Abstract

Demand for milk and milk products caused vast growth of dairy industries in most countries of the world. Consequently, the amount of wastewater and waste material generated and discharged from these industries has also increased. Phytoremediation provides eco-friendly, low cost treatment approach for the waste water treatment. In the current study aquatic macrophytesEichornia and Lemna were taken in account individually and in combination. A wetland approach was used for the treatment of effluent (waste water) from Parag Dairy and Milk processing plant, Meerut. Effluent was then transferred to glass aquarium and analysed for Physico-chemical parameters viz. Temp., pH, Turbidity. The initial parameters of the raw waste water were recorded Temp 25.34oC, pH 5.8, Turbidity 648 NTU. After the treatment, 75 % removal of turbidity was recorded in case of Eichornia (486 NTU), while Lemna showed a potential of 54 % removal (350 NTU) of turbidity

Highlights

Industrial development and explosion of population are the primary reasons for the dwindling water quality as the pollutant load is increasing day by day in the water bodies
MATERIALS AND METHODS Experimental plants: The plants used for the study included floating wetland macrophytes Lemna and Eichhornia were collected from local pond
The experimental plants were initially subject to stabilization in glass aquariums containing tap water for 15 days for acclimatization

Summary

Introduction

Industrial development and explosion of population are the primary reasons for the dwindling water quality as the pollutant load is increasing day by day in the water bodies. The dairy industry is one of the most polluting of industries, it generates about 0.2–10 litres of effluent per litre of processed milk (Vourch et al, 2008). Such wastewaters and waste material, if discharged without proper treatment, severely pollute receiving water bodies. The minimization of waste and reductions in material and energy inputs are the most important environmental aims. Aquatic plants play an important role in structural and functional aspects of aquatic ecosystems by various ways and phytoremediation is one of them. Phytoremediation includes the use of plants as well as microorganisms of the rhizosphere to remove or render harmless pollutants from contaminated sites (Lasat, 2002). Waste water treatment with culture of aquatic macrophytes such as Eichornia, Pistia, Lemna, Typha etc. for the purpose of pollution abatement has received growing acceptance (Swati et al, 2011)
