Superfine water cleaning system with “net zero” power consumption as a renewable power source

Abstract

Paper presented at the 8th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Mauritius, 11-13 July, 2011.

A rational nature management advanced by the United Nations Industrial Development Organization UNIDO gives impetus to proliferation of all that is associated with the «green industry» concept, namely ecology, power effectiveness, environmental protection against industrial pollution, in particular, protection of the water reserves and their rational usage [1]. The need in the fastest realization of the like developments is connected with not only purely ecological issues but, also, with more and more common man-made catastrophes causing lengthy breaks of the power and heat supply to utilities, small enterprises, medical institutions, all types of transport, etc. The like situation contributes to development of independent power micro systems (IPMs) on the basis of many concepts (from Stirling engines and solar batteries to micro turbines and fuel cells [2-7]), on one hand, and the most environmentally friendly and power saving independent water cleaning systems [8-12], on the other hand The paper includes results of: - development of a superfine water cleaning system where all the power required for the system’s operating is generated directly in the process of cleaning; - researches over designed and built main parts of the system – lab devices: • the power saving five-step cleaning system with the exit water quality meeting requirements to water utilized at fish-breeding and with production of the gaseous fuel in amount sufficient to generate the electric and heat power, when IPMs of the electric efficiency not below 28% and the total efficiency not less 80% are applied; • the micro gas turbine engine (μGTE) with the electric efficiency of (28±1)% and the total efficiency over 80%.
