The Relationship

Water hyacinth (Eichhornia crassipes (Mart.) Solms) grows very vigorously and has a high content of nutrients. Cultivation experiments were conducted on water hyacinth to check whether it is worth using for water purification and to obtain guiding principles for the practical use of water hyacinth grown in natural water channels or ponds. The average dry weight, nitrogen and phosphate content in the biomass were 5.0%, 2.5% and 0.57%, respectively. The growth rate of the water hyacinth was higher from May to June than in other seasons. The logarithmic regression equation between the growth rate (Y) and solar radiation (X) was expressed by Ln (Y) = 0.0042X-4.92 with a coefficient of correlation of 0.768. The relationship between the concentration of nutrients in water (X) and in water hyacinth (Y) is expressed by Y = Cmax.X/(Ks+X). The relationship between the relative growth rate and the concentration of nutrients was also expressed by the same type of equation. The relationship between a harvesting interval and the total yield of the water hyacinth within a given period was expressed by a mathematical model. It was made clear from the model that the shorter the harvesting interval was, the more the total yield of the crop increased.

Ground water in general is clean and fresh. However, industrialization and urbanization together with intensified agricultural activity have led to increasing demands on one hand but to the potential for large scale release of contaminants on the other. Water pollution disturbs the normal uses of water for agriculture, public water supply, aquatic life, wild life and industry. An understanding of the various types of pollutants is of considerable importance to the efficient management of water resources. Inorganic pollutants discharged into natural waters consist of mineral acids, inorganic salts, metal compounds, complexes of metal and trace elements. The proposed investigation will evaluate the underground water quality of hand pump water and Tap water of Sirgitti in rural area and its surrounding industrial areas near 7 km from Bilaspur C.G. With this objective in mind, A new and low-cost technology for purification for water by water hyacinth (Eichhornia crassipes), is a feasible solution. Water samples were collected during the growth of water hyacinth. Water purification with low-cost treatment technology using water hyacinth. The common Water Hyacinth is vigorous growers known to double its population in only 12 to 15 days. In the Water Hyacinth area and the nearby area, water pH showed a decrease between the August and September sampling followed by an upward trend and stayed stable around 9.3 in the far water hyacinth area. Water transparency showed a slow increase in August and September, and then a gradual decline in October; generally, transparency was significantly lower in the water hyacinth area than in other areas. Water Hyacinth has been used in aquatic systems worldwide for waste water purification. It has tremendous capacity of absorbing nutrients and other substances from the water and hence brings the pollution load down. In the present study an attempt was made to find the potential of Water Hyacinth in the treatment of Tap and hand pump water near industrial area of Sirgitti.

AbstractWater pollution is increasing due to urbanization and industrialization. Waste water pollution raised concern because of its influence on plants and humans. Water hyacinth (Eichhornia crassipes) is used for the removal of pollutants because of its phytoremediation efficiency. In this study, water hyacinth (Eichhornia crassipes) has been tested for simultaneous elimination of phenol and cyanide from mono and binary component aqueous solution in batch systems. The plant was grown at six concentrations of phenol and cyanide in the ratio of (10:1), i.e. 100:10, 200:20, 300:30, 500:50, 700:70 and 1000:100 mg/L in aqueous solution. The effect of process parameters such as initial concentration of phenol and cyanide and pH was evaluated. The plant was found capable of eliminating up to 96.42% of phenol (300 mg/L) and 92.66% of cyanide (30 mg/L) during the 13 days cultivation time at pH 8. The calculated Km of the root length elongation for phenol was 5.20 mm and the Vmax was 12.52 μg phenol/g root/h. However, the calculated Km of the root length elongation for cyanide was 0.39 mm and the Vmax was 14.99 μg cyanide/ g root/h. In the Eichhornia crassipes plant, the biochemical parameters such as chlorophyll, protein and sugar content have been indicated a decreasing trend due to uptake of phenol and cyanide throughout cultivation. Toxicity to 100–1000 mg/L of phenol and 10–100 mg/L of cyanide was measured by measuring the relative transpiration over 13 days. At 100 mg/L of phenol and 10 mg/L of cyanide, only a small reduction in transpiration but no morphological changes were noticed. Both pollutants are absorbed through the root of the Eichhornia crassipes plant by plasmalemma and become accumulated into the root cells and stem of a plant. Thus, this study will be beneficial for the decontamination of highly polluted waste water.
