WT-FE is used to precipitate heavy metal cations including copper, tin, and lead in a batch treatment mode from chelated wastewater and concentrates. WT-FE is a very effective precipitant that normally does not require an additional coagulant, although an anionic flocculent is typically used to facilitate precipitation. When used properly, WT-FE will reduce most heavy metal concentrations to below 1 ppm. Is not well suited for precipitation of nickelbearing wastestreams.
WT-701 is a precipitant that forms insoluble metal compounds even in the presence of complexing agents and mixed metal waste streams. The product has the advantage of being able to be introduced over a wide pH range without out gassing. Additionally WT701 is environmentally friendly to aquatic life even at high feed rate dosages and would be desirable in instances when the treated water is discharged into a natural waterway instead of being directed though a municipal water treatment facility.
WT-680 is a proprietary precipitant which combines a sulfide precipitant, sodium-DTC, and an inorganic coagulant. It is especially suited for a waste water applications when it is anticipated that multiple metals like Zinc, copper and nickel will be present in the waste stream.
WT679 is a proprietary precipitant for chelated or complexed heavy metals. This is a sulfide based precipitant blended with organic and inorganic coagulants and effectively neutralizes charges in mixed contaminant waste streams, providing excellent coagulation and solid/ liquid separation while achieving metals removal to below the parts-per-million range.
WT-676 is a proprietary precipitant for chelated or complexed heavy metals. The WT-676 contains a blend of organic and inorganic coagulants, it effectively treats mixed contaminant waste streams, providing for excellent coagulation and solid/liquid separation while achieving metals removal to below the parts-per-million range. WT-676 does not contain any form of DTC.
WT-672 is a precipitant designed to reduce Hexavalent Chrome and to precipitate other heavy metals in one step with no or minimal additional coagulant in mixed metal bearing waste streams to meet effluent discharge limits.
WT-660 is a liquid formulation designed for the removal of heavy metals from wastewater, and is a key component of an overall heavy metal removal program.
WT-140 is a heavy-metal precipitant ideally suited for treatment of a nickel-bearing waste, especially if heavily chelated. It contains sodium dimethyldithiocarbamate at a 40% concentration. It is not effective for metal reduction purposes and does not work well in treatment of lead or chromium.
