    ENERGY FENCELINE The energy “fenceline” is the scope of operations where the energy improvement goals will be focused and implemented. It is important to think about which operations or areas of the facility have the most outdated equipment, where the energy use is highest, and how expensive it would be to upgrade.

In optimization, a process is regarded as dynamic when it can be described as a well-defined sequence of steps in time or space. Dynamic processes can be either discrete or continuous. Cascades, which are systems characterized by sequential arrangement of stages, are examples of dynamic discrete processes.

Vigneswaran has been working on water and wastewater treatment and reuse related research since During the last twenty years, he has made significant contributions in physico-chemical water treatment related processes such as filtration, flocculation, membrane-filtration and adsorption.

Water and wastewater treatment plants are energy-intensive and account for up to 35 percent of municipal energy consumption.

Particularly pumps and aeration consumea significant portion of energy in water and wastewater plants and should therefore be a special focus. In many cases water and wastewater treatment. Wastewater Heat Exchanger: Energy and Performance Efficient Wastewater Treatment through Heat Recovery.

Warm process water can be used to heat cold fresh water. This helps to optimize the temperatures of the water streams and reduce the energy demand of the wastewater treatment. As an example, the water allocation network optimization approach [59] developed in in industrial processes, has been updated with water reuse and regeneration loops [60], adapted to energy.

They also have the capa­ bility to produce a fuel, biogas (a combination of methane and carbon dioxide), through anaer­ obic digestion of sewage sludge.

A secondary treatment plant may use as. Water and wastewater treatment process optimization reduces the occurrence of problems, protects the environment, ensures regulatory compliance, and saves you money. During the first stage of process optimization, we’ll conduct a thorough evaluation of the process parameters and the external elements that affect the process.

Heuristic optimization models with varying degree of complexity have been widely applied for resolving water resources optimization and allocation problems. Nevertheless, there still exist uncertainties about finding a generally consistent and trustworthy method that can find solutions, which are really close to the global optimum in all Cited by: 1.
