The article presents the results of scientific research on operation pumping equipment at reclamation stations. In stations, more and attention is being paid to measures maintain reliability efficiency units reduce negative impact factors various origins. One most significant affecting service life increased vibration unit. According analysis failures stations in Uzbekistan for 2010-2021, than ...

Air emissions from waste treatment plants often consist of a combination of Volatile Organic Compounds (VOCs) and odors. Hydrogen sulfide is one of the major odorous gases present in the waste emissions coming from municipal wastewater treatment facilities. Hydrogen sulfide (H2S) is odorous, highly toxic and flammable. Exposure to lower concentrations can result in eye irritation, a sore throat...

A nonlinear mathematical model for the optimal operation of a parallel pumping station group was established with objective minimizing costs considering target quantity water extraction and flow unevenness between units each as constraints. The original is decomposed into several sub-models single multi-objective optimization lifting capacity pump coordinating variable. This constructed solved ...

In Algeria, there are many isolated sites which are not yet connected to the conventional electrical grid and face severe problems of water for domestic consumption and irrigation purposes. There are some photovoltaic water pumping system (PVWPS) which are situated in remote areas. Due to the high cost of setting up and maintaining a large number of PVWPS, we present in this project a methodolo...

Previous terrorist attacks, system failures and natural disasters have revealed the problems that many States face in preparing for national civil contingencies. The diversity of critical infrastructures and the interconnections between different systems makes it difficult for planners to ‘think of everything’. For example, the loss of power distribution networks can disrupt rail and road trans...

The optimal modes of the existing compensating devices under operating conditions were determined. Minimum power and energy losses taken as optimality criteria. unconstrained optimization problem was considered, i.e., finding absolute minimum. When solving to find mode operation “SUV OKOVA” network, a relative minimum found since system constraints has nonlinear form. conditional in terms react...

Increases in the energy costs of irrigation water pumping facilities puts economic sustainability recent investments modernization farms at risk. To address this problem, it is essential to apply renewable technologies for production electricity, and photovoltaic particularly attractive due its lower cost technological advances. The aim research develop a mathematical techno-economic dispatch m...
