  • Patent number: 7771504
    Abstract: The present invention relates to methods and apparatuses for the production of organic liquid fertilizer from waste using a two-phase process. The first phase comprises a successive extraction process whereby liquid leachate is drained from one plant or storage container and the process subsequently re-started with new fresh water. The second phase comprises an accelerated bio-leaching process wherein plant material is stored in a solid bed similar to a batch process, and a leachate (e.g., water and bacteria) is re-circulated through the solid bed until the process of hydrolysis and acidification results in dissolution of organic material into the re-circulating leachate. The leachate is thus concentrated without losing the nutrient and is subsequently used as an organic fertilizer.

  • Publication number: 20090320552
    Abstract: The present invention relates to methods and apparatuses for measuring flow rate in pipes. The standard method of installing flow meters inside pipes to measure flow rates are costly and result in loss of energy and reduction of flow. The present invention solves the problems of standard flow measuring method. The present invention uses an apparatuses comprising of a first pipe and a by-pass second pipe. The flow is partitioned between the first pipe and the by-pass second pipe. A flow meter is installed in the by-pass second pipe. The flow rate is measured through the by-pass second pipe, and using the by-pass second pipe flow rate, the combined flow rate through the first pipe and the by-pass second pipe is calculated. The invention describes two methods to calibrate the apparatuses and relate the flow rate in the by-pass second pipe to total combined flow rate.
