Coagulation of Oil in Water Using Sawdust and Bentonite and the Formation of a Floating Coagulated Material
The coagulation of oil in water is potentially cost-effective for removing oil from water. A coagulant consisting of sawdust (79.6% by volume), bentonite (15.8% by volume), and calcium hydroxide (4.7% by volume) gives coagulation efficiency of ≥94% and coagulation time of ≤ 45 s. The resulting coagulated material (a semisolid) floats on water. Its oil (liquid) content, which decreases with a de...

Soilless culture in greenhouse is being developed in Iran, as in many countries of the world. This study was conducted to evaluate the possibility of applying sawdust as well as the effect of adding bentonite and pumice on vegetative growth of bell pepper cv. Inspratian. The experiment was conducted as a completely randomized blocks design with 8 treatments and 4 replications, in greenhouse of ...
متن کاملBioremediation of gasoil by indigenous bacterial strains
Petroleum refining industries produce large amounts of toxic effluents, causing environmental pollution. Iran is an oil-rich country that encounters oil pollution in its soil and water. Bioremediation of these pollutants is an appropriate solution to tackle them, compared to physical and chemical remediation methods. There are some factors that increase the rate of biodegradation; therefore, th...
