Abstract: A logistics system includes a first high-bay rack, at least one further high-bay rack, and at least one robot arm with a plurality of links and joints connecting the links for relative adjustment. One of the links is a bottom link of the robot arm which forms a base. The first high-bay rack has a first robot arm carrier with a first coupling device which, in a state in which the robot arm is coupled to the first robot arm carrier, interacts with a counter-coupling device of the bottom link of the robot arm in such a way that, in a first configuration of the logistics system, the bottom link of the robot arm is connected to the first robot arm carrier in an automatically locked and automatically releasable manner.

Abstract: A method for cleaning and maintaining reverse osmosis membrane filters by injecting sulfurous acid into water to form sulfurous acid (H2SO3), and then sequentially filtering the acidified water through membrane filters to reduce alkalinity and mineral scaling, add sufficient SO2 as a biocide to attack bacteria and other micro organisms to prevent membrane fouling, reduce iron to prevent iron deposit build-up, scavenge and remove dissolved oxygen prior to filtration to prevent membrane oxidation, and prevent concentrated salts within the retentate from precipitating out of solution during transport for land application.

Abstract: A pre-treatment method for cleaning and maintaining reverse osmosis membrane filters by injecting sulfurous acid into waters with suspended solids in a liquid fraction to be filtered to form sulfurous acid (H2SO3) to acid leach heavy metals into the liquid fraction, reduce alkalinity and mineral scaling, add sufficient SO2 as a biocide to attack bacteria and other micro organisms to prevent membrane fouling, reduce iron to prevent iron deposit build-up, scavenge and remove dissolved oxygen prior to filtration to prevent membrane oxidation, and then sequentially filtering the acidified water through membrane filters to create a metal free permeate and a brine retentate, which can be pH adjusted to remove the heavy metals as metal hydroxide precipitates.

Abstract: A chemical/biological wastewater treatment plant apparatus and treatment method employing rapid sludge chemical dewatering technology in conjunction with an environmental biological system for treating the separated treated wastewater by land applying it for the propagation of biosynthetic fuels and other plants; and/or passing it through aqueous plant or microbial reduction of the dissolved solids and ammonia for BOD compliance to produce water of sufficient quality to reduce the overall salt load currently being added by wastewater treatment facilities into natural waterways, and to produce water of sufficient quality to meet open stream and ocean effluent discharge requirements; and disposing of the high BTU low moisture solids.
