Environmental FacilitiesVent Gas Incinerator SystemBio-Treatment SystemSince local exhaust ventilation contains various components with often lowconcentration, the combustion method is advantageous.FeaturesEffluentFacility Design Concept Sludge reduction Energy saving Energy generationAnaerobic treatment with small methane fermentater granulesa)Thermal Oxidizer■Applies to gas containing much dust or waste gas with high heatingvalue.Featuresb)Catalytic Combustion System■Consumes the least amount of fuel among the three methods.■No flame is used, so reaction temperature is mild and the risk is small.Accurate distribution of granules by multi-stagereaction zones, and control over small-sizegranules.■Significantly higher performance than theproducts made by other companies■Realizing high reduction rate in the high load conditionThermal OxidizerLocal exhaustventilationFuel / Waste oilCombustion airProcess Flow ofCatalytic Combustion SystemCatalyzerExhaust stackWaste liquid /WastewaterProcess Flow ofThermal OxidizerFuel / Waste oilExhaust stackAnaerobictreatment■Application: Organic compound concentration■Target: 0.5 to 3 wt%Organic volumetric loading rate: 50 to 80kg/m 3・DOrganic removal rate: 95% (verified with artificial glucose water)Combustion airExhaust gasCatalytic Wet Air Oxidation SystemDetoxifying COD components in Effluent water by catalyst with high-efficiency liquidphase oxidation reaction.Conventional granules(produced by other company)φ3mm toφ5mmTSK Granulesby High-Efficiency UASBφ1mmWAO is a high-efficiency liquid-phase oxidation reaction process developed under technical licensee from Nippon Shokubai Co., Ltd.High running costs were a drawback for conventional combustion treatment. With WAO, a solid catalyst performs efficientliquid-phase oxidation and decomposition of COD components in effluent water, at high temperature and high pressure, WAO not onlyexhibits high performance for persistent cases that are difficult with biological treatment, but is effective for treating effluent water withmuch inorganic COD components as well.Features of Aero SlalomAerobic treatment using f ixed biof ilmWAO ProcessWAO process decomposes organic compounds into air, oxidant, CO 2 andwater in the catalytic reaction chamber.Nitrogen compounds are decomposed into N 2, generating virtually no NOx.Sulfuric compounds are detoxified after that sulfur components are changedinto Na 2SO 4 through decomposition with a catalyst and addition of NaOHsolution.Operative ConditionsLow/pressure method~0.9MPaG (9kg f / cm )~165℃(Pressure Vessels of Grades 1 and 2)OrganiccompoundsNitrogencompoundsSulfuriccompoundsCatalystAirCO 2H 2ON 2SO 2- 4Aerobictreatment■Rotating aeration tube installed at the bottom of the reactor continuously supplies air to the fillerinside the reactor■Periodic air shearing effect on the whole surface of the filler prevents clogging the fillerMain Uses■Reduction of organic materialsas pretreatment of activatedsludge unit in the next stage■Direct discharge to sewagetreatment plant withoutsettling tanks at the next stageAero SlalomEffluentDirect sewage dischargeActivated sludgeat the next stageTSK Aeration PanelRorHigh/pressure method~7.3MPaG (73kg f / cm )~265℃(High-Pressure Gas Safety Law.
