I-phenolic resin yenye yezinto ezibalulekileyo kumashishini afana ne-brake pads kunye ne-abrasives. Amanzi amdaka avelisiweyo ngexesha lokuveliswa kwe-phenolic resin yingxaki enzima kubavelisi.

Amanzi amdaka emveliso ye-phenolic resin iqulethe i-phenols ephezulu, i-aldehydes, i-resins kunye nezinye izinto eziphilayo, kwaye ineempawu ze-organic concentration, i-toxicity ephezulu, kunye ne-pH ephantsi. Zininzi iindlela zokusetyenzwa zokunyanga amanzi amdaka ane-phenol, kwaye iindlela ezisetyenziswa kakhulu ziquka iindlela ze-biochemical, iindlela ze-chemical oxidation, iindlela zokukhupha, iindlela zokubhengezwa, kunye neendlela zokuhluthwa kwegesi.
 
Kwiminyaka yakutshanje, kuye kwavela iindlela ezininzi ezintsha, ezifana ne-catalytic oxidation method, indlela yokwahlula inwebu yolwelo, njl.njl., kodwa kwiiprojekthi zokonyango lwamanzi amdaka ephenolic resin, ngakumbi ukuze kuhlangatyezwane nemigangatho yokukhupha, iindlela ze-biochemical ziseyeyona ndlela iqhelekileyo. Umzekelo, le ndlela ilandelayo ye-phenolic resin yokucoca amanzi amdaka.
Okokuqala, qhuba unyango lwe-condensation kumanzi amdaka e-phenolic resin, ukhuphe kwaye ubuyisele i-resin kuyo. Emva koko, iikhemikhali kunye ne-catalysts zongezwa kwi-phenolic resin wastewater emva konyango oluphambili lwe-condensation, kwaye unyango lwesibini lwe-condensation lwenziwa ukususa i-phenol kunye ne-formaldehyde.

Amanzi amdaka e-phenolic resin emva kokuba unyango lwesibini lwe-condensation luxutywe kunye nempompo yamanzi amdaka, ixabiso le-pH lilungelelaniswe kwi-7-8, kwaye livunyelwe ukuma. Emva koko qhubeka ukongeza i-ClO2 kwi-catalytically oxidize amanzi amdaka ukuze unciphise ngakumbi umxholo we-formaldehyde kunye ne-COD. Emva koko yongeza i-FeSO4, kwaye ulungelelanise ixabiso le-pH kwi-8-9 ukususa i-ClO2 eziswa yisinyathelo sangaphambili.
Amanzi amdaka e-phenolic resin aphethwe kwangaphambili aya kufakwa kwi-SBR yonyango lwe-biochemical ukususa ukungcola emanzini ngokusebenzisa i-microorganisms.
Amanzi amdaka emveliso ye-phenolic resin aphathwa kwangaphambili kuqala, aze ahlaziywe, ukuze amanzi amdaka afikelele kumgangatho.
