Dear Rosemary, Thank you for your answer. Grey water is not available. My problem deals with an area where is no fresh water at all and the fresh one (from rains) is being expensive and used for cooking and drinking (if any surplus for washing). There is but a plenty of sea water. Instead of sending it back to the ocean (I consider it too) think if an active sludge process could be applied for such a "waste sea water" similarly like for sewage of fresh water, or the presence of salt unable it.
