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.
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.
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.
The Mectan™ vortex grit system is a circular chamber that takes full advantage of the tangential inflow velocity along the peripheral wall of the chamber to assist in the grit removal process.
The Rotarc™ brush fine screen is a monobloc screen with perforated stainless steel panels and nylon or polypropylene brushes for continuous cleaning. The screening openings can be of 6mm (1/4'') or 3mm (1/8'').
