Characteristics of brining wastewater
Brining water becomes turbid and malodorous as the
brining steps are repeated, because of the accumulation
of debris of raw materials and growth of microorganisms.
As shown in Table 1, total organic carbon
(TOC) and the turbidity of the brining wastewater used
five times were much higher than those of fresh brining
water. Therefore, the major components to be removed
prior to the reuse of brining wastewater were thought to
be the dissolved and suspended organic matters such as
the debris of vegetables generated and microorganisms
grown and their metabolites produced in the brining process.
In this context, the brining wastewater reuse system
was designed to effectively remove such organic matters.
On the other hand, inorganic constituents in the brining
wastewater, such as calcium and magnesium, were
intended to be kept as much as possible even after the
treatment as these are known to play a key role in
inducing the delicate taste of Kimchi.
