The technology is a 3-step sludge handling process. It works by de-nitrification of the RAS process water, converting nitrate into free nitrogen that is released in the air. The water is returned to the RAS after a step that removes phosphorus and other inorganic compounds from the process water. Zero discharge RAS water treatment plant- ZDRAS has easier the technique by using HDPE Geomembrane pond liner in Bangladesh.
Aquaculture System: Zero Water Discharge for Vannamei Shrimp and Prawn Farming in Bangladesh
The ZDRAS is a land-based fully-closed aquaculture system based on a recirculation technology cycling water through filtration processes and returning it back to the system without discharging any waste to the surrounding environment. Zero discharge RAS water treatment plant- ZDRAS has easier the technique by using HDPE Geomembrane pond liner.
It is very easy to do zero discharge RAS system water treatment which is now available in Bangladesh at low cost.
The ZDRAS does not require direct water access, making it fully operational in any environment, under any climate conditions. It gives you a great flexibility in species selection, allowing you to choose according to your local market demand. Production can be scaled easily thank to our Osmosia design. Using Hdpe pond liners in RAS shrimp farming results in a much lower cost of production if shrimp are grown at a higher density.
