Ferric chloride as a cleaning agent for waste water

Ferric chloride from FERRO DUO impresses with its excellent chemical properties and is ideal for the treatment of waste water.

Wastewater treatment and processing are our competence

Ferric chloride from FERRO DUO impresses with its excellent chemical properties and is ideal for the treatment of waste water. Our iron and aluminium salts are used in a variety of ways around the globe to treat and reprocess wastewater. Ferric chloride is indispensable in this process; it eliminates phosphate and hydrogen sulphide and ensures decolourisation and chromium reduction of industrial waste water. Digester gases and biogases are desulphurised by our effective ferric chloride and health risks are minimised.

Ferro Duo products for waste water treatment:

• Ferro Aqua S -Premium product for water treatment
• Ferro Aqua T for waste water treatment

For clean water: Ferro Aqua S

Ferro Aqua S is a Ferro Duo premium product for water treatment and delivers impressive results. Due to the constantly increasing population density and the advancing industrialization, more and more water is withdrawn from the natural cycle for consumption. Ferro Aqua S is used in simultaneous precipitation for wastewater treatment. The clarified and purified water is returned to the water cycle. The iron (II) sulphate heptahydrate contained in Ferro Aqua S has excellent chemical properties and is used worldwide. Ferro Aqua S eliminates phosphate and hydrogen sulphide, decolourises the water and, in the case of industrial waste water, provides the necessary chromate reduction. Any fermentation and biogases are desulphurised by Ferro Aqua S.

Ferro Aqua S in the cement industry

Ferro Aqua S reliably delivers excellent results in the cement industry as a chromate reducer. In contrast to Ferro Mono 30, Ferro Hepta contains seven moles of water of crystallization, whereas Ferro Mono contains iron (II) sulfate with one mole of water of crystallization. Since Ferro Aqua S dissolves very quickly in water, it is able to reliably reduce even high chromate contents. This makes it possible to produce cement with a chromate content that is harmless to health.

Due to its outstanding properties, Ferro Aqua S has been used extremely successfully for decades as a raw material for the production of iron-based color pigments. It is also suitable for special applications, for example for transparent, color-changing pigments or as food coloring.

Water treatment with Ferro Aqua T

Due to the increasing population density worldwide and the advancing globalization, water is continuously withdrawn from the natural cycle for consumption. Ferro Aqua T from Ferro Duo treats the water to a high quality and purity. Ferro Aqua T is mainly used for waste water purification in the simultaneous precipitation process in order to introduce purified and clarified water into the water cycle. Thanks to the iron (II) sulphate heptahydrate it contains, Ferro Aqua T has excellent chemical properties and is used globally. Phosphate and hydrogen sulphide are eliminated with Ferro Aqua T, which reduces chromate and decolourises the water.

Ferro Aqua T binds hydrogen sulphide

Depending on the raw materials used, the production of biogas can lead to increased to very high levels of hydrogen sulphide in the biogas. In addition to the toxic properties of hydrogen sulphide, especially for the methane-forming organisms, a high hydrogen sulphide content also poses an extremely high risk of engine damage to the coupled combined heat and power plants. Ferro Aqua T already reliably binds harmful hydrogen sulphide in the fermenter, thus allowing not only reliable operation of the CHP units but also feeding into the public grid.

For the cement industry, Ferro Aqua T has been delivering excellent results as a chromate reducer for years. The Ferro Mono iron(II) sulfate contained in Ferro Aqua T contains one mole of water of crystallization, whereas Ferro Mono 30 contains seven moles of water of crystallization.
