This process makes it possible to reuse the water, thus reducing the need to buy and ship water in as well. ...

It is generally agreed that construction and demolition waste (CDW) management practices should be guided by the "3R" – reduce, reuse and recycle – principle (Peng et al., 1997).However, the effectiveness of embracing such practices in China, where CDW accounts for about 30%–40% of the total municipal waste, is still very limited; the recycling and reuse rate …

The Detailed Design Study on HCMC Water Environment Improvement Project Final Report Main : Volume 2 8-5 Phase I is estimated at 108.5 m3/m2/day, if one (1) train of PST will be constructed in Phase I. This is little higher than the design standard of 100 m3/m2/day, which is defined from the result of wastewater treatment experiment works (WTEW), but it is still in the

In plants that processes only construction site waste, sorting is often carried out manually at sorting belts. Plants in which construction site waste as well as post-consumer and commercial waste are processed together are equipped with various sorting units up to sensor-based sorting in order to separate the heterogeneous material flow.

In order to improve the treatment efficiency of the construction waste in the subway projects, solve the problem of no-storage for construction waste and realize resource reuse, this paper analyzes the traditional construction waste treatment process, an ecological technology of construction waste treatment was developed mainly based on zero emission & 4R (reduce, …
