Product Introduction :
Aquamet products (Nouryon Akzo Aquamet)
 
Aquamet® M 
(Sodium Dimethyl-dithiocarbamate)
• The most cost effective product.
• The most forgiving during application.
• It is the most durable in acidic or oxidizing environments and will not degrade as easily as
   the other materials. This property makes it a better choice for low pH conditions, such as
   when the pH is lowered to help free the metal from a strong complexing or chelating agent.
• It agglomerates well, but can sometimes tend to form “floaters” on the water surface.
 
Aquamet® T 
(Sodium Trithiocarbonate)
• It is not a dithiocarbamate.
• It forms a denser sludge than the other products, with less volume and weight, which can         result in lower sludge disposal cost.
• The agglomerated sludge is more fragile and can re-disperse into much smaller particles,
   which do not settle out well. This problem can be easily overcome, however, by the addition
   of a coagulant.
• It is the most susceptible to degradation in acidic or oxidizing environments, and could 
   require slight overdosing to compensate for this loss.
 
Features and benefits
Aquamet products precipitate complexed and/or chelated metals and mixed metals, such as copper, nickel, zinc, chromium, cadmium, silver, lead, iron, and mercury. The resulting metal complex is extremely water insoluble and readily precipitates out in solution. 
 
This precipitate forms a dense, compact, chemically stable sludge, that settles rapidly and can be esil dewatered. This lower volume sludge offers lower disposal costs and can be disposed of by direct incineration, permitting precious metal recovery. 
 
The Aquamet products minimize settling and clarification time in polish systems that re not effectively treated by alternative precipitation techniques, such as sulfide, sulfate, or hydroxide precipitation. 
 
These products function effectively at lower pH levels than those required for traditional hydroxide precipitation. The Aquamet products are chelating agents and can take metal away from most other chelating agents. 
 
Aquamet products also act as reducing agents. They can reduce Cr6+ to Cr3+
