With our investment into development and fulfilment of desires of our customers, we have developed a number of products with integrated electronics applicable in various areas. The research part of our activities was strengthened in 2013 with the establishment of a research group registered with the Slovenian Research Agency.
In 2016, we completed research in the field of degradation of pharmaceuticals and other complex recalcitrant compounds in water by means of advanced oxidation processes, using electrolytic cells equipped with various electrodes, among which the most modern are the boron doped diamond anodes (BDDA). The development took place within the project LIFE PharmDegrade - Degradation of pharmaceuticals from wastewater from nursing homes and hospitals.
In 2016 we completed the project LIFE Stop CyanoBloom - Innovative technology for the control of cyanobacterial blooms. The project will enabled us to demonstrate our technology for early detection of the occurrence of cyanobacteria and other phytoplankton organisms in the aquatic environment and prevention of their excessive growth, also called blooming.
In 2018 ended the project LIFE ReSoil - Demonstration of innovative soil washing technology for removal of toxic metals from highly contaminated garden soil. Arhel participated in the project as a project partner. For the company Envit e set up a demonstration plant and made technology transfer from the laboratory to an industrial level.
In many lakes and constructed water bodies, we face with eutrophic state or increased value of plant nutrients. The negative consequence of this situation is the excessive occurrence of algae and blooms of cyanobacteria, which may be accompanied by the release of cyanotoxins.
In Arhel, we are introducing to the market a new system that allows early detection and control of the growth of cyanobacteria without the use of dangerous chemicals. The system consists of a vessel equipped with a sensor system, a water sampler, a device for the control of cyanobacterial growth and a central control system with a wireless connection that allows remote monitoring of the operation with a display of measured data.
Unlike the conventional water sampling and laboratory analysis of samples, a mobile device enables us to obtain a comprehensive spatial and temporal picture of the state of phytoplankton in the water body. More details can be found on the project webpages LIFE Stop CyanoBloom.
In the area of the fourth stage of wastewater treatment for the removal of resistant micro-pollutants, such as drug residues, we introduced a method of electrochemical oxidation using advanced electrode materials. Our innovative materials enable the formation of strong oxidants directly from the water. This avoids the use of health and environmentally harmful chemicals. More details about the technology can be found on the project pages LIFE PharmDegrade.
treatment of contaminated soil
For soil remediation, an innovative method of metal binding is applied to environmentally friendly and healthy harmless ligands, which allow the re-use of soil for the production of crops and vegetables after completion of the remediation process.
In the frame of the project LIFE ReSoil we designed and constructed a demonstration plant for the company Envit d.o.o. for soil washing using the ReSoil method.
device for laboratory preparation of soil samples
End-over-end rotator with precise temperature control MPB 1500.
Suitable for in-vitro extraction of bioavailable metals from the soil.
The problem of soils contaminated with toxic metals is the mobility and bioavailability of metals for organisms. Laboratories use various metal extraction procedures that are time-consuming and require high water and energy consumption. For the assessment of the health risk from contaminated soils, uniform standards and tests are required.
In Arhel, we developed an end-over-end rotator for the in-vitro extraction of bioavailable metals from the soil based on the most commonly used standards. The device can be used for many other extraction and incubation processes. The main advantage of the device is that it does not require a permanent working environment with water intake and can therefore be placed anywhere in the laboratory. The device is made of high quality materials, equipped with LCD display for measuring the main parameters (water bath temperature, rotation speed, rotation duration). MPB 1500 can be upgraded according to the specific needs of the user. Simple functions can be added (for example, cooling the water bath, adjusting the temperature and speed of rotation, adjusting the size of the flasks) as well as the more advanced ones (for example, installing an application for data transfer to a smartphone or a tablet).
