Increasing Pile Capacity And Set-Up In Clay By Electrokinetics, Susheel R. Kolwalkar
Increasing Pile Capacity And Set-Up In Clay By Electrokinetics, Susheel R. Kolwalkar

A significant increase in the load capacity over a period of time is often observed in driven piles. This time dependent strength gain is termed as 'set-up'. Different mechanisms have been proposed to explain the set-up phenomenon in cohesive soils. A research was initiated to investigate this mechanism in clay soils in terms of electrokinetic theory and explore the possibility of accelerating the process. The system chosen for the study consisted of laboratory scale steel piles driven in kaolinite clay under controlled conditions. The piles were subjected to DC voltage gradients with surrounding electrodes at different time intervals and their …

Dietary supplement wastewater contains higher order polysaccharides such as the complex sugars maltodextrin and low fat milk. These complex sugars contain a significant amount of organic carbon therefore, presence of these sugars can pose threats to the environment if discharged without treatment. While many food processing plants are required to send their waste through wastewater treatment, legislation may require preliminary treatment of these wastes in order to satisfy the effluent discharge requirements. Because of the high organic carbon presence, it would be preferable to use biological treatment methods to reduce the organics present within the system. Microorganisms are capable of …
