Technology
Selecting the right water purification technology is the key to obtain safe drinking water.
Because of its high efficiency and flexibility in utilizing different raw water sources, we use ultrafiltration as a core technology in our water purification systems. Ultrafiltration does not require any chemicals, offers excellent and consistent product water quality and can be combined with a variety of other drinking water treatment processes.
We offer media filtration, activated carbon filtration and UV-disinfections to create a multi barrier system (MBS) within the entire treatment chain – from pumping and cleaning up to disinfection and storage.
Media Filter
Pre treatment to remove e.g. iron, manganese, arsenic, high turbidity and much more elements
Ultrafiltration
Main treatment to remove 99,99% of colloids, bacteria and viruses from “dirty” and microbiological contaminated surface water or well water
Activated carbon filtration
Post treatment to improve the taste and smell of the purified water. Activated carbon removes dissolved organics and some heavy metals.
Ultraviolet disinfection
Final treatment and a additional disinfection step after drinking water storage to avoid recontamination on storage level.
Multi barrier system design (MBS) through optional accessories
Ultrafiltration in detail
Ultrafiltration, often abbreviated as UF, is a physical membrane filtration technology in which water is filtered at low pressure (0-1 bar) through a semi-permeable membrane. The typical pore size of ultrafiltration membranes is between 0.01 μm and 0.1 μm. During filtration, suspended solids, colloids and high molecular weight substances are retained by the membrane, while water and dissolved substances that are smaller than the membrane’s pore size can pass through the membrane. Ultrafiltration technology reliably retains up to 99.99 % of microorganisms, bacteria and viruses, while natural minerals are retained in the treated water.
As a low-pressure membrane technology, ultrafiltration is extremely effective and has a high water yield (up to 99%). Ultrafiltration is increasingly being used in advanced drinking water treatment processes around the world. Compared to conventional treatment (sand filtration + chlorination), ultrafiltration has many advantages, such as the consistent quality of the water produced, ease of automation, reduced space requirements and savings in operating costs.
Ultrafiltration does not require any chemicals for treatment.
