When producing Sodium sodium metabisulfite(SMBS), during the manufacture process there is SO2 gas can come from sulphur, pyrite, hydrogen sulfide incineration or other tail gas problem and waste treatment control .
1)waste water
No waste water generated in our factory.
2)Waste gas
1. Source and composition of waste gas
waste gas is mainly from synthesis tail gas, and drying tail gas, negative pressure induced air. SO2 content in each part
10. Packing : External packing is PP woven bag, Internal packing is PE bag,25 kgs, 50 kgs, 1000 kgs, and 1250 kgs bag packing.
11. Storage & defence: Stored in cool and dry place, avoid moisture and heat. No breakage, No mixed with oxidant and toxic matter. The storage period is 6 month since the production date. It should be transported by clean car, with covering matter, avoid rain.
