fig1 are a tug push notch 163 and an anchor windlass 164 0092 fig1 shows a section through the water treatment vessel further highlighting the main deck enclosure 153 the membrane module racks 154 located below deck and the equalization and pretreatment tanks 157 the design layout shown in fig1 through 16 can be readily modified to accommodate the installation of an immersed pressurized membrane system or supplementary treatment operations its presentation is in no way intended to limit the scope of the application to either low pressure or immersed membrane systems and is intended only to illustrate additional detail associated with the barge mounted treatment vessel concept an isometric view in fig1 shows an integrated dredging system which includes a water treatment vessel 151 a contaminated sediment remediation vessel 101 an excavator barge 171 with a supporting hydraulic excavator 172 a solids stabilization and transportation vessel 173 with a hopper screening plant 174 and containment ramps 175 to connect the contaminated sediment remediation vessel 101 with the excavation barge 171 and the excavation barge 171 with the solids vessel 173 to prevent spillage of sediment during the excavation process also shown in fig1 on the solids stabilization and transportation vessel 173 are storage containers 176 and a conveying system 177 screened sediments from the hopper screening plant 174 and a cementitious stabilizing reagent such as portland cement which is stored in a silo.
