Abstract:
A bioremediation product for use in the biodegradation of liquid hydrocarbons in an environment containing microorganisms which have an affinity for consuming and thereby decomposing liquid hydrocarbons. The bioremediation product comprises a mixture a sphagnum peat moss (32) which absorbs the hydrocarbons and a nutrient solution for providing nutrition for the microorganisms. The nutrient solution includes a culture of microorganisms which have an affinity for consuming the hydrocarbons. The invention extends to a method of biodegrading liquid hydrocarbons by mixing the bioremediation product together with the liquid hydrocarbon to be treated, into soil in a soil landfill and allowing time for microorganisms occurring naturally in the soil to consume and thereby decompose the hydrocarbon. The invention extends also to method of producing the bioremediation product by spraying the nutrient solution through spray nozzles (29) onto the moss.
Abstract:
A drying apparatus (10) for drying sphagnum moss comprises a rotatable drum (12) in which moss to be dried is supported and two rows of infrared lamps (14) which are located in the drum for heating the moss. The drum (12) has a first end (20) defining an entrance opening (24) through which moss is introduced into the drum and a second end (22) defining a discharge opening (26) through which moss is discharged. The drum (12) includes a number of curved vanes which act on the moss as the drum rotates thereby to cause it to be displaced from the first end 20 to the second end (22). As the drum rotates, the moss is turned over allowing for effective heating of all sides of the moss. The lamps (14) provide for contact-less directional heat transfer to the moss so as to cause evaporation of moisture therefrom.
Abstract:
A filter press (10) for treating effluent water, comprises a press frame (12) including two support beams (14), a front end plate (18), a rear end plate (22). The press (10) includes six filter plates (26) that are moveably supported on the beams (14). The press (10) includes a pressing plate (34) and a piston/cylinder mechanism (28) which exerts a force on the pressing plate (34) for displacing the filter plates into a closed compressed condition. Each filter plate has a central inlet port for effluent water and four peripheral outlet ports for filtered water; and a pair of electrically-conductive filter screens located between the filter ports for filtering contaminants from effluent water. A layer of sphagnum moss which serves as a filter medium is located on the filter screens. The press (10) includes an electrical connector coupled to the filter screens and connectable to an electrical power source for applying an electrical charge to the filter screens and the sphagnum moss.
