Public vs. Private Water Utilities: PBSCs and PPPs used for financial sustainability
© Aristotle University of Thessaloniki (6/2009)
A public-private partnership (PPP) scheme is a “product providing tool” becoming more and more popular worldwide due to the inability of the public sector to finance a number of projects. In developing countries the implementation of PPPs is crucial especially in the water supply sector. The projects have to do with the reduction of NRW and the provision of better water supply services. Several problems concerning the implementation of PPP and PBSC projects are discussed. The present paper is a review paper discussing a number of key success factors identified for the Public Private Partnerships (PPP) and the Performance Based Service Contracts (PBSC) based in previous studies concerning their successful implementation.

Characteristics of intracellular and extracellular organic components of the Microcystic aeruginosa and their byproducts formation potential during chlorination
© Aristotle University of Thessaloniki (6/2009)
Characteristics of the intracellular organic components (IOCs) and extracellular organic components (EOCs), including dissolved organic carbon (DOC), dissolved organic nitrogenous (DON), algae toxin, B-Cyclocitral, molecular weight distribution and hydrophilic-hydrophobic property, have been investigated. The results indicated the amount of IOCs was 3-10 times higher than that of EOCs.

ECOLOGICAL SANITATION: PRINCIPLES, TECHNOLOGIES AND PROJECT EXAMPLES FOR SUSTAINABLE WASTEWATER AND EXCRETA MANAGEMENT
© IWWG International Waste Working Group (10/2007)
Current conventional approaches to wastewater management and sanitation fall under the category of either waterborne or dry systems. In both cases the system design is based on the premise that excreta is a waste, and that waste should be disposed. It also assumes that the environment can safely assimilate this waste. Unfortunately many years, of experience have shown that such conventional approaches are unable to make a significant impact on the sanitary backlog of nearly half of the worlds population, and even in cases where conventional approaches have succeeded in providing a functioning sanitary system, their long-term sustainability is questionable, as is their appropriateness to address the MDGs.

Lignin wastewater treatment using anaerobic hybrid reactor
© IWWG International Waste Working Group (11/2006)
Several operational problems have been experienced in both suspended growth and biofilm systems, which are widely used for wastewater treatment. In recent years, some researches focusing on hybrid systems have been examined to overcome the problems.

Integrated solid waste management for energy recovery in the island of Crete
© IWWG International Waste Working Group (11/2006)
Crete is an energy-importing region with 100% of energy consumption supplied by imported fuels. In this regard, renewable energy like waste-to-energy is become attractive.
