Effects of Liquid Wastes from Tofu Industries on Water Quality in Parangan River, Magelang District, Central Java-Indonesia

Continued entries of liquid wastes generated by tofu industries into nearby rivers might deteriorate the water quality if disposed of without prior treatments. The research objectives were to determine the liquid waste quality from tofu productions near Parangan River (Magelang, Indonesia), assess t...
