Our ChitoVan™ process coupled with our laboratory expertise is completely adaptable to any water quality problem you may experience now or over
time as needs change.
As a passive process ChitoVan™ can be installed quickly enabling you to setup and begin capturing contaminates immediately.
As a true passive treatment, ChitoVan™ requires very little equipment and no external energy source. It is easy to install and maintain
and is very flexible. Most necessary treatment elements are already in place or available on many construction sites. Just add the
ChitoVan™ cartridge process in the most appropriate location and monitor its performance. With a little planning this method is
capable of consistently reducing water turbidity by greater than 90%.
The passive ChitoVan treatment process is best suited for sites that have concentrated flow, adequately sized settling ponds and a natural
vegetated area for filtration.
Example of Passive Treatment with ChitoVan™
Our ChitoVan™ process is also well suited to either semi-passive or active treatment as well. Technically, the difference between semi-passive
and passive is small. Semi-passive treatment simply utilizes external energy (ie: a pump) to move water. Like passive treatment, semi-passive
treatment is inexpensive, easy to install and easy to maintain. Both passive and semi-passive treatment is accomplished with our ChitoVan™
chitosan lactate cartridge, cartridge applicator, settling basin and natural filtration. ChitoVan™ semi-passive treatment is suited for a
wider range of projects because it can be accomplished with a smaller footprint and allows for more versatility.
With a little planning and correct installation, semi-passive treatment using our ChitoVan™ process is capable of consistently reducing water
turbidity by greater than 95%.
ChitoVan™ can also be easily adapted to full active treatment. A more aggressive approach to water treatment, requiring significantly more equipment
to archive turbidity reduction, the ChitoVan™ process utilizes chitosan (typically in its liquid acetate form) to flocculate solids. The floc then
can be separated from water by gravity settling and pressurized sand filtration. Active treatment is highly effective at removing suspended solids
and typically achieves a turbidity reduction of greater than 99%.
Example of Active Treatment with ChitoVan™
Whichever process suits your needs, you can expect at least 90% turbidity reduction (passive treatments) and up to over 99% reduction
for a full active system. That is efficiency. Coupled with our custom laboratory enhancements of the ChitoVan™ processes, even greater
efficiencies are available to you.
Any DESI ChitoVan™ process from a strictly passive system to an active facility is more efficient per percentage of turbidity decrease
per dollar than most any other method today.
Our ChitoVan™ process uses chitosan lactate, a naturally derived biopolymer that in the past was considered nuisance waste in seafood
processing. Since chitosan is derived directly from nature and considered waste, it stands to reason that its reuse in this higher
form is as kind to the environment as any form of filtration can be.
