Wastewater Treatment
The vessels mixed gray and black water from mixing TK are filtered by two
screen filters; the filtered wastewater is introduced into the Bioreactors. The
solids, which are collected by the primary screen filters are transferred, by the
solids transfer pump into the stbside bio-residue TK. The solids that are collected
into the stbdside bio-residue TK transferred by the sludge transfer pump into the
two dewatering units (SOMAT) and with the help of the chemical named polymer
the separation of solids and water is achieved.. The solids are then collected into
the solids collecting TK of the SOMAT system and then transferred into the
incinerator for burning. The water that remains from the separation, which the
dewatering system achieves, is transferred by gravity into the mixing TK. The
wastewater that is introduced into the bioreactors is treated and the treated
permeate water is stored into treated gray water holding tanks. The treated
permeate water passes through UV units before it is discharged into the sea.
