WT-528 is a medium high molecular weight coagulant with a very high charge density. In diluted form, it provides superior coagulation and performance when used in conjunction with Thio-red containing heavy-metal precipitants. Not well-suited for low-metal wastestreams where an inorganic coagulant would be better performing.
WT-470 is a concentrated inorganic/organic blended coagulant well-suited for mixed-metal wastestreams where an inorganic coagulant is necessary due to occasionally low metals loading and/or an organic coagulant is beneficial because of the presence of organic contaminants or other types of surfactants that inhibit particle formation. Intended for use in combination with a precipitant and an anionic polymer to promote solid/liquid separation.
WT-431 is a proprietary inorganic/organic blended coagulant for general coagulation requirements. Especially well suited for dosing at low pH and where organics are present that interfere with coagulation. It has been proven especially effective for processes where enhanced sedimentation or filtration is necessary or where a reduction of turbididty, color, BOD/DOD, or similar pollutants is necessary.
WT-426 is a proprietary iron-based blended product that includes an organic cationic coagulant and organic agitation agent that promotes coagulation. WT-426 is effective as a replacement for any iron-based product and helps in treating waste streams containing a high level of organics. The organic agitation agent also helps promote reduction at a lower pH.
WT300 is a proprietary coagulant used in combination with WT-430 for batch treatment of spent aqueous and semi-aqueous resist stripper. It effectively “detackifies” resist particles in the solution which can then be coagulated with WT430. The treated solution can be sent to a filterpress without concern for “blinding” the press. The combination of WT300 and WT430 are not intended for metals removal.
