Water Hyacinth Treatment of Domestic Wastewater

Water Hyacinth (Eichhornia crassipes) is a fast-growing free-floating aquatic weed having a unique survival capacity and a quest for nutrients to grow. Complete eradication of water hyacinth is quite impossible and hence utilization of its scavenging capacity has been the only way out to get rid of this obnoxious weed as well as to meet out the requirements of treating large volumes of waste waters due to increased population and economic development world over. The aim of this book is to present the positive aspect of water hyacinth through its utilization and at the same time to come out with an easy economical and efficient method of treating domestic waste water. This method is quite efficient in removing pollutional parameters of domestic waste water such as BOD COD suspended and dissolved solids etc. Another advantage is re-use of the treated waste water for non-potable purposes like industrial agricultural or gardening etc. and furthermore the plant biomass produced during the process can be used as a fertilizer animal feed soil enrichment material and a good source for production of bio-gas with high percentage of methane.
