Zneškodnění mikrobů v kapalinách pro dezinfekci; rozrušení mikrobů pro získání proteinů; významné snížení úrovně COD/DOCl v odpadních vodách.

Technologie švýcarské společnosti využívá nový ty reaktoru pro zpracování jakékoliv kapaliny (emulze) - např. mléko, rozpustné oleje nebo kapaliny na bázi vody, u kterých může výrazně snížit úroveň COD/DOC a odstranit nežádoucí organické molekuly (TOC/AOX). Hlavní výhodou je rychlost s jakou je tato technologie schopna nahradit velké systémy (UHT-úprava s nerezovými tepelnými výměníky) a schopnost pracovat za normální a nízké teploty. Nabízíme licenci na tuto technologii nebo její dodávky.

Description:
The proposed technology is applicable in the food industry, biotech industry and environmental area mainly for:
- In Biotech Application - opening biological cells, to harvest bio-molecules like protein etc.
- In Industrial Application – the disinfection of soluble oil or raw milk
- In Environmental Application – the treatment of waste water.
Problems addressed:
In some situations it is very hard to rapidly get down COD/DOC (Chemical Oxygen Demand/Dissolved Organic Carbon) levels to be able to recycle
water.
For instance in food industry the washing process of vegetables or moreover the reuse of water in a process, are asking for biological cleared water in
drinking water quality – if possible in real time. This generates large volumes to clear in wastewater plants taking days to complete the clearing process.
In biotechnology when enrichment broth/fermentation broth are used to harvest protein or plasmid-DNA, microbial cells are broken up (cell disruption).
Because the numbers of microbes are high 10e12 cells in a fermentation vessel – they need a lot of nutrition. This causes a high COD-level which is in
the range of 120´000 to 130´000 mg/l. There is currently no method known to reduce the COD-level in real time or nearly in real time.
Then a COD reduction needs to be done after the processes to reduce the COD-Level down to acceptable values to be able to let this water flow into
public water. It might also be needed to remove other organic material solved in the water (TOC/AOX -Total organic halides/adsorbable organic
halides).
To solve those problems reverse osmosis (RO) is not directly applicable because of high particle load. In addition to this, RO needs huge installations of
tanks / containers and pumps as well as tubes and machines which mean a high investment.
The Swiss company technology on the contrary is able to inactivate microbes in real time by leading the water through a number of cells (reaction
chambers) using an advanced flow electrolysis system where at the end of the process the COD is reduced and microbes are killed.
The process can be controlled by different parameters (mA/cm2; V ; C/ml; conductance; temperature; redox-level in mV; pH and COD-level on-line
measurement) using a micro-processor.
The potential of the technology is to handle any fluid (water based) to inactivate high levels of microbes (for e.g. 10e10 cfu /ml) in seconds to minutes
not hours. Large process equipment in stainless steel like heat exchangers etc. can be replaced saving space for installation and high investments
costs.
Using high power as a special application it could oxidize unwanted organic matter like pesticides, hormones and drugs out of the water to form
H20/CO2.
The company has a recognized deep knowledge and know-how of microbiology applications for contamination monitoring/detection and contamination
prevention and is collaborating with big companies and laboratories for a long time (for e.g. one of Switzerland's largest retailing company, owning
several production sites).

Innovative Aspects:
The innovation is designed to get a simple non expensive technology – with low running cost – applicable in the main fields of food technology.
- It is proven to inactivate most virus and phages as well as bacteria, yeast, fungi and spores. It is documented by the company that the technology will
also kill off any resistant germs. It forms out of water different radicals where for e.g. OH*-radicals are known to be the strongest oxidants. Electrolysis
alone does not give such performances(in terms of power and speed) in killing microbes or reducing COD/DOC values.
- The technology is a dynamic method also to handle large (1 to 10e4 m3) volumes of liquids.
- It is an energy saving method. The energy which is used in case of heating milk up to 130° C and cooling it down in traditional UHT-process is huge.
For pasteurized milk to go up to 80°C means the same. The Swiss company method does not require heating the liquid and can be done at
room-temperature. In the case of milk, milk can be bottled aseptically directly.
- The space needed for the new device is less than 1/10 in square meters of a traditional industrial device. It could be fitted as in row or in parallel
operation, depending on the volumes needed to be treated.
- None of the traditional methods such as Advanced Oxidation Process (AOP) for water, Heat transfer for milk are able to provide such results in
continuous flow operation mode with that speed and quantity/quality.

Target partner expertise sought:
- Type of partner sought: Middle size industrial company
- Specific area of activity of the partner: Company who is active in the food market or milk market. Company who is dealing with soluble oil.
Company who is active in the environmental market – water clearing.
Company who is active in Biotechnology – for cell disruption
Company who is active in medical nutrition market
- Task to be performed by the partner sought: technology license (manufacturing, furtehr commercialization) is sought.
