Large-scale production and extensive application of synthetic dyes can cause considerable environmental pollution and are serious health-risk factors. Although, the growing impact of environmental protection on industrial development promotes the development of eco-friendly technologies. Release of considerable amounts of synthetic dyes to the environment causes public concern, legislation problems and is a serious challenge to environmental scientists. In the present study the plant seed powder has been used as a substance for dye effluent treatment. The degradation efficiency of seed powder has been tested and compared with the chemical treatment. The Dodonae viscosa seed powder is taken in the following five different concentrations 1, 2, 3, 4 and 5 g/l by standard jar test method. The raw dye industry effluent is treated with the seed powder. The effluent colour is degraded and changed to light yellow colour after a period of 13 h. The colour, pH, turbidity and total suspended solids were greatly reduced when compared with the raw effluent. The optimum dosage for decolourisation and the optimum dosage for the reduction in pH, turbidity and total suspended solids were found to be 5 g/l. This is highly effective when compared with the chemical counterparts. The COD of the effluent has also reduced slightly when compared with the hypochlorite treatment. Although the application of plant based natural seed powder in the degradation of dye effluent is still at its infancy, they are technically promising in terms of efficiency for further research. |
