    摘要: A process for treating sulphate containing effluent, which includes receiving a sulphide containing effluent into a two-phase fluidised bed reactor containing particles and floating media, permitting calcium carbonate from the effluent to precipitate on particles in the first fluidised bed reactor, aerating the solution in the reactor to remove CO2 from the solution, thereby to increase the pH in the reactor, permitting biological sulphide oxidation to occur on the floating media by means of sulphide oxidizing bacteria thereby to produce elemental sulphur, recycling the fluidised bed reactor at a sufficient rate to effect abrasion to remove elemental sulphur from the floating media, harvesting the sulphur from a top portion of the reactor, recycling hydroxyl ions internally in solution in to enhance calcium carbonate precipitation by further increasing the pH.

    摘要: A method for clarification of wastewater that operates at least two alternating and equal process cycles in two or more clarifiers (1a, 1b), each process cycle consisting of a feed period with concurrent feeding and discharging and a reset period in which excess sludge is removed into a thickener (2a, 2b) and the remaining sludge blanket gets homogenized and pre-settled, wherein at each point of time in at least one clarifier (1a, 1b) the feed period is performed.

    摘要: A bioreactor has a biofilm supporting bed 20 with at least two types of media. An upper media is relatively porous, preferably porous enough to admit particles of a lower media. In use, wastewater 18 flows downwards through the bed. Soluble nitrogen is reduced in the upper media and converted into nitrogen gas. Nitrogen gas bubbles rise through the upper media and escape from the bed. Selenium is reduced in the lower media and converted into elemental selenium. The elemental selenium is released periodically by backwashing the bed, which may cause fluidization or other expansion of the lower media into the upper media.

    摘要: The invention relates to a method for the solid/liquid separation of suspensions containing microalgae, wherein biodegradable materials are used as a filter material. The method comprises the following steps: First, a filter layer made of organic material is introduced into a filter device. Then at least one application of the suspension to be separated to the filter layer is performed, wherein the solid constituents of the suspension are deposited on the filter layer and the liquid constituent passes through the filter layer as filtrate. The solid constituents of the suspension comprise microalgae, wherein subsequently the filter material and the microalgae are hydrolyzed by microorganisms naturally contained in the filter material or added separately. For the hydrolysis, it is important that the filter layer be kept moist in order to prevent the microalgae from drying out. In addition, valuable substances (dyes, lipids, proteins) can be extracted from the filtrate. The filtrate can also be used to produce biogas in a methane reactor. The filter material that is not biodegradable or is difficult to biodegrade can be used as organic compost. The waste liquor from the methane reactor can be used again for microalgae cultivation after decontamination.
