Clarification and Flotation


The effluent to be treated passes through the screening area where the solids and/or foams are captured clogging partially the screen surface with consequent increase of water level in the channel.
Screening and Separation


To separate colloidal suspensions and oily emulsions under satisfactory speed conditions (for example under the influence of weight in the sedimentation or clariflocculation step or under dissolved air influence in the flotation), it is necessary to respectively unify the colloids to form bigger particles and to break the emulsions.
Screening and Separation


Idrapress™ has been designed for the conveyance and dewatering of various types of wastewater screenings and it is capable to reduce drastically the screenings weight and volume and consequently transport and disposal costs.
Screening and Separation


To separate solids from process and drainage water has always been a serious problem often difficult to solve in many industrial sectors and wastewater treatment plants.
