THE INTEGRATION OF SLUDGE FROM WASTEWATER TREATMENT PLANT IN THE ENVIRONMENT
Journal Title: Natural Resources and Sustainable Development - Year 2015, Vol 5, Issue 1
Abstract
The objective of the research consists in the study of germination capacity of Opal pepper variety under the influence of sludge coming from the water treatment plant in Oradea and determining the optimum mixture rates for maximum efficiency. The specific analyzes showed that the sludge taken in the study comply with existing laws in force in our country (Order no. 344/2004). For to establish germination capacity based on optimal quality irrigation water, and experience two factors curprins: Factor A - the variety Opal; Factor B - sludge graduations: B1 sludge wastewater treatment plant; B2 blend 25% sludge and 75% organic soil; B3 with 50% sludge and 50% organic soil; B4 blend 75% sludge and 25% organic soil; B5 organic soil. The greatest germination capacity is observed in samples that had in the study the mix 75% sludge - 25% soil and sludge from the water treatment plant (100%). Relating to the time of germination was found that most seedlings were obtained for the situation when we used sludge 100%. The highest number of seedlings at the end of the study was obtained for the group in which we only used sludge, respectively, mix 75% sludge - 25% (5 seedlings), compared to the group that used only soil were obtained two seedlings
