This work evaluates the removal/degradation of lindane in water contaminated by agricultural activity. A test to treat lindane-contaminated water was carried out using four SF-CW systems operating simultaneously: two fed with lindane-enriched water (10 mg/L), and the other two fed with lindane-free water as control units. The monitored parameters were: average lindane-removal efficiency (η, %), COD, and BOD5, which were determined as 63, 43, and 52%, respectively. A correlation between the increase in dissolved oxygen (DO) concentration, and the increase in lindane degradation (10.58-0.91 mg/L) was observed. The average phosphate concentration (2.79 ± 1.07 mg/L) in the effluent was higher than the phosphate concentration plants can assimilate (0.5 mg/L), this lead us to believe there is an inhibition of the removal activity due to phosphate saturation in the system.
