In statiile de epurare, apele uzate menajere sunt supuse mai multor etape, de eliminare mecanica, biologica sau chimica a suspensiilor, nisipului, poluantilor toxici, grasimilor, apoi sunt separate prin decantare de namolul rezultat. Namolurile in exces trebuie inlaturate pentru ca procesele bio-chimice sa poata fi controlate eficient, eliminarea facandu-se prin stabilizare si prelucrare prin ingrosare/deshidratare. Prelucrarea prin ingrosare/deshidratare a namolurilor de epurare se realizeaza prin adaosul de agenti de floculare - polielectroliti care favorizeaza procesele de concentrare si deshidratare, actionand asupra particulelor solide din namol, prin neutralizarea sarcinii electrice a acestora si prin formarea de flocoane cu proprietati de deshidratare imbunatatite.
