Fish farming water treatment

When fish farming, it may be necessary to treat the fish, to control parasitic infections for example. The addition of active pharmaceutical ingredient (API) in the food or the water is frequently use. However, a part of those API can subsist in the water and have a negative impact on other living organisms. 

 

In order to address this issue, Seprosys has developed and patented a filtration method to reduce the concentration of API in water.

Sugar cane vinasses valorization

The fermentation of sucrose extracted from sugar cane is an important process for ethanol production. During this process, vinasse, an aqueous liquid containing salts and organic compounds by-product is formed. The current methods to eliminate the vinasses are to treat them as waste or to use them as fertilisers, raising doubts on their harmlessness for the soils and/or the groundwaters.  

 

In order to valorize those sub-products and not treat them as wastes, Seprosys has developed a process to extract the compounds of interest from sugar cane vinasses, like inositols and/or polyconasols.

=> This process using filtration, ion exclusion and affinity chromatography methods has been patented.

Extraction of sugar cane polycosanols

The fermentation of sucrose extracted from sugar cane is an important process for ethanol production. During this process, vinasse, an aqueous liquid containing salts and organic compounds by-product is formed. The current methods to eliminate the vinasses are to treat them as waste or to use them as fertilisers, raising doubts on their harmlessness for the soils and/or the groundwaters.  

 

Seprosys developed a method in order to extract the polyconasols from concentrated sugar cane vinasses whose organic compounds quantity is equal or above 35 g/L. The process involves ion exclusion chromatography, microfiltration concentration and affinity chromatography steps.

=> This process has been patented.
