摘要：The study evaluated the content of hydrophobic and
hydrophilic organic substances in water subjected to purification in the
technological system: coagulation, filtration on anthracite-sand deposits
and biofiltration on granular activated carbons. The estimation of the
removal efficiency of individual NOM fractions was made on the basis of
fractionation method using polymeric resins (DAX-8, XAD-4 and IRA958).
The obtained results allowed to state that the applied water treatment
system is effective in removing organic matter and its effectiveness in
relation to individual parameters was: 55% for total organic carbon (TOC),
49% for dissolved organic carbon (DOC), 80% for particulate organic
carbon (POC), 68% for UV absorbance, 83% for permanganate value and
100% for colour. In the intaken groundwater, the value of the hydrophobic
fraction was 84%. The dominant fraction was very hydrophobic acid
(VHA), whose content was 4.87 mg C/L (65% DOC). On the grounds of
the information on the content of the NOM fraction in the intaken waters,
the effectiveness of their removal in the unit processes of the technological
system cannot be unequivocally determined. The content of NOM fractions
established on the basis of the fractionation procedure and the SUVA
parameter does not give explicit results. Further research should be carried
out in this respect.
