An experimental wetland system was constructed to upgrade the water quality of piggery wastewater. Transplanted aquatic macrophytes were successfully established within the wetland.

Power quality can be defined as any power problem faced in the frequency, current or voltage deviation which leads to mal-operation of the customer’s equipment. It has been always difficult to maintain the quality of electric power so as to keep it within the acceptable limits. Mainly the use of power electronics devices that acts as the nonlinear load is responsible for the degradation in the poor power quality. Poor power quality results in various problems in the distribution systems like higher power losses, harmonics, sag and swells in the voltage, poor distortion and displacement factor.
