Tridel SA, a public corporation, is a modern waste-to-energy plant in Lausanne, Switzerland. It provides both electrical and ther mal energy, totaling about 60 MW. It uses an oscillating firebed. The water used is collected mostly from roofs and paved areas and all waste water conforms to strict standards.

Heavy metals, including mercuryare extracted and sent by rail for recycling. A unique feature is that much of the waste arrives by rail, through a purpose-built 4 km tunnel; as the plant is built about m higher than the lake, this avoids the pollution from numerous trucks per day climbing the steep hill.

Economically, it is viable.

Waste management concepts between countries or regions. This section presents some of the most general, widely- used concepts. The waste hierarchy refers to the "3 Rs" reduce, reuse and recycle, which classify waste management strategies according to their desirability in terms of waste minimization.

The waste hierarchy rem ains the cornerstone of most waste minimization strategies. The aim of the waste hierarchy is to extract the maximum practical benefits from products and to generate the minimum amount of waste.

Extended producer responsibility Extended Producer Responsibility EPR is a strategy designed to promote the integration of all costs associated with products throughout their life cycle including end-of-life disposal costs into the market price of the product.

Extended producer responsibility is meant to impose accountability over the entire lifecycle of products and packaging introduced to the market. Polluter pays principle The Polluter Pays Principle is a principle where the polluting party pays for the impact caused to the natural environment.

With respect to waste management, this generally refers to the requirement for a waste generator to pay for appropriate disposal of the waste.

The Outlook for the Future Urban wastewater management is at a critical juncture in the United States and elsewhere. Methods must again change in response to urban development, population growth, and diminishing natural resources. Based on information in recent literature, current research focuses, and trends in the engineering and regulatory community, three aspects of wastewater management are becoming increasingly important now and will continue to be important in the foreseeable future development of wastewater management.

The three aspects are decentralized wastewater management DWMwastewater reclamation and reuse, and heightened attention to wet-weather flow WWF management.

Currently, consideration of these three aspects in wastewater management planning is improving the functionality of wastewater systems and creating sustainable alternatives to the traditional centralized SSSs.

The reduction in recent years of federal grant money for the construction of wastewater collection and treatment systems required municipalities to search for cost-effective wastewater management alternatives.

In addition, federal legislation e. The requirement that municipal and industrial discharges identify cost-effective wastewater management solutions has curtailed the sometimes blind selection of centralized SSSs for newly urbanizing areas.

And as stated earlier, since World War II newly urbanizing areas have been constructed with lower density than the historical urban areas for which centralized sewer systems were originally designed.

The applicability of centralized management concepts in these less-densely populated urbanizing areas is questionable. The factors of cost-effectiveness and appropriateness have contributed to the development of alternative wastewater management methods including DWM technologies.

Decentralized wastewater management DWM is defined as the collection, treatment, and reuse of wastewater at or near its source of generation.

A significant improvement in the newer decentralized technologies compared to the decentralized privy vault-cesspool system of the nineteenth century is the ability to integrate seamlessly and effectively with water-carriage waste removal.

From the public's perspective, the primary deterrent to implementation of alternative wastewater management technologies has been the fear of a life-style change.

Most individuals desire wastewater management to be unobtrusive, convenient, and not to require significant maintenance efforts on their part.

The newer decentralized technologies have been developed to integrate easily with traditional plumbing fixtures and do not require a significant life-style adjustment.

Essentially, the core components of DWM are the same as centralized collection and treatment systems, but the applied technologies are different. Water carriage is still prevalent, but the wastewater is treated on site or near the site and not transported to a central treatment facility.MODELING AND OPTIMIZATION OF WASTEWATER TREATMENT PROCESS WITH A DATA-DRIVEN APPROACH by Xiupeng Wei An Abstract Of a thesis submitted in partial fulfillment of the.
