  • Machine dish-washing process
    Publication number: 20060090775
    Abstract: Machine dish washing process is invented wherein a detergent is supplied from a storage supply and is dispersed from at least one nozzle over crockery within the dish washing machine such that said crockery is washed with said detergent and said detergent is removed from said crockery thereafter, wherein said detergent is dispersed in a pulsating manner, e.g. said detergent leaves the nozzle as a pulsating flow. Preferably said pulse frequency is below 15 Hz, and during a single pulsating cycle, the dispensing rate changes e.g. from zero to maximum and back to zero.

  • Machine dish-washing process
    Patent number: 6176244
    Abstract: A machine dish washing process wherein a detergent is given such a composition and/or is dispersed over the crockery in such a way that with the detergent a cleaning layer with an appearance distinct from water is formed on preferably at least substantially the complete surface of the crockery, which distinction preferably can be discerned by the naked eye.

  • Machine dish-washing process
    Patent number: 5772785
    Abstract: Dish-washing process, in which a solid cleaning composition in powder form is distributed over crockery in such a manner that the surface of the crockery is completely or partially covered with the cleaning composition, and said powder-form cleaning composition, after distribution, is given an operational form, for example by means of contact with a solvent. The powder is preferably dispersed over crockery which has been moistened with water.

  • Method for processing a liquid nitrogen rich organic waste product, thereby obtained fertilizer solution and use thereof
    Patent number: 5656059
    Abstract: A method for processing a liquid nitrogen-rich organic waste product, in particular a manure product, to an aqueous fertilizer solution utilizes a biological conversion process so as to obtain a biologically stable fertilizer solution. This conversion process includes at least a nitrification step wherein nitrifiable ammonium nitrogen is converted in nitrate nitrogen and, only if the fraction to be nitrified has a too high content of nitrifiable nitrogen, a denitrification step. The fertilizer solution is separated off after the nitrification step so that it contains nitrate and only up to 150 mg NH.sub.4.sup.+ -N/l at most. The fertilizer solution can be used as leaf nutrition or in a hydroponic system.
