Systems with physical separation method
Contaminants in industrial waste water represent a high ecological and economic burden, which can be reduced with different filtration methods many times over. Depending on the substance to be removed and their sizes, different filtrations are used. It is also possible to subject the liquid to be purified in a test run in the test system at the Schwabach facility.
An overview of the possible filtration processes:
Reverse osmosis (RO = reserve osmosis) is a membrane process for the separation of dissolved substances (salts, macromolecules) from a liquid. Reverse osmosis reverses the principle of osmosis. It is used when pure water, i.e. pure H2O, is required.
The ultrafiltration pore membranes have a porous structure with channels. The selectivity is based on a sieve effect, which is determined by the pore size distribution of the membranes. In practice, the processes are usually controlled by a cover layer (secondary membrane) which is formed from the ingredients concentrated in front of the membrane.
Nanofiltration membranes and nanofiltration processes differentiate between monovalent and divalent ions and quantitatively retain the dissolved low-molecular organic compounds. Their separation performance is essentially based on the principle of size exclusion, i.e. the sieve effect.
The microfiltration systems manufactured by LK Metall work according to the proven physical process of cross-flow filtration with chemically very robust and extremely resistant ceramic membranes. Based on the filtration method of membrane filtration, it is possible to continuously e.g. Filter out suspended matter, emulsified oils, oils and bacteria and thus optionally regenerate the medium so that it can be reused as process water or discharged into the sewer.
Ingeniously simple, simply Ingenious is our LK tangential separator for separating solid and liquid particles using the centrifugal principle. Excellent for separating aluminum and magnesium particles, suspended matter flakes from biological water treatment systems as well as glass or ceramic particles up to 5μm.
