Abstract: A method of filtering tannery wastewater includes micro filtering a wastewater input of wastewater in at least one micro-filter, thereby splitting the wastewater input into a first retentate stream which includes organic compounds and a first permeate stream. The method further includes establishing, on the basis of the first permeate stream or a derivative thereof, a reverse osmosis input stream. The method further includes performing, on the basis of reverse osmosis input stream, a reverse osmosis filtering by a reverse osmosis filter, thereby establishing a reverse osmosis retentate stream and a reverse osmosis permeate stream. The wastewater includes one or more side streams of a tanning process.

Abstract: An apparatus includes a process chamber, a controllable compressor for pressurizing a fluid, a pressure reducing member, an inlet for a processing agent and a controller. The process chamber is a pressure chamber. The controllable compressor pressurizes a fluid and introduces the pressurized fluid into the process chamber from a source. Further the controllable compressor controls a predefined pressure in the process chamber to reach a supercritical state of the fluid. An inlet for a processing agent facilitates introduction of the processing agent into the process chamber prior to, during, or subsequent to pressurization of the fluid. The pressure reducing member reduces the pressure of the fluid at least to reach a gaseous state subsequent to processing the leather object such that the time for reduction of pressure exceeds a predefined reduction period or the reduction of pressure does not exceed a predefined leather pressure reduction gradient.

Abstract: A tanning process for tanning of animal hides in a process equipment including a tanning container, a controller, and temperature regulating equipment. The controller controls the temperature in the tanning container based on a temperature setpoint input to or established by the controller. The tanning process includes the steps of initially determining process parameters based on animal hide characteristics including at least animal hide type and animal hide weight. The process parameters include at least one of the parameters: time, temperature, start pH and end pH or any combination thereof. The tanning process of the animals hides is executed based on the process parameters in the tanning container under atmospheric pressure. The tanning process involves the addition of tanning agents to animal hides in the tanning container. The tanning involves the addition of water in an amount of less than 10% bw of the animal hides.
