Aqueous suspensions of aggregated silica particles have been dewatered to the point where the colloidal aggregates connect to each other and build a macroscopic network. These wet cakes have been compressed through the application of osmotic pressure. Some cakes offer a strong resistance to osmotic pressure and remain at a low volume fraction of solids; other cakes yield at low applied pressure...

Cottonwoods (Populus spp.) are adapted to riparian or floodplain zones throughout the Northern Hemisphere; they are also used as parents for fast-growing hybrid poplars. We review recent ecophysiological studies of the native cottonwoods Populus angustifolia James, P. balsamifera L., P. deltoides Marsh., P. fremontii S. Watson and P. trichocarpa T. & G. in North America, and P. nigra L. in Euro...

utilization authorities in sewage companies considered to sludge dewatering methods due to problems and challenges in this field. dewatering by sludge drying beds is considered in present study. this method is preferred to mechanical methods due to the need for very simple technology. due to restriction of natural dewatering, we tried to eliminate some of these limitations by the tests and stud...

Mechanical dewatering is a key process in the management of sewage sludge. However, drainage efficiency depends on number factors, from type and dose conditioning agent to parameters device. The selection appropriate methods sludge task laboratory work. This work can be accelerated through use artificial neural network (ANNs). paper discusses possibilities using ANNs predicting physically condi...

In this paper, the dewatering and screening process of vibrating-dewatering screen is studied by combination simulation test physical experiment. The model established method computational fluid dynamics (CFD) discrete element (DEM). Subsequently, efficiency processing are defined as evaluating indexes for performance screening. Four parameters amplitude, vibration frequency, vibrating directio...

A mathematical model considering mass and momentum transfer was developed for simulation of ethanol dewatering via pervaporation process. The process involves removal of water from a water/ethanol liquid mixture using a dense polymeric membrane. The model domain was divided into two compartments including feed and membrane. For a description of water transport in ...

Abstract A key challenge in many regulated rivers is to define adequate flow levels protect aquatic organisms. Provisioning of suitable can be pivotal bottlenecks for fishes such as salmon and trout that use the riverbed an incubation habitat. Additionally, locations where females spawn will probability embryos dewatered during period a regime. We investigated water flow, dewatering, mortality ...
