Chemical Treatment of Aquaculture Wastewater

HOME    Solutions    Chemical Treatment of Aquaculture Wastewater


Aquaculture wastewater typically contains high levels of nutrients, suspended solids, dissolved organic matter, ammonia, and nitrogenous compounds, which can pose a significant environmental threat if not properly treated.


The discharge of untreated aquaculture wastewater into water bodies can lead to eutrophication, depletion of dissolved oxygen, and the growth of harmful algal blooms. It can also introduce pathogens and parasites into the environment, which can be detrimental to human and animal health.


Chemical treatment is one of the effective method to treat aquaculture wastewater.


We conduct a wastewater treatment jar test in Bluwat Laboratory.


Step 1: Add Water Decoloring Agent to remove wastewater color


Step 2: Add polyaluminium Chloride to neutralize the charge of suspended particles and cause them to clump together


Step 3:  Adjust pH to 7-8 to promote the removal of pollutants.


Step 4: Add Polyacrylamide to agglomerate the suspended particles.


Step 5: Allow the mixture to settle for a specified period of time, typically 30 minutes to 1 hour, to allow the suspended solids to settle to the bottom of the jar.
