Ensuring of Reliability and Power Saving When Designing the Facilities for Wastewater Transporting

SUMMARY

Main propositions of methods of the designing of facilities for wastewater transporting, a collector – aeration station system as an example, at increased discharge of wastewater are considered. The consistency of substantiation of the decision ensuring that the system will guarantee reliable transporting and reduction of operation costs is presented. The numerical evaluation is limited with probabilistic [probability of no-failure operation P(t), intensity of failures λ and repairs μ] and parametric [output Q(t) and power consumption W(t)] indices of the system. The methods of calculation developed make it possible to substantiate technical decisions ensuring the reliability and power saving when reconstructing the facilities for wastewater transporting with due regard for requirements for human environment protection.

Key words
