Innovative Sludge Management Techniques for Developing Nations

Sustainable and Innovative Solutions for Sewage Sludge Management

Sludge produced by municipal wastewater treatment plants (WWTPs) amounts to only a few percent by volume of the processed wastewater, but its handling accounts for up to 50% of total operating costs. Moreover, the need to achieve a sustainable sludge management strategy has become of great concern. It follows that as conventional and more traditional options, such as land spreading for agricult...

An innovative solution for managing waterworks sludge: Developing an alum sludge-based multi-stage constructed wetland system for wastewater treatment

Waterworks sludge continues to be an inescapable by-product of the potable water treatment process. Accordingly, final disposal of the sludge remains one of the most significant pressing problems for the potable water treatment industry. The possibility of reusing the sludge as a main substrate in a novel constructed wetland system was investigated in this study. Results show that significant p...

Technology and innovative options related to sludge management

The treatment and disposal of sewage sludge is an expensive and environmentally sensitive problem. It is also a growing problem world-wide since sludge production will continue to increase as new sewage treatment works are built and environmental quality standards become more stringent. With some traditional disposal routes coming under pressure, and others such as sea disposal having been phas...

Innovative Imputation Techniques Designed for the Agricultural Resource Management Survey

The Agricultural Resource Management Survey (ARMS) is a high dimensional, complex economic survey which suffers from item non-response. Here, we introduce methods of varying complexity for imputation in this survey. The methods include stratified mean imputation, the approximate Bayesian bootstrap, and non-iterative and iterative sequential regression. The iterative sequential regression is a f...
