Composition of Detergent and Chloride in Tunisian Textile Sludge and Produced Composts as a Function of Sludge Ratio

Mohamed Anis El Hammadi, Melika Trabelsi and Belgacem Hanchi    

Abstract: The present research attempts to ascertain the efficacy of low cost technology (in our case, composting) as a bioremediation technique for reducing detergent and chlore content of textile sludge in semiarid conditions. The sludge was produced in a textile manifacture in the north of Tunisia. The composting system designed involved two parallel open air piles turned periodically over a period of 3-months. Textile sludge was co-composted with greenwaste at (1:1 v/v (compost C1) and 1:3 v/v (compost C2) ratio. In C1, the detregent and chlore contents was reduced respectively by 95,19 and 96.35% in 3 months, compared with the 86.66% efficacy reduction content of chlore in C1 and the increase by 46.34% in C2. The degree of xenobiotics in the first mixture and after composting in C1 was influenced by the introduction of higher sludge ratio. Results from this study demonstrate that co-composting textile sludge with greenwaste may provide an inexpensive and reliable technology for the biodegradation of sludge toxic compounds for further agriculture use.
