Phenolic resin yana ɗaya daga cikin mahimman kayan albarkatun ƙasa a cikin masana'antu kamar su birki da abrasives. Ruwan sharar da aka samu yayin samar da resin phenolic matsala ce mai wahala ga masana'antun.

Samar da resin phenolic ruwan sha ya ƙunshi babban adadin phenols, aldehydes, resins da sauran sinadarai, kuma yana da halaye na babban taro na kwayoyin halitta, yawan guba, da ƙananan pH. Akwai hanyoyin sarrafawa da yawa don magance ruwan datti mai ɗauke da phenol, kuma hanyoyin da ake amfani da su sosai sun haɗa da hanyoyin biochemical, hanyoyin oxidation na sinadarai, hanyoyin hakowa, hanyoyin adsorption, da hanyoyin cire iskar gas.
 
A cikin 'yan shekarun nan, da yawa sababbin hanyoyin sun fito, irin su catalytic oxidation method, ruwa membrane separation method, da dai sauransu, amma a cikin ainihin phenolic guduro sharar gida ayyukan jiyya, musamman domin saduwa da fitarwa matsayin, biochemical hanyoyin ne har yanzu na al'ada hanya. Misali, hanyar maganin sharar ruwan guduro mai zuwa.
Da farko, gudanar da kula da magudanar ruwa a kan magudanar ruwan guduro na phenolic, cire da kuma dawo da guduro daga gare ta.
