Treatment of Domestic Wastewater by Aquetic Plants

Portable water sources are reducing in globe around day by day. One of the techniques to enhance water quantity is recycle or reuse of water. Water reuse can be done best by treatment of waste water. Domestic waste water is treated in traditional method with primary treatment, secondary treatment and if necessary tertiary. This method either utilizes energy or has low efficiency. In wastewater treatment, one of the most sophisticated methods of wastewater treatment is the tertiary treatment or biological treatment. A large number of inputs in the form of capital investment and energy have been placed for few decades now for meeting up the wastewater treatment objectives. To compensate these costs, natural wastewater treatment technologies, particularly the application of aquatic plants for wastewater treatment have been considered for quite long. The ability of aquatic ecosystem, mainly the aquatic plants to carry out wastewater purification has been exploited and this forms one of the major principles for natural wastewater treatment technologies. This study report, constitute of various underlying concepts and principles involved in the wastewater treatment using aquatic plants.
