All design projects need to be tested in the early stage of the project, and pilot-scale experiments are carried out when necessary to ensure the stable operation of the project design.<3>The company independently develops and manufactures steam compressors to ensure the quality of MVR core components<4>PROCRSS INTRODUCTIONR & D background: As per different production process, the kinds and chemical properties of organic matter in high salinity organic wastewater vary greatly, but most of the salts are Cl-, SO42-, Na+, Ca2+. If directly discharged,It would pollute the environment ; and the biochemical treatment process is more difficult to deal with. Although these ions are essential nutrients for microbial growth, they play an important role in promoting enzymatic reaction, maintaining membrane balance and regulating osmotic pressure in the process of microbial growth, but if the concentration of these ions is too high, they will inhibit and poison microorganisms. High salt concentration, high osmotic pressure and microbial cell dehydration in high-salt wastewater cause cell protoplasm separation; salting-out reduces dehydrogenase activity; high chloride ion is toxic to bacteria; high salt concentration and increased density of wastewater make activated sludge easy to float and drain, thus seriously affecting the purification effect of biological treatment system.High Salt Water Sources:High Salt Wastewater from Chemical Production ProcessWastewater treatment from chemical industryHigh Salt Wastewater in Freshwater Recycling and Utilization ProcessHigh salt hazardness:Soil hardening Pollution of groundwater endangers people's health Pollution of water sources and endangerment of biodiversity Corrosion equipment Influencing Normal Biochemical Sewage Treatment High saltwater treatment:Treatment technology:Evaporation treatment Biochemical treatment Incineration treatment Electrolysis treatment Ion exchange treatment Membrane concentration treatmemt Technology compare:ItemEvaporatorElectrolyzeIon ExchangeIncineratorMembrance ConcentrationOperational difficultyLowbiggerNeed regeneration, operation is difficult, automation is difficult.bigoperation easy,stable function,high automationFloor spacesmallersmallerbig bigsmallInvestmentlowhighpretreatment is easy,but high requriement on valve higherhigh requirement on pre-treatment,pre-investment is highEnergy costslowhighhigh costs for high salt percentagehighlowmaintenancelowerhighHigh acid/alkali losshigh high maintenance on membraneApplicationwidecan not process organiccan not process organic wider can not deal with high salt waterEvaporator Technology:It means that the pressure * Volume / temperature of a gas of a certain mass is constant, which means that when the volume of the gas decreases and the pressure increases, the temperature of the gas will also rise.; According to this principle, when the thin secondary steam is compressed by volume, its temperature will rise accordingly, so that the low-temperature and low-pressure steam can be transformed into high-temperature and high-pressure steam, and then it can be used as a heat source to reheat the raw liquid which needs to be evaporated again, so as to achieve the purpose of recycling and utilizing steam.Because the compression of this volume is achieved by mechanical compressor, it is called MVR.MVR evaporation chartTechnology Comapare:Conventional evaporation requires a lot of cooling water to cool the heat of secondary steam (make it condense), and then the heat of cooling water is released into the atmosphere through cooling tower, which not only consumes fresh steam, but also consumes a lot of circulating water and power (pump) operation, resulting in triple waste.MVR technology can compress and reuse secondary steam which needs condensation to replace fresh steam. It not only avoids the use of fresh steam, but also completely abandons the cooling tower, greatly reduces operating costs, and truly achieves environmental protection, energy saving, water saving and cost saving.90%Compared with single effect, MVR can save 90% of the cost per tonTechnology Compare:NoItemMVRThree Effect1operation difficulity high