9. Recommendations for Wastewater Treatment
Rinse water and Concentrates can be treated by a neutralization precipitation.
Concentrates should be diluted with the rinse water in the ratio of 1:3 and then neutralized
with caustic soda / calcium hydroxide to pH 9-10 .
For better flocculation add flocculation agent (recommended is polyacryl amide/anionic with a molecular
weight of 4-6 million) and stir. Allow the precipitate to settle for better filtration.
