  • Domestic scale vermicomposting for solid waste management

    Background;Vermicomposting has recently been recognized as one of the most appropriate methods to stabilize organic waste. In terms of a system for waste management, vermicomposting is sustainable, economically viable, and without detrimental effects to human health or to the environment. The aim of this study was to evaluate the process of vermicomposting using an indigenous species of ...

  • Solidification / Immobilisation of hazardous waste for subterranean storage

    The use of subterranean salt mines for the final storage of inorganic hazardous waste is state of the art in Germany, and in fact most other European countries. However, the technical requirements to prepare the waste in an appropriate way are quite challenging. Over ten years ago econ supplied a plant to a salt mine in eastern Germany. The plant uses econ’s unique batch-wise working mixing ...

  • A hot chance: exhaustive anaerobic digestion of “grey waste” under temperatures of pasteurization

    According to German laws municipal residual refuse MRR (biowaste, paper and glass are collected in separate bins) must be nearly mineralized before it will be deposited in a landfill, since this material can still contain 20 - 50 % biogenous organic matter leading to gaseous and liquid emissions. Especially the high-organic sieve fraction of MRR below 40 - 60 mm and with a thermal energy content ...

  • Removal of Particulate and Organic Matter from Municipal and Industrial Wastewaters Using Fine Mesh Rotating Belt Sieves

    The Salsnes Technology has been developed to work as a stand alone unit or an addition to primary wastewater treatment facilities. The process incorporates an continuous mesh screen that uses air as backwash therefore producing a high dry solids content waste. The technology has been widely accepted in Europe and work is being done in North and South America including installations and pilot ...

  • Pumps with extended service life for generating biogas from organic waste

    When regular commercial pumps are used to process organic waste, they typically wear out after only a short period of time. Liquids pumped under these conditions attack pumps from two different angles: first with highly abrasive additives and second with liquids that have highly fluctuating pH values and therefore a high level of chemical aggressiveness. These conditions are very tough on seals ...

  • Screen break detection with Paddy - Case Study

    Application In many industrial processes, the control of particle sizing by the use of mechanical screening is important to ensure correct material sizing. Damage to the screen will lead to large particles fl owing through, potentially leading to large amounts of incorrectly sized product. Associated costs of waste product, rework and product recall can be expensive for the ...

  • Separation

    Introduction: Ex situ separation can be performed by many processes. Gravity separation and sieving/physical separation are two well-developed processes that have long been primary methods for treating municipal wastewaters. Magnetic separation, on the other hand, is a much newer separation process that is still being tested. Gravity Separation Gravity ...

  • Wastewater treatment in a milk-processing company

    Description of the plant The accruing wastewater from the production of cheese and milk products is collected in a centralised pump sump and given to a first pre-treatment step. This step includes a separation of bigger parts by a sieve and a flocculation step with a dissolved air flotation for elimination of fats and cheese particles. After that, the pre-treatened water is buffered ...

  • Membrane fouling in the nanofiltration of landfill leachate and its impact on trace contaminant removal

    Nanofiltration (NF) is an attractive option for the treatment of landfill leachate. However, membrane fouling can be a major obstacle in the implementation of this technology. In this study, bench-scale filtration experiments were carried out to study the fouling behaviour during the NF of a synthetic landfill leachate. The results indicate that calcium in combination with organic matter could ...

  • Recycled glass as potential aggregate for concrete tiles: a statistical analysis of the physical and engineering properties

    This paper investigates the use of washed post–consumer Recycled Glass (RG) as replacement of 7.5% and 15%#37; silica aggregate in concretes used to manufacture roof tiles. Three grading of RG were studied, defined by the retained particles on the following US Tyler mesh sieves: 4–10 (4.76–1.68 mm), 10–20 (1.68–0.84 mm) and 20–50 (0.84–0.30 mm). Metakaolin (MK) was used to replace 7.5% and 15% ...

  • The Atritor Turbo Separator

    Due to the changes in restrictions and the increase in the cost of landfill, the Gypsum Industry is looking for an alternative to handle the estimated 300,000 tons of new build plasterboard waste generated every year. The traditional way of separating gypsum from its backing is to use hammer mills, in conjunction with sieves, which is costly and generates a lot of dust.Atritor offers reprocessing ...

  • Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory

    ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...
