  • Electric treatment for hydrophilic ink deinking

    Hydrophilic inks have been widely used due to higher printing speed, competitive cost and being healthy non-organic solvents. However, they cause problems in both product quality and process runnability due to their hydrophilic surface wettability, strong negative surface charge and sub-micron size. Electric treatment was shown to be able to increase the ink sizes from 60 nm to 700 nm through ...

  • Use and application of Piezocone Penetration testing in Presumpscot Formation

    Abstract: This paper examines the advantages and limitations of CPTu and SCPTu as an exploration method for geotechnical engineering of Presumpscot Formation. Discussion will include typical results of CPTu and SCPTu data for Presumpscot Formation, application and use for settlement prediction, bearing capacity analysis, slope stability evaluation, and seismic design considerations. Intent is to ...

  • Study on kinetic parameter in real yarn dyed wastewater treatment using electrocoagulation-ozonation process

    Treatment of real yarn dyed wastewater using hybrid electrocoagulation (EC)-ozonation process has been carried out to solve the non biodegradable wastewater. The work aimed to treat the real yarn dyed wastewater under different ozone concentration and agitation speed and to estimate the kinetic parameter of ozonation. The effect of ozone concentration, agitation speed were studied to give the ...

  • Should Your Sensor Have A Connector Or Pin Terminals?

    When it comes to measuring the activity of your project, it’s nice to have options. High precision sensors can offer plenty of selections from the range of your measurements to the output of your readings, but a sensor is only as good at its connection. Connectors and pin terminals are common and dependable connections that relay your readings from within the sensor to the screen in front ...

  • Fly Ash Treatment – Plasma Torches versus Graphite Electrodes

    Background Plasma generating devices have to be designed to tolerate incredibly harsh conditions during operation and in particular very high heat loads and temperatures around the arc. However, when used in the vitrification of highly chlorinated materials the challenge is even greater than in other applications. The combination of high ...

  • Understanding Geographical Instrumentation

    Geographical instrumentation is one of the much heard terms especially in the field of building. Anywhere, where construction is carried out then services rendered for site examination plays an important role. It helps in identifying possible risks and also effectiveness present within the current site or structure.  Designing of the Site The basic step which is carried out ...
