Abstract
Rapid development in intensive shrimp farming without proper planning and poor water management has resulted in the discharge of large volumes of effluent into the environment. Many treatments such as mechanical, chemical as well as biological methods have been developed and used to mitigate the levels of pollutants released from intensive shrimp culture. This study focused on an integrated wastewater treatment system for managing effluent from intensive shrimp farming in Tam Giang lagoon, the biggest lagoon in the Asian region. In this study, a simple mechanical method followed by two stages of biological treatments was assessed to develop integrated wastewater treatment systems. The specific objectives of the studies were to (i) evaluate and optimize the conditions for mechanical treatments for maximize ammonia (NH3) toxicity removal and enhance oxygen levels; (ii) examine the conversion of organic matter (OM) into bio-available nutrients using three local fish and a mangrove snail species; (iii) reuse nutrients to produce aquatic biomass using locally available seaweed and molluscs and (iv) evaluate the integrated wastewater treatment system performance consisting of three treatment stages.
