EcoSense International, Inc. VaultOx

  1. 1. Proprietary and Confidential ©2009 EcoSense• EcoSense International Inc. formed in 2000• EcoVaultTM , The Next Generation Baffle Boxes• EcoSenseTM, Inlet Insert Filtration and Debris Collection• Oxy-ProTM, Environmental Redox Chemistry (Nitrate Reduction)• Smart GrowTM, Environmentally Sound Fertilization and Weed Control• Vault-OxTM, Static Stormwater Remediation Chemistry
  2. 2. Vault-Ox™ Net 20 lbs. Contains (4) 5 lb. packetsKeep material dry. Store in a cool dry place.Do not store or expose to heat sources. Formore information see Material Safety DataSheet.
  3. 3. Interevent Water Quality in Manufactured BMP’s• Strynchuk, Royal and England, 1999 Reported “the majority of organic-based pollutants, which leach from grass clippings and leaves into water will be released within 1 to 22 days…BOD peaked at 9 days…most of the phosphorus was released in the first day…”• Marino and Gannon, 1991 Tested storm drain sediments during dry weather periods and found “Extended bacterial survival in sediments to survival in water…FC and FS in sediments remained stable for up to 6 days (the maximum inter-storm dry period).”• GPI Southeast, in the Final Report – Baffle Box Effectiveness Monitoring Project, 2010 reports “net exports of fecal coliforms and anaerobic conditions…” and suggest “probable causes for FC growth in baffle boxes are the interevent anaerobic conditions…” and point out “…use of any water storing box can lead to increased FC counts to water bodies”.
  4. 4. Introducing Static StormwaterRemediation Chemistry SSRC Vault-Ox™  Improves Dissolved Oxygen  Sequester Phosphates  Elevates pH  Absorbs Nitrogen  Promotes Oxidation of Organics  Enhances Aerobic Activity  Lowers COD/BOD  Affordable and lasting
  5. 5.  Patented dry chemical containingVault-Ox™ calcium and oxygen  Practically insoluble but slowly degrades to release oxygen  Sequesters phosphate: precipitates as CaPO4 or FePO4  Improves aerobic bioremediation  Raises pH to alkaline state:  Keeping metals out of solution  Stormwater quality structures  Underground water storage  Ponds  Ground water remediation
  6. 6. Properties of Vault-Ox™ Granules  Appearance Yellowish white granules  Composition CaO2 and additives  Calcium peroxide (%) 70% min  Available oxygen (%) 15.5% min  Metal impurities Meets Food Chemicals Codes  Particle size (90%) ~ 500-2000µ 7.5  pH (0.05% suspension)
  7. 7. Chemistry of Vault-OxTM in Water At natural pH – very slow decomposition generating oxygen and lime 2 CaO2 + 2 H2O 2 Ca(OH)2 + O2 Rate of oxygen generation depends upon  Product characteristics - particle size, formulation, etc.  Environmental conditions - water quality, pH, agitation, concentration, etc.
  8. 8. Vault-OxTM A source of Alkalinity Increases the formation of calcite and apatite  This increases the P-binding capacity of calcium Reduces free H2S concentrations Formulation buffers and regulates pH Counters acid rain Prevents acidification of water when sulfides are oxidized Maintains heavy metals in an immobilized oxidized state
  9. 9. Chemistry of Vault-Ox™ in Acid In buffered systems at lower pH, CaO2 dissolves faster and produces progressively increasing amounts of H2O2 CaO2 + 2H+ Ca2+ (aq) + 2H2O2 Ca(OH)2 + 2H+ Ca2+ (aq) + 2H2O
