STUDY ON REMOVAL OF CADMIUM FROM WATER ENVIRONMENT BY ADSORPTION ON GAC, BAC AND BIOFILTER



INTRODUCTION

Cadmium is introduced in to bodies of water from smelting, metal plating, Cadmium-Nickel batteries, phosphate fertilizer, mining, pigments, stabilizers, alloy industries and sewage sludge. The harmful effects of Cadmium include a number of acute and chronic disorders, such as “itai-itai” disease, renal damage, emphysema, hypertension, and testicular ....etc

Digital Image Processing Techniques for the Detection and Removal of Cracks in Digitized Paintings
Abstract: An integrated methodology for the detection and removal of cracks on digitized paintings is presented in this project. The cracks are detected by threshold the output of the morphological top-hat transform. Afterward, the thin dark brush strokes which have been misidentified as cracks are removed using either a median radial basis function neural network on hue and saturation data or a semi-automatic procedure based on region growing. F ....etc

SEWAGE WATER AS THE SOURCE OF IRRIGATION AND PLANT NUTRIENTS


INTRODUCTION
Supplies of good quality irrigation water are expected to decrease in future because the development of new water resources will not keep pace with increasing water needs of agriculture, industries and municipalities. some of these future water needs can be met by using available water supplies more efficiently but in many cases it will be necessary to make increased use of municipal waste waters and agricultural drainage water. agricul ....etc

ABSTRACT
Due to the growth in population and industrial growth the demand for power is increasing in the country by leaps and bounds. But the power production through hydro-electric projects and through nuclear power projects is not keeping pace with the demand. Thermal power offers a ray of hope in this scenario. Power development is the key to the economic development. The per capita consumption of electricity in the country also increased from 15 kWh in 1950 to about 338 kWh in 1997 -98, which is about 23 times. H ....etc

WORKING PRINCIPLE:



Attach length copper wire to one stick and make two points (top and bottom) on other stick with copper wire; and mark them point A, B, C as shown in the diagram. Connect points A, B and C to the main circuit. The IC 555is used in the circuit as an astable multivibrator. The IC is an 8pin duel-in-line IC. When there is water in between the points A and C, pin no 3 voltage of the IC becomes high and transistor BC 148 op ....etc

Concrete is the most used construction material in the world and if correctly composed, it can be vary durable and thus save considerable society resources in maintenances cost. Self-compacting concrete is one of the subjects of concrete technology and the various investigations have been carried out and hence the concrete has been used in practical structures. In this paper, a brief introduction to self-compacting concrete (SCC) is given. And also the definition and motive for development of SCC have been discussed. The SCC has some advantages ....etc
