Sidaa darteed, ma jiro hab daawayn oo bislaaday oo midaysan oo loogu talagalay biyaha wasakhda ah ee dawooyinka. Dariiqa habka loo dooranayo waxay ku xiran tahay biyaha wasakhda ah. dabeecadda. Marka loo eego sifooyinka biyaha wasakhda ah, pretreatment ayaa guud ahaan loo baahan yahay si loo hagaajiyo biodegradability ee biyaha wasakhda ah, marka hore laga saaro wasakhda, ka dibna lagu daro daaweynta biochemical. Waqtigan xaadirka ah, horumarinta qalab daaweyn oo isku dhafan oo dhaqaale iyo waxtar leh waa dhibaato degdeg ah oo la xalliyo.
