  • Biosolids ban struck down

    In 1994, Los Angeles County Sanitation Districts (LACSD) bought a 4,700-acre farm (called Green Acres Farm) in southwest Kern County for the purpose of land applying biosolids from its 11 wastewater treatment plants. LACSD land applied 800 wet tons/day at this site for several years. In 2006, Kern County voters passed Measure E on the ballot with 83 percent approval. This measure banned ...

  • 10 Reasons why you should continuously monitor low temperature and liquid chemical sterilants for worker safety

    1. Sterilant chemicals are highly toxic Low temperature and liquid chemical sterilants are designed to kill all microorganisms including resistant spores and if they were not toxic, they would not be effective in sufficiently high concentration to destroy all microbial life including the chemically resistant sporicidal forms of certain ...

  • Several waste gas streams: Highly contaminated oxygen-free waste gas, and medium waste gas stream - Case Study

    Example: Chemical industry Similar tasks: Petrochemical and pharmaceutical industries A producer of synthetic rubber creates a medium waste gas as well as a highly contaminated oxygen-free waste gas which contains primarily low hydrocarbons. The main waste gas stream is purified in a regenerative thermal oxidiser (RTO), while the oxygen-free waste gas passes through ...

  • Optimum waste interception in Liquefied Natural Gas processes

    This work addresses optimum waste interception and wastewater minimisation in liquefied natural gas (LNG) processes. The problem involves solvent regeneration and purification using distillation. The scope of this paper focuses on determining optimum impurities (waste) composition (accumulation) in the solvent loop while considering energy integration scenarios including pressure of the ...

  • Comparison of Gas and Water Pycnometry of Coal Mine Wastes

    Coal mine washery wastes comprise two major components whose specific gravities differ markedly. Consequently, their specific gravity is much more variable than that of natural soils and is determined relatively frequently. The specific gravity of coal mine wastes is determined more rapidly and efficiently by gas pycnometry than by water pycnometry. However, the two methods give significantly ...

  • Liquid waste off-gas treatment - Case Study

    Application Biffa Waste Services operate a major waste disposal site at Kilsyth in Scotland where they handle many types of industrial liquid effluent. This can give rise to a range of emissions from both the tank farm and the road tanker deliveries. In addition, significant NO2 and nitric acid fume releases can arise from process upset conditions. ERG provided an emergency NO2 ...

  • Landfill waste gas abatement - Case study

    For over 43 years Catalytic Products International has designed and manufactured specialized oxidation systems for use in controlling process-related VOC emissions. The QUADRANT-NRV Series Thermal Oxidation System is designed for use with the low-volume/high-BTU waste gas stream emitted from many landfill gas purification processes. As we utilize our Venturi Burner Package to process the waste ...

  • Zero Waste - Zero Waste - Zero Waste

    The Planning Group of the Zero waste International Alliance defines zero waste as: “Zero waste is a goal that is ethical, economical, efficient and visionary, to guide people in changing their lifestyles and practices to emulate sustainable natural cycles, where all discarded materials are designed to become resources for other use.” I recently posted this question on ...

  • Waste not, want not

    Consultant Andy Ive considers solutions which not only comply but also enhance the environmental profile of today’s industrial companies. Until recently the prevailing perception in many industries, particularly those operating in emerging market areas has been that waste is an unwelcome inconvenience. The primary infrastructure of most companies was fundamentally not designed to deal with waste ...

  • Optimizing The Operation And Material Selection For Fluorinated Waste Gas Incineration

    A thermal oxidizer system is used by Honeywell Specialty Chemicals to reduce organic and acid gas emissions from their fluoro-products plant. The thermal oxidizer system consists of a multi-gas fired vortex burner mounted on a vertical residence chamber. ...

  • Flameless Thermal Oxidation For Chlorinated Waste Vent Gas Destruction

    Faced with a need to reduce nitrogen oxide (NOx) emission levels, a major gulf-coast chemical plant proactively evaluated several strategies and technologies that could be implemented to maintain compliance, selecting Selas Fluid's Thermatrix flameless thermal oxidation technology. ...

  • Biofiltration systems for the treatment of waste gas from industrial plants

    Bord na Móna Environmental Ltd have considerable experience in the field of biological air filtration (600 installations). Initially, the majority of installations were on Municipal and Industrial Wastewater applications. This was quickly followed by Municipal Solid Waste, an application Bord na Móna jointly developed with its Italian partners Air Clean srl. Since 2000, Bord na Móna have ...

  • Waste Gas Cleaning for Road Tunnels and Underground Car Parks

    The objective of the study was to find a microbiological cleaning technique for road tunnel waste air, with emphasis on CO, NO and NO2. The chemolithotrophic CO oxidizing mixed population with an integral part of nitrifying bacteria carry out an essential step in metabolic process of NOx consumption. The immobilized microorganisms were subsequently exposing them to a constant stream of artificial ...


  • Very large waste gas volumes with low contaminant concentration - Case Study

    Example: Electronics industry Similar tasks: Paint shops, spectacle coating, coating on the inside of cans The electronic industry produces semiconductors that generate very large waste gas streams that are only slightly contaminated. These waste gas streams are purified in rotary adsorbers. The continuous regeneration of the adsorbers generates highly contaminated ...

  • Process for the Separation of Gas Products from Waste Tire Pyrolysis

    In recent years, pyrolysis has proven to be an effective thermochemical process for the recycling of waste tires. After pyrolysis, three fractions are obtained:  carbonaceous solids, liquid hydrocarbons, and the so-called noncondensable gases. In this paper, the starting point is the pyrolysis reactor outlet that provides a gas stream with a temperature of 600 ...