automation,less machines,easy operationhigh automation,more machines,operation not easy,more fault point,one effect failure whole system shutdown for maintenance,not economical2Floor Spacesmall big3Investmenthighlower by 30% compare with MVR4Energy costlow,save by 74% per ton compared with three effectbig quantity(three effect second steam cooling)5Cooling water consumptionsmall (machine mechanic seal cooling)big quantity(three effect second steam cooling)6Applicationlow boiling point arise,around 5-10ºCcould evaporate higher boiling point material7Effect on product qualityShort stay time, low temperature differential evaporation, minimal impact on product qualityThe stay time is longer and the temperature is higher, which has little effect on the product quality.MVR Flow ChartProcess equipment:Advantages :Operation Parameters:Project Reference:Project nameProcess capacityEnduser addressmixed wastewater of sodium nitrate,sodium chloride and sodium sulfate from metal smelting5ton per hourSICHUAN PROVINCEzero discharage of mine smelting wastewater6.5ton/hourYUNAN CHUXIonGzero discharge of reclaimed water3ton/hourInner MongoliaPaper material waste water5ton/hourHenan Jiaozuocrystallization of ammonium sulfate and sodium sulfate15ton per hourBinzhoudesalination of sodium sulfate wastewater4TON PER HOURSHANDONG JINANcrystallization of sodium sulfate wastewater3ton per hourSHANDONG JINAN DIAOTOWNconcentration of sodium hydroxide6.5ton/hourSHANDONG JINAN DIAOTOWNdesalination of sodium chloride wastewater3t/hSHOUGUANGzero discharge of amonium nitrate wastewater1.8TON PER HOURSHANGHAIhazardous waste leachate3TON PER HOURXINTIANDI INDUSTRIAL AREAShazardous waste leachate2ton/hourXINTIANDI INDUSTRIAL AREAShazardous waste leachate4Ton/hourXINTIANDI INDUSTRIAL AREASreclaimed water recycle4000ton/dayTIANJINcutting fluid concentration200L/hTIANJINseparation of mirabilite and sodium carbonate by evaporation with sodium sulfate and sodium carbonate27t/hSHANXIcrystallization of sodium sulfate from xylose wastewater2TON/HOURZHANGQIUsodium sulfate containing wastewater for preparation of sodium bicarbonate powder1.5TON/HOURHUANGHUA CITYbromide industry wastewater5TON/HOURSHOUGUANGsodium sulfate-containing wastewater for preparation of sodium bicarbonage powder2TON/HOURWEIFANGsodium sulfate-containing wastewater for preparation of sodium bicarbonage powder1.8TON/HOURTIANJINcrystallization of wastewater containing sodium chloride (dye chemicals)10TON/HOURInner Mongoliasodium sulfate-containing wastewater for preparation of sodium bicarbonage powder2TON/HOURTIANJINpretreatment and crystallization of sodium sulfate and sodium chloride wastewater3t/h3TON/HOURJIANGSU YANCHENGconcentration and crystallization of sodium chloride wastewater1t/h1TON /HOURSHANDONG DonGYINGconcentration of fluorescent agent wastewater0.5TON/HOURSHANDONG JININGcrystallization of sodium sulfate wastewater1.3TON/HOURHEBEI SHIJIAZHUANGammonium sulfate crystallization1.5TON/HOURTonGXIANGcrystallization of sodium chloride wastewatecrystallization of ammonium sulfate waste water1t/hSHANDONG ZIBOcrystallization of sodium chloride wastewater1t/hTIANJIAN JINGHAIcrystallization of sodium chloride wastewater4.2t/hSHANDONG BEIYUEconcentration of pyromellitic acid1.5ton/hourHEBEI PROVINCEcrystallization of cellulose sodium chloride1.3ton/hourHEBEI PROVINCEFine chemical waste water5ton/hNANTonGwastewater recovery from tailgas0.5ton/hourZHEJIANG HAIMENChemical waste water1ton /hourHBEEI CANGZHOU<5>In order to recommend client the most suitable solutions,Pls check below list and feedback to us:Component of raw material Capacity(t/hour)Input concentration(%)Input temperature(ºC)Toxic OR NOTCODTDSFoaming or notColorMain OrganicImpurity or notCrystalliseor notOdor or notPHfluorineammoniavolatilityCa,Mgchlorinesuspended substancecorrosivenessRaw material requirementviscosityFloatoilflammable and combustibleEvaporationRequirementconcentrationrequirementcrystallizationrequirementCrystal color:________ crystal size:________ crystal purity:________ Other requirement:________Energy consumption requirementCondensate waterrequirementRecycle or Disharge(Discharage standard)Waiting for your inquiry!
