Heavy metal precipitants

Complexing agents are indispensable in modern surface treatment. Their applications are very versatile so that almost all industrial wastewater mainly contains organic complexing agents. In wastewater treatment plants, complexing agents interfere with the hydroxide precipitation of metals and can therefore lead to an exceeding of legal limits. Through the use of liquid heavy metal precipitants, heavy metals can be removed from complexed heavy metal compounds – mostly sulfidic. They can be precipitated as sparingly soluble compounds and then filtered.

KSMF 01

KSMF 01 is an aqueous solution for the quantitative precipitation of all heavy metals generated in surface treatment in the presence of low to medium organic complexing agents. KSMF 01 is preferably used in ultrafiltration systems to precipitate and separate heavy metals in the separating medium. An automatically controlled dosing by means of a redox measurement is possible.

Form	Liquid
Container	60-1.000 kg canister or Intermediate Bulk Container (IBC)
Storage capacity	min. 12 months
Safety characteristic data	Dangerous good, causes corrosion
pH value	11.9 (1 % aqueous solution at 20 °C)
Application concentration	Original solution without dilution

KVMF 10

KVMF 10 is an enhanced aqueous solution for the quantitative precipitation of all heavy metals generated in surface treatment in the presence of medium to strong organic complexing agents. KVMF 10 is preferably used in ultrafiltration systems to precipitate and separate heavy metals in the separating medium. It convinces with its good activity against nickel complexes that are difficult to treat. An automatically controlled dosing by means of a redox measurement is possible.

Form	Liquid
Container	60-1.000 kg canister or Intermediate Bulk Container (IBC)
Storage capacity	min. 12 months
Safety characteristic data	Dangerous good, causes corrosion
pH value	11.9 (1 % aqueous solution at 20 °C)
Application concentration	Original solution without dilution

KNiF 40

KNiF 40 is an organic precipitating agent for the treatment of nickel in the presence of hard complexing agents. KNiF 40 is also suitable for electroless nickel and zinc/iron as well as zinc / nickel alloy baths. Dosing is proportional to volume, an automatic control via redox potential is possible under certain conditions, but must be checked individually. KNiF 40 is suitable for use in batch and continuous flow systems.

Form	Liquid
Container	25-1.000 kg canister or Intermediate Bulk Container (IBC)
Storage capacity	min. 12 months
Safety characteristic data	Dangerous good, toxic for water organisms
pH value	9.9 (1 % aqueous solution at 20 °C)
Application concentration	Original solution without dilution
