The use of chlorine and chlorine containing bleaching agents in the production of bleached chemical pulp leads to the formation of a variety of chlorinated organic compounds that are discharged in bleach-plant waste waters. ...
In the present thesis we have primarily addressed ourselves to certain shortcomings noticed in the work of Mohan, Saxena and Agarwal (Astrophys. Space Sci., Vol.163, p.23,1990 and Vo1.178, p.89, 1991) which relates to the ...
The thesis starts with introducing the process and conditions of paper making with a view to have an idea about the corrosivity of the liquors and possible candidate materials of construction. Since pulping and bleaching ...
Untreated colored effluents from textile and dyestuff industries are resistant to biochemical oxidation, highly toxic to marine and human life and carcinogenic in nature. They are stable in light, impede light penetration ...
Land degradation due to soil erosion by water is a widely recognized problem. It is a serious environmental problem affecting areas of different landscapes and land use . Assessment of soil erosion from catchment area is ...
Untreated colored effluents from textile and dyestuff industries are resistant to biochemical oxidation, highly toxic to marine and human life and carcinogenic in nature. They are stable in light, impede light penetration ...
The unabated growth in the use of wireless communication is continuing and new services are being introduced. The wireless users access or share to a resource using multiple access techniques. There are three multiple ...
Environment concerns about the use of chlorine and chlorine containing reagents for pulp bleaching have led to implementation of a number of modified pulping and bleaching practices. Pretreatment of pulp so as to reduce ...
Chapter 1 indicates the importance of Recycled fibers in paper making globally. The source of global fiber supply is becoming an increasing concern due to deforestation and for the impact of fiber extraction on the ...
During the production of bleached chemical pulp, chlorine and chlorine containing bleaching agents are used, that form the chlorinated organic compounds. The bleach plants effluents are known to be the main contributor to ...
Network planning is a complicated process consisting of several phases and involves through estimation by outdoor propagation models. The final target for the network planning process is to define the network design, which ...
The thesis entitled "Process Integration for Water Management in Pulp and Paper Industry" covers different topics related to Process Water Management in a paper mill.
Chapter 1 presents need of recycling of process water ...
A wireless Ad-hoc network consists of wireless nodes communicating without the need for a centralized administration, in which all nodes potentially contribute to the routing process. A user can move anytime in an ad-hoc ...
Global demand, for environmentally sustainable products supplemented with increasing restrictions on the use of non-degradable polymers, has motivated researchers to explore for biodegradable and biocompatible polymers ...
The thesis starts with introducing the operations and processes of a paper industry. From instrumentation view point these may be termed as subsystems like raw material preparation, pulping, washing of brown stock, bleaching, ...
Brown stock washing is the key operation controlling the cleanliness of pulp with least carryover of dissolved solids on one hand and separating the maximum black liquor at as high a concentration as possible on the other. ...
The growing environmental concern regarding the impact of bleach plant effluents has
led to the progressive substitution of chlorine (C12) based conventional pulp bleaching with environment friendly elemental chlorine ...
Pulp and paper worldwide is today looking at, to gain the reputation of being environmental friendly through innovative process technologies, state of art of modem plant & machinery and compliance of stringent government ...
An Infrastructure-less wireless network Viz. Ad-hoc and Sensor consists of independent mobile nodes, a processor, some memory, a wireless radio and a power source. The main standards for decentralized Infrastructure-less ...
The Indian paper industries are using bleaching sequences where chlorine is a predominant
bleaching chemical. As a consequence the bleach plants have become a major source o f
environmental pollution contributing to high ...
