With the rapid expansion of cities due to population growth and urbanization, conventional centralized wastewater collection treatment systems are slowly becoming a burden; expensive maintenance is required for aging plants piping infrastructure, cost expanding capacity cover demand from growth, new regulations tighter control over certain pollutants such as micropollutants. As an alternative t...

Thermal energy counts for a large part of the total consumption. To reduce fossil fuel consumption heat and cold generation, different low temperature sources have been considered. Water networks considered as amount water flow through it. measure thermal potential system, this paper provides method in unsteady state to determine systems made buried pipes. The model has applied raw supply syste...

background central dialysate fluid delivery systems (cdds) are used by dialysis centers in japan, and although these systems are effective at delivering dialysate, they have a complex piping network with numerous sites where contamination can develop. in japan, cleaning disinfectants have been clinically evaluated based on endotoxin levels and bacterial counts, but there have been no published ...

An ultrasonic guided wave system for pipe inspection is proposed. Using guided wave experience to date on a variety of different tubing problems, feasibility experiments have already been conducted on piping under insulation in both a laboratory and chemical processing facility field environment. Several guided wave techniques are introduced, one using a broad banded variable angle beam transdu...

AUTHORS 3 The Centralized Renewable Energy System (CRES) at Nebraska Innovation Campus (NIC) is a heat-exchanger system that utilizes reclaimed, non-drinkable water from the nearby water treatment plant to heat and cool a projected 1.675 million square feet of office and lab space. A greenhouse gas emissions inventory was estimated for the CRES operating at full build-out of the campus in 2035,...

The joint general model of reliability and availability of complex technical systems in variable operation conditions linking a semi-markov modeling of the system operation processes with a multi-state approach to system reliability and availability analysis and linear programming considered in the paper Part 1 are applied in maritime industry to reliability, risk and availability optimization ...
