In the ATFD (AGITATED THIN FILM DRYER) the concentrated effluent from the MEE plant is treated for complete separation of solids and liquid.

The selection of ATFD or any other centrifuge depends on the COD value of the effluent.

Many times for small industries having very little effluent generation, it is economical to use ATFD directly (without MEE). The Dry Powder obtained from ATFD can be either used as a by-product or be sent for disposal.
