducing potential health risks of disposal options. Water removal is the primary means of weight and volume reduction, while pathogen destruction is frequently accomplished through heating during thermophilic digestion, composting, or incineration.
Initiate rulemaking to change the Part Sludge Rule (promulgated under the authority of the Clean Water Act at 40 C.F.R. §) to eliminate land application as an acceptable practice for sludge disposal. Implement mandatory pollution prevention strategies to prevent hazardous waste from entering the sewer in the first place.
This paper examines the techniques available for selecting the optimum methods of sludge treatment and management depending on local conditions and circumstances. Recent information on sludge production and quality in different countries is reviewed and the methods available for sludge treatment, disposal or re-use are compared.

The remainder of this chapter is divided into four sections. Section describes the source in terms of a multimedia disposal evaluation of the quantity and quality of a sludge.
Section outlines available sludge disposal/reuse options. While sewage sludge is usually treated using a standard plan of action, it is extremely important to factor in aspects like the origin of the sewage, the treatment process used to reduce the sewage to sludge, as well as the possible byproducts that can be retrieved from it for further use before choosing a sludge treatment plan.

urrent sludge regulations limit sludge disposal alterna-tives based on the treatment level provided, pathogen removal, and metals content. At the same time, practical disposal options for sludge involve some form of reuse of the product, whether by direct land application, stabilization, composting, or pelletizing.

To better understand its properties, it is nec-essary to review how it is formed. Generally, it is the solid resi-due recovered from the wastewater stream of the pulping and papermaking process (Fig.
