Abstract
A process for treating water is provided where the water is mixed with an inorganic reagent powder such as powder activated carbon. Organics and micropollutants are absorbed by the reagent powder. After the reagent powder has been mixed with the water, the water is directed to a setting tank and sludge from the water settles to produce a clarified effluent. Forming a part of the sludge is the reagent powder previously added. Sludge is collected and directed to a separator that separates the reagent powder from the sludge. Separated reagent powder is recycled and mixed with the water being treated.
