The characteristics of pre-regulated American cements differ fundamentally from those manufactured afterwards, both in terms of physical and chemical properties and with regard to cement consistency. This paper presents ...
Despite being considered one of many seventeenth century American wall insulation systems, brick nogging emerges as a prevalent construction type throughout all of original colonies. Used in both framed and hewn-log ...
Sustainability in the construction industry can only be achieved through a radical rethinking of building construction and reuse. This paper outlines the problems and offers innovative solutions that embrace technological ...
Settling behaviour of polymer conditioned water-treatment sludge was investigated in this study for the purpose of a better understanding of a so-called “CML30 method”, which was developed in previous study to evaluate the ...
Two separate sets of reed bed systems were operated in parallel for the purpose to study a comparative behaviour of high strength animal wastewater treatment. Each system consisted of five-stage gravel-based reed beds. The ...
Problems concerning the management and utilization of sludge derived from water treatment processes are still not fully solved. A common approach is direct discharge to a landfill site. This study provides experimental ...
A gravel-based tidal flow reed bed system was operated with three different strategies in order to investigate its optimal performance for the treatment of high strength agricultural wastewaters. According to the three ...
Several recent articles and discussions in GIN, by Penman (2002), Thomann et al. (2003),
Ridley (2003) and Sellers et al. (2003) highlight the importance of pore water pressure
and suctions and in particular the difficulties ...
The purification capacity of a laboratory scale tidal flow reed bed system with final effluent recirculation at a ratio of 1:1 was investigated in this study. In particular, the four-stage reed bed system was heavily loaded ...
On the basis of experiments carried out using an image analysis system and static zone settlement, the alum sludge floc structure and the floc packing status with varied polymer dosages were examined in greater detail to ...
