The use of advanced oxidation methods, including sonocatalytic processes, in order to purify water and wastewater (disinfection and decomposition of hazardous organic pollutants) has been extended across the world as replacement for traditional oxidation methods such as chlorination and ozonation
Deputy Director, PSQCA, Waiz Akram Ul Haq, on the occasion said the water is purified in 11 stages and these include Chlorination, Sand Filtration, Activated Carbon Filtration, Fine Filtration, Microfiltration, Second Pass RO, Mineralisation, Ozonation
and UV Sterilisation.
Persistent organic substances dissolved in industrial wastewater discharged from various types of production facilities must be treated before reuse, but conventional water treatment methods, such as chlorination or ozonation
, are usually ineffective.
" These impurities are not present in raw water but are formed due to the process of ozonation
used for treatment of water.
This study concluded that ozonation
was an efficient method for the treatment of textile washing and rinsing wastewater.

This paper presents details of an innovative ozonation
duct system which employs ozone producing lamps as an ozone source to exam the ozonation
performance under the conditions relevant to the actual applications.
Disintegration techniques including ultrasound , gamma irradiation , ozonation
, enzyme  and combination of alkaline and high pressure homogenizer  have been studied to enhance sludge biodegradability.
Cryptosporidium microorganisms are chlorine-resistant and can be filtered and disinfected through microfiltration, ozonation
and UV disinfection.
Bromate (Br[O.sub.3.sup.-] anion) is a disinfection by-product (DBP) which is formed during the ozonation
process of bromide containing waters.
The performances of removal and mineralization of toluene were examined under different conditions with photolysis by HFDEL, Mn[O.sub.2]-impregnated GAC-mediated catalyzed ozonation
, and the combination of HFDEL and Mn[O.sub.2]-impregnated GAC.
