  • Patent number: 10844331
    Abstract: Phosphorus-free detergent compositions are provided. Detergent compositions including an aminocarboxylate, water conditioning agent, source of alkalinity and water beneficially do not require the use of additional surfactants and/or polymers to provide suitable detergency and prevent scale build-up on treated surfaces.

  • Patent number: 10787631
    Abstract: The invention combines chemical cleaning with mechanical cleaning. In case of large scale facilities, the invention allows cleaning from bottom to top which obviates the need for special arrangements such as confined space entry scaffolding and safety nets removal in order to reach higher or inner parts. The dual effect of the combined mechanical and chemical cleaning facilitates a surprising efficient removal of organic and inorganic sediments. The chemical cleaning is achieved by a reaction of cleaning chemicals with the organic matter such as: oils, greases, hydrocarbons, cellulose. The implementation of the invention permits use of non-toxic, non-hazardous, environmental friendly mixture of sodium carbonate and sodium bicarbonate. Typical particle size of the thin powder used according to a preferred embodiment of the present invention shall be between 20-100 ?m.
