This study aims to investigate the feasibility of using a feedwater heaters system with coal-fired power plant. Furthermore, influence evaluation different coal consumption on plants in terms output and thermal efficiency improvements. As well, this focuses effect heaters' numbers which caused highest exergy destruction plants. For values consumption, parametric was conducted determine The resu...

Inferential sensing is a method which can be used to evaluate the parameters of a physical system based on a set of measurements related to those parameters. The most common method of inferential sensing uses mathematical models to infer the parameter value from correlated sensor values. However, inferential sensing is an ill-posed problem because of non-uniqueness and instability of the soluti...

Adsorption of the trace contaminant estrone, a natural hormone and commonly abundant in surface waters and in treated as well as untreated wastewaters, to eight commercial nanofiltration and reverse osmosis membranes was investigated under well defined conditions. Experiments were conducted in stainless steel stirred cells by spiking trace levels (100 ng x L(-1)) of estrone into five different ...

While microfiltration has seen wide acceptance in water treatment, the irreversible fouling of microfilters remains as biggest impediment to their long-term performance. Thus, developing a better understanding mechanisms is crucial. To this end, we investigated mechanism effluent organic matter (EfOM)-membrane interactions responsible for polyvinylidene fluoride (PVDF) membranes during wastewat...

Capacitive deionization (CDI) is a fast-emerging water desalination technology in which a small cell voltage of ~1 V across porous carbon electrodes removes salt from feedwaters via electrosorption. In flow-through electrode (FTE) CDI cell architecture, feedwater is pumped through macropores or laser perforated channels in porous electrodes, enabling highly compact cells with parallel flow and ...

The results of a field trial desalinating brackish bore water in an Australian remote National Park site are reported in this paper. Two membranes, operated with varying operation pressures, were tested with regards to flux, recovery, retention, power and specific energy consumption. The aim of such a performance evaluation is the determination of a safe operating window when the system is driv...

The Holy Grail of water technology is a full recycle of all wastewater as potable water (or water of a similar quality) after treatment by enhanced separation. Traditional wastewater treatment systems, mainly based on activated sludge treatment, have a high water loss through the sludge produced, generate a large volume of secondary waste and have insufficient quality of the product water. Newe...

The present work examines the distribution of spray water in the superheating section for steam temperature control in a once-through circulating fluidized bed (OTU-CFB) boiler. Combustion power generation has become challenging due to increasingly fast load change demands. There is also a constant need to improve power plant efficiency, which leads to extreme operating conditions and complicat...

The structure and microbial communities of biofilms developing on cross-flow nanofiltration (NF) membranes at different temperatures (20, 25 or 34 degrees C) and operation lengths (8h-24days) were studied. Feedwater comprised tertiary quality wastewater effluent or synthetic media mimicking effluents of intermediate quality. After each run, the membranes were autopsied for bacterial enumeration...
