  • Laboratory Filter Paper Suction Measurements

    Results of filter paper measurements for both matric and total suction values are reported for a sand, silt, and clay. Calibration curves for the matric and total suction are given for the filter paper used in this study, and comparisons with the results of several other researchers are made. For low suction values, the matric suction is more easily measured than the total suction using the ...

  • Suction-Moisture Content Calibration of Filter Papers from Different Boxes

    The filter paper method is probably the simplest of the methods available for estimating the suction of a clay soil. The method measures soil suction indirectly by simply measuring the moisture content of a filter paper having been brought to the same suction as the soil. Calibration of representative specimens of the filter paper over a range of known suctions defines the suction-moisture ...

  • VSEP replaces crossflow membrane systems, filtering industrial wastewater at pulp and paper mills

    Technological advances in membrane filtration systems have created an opportunity for pulp and paper mills to treat effluent streams in order to meet stricter environmental constraints. “Vibratory Shear Enhanced Processing” or VSEPÔ, developed by New Logic International makes it possible to filter effluent streams without the fouling problems exhibited by conventional membrane systems. The VSEP ...

  • Case study: Pulp & paper plant

    OverviewEuropaper produces tissues paper for Industrie Cartarie Tronchetti, which has its own branch (Foxy). Changes in the paper production were followed by an increase of the BOD load in the wastewater. Therefore the existing water treatment plant had to be upgraded. RequirementsAn increased BOD load in the wastewater, caused by a conversion of production, required an ...

  • Case study: Pulp & paper industry

    OverviewThe paper mill at Valdivia produces card board from chemical and mechanical pulp. With the installation of an additional paper machine, the wastewater flow increased from 4,000 m3/d to 8,500 m3/d and therefore an extension of the existing wastewater treatment plant was required. RequirementSo far, the existing effluent treatment plant consisted of a primary ...

  • What are filter aids?

    Filter Aids” is a group of inert materials that can be used in filtration pretreatment. There are two objectives related to the addition of filter aids. One is to form a layer of second medium which protects the basic medium of the system. This is commonly referred to as “precoat”. The second objective of filter aids is to improve the flow rate by decreasing cake compressibility ...

  • White Paper - Four Membrane Cleaning Profile

    Four Membrane Cleaning Profiles With Micro-90® Alkaline Cleaning Solution, Micro® Green Clean Biodegradable Cleaner And Micro® A07 Citric Acid Cleaner SUMMARY Fouling and cleaning profiles of four types of filter membranes were obtained using MICRO-90®, MICRO® GREEN CLEAN and/or MICRO® A07. Simulated fouling processes were performed by using either a ...

  • Controlling scale deposits in the pulp & paper industry

    The pulp and paper industry is one of the heaviest users of water within the North American industrial economy, requiring on average 54 cubic meters of water per metric ton of finished product.  As water is used in nearly every part of the manufacturing process, accumulation of scale is a phenomenon that can occur in all pulp and paper making processes. This occurs even with the purest water ...

  • White Paper: ANSI N13.1-2011 Stack Sampling Considerations

    Background Nuclear facilities are required to follow industry standards for sampling stack effluents. Exposure of the general public to released radionuclides must be monitored as specified in US governmental regulations. The United States Environmental Protection Agency (USEPA) and the United States Nuclear Regulatory Commission (USNRC) have the authority over the monitoring of these ...

  • Small Oil Filter Recycling Line

  • Comprehensive optimisation and practical design of LCL filter for shunt active power filter

    Shunt Active Power Filter (SAPF) can be applied to compensate for existing source-type current harmonics. However, high-precision compensation is difficult because harmonic current has a large variation and the current loop has a steady-state error. A design method for a new practical LCL filter based on SAPF is proposed in this paper. A harmonic model of the LCL filter is built based on SAPF ...

  • Oxygen Transfer in a Biological Aerated Filter

    The City of San Diego (City) operates the Point Loma Wastewater Treatment Plant (PLWTP) which can normally treat up to 240 million gallons per day (MGD) of chemically enhanced primary treated (CEPT) effluent for ocean disposal. The City wanted to understand the performance capabilities of Biological Aerated Filters (BAFs) in treating CEPT effluent to secondary standards. To this end, the City ...
