Abstract:
A purification process for waste water from a textile plant and other manufacturing processes. After preliminary filtering to remove foreign particles, the waste water is treated with a reducing agent, if needed, and the pH adjusted to 8. 0-9. 5. The waste water is then treated with a flocculating agent. After further treatment in a clarifier, the waste water is passed through a sand filter to remove any residual suspended solids. The pH is adjusted to below about 6. 0 and the waste water is then subjected to reverse osmosis.
