USING HYDRODYNAMIC CAVITATION TO REDUCE PARTICLE SIZES AND DISTRUPT LIGNIN IN FEEDSTOCKS AND SUBSTRATES
We have a proven technology to distrupt the lignin in straw and grass, which we know is the key to utilising these plentiful and lower cost feedstocks. There are a couple of existing processes capable of doing this, such as steam and alkali treatment. However, we have an innovative and clever machine that harnesses the power of hydrodynamic cavitation.
The E-PIC S.r.l ROTOCAV in the CaviMax makes all this possible by producing physical rotational forces that create hydrodynamic shockwaves, breaking down seemingly incompatible gas/liquid/solid mixtures into flowing substrates.
The shockwaves induced by a liquid moving from a high to low to high pressure environment, causes millions of microscopic bubbles to form and then collapse, creating tremendous localised pressures, which shear solid particles, break down cell walls and allow liquids to bind with solids, or gases to liquids. For the biogas industry this means that a substrate is created with a greater surface area, which is more readily available to be broken down by the anaerobic digestion bacteria, this in turn means more biogas...quicker.
So, in short theCaviMax cavitator is a process intensification device which increases sustainability ratings, lowers carbon footprints, provides flexibility in the running of your plant and can increase your biogas yield.
Below is a list of features and benefits of cavitation to the biogas industry.
