For potable water conditioning
The pipeline network is known to be a major factor affecting the quality of the drinking water that reaches the consumer. Both the water quality and the pipeline network are influenced by corrosion reactions, which are often a cause of rusty water. In turn, corrosion reactions are largely dependent on the quality of the water and on the materials the pipes are made of - especially cast iron and steel.
The resulting problems define the field of activity in which we, as partners to municipal utilities departments, with more than 25 years of experience, supply professional solutions, often in cooperation with respected institutes. We also put these solutions into practice.
The phosphate and carbonate-activated silicate solutions for use in the multiphase or the integration process are suitable for:
- corrosion inhibition in water-transporting metal systems
- prevention of rusty water and of accumulation of iron in water
- reduction of general corrosion in copper pipes
- limitation of lead emissions from existing lead pipes
- stabilization of water hardness in hot water
METAKORIN inhibitors for the potable water sector are hygienically harmless conditioning substances, which conform to international standards.
The harmlessness of all phosphatic and non-phosphatic carbonate-activated silicate combinations and of the phosphates has been attested by the DVGW-Technologiezentrum Wasser in Karlsruhe, Germany.
Carbonate-activated silicates, which are produced in a variety of modifications, form the basis of all METAKORIN inhibitors.
The starting material for producing sodium silicates is silicon dioxide (SiO 2), which is present as crystals in quartz sand. In a special process, the finely ground quartz sand is liquefied at high pressure and temperatures to form sodium silicate. A further quality-relevant step isthe carbonate activation of the silicates – a process which enables silica cross-linking to be discretely controlled.
The earth’s crust contains 25% silicon, making this the second most abundant of all the elements. Silicon is found in many living organisms. In plants, it is present in soluble and insoluble, highly polymerized, as well as organically bonded, alcohol-soluble form. The total silicon content of the human body is about 1 gram. Blood contains roughly 1 ppm of silica. Bones contain up to 100 ppm. Silicon is a component of connective tissue. Adequate quantities of silicon and copper are needed to maintain the elasticity of the connective tissue. The current popularity of bran as a source of roughage has resulted in an increased intake of silicon, as all plant fibers are rich in this element.
Food from animals contains 0.3 - 4 mg SiO 2/100 g. Grain, however, is the main nutritional source for humans. Our daily consumption of silica varies between 50 and 250 mg. As our bodies only contain a total of 1 gram of silicon, it is safe to assume that the excess silicon passes out quickly through the kidneys. Our daily intake of phosphates, which act as a reserve for the creation of essential organic compounds and also play a role in intermediate metabolic processes, should be 2500 to 4000 mg PO 4 (phosphate). When METAKORIN products are used in the usual amounts, between 1.0 and 2.0 mg PO 4 are added per liter of drinking water. Relative to our total requirement, these amounts are negligible.
