OSSAMONIO® PQA PLUS is a blend of polymeric quaternary ammonium compounds, based on Polyquaternium-42 and poly-N,N-dimethyl-2-hydroxypropyl ammonium, formulated as a viscous amber liquid. It is characterized by combining biocidal properties with coagulating capacity, making it a multifunctional solution for water treatment.

It stands out for its broad-spectrum algaecidal and bactericidal action, as well as its ability to act as a coagulant and clarifying agent in aqueous systems, promoting the agglomeration and removal of colloidal particles. Its polymeric nature provides greater persistence and efficiency compared to conventional low molecular weight biocides.
