Iron sulphate and iron powder – effective solutions for industry and the environment
Iron products for cleaning and process optimization
How can iron sulfate and iron powder improve purification and process stability – and why do Danish plants choose to collaborate with Dankalk?
At Dankalk We supply iron-based chemical products to industrial companies, biogas plants and wastewater treatment plants throughout Denmark. The products are used for phosphorus precipitation, hydrogen sulfide control, metal precipitation and process optimization, where operational reliability and documented effect are crucial.
We combine high-quality products with technical advice, so you achieve an efficient, stable and economical solution tailored to your plant.
Iron powder
Flexible solution for hydrogen sulfide and metal bonding
Iron powder is a versatile iron product used in a number of technical and biological processes – including biogas production, water treatment and industrial cleaning.
In biogas plants, iron powder acts as an effective hydrogen sulfide binder, converting H₂S into stable iron compounds. Iron powder can also be used for phosphorus binding and precipitation of metals in process and wastewater.
Benefits of iron powder
- Reduces hydrogen sulfide and odors
- Protects motors, filters and process equipment
- Can be used for metal and phosphorus precipitation
- High purity and uniform particle size
Dankalk supplies iron powder in several varieties and helps you choose the type that best suits your purpose – whether it is purification, filtration or process optimization.

Iron sulfate
Phosphorus precipitation and environmental control without chloride load
Iron sulfate is a widely used coagulant in Danish wastewater treatment and is used for the effective precipitation of phosphorus and other nutrients. When added, iron sulfate reacts with phosphorus and forms solid compounds, which are removed together with the sludge.
Ferrous sulfate is often used where low chloride load and stable pH are required.
Benefits of ferrous sulfate
- Efficient phosphorus precipitation with low residual phosphorus
- Stable pH regulation and low corrosion risk
- Suitable for municipal and industrial facilities
- Good effect at high salinity
- Can be combined with polymers for optimal floc formation
Ferric sulfate is a strong alternative to ferric chloride and can be used advantageously where a more gentle chemical solution for installations and the environment is desired.
Dankalk advises on the correct selection and dosage based on load, temperature and process conditions.
Uses of iron products
Iron sulfate and iron powder in practice
Iron sulfate and iron powder are often used separately – but in certain processes, a combination provides extra effect.
Combination of ferrous sulfate and iron powder
- Ferrous sulfate is used for chemical precipitation and pH stabilization
- Iron powder is used for the reduction of sulfur compounds and metal precipitation
- The combination reduces hydrogen sulfide, protects installations against corrosion and ensures cleaner emissions.
Typical areas of application
- Municipal wastewater treatment plants
- Biogas plants and energy production
- Industrial wastewater treatment plants
- Flue gas and water purification systems
Dankalk offers testing, dosage guidance and full-scale testing so that the solution is adapted both technically, economically and environmentally.
