  • Canarina DESCAR software · wastewaters · complex organic chemicals industry · commands 6

    In the center of the program window, we will draw and we will calculate the different polluting processes. We can draw using two different planes: parallel to the surface of the water (XY) and perpendicular to the surface of the water (XZ). There is a grid in the XY-plane. The coordinate origin is on the left bottom corner (X=0, Y=0) in XY-planes (parallel to the surface of the water). In ...

  • Can a moving bed bioreactor reduce toxicity of complex industrial wastewater?

    MeadWestvaco Corporation in DeRidder, Louisiana refines crude tall oil (a byproduct of black liquor) to produce a variety of specialty chemicals products. The facility generates approximately 0.46 million gallons per day (mgd) of wastewater that require treatment for total recoverable phenols (TRP), chemical oxygen demand (COD), biochemical oxygen demand (BOD), and whole effluent toxicity (WET). ...

  • Reduced Emissions for Landfill Gas Installations

    The use of landfill gas as a source of renewable energy is increasing. For environmental and safety reasons, the owners of the waste storage sites have to strictly monitor and control the construction, operations, and emissions generated. Sulzer offers solutions to control these emissions within the limits given by the government. Landfill gas is similar to natural gas, but it is created by ...

  • Nitrogen removal in tertiary wastewater treatment plant of a chemical complex

    A Biochemical Contact Oxidation Film (BCOF) technique was piloted for the treatment of a secondary effluent of the Jilin Chemical Industry Corporation (JCIC). The original pulse contact flocculation clarifier used for the tertiary treatment was not performing to the discharge standards. Results show that NH3-N concentration was decreased from 30 mg/L to 15 mg/L, COD concentration was decreased ...

  • An ecological engineering system model applied to the case of an integrated agro-industrial complex

    Intensive stock breeding namely swine, beef and dairy cattle and related activities are characterised by an enormous pollution potential. Without suitable treatment, this kind of waste with high levels of organic matter, nutrients, heavy metals and pathogenic microorganisms originates air, water, soil and food chain contamination. The removal or the reduction of the pollutant matter contained in ...

  • New Approaches for Simulating Complex Flows

    When it comes to simulating the flow of material mixtures, classical CFD (computational fluid dynamics) methods reach their limits. For several years now, Sulzer has been pursuing a fundamentally new approach—the Lattice-Boltzmann method—working closely with an external research partner (FlowKit SA). Sulzer uses this method to simulate specific products, and this method makes it ...

  • Water and wastewater treatment for Solar industry

    Solar cells arc manufactured in a complex process thai requires enormous know-how. The objective is to produce panels with a high level of efficiency at low cost. To achieve this, different production processes are used. A fundamental distinction is made between solar cells on the basis of silicon wafers and thin-film cells, in which a special process is used to apply the photovoltaic layer onto ...

  • Test organisms behaviour on municipal and industrial wastewater quality assessment

    Industrial wastewaters quality became a target for the environmental toxicity assessment nowadays. When there are issues with complex effluents for which many chemicals cannot be quantified and/or interactive effects are likely to be significant, the use of bioassays with different test species becomes a more reliable way in the assessment of toxicity. Ecotoxicity evaluation of the several ...

  • Adsorption characteristics of bio-adsorbent on chromium(III) in industrial wastewater

    The removal of chromium(III) (Cr(III)) from industrial wastewater by various low-cost methods has been widely investigated. In this paper, a type of bio-adsorbent was prepared using rice straw modified by fermentation and simple chemical treatment. The aim is to detect the adsorption mechanism and characteristics on Cr(III) ions. The analysis shows that the bio-adsorbent possesses four ...

  • Membrane Bioreactors for Industrial Wastewater Treatment: Applicability and Selection of Optimal System Configuration

    ABSTRACTThe membrane biological reactor (MBR) configuration has proven to be optimal for treatment of many industrial wastewaters when treatment efficiency is an important consideration. Since installation of the first large, U.S., full scale MBR system for industrial wastewater treatment at the General Motors plant in Mansfield, Ohio in the early 1990s, use of membranes for biomasseffluent ...

  • Organic matter and heavy metal removals from complexed metal plating effluent by the combined electrocoagulation/Fenton process

    In the present study, the treatment of metal plating wastewater containing complexed metals originating from the nickel and zinc plating process by electrocoagulation (EC) using stainless steel electrodes was explored. In order to improve the organic matter removal efficiency, the effect of H2O2 addition to the electrocoagulation (the combined EC/Fenton process) application was investigated. For ...

  • Optimizing Wastewater Treatment

    ' Growing volumes of both industrial and municipal wastewater are being discharged to surface waters but the treatment provided frequently is inadequate to protect the desired uses of the receiving waters. With limited resources in terms of both institutional capacity and finance, governments face difficult choices in optimizing their investments in municipal systems and establishing practical ...

  • The biological basis of wastewater treatment

    Introduction This booklet was written to fulfil the need for a simple explanation of the biological processes that underpin wastewater treatment. It attempts to show how the bacteria involved deal with the organic carbon in the sewage. Remarkably, there are just 3 major processes involved, and these mirror exactly the 3 major processes at work in the plant viz: biodegradation, oxygen ...

  • The natural way to clean wastewater

    John Todd founded Ocean Arks International in the 1980s, where he started to experiment with processes that mimic natural ways to purify wastewater. He built a greenhouse and ran sewage through a series of tanks, with plants suspended in the flowing waters, and constructed marshes made of sand and gravel. No chemicals were added, but plenty of aquatic creatures from snails to small fish were ...

  • Wastewater Treatment in Turbo Mode

    Sulzer turbocompressors type ABS HST are successful in wastewater treatment. Today, 2000 units are installed around the world—for example, in municipal plants like in the city of Sögel, Germany. Here, the turbocompressors not only reduced the operating costs but also helped the plant to cope with load fluctuations. The secret behind this success is an advanced design with proven ...

  • Integrated Wastewater Management

    ' Appropriate wastewater management, within an overall water resources management program, is essential to responsible use of the environment and to affordable provision of services. Such management programs are best developed at a river basin or sub-catchment level. An approach is outlined for developing a wastewater strategy and an implementation plan for a river basin.' Integrated ...
