Modelling dynamics of organic carbon in water hyacinth Eichhornia Crassipes (Mart.) Solms artificial wetlands

The role of water hyacinth on removal of organic carbon was investigated in free water constructed wetlands. A model incorporating the activities of suspended and biofilm biomasses was developed in order to simulate the various processes involved in the transformation and removal organic matter in the water hyacinths constructed wetland. The results show that the major processes governing the organic carbon...

Prospective techniques for in-situ treatment and protection of aquifers: A sustainable hydrology review

Most water table aquifers are polluted, yet they are the primary sources of urban and rural water supply. Sustainable hydrology in this millennium will capture in-situ treatment and protection of shallow aquifers particularly in developing countries. Permeable reactive barrier (PRB), biological and electrochemical methods with air and steam injection techniques will advance. Ex-situ pump and treat method is slow, costly...
