Sludge Dewatering by Impulse Drying

An innovative and energy efficient sludge dewatering technology has been developed. The technology, impulse drying, involves briefly contacting the sludge under pressure with a heated surface. A unique feature of impulse drying is that the majority of moisture removal occurs as lipid water. A pilotand laboratory-scale demonstration was performed on low ash primary paper mill sludge. The pilot-s...

Liquid pressure measurements in a thermally assisted mechanical dewatering process

The thermally assisted mechanical dewatering process, investigated in this paper, couples in one stage mechanical dewatering at low pressure (Papplied < 1125 kPa) with a moderated heating (T < 80°C). Former studies emphasized that the separation enhancement depends on the product. To identify the mechanisms involved, a 1D filtration/compression cell is instrumented with pore liquid sensors dist...

Molecular Dynamics Simulation of Potassium Chloride Melting (II. Constant Volume and Constant Pressure Simulation of Filled System)

We have used a simple ionic potential to simulate the melting of KCI pseudo-infinite crystal. Two MD simulations, one with constant Volume and the other with constant pressure condition are performed. These results are compared with the previous micro-sample simulation results. In the constant volume simulation the melting temperature increase substantially with increasing pressure. A method fo...

Pressure-Sensitive Adhesives versus Tacky Gels

By definition, transdermal, drug-delivery applications mandate the use of adequate adhesive systems to not only keep the pharmaceutical agent in contact with the intended surface, but to facilitate sustained, controlled delivery. Engineers who must determine which silicone chemistry is optimal for their device have a few options. While pressuresensitive silicone adhesives (PSAs) have typically ...
