Abstract

Surface sediment particle sizes, their spatial distribution and their geotechnical characteristics in the Ambalapuzha-Purakkad Mudbank were studied, based on field observations during pre-monsoon and monsoon seasons. The study revealed that sediments in the mudbank are clayey silts in both the seasons. The magnitude of the fine silt and clay contents blanketing the ocean bed were however, observed to be more in the pre-monsoon season indicating the possibility of fine silt and clay going into suspension during the monsoon season. Geotechnical properties of surface sediments revealed that they are highly plastic, with high liquid limits. Organic carbon, fine silt and clay minerals play an important role in the behaviour of mudbank sediments.

Abstract

The paper deals with recovery and separation of crude oil from sea water in case of oil spills. It is based on the principle of absorption of oil contaminated water by textile media followed by its extraction and separation of oil from sea water. Various textile composites are used for this purpose and the optimal fibre blend is found. Machinery and method for recovery of oil is analysed.
