Navy Wastewater MOP-UP (trademark)
Abstract
Many Navy wastewaters contain complex mixtures of metals and oils/greases, which are extremely difficult to treat. Biopraxis is developing a proprietary approach, based on particulate MOP-UP reagents, already shown to be capable of taking heavy metals to sub-parts per billion (ppb) levels in complex freshwater wastes such as shipyard stormwater runoff. These MOP-UP reagents have extremely high loading capacities; therefore, fewer consumables are needed, and far less secondary waste is produced. The simple production method will make it possible to manufacture reagents in bulk at very low cost. By coupling MOP-UP reagents with off-the-shelf separation systems, economical, user- friendly, wastewater treatment systems can be produced. The objective of the Navy Wastewater MOP-UP program was to evaluate the feasibility of using MOP-UP to treat heavy metals and oils/greases in saline wastewaters. A variety of reagents screened against copper and zinc in artificial seawater were shown to take the metals to nondetectable levels, and to take up as much as 450 mg Cu/g reagent and 1,030 mg Zn/g. They were also very effective against representative components of oils and greases (alkanes, BTEX. and PAHs).
