TITLE:

Microalgae growth in Foto-Fenton-treated landfill leachate.

KEY WORDS:

microalgae. Landfill, Photo-Fenton.

SUMMARY:

The landfills generate liquid and gas subproducts that require treatment before being disposed. The liquid generate are the leachate, and this liquid is characterized by the dark color and high concentration of organic matter. Despite these characteristics it’s possible to use the leachate as resource in other process, as the nitrogen recovery. This study is about an investigation about the growth of microalgae using the leachate treated by photo-Fenton process. The leachate was collected at Aterro Metropolitano Centro (AMC), at Salvador Bahia, and treated by photo-Fenton process to reduce the organic matter concentration. To optimize the treatment, the design of experiments was used. The COD and true color on the optimize treatment achieve the reduction of 75,5% and 95,3%, respectively. This treated effluent was used for microalgae cultivation. After a brief adaptation stage of the species Euglena gracilis and Chlorella vulgaris the experiment continued with the monitoring growth for 21 days, using the counting for analyze the growth. After this cultivation a new one was started but some conditions were adapted as the light intensity. Using this last experiment was possible to concluded that Euglena gracilis have growth potential in treated leachate and Chlorella vulgaris had the best growth using the treated leachate with high light intensity and aeration.
