Due to the requirements from the Authority of Contamination Control in
Ensenada, Baja California, to dispose of our liquid residues to the
industrial drainage, and being a company dedicated to produce flour,
oil and concentrated fish soluble, we had to implement different
methods or steps to remove solids from thick to fine in order to leave
water completely translucent.
It is at this point that an existent portion of the process that
cannot be removed by conventional methods of filtration or
flocculation, because this portion of the product is so fine that is
specially difficult and it takes a long time to remove.
We decided to test zeolite from Safetysorb Zeolite, Inc. to assure
ourselves that the liquids we were sending out met the required norms
for the State Commission of Public Services of Ensenada.
The results obtained are as follow.
-
We were able to reduce 26% to 36% of the BOD and, as
mentioned above, it is highly difficult to lower this parameter. As it
is known, the more you process any liquid, the percentage of reduction
is lower if you maintain the other variables.
Along with obtaining the parameters requested by
conventional discharge methods the reason for testing this mineral is
to try and obtain a quality of water that can be reused for mere
industrial purposes.
As the responsible person for disposal of residues, both liquids and
solids for this company and from my professional point of view I can
recommend the use of this mineral from Safetysorb Zeolite Inc. for
treatment of residual waters for reuse and recycling. |
