Technical authorizations : If the corresponding authorizations are not available at the time of pre-award, these may be processed later, but they must be valid before the purchase order is issued. Importance of PAC in water treatment Polyaluminium chloride (PAC) is an essential coagulant for the purification and wastewater treatment processes at AySAs three main plants: General San Martín (CABA), General Belgrano (Quilmes) and Juan Manuel de Rosas (Tigre). During the coagulation process, PAC binds contaminating particles and transforms them into flocs, facilitating their sedimentation and separation from the water. This procedure is key to reducing turbidity and eliminating microorganisms, guaranteeing quality water for millions of users. Promoting innovation and transparency With this international tender, AySA seeks not only to guarantee a fair process, but also to encourage bidders to present innovative and high-quality solutions for the operation of the plant. The initiative aims to strengthen the water treatment service, promoting sustainability and continuous improvement in its operations.
