 Abstract
The experiment was carried out in order to establish, at laboratory level, the effect of iron ions over the composition and performances of an active slurry used for biological treatment of waste water in petrochemical industry. A proximity effect of steel walls can be observed from the experimental results. This leads to the reduction of cleaning efficiency and increase of speed sedimentation for the studied slurry.

 Rezumat
Experimentul s-a efectuat pentru a se stabili, la nivel de laborator, rolului ionilor de fier asupra compozitiei si performantelor unui namol activ utilizat la epurarea biologica a apelor uzate provenite din industria petrochimica. Datele obtinute au pus in evidenta existenta unui efect de vecinatate al peretilor din otel, care duce la diminuarea eficientei epurarii si la cresterea vitezei de sedimentare pentru namolul studiat.
