Rezumat
Dezvoltarea sistemului de colectare si tratare a apei uzate in Romania ca rezultat al Tratatului de
Aderare va duce la cresteri tot mai mari a cantitatilor de namol. Astfel o crestere aproximativa de 5 ori a
cantitatii de namol va rezulta in urma tratarii pana in anul 2020, cand toate localitatile cu peste 2,000 de
locuitori trebuie sa aiba retele de canalizare si trebuie sa fie conectate la o statie de epurare care include si o
linie de precesare a namolului. Tratamentul namolului este o necesitate inainte de a fi eliminat pentru
depozitare sau valorificare ulterioara. Scopul tratarii este de a reduce sau elimina potentialul de descompunere
si mirosurile neplacute precum si de a reduce continutul de apa. Operatorii din statiile de epurare
trebuie sa identifice cele nai bune solutii si practici de mediu pentru tratarea, valorificarea/eliminarea
namolului, ambele sustenabile si eficiente din punct de vedere al costurilor.

Abstract
The development of the wastewater collection and treatment in Romania, as a result of the
Adhesion Treaty, will lead to the production of higher and higher sludge quantities. Thus, an approximate
increase of five times of the sludge quantity will result after treatment, by the year 2020, when all the
localities over 2000 inhabitants should have sewerage networks and should be connected to a wastewater
treatment plant which includes a sludge processing line. The treatment of the sludge is a necessity before
being removed for storage or subsequent recovery. Purpose of treatment is to reduce or to eliminate potential
decay and bad odours, as well to reduce the water content. The operators of the waste water treatment plants
must identify the best environmental solutions and practices for the treatment, recovery/disposal of sludge,
both sustainable and efficient in terms of costs
