Presentation Transcript

  1. Rajni Patel • Gopani Product Systems • 13th Sep. 2013

  2. Porex Corporation • Working in partnership with world leaders in global markets • Innovating with a Materials Science and Engineering focus • Providing structural porous solutions to real world problems

  3. Global Facilities Support an Efficient Supply Chain And Provide Manufacturing Redundancy

  4. Porex Filtration Division Brings unique product solutions to high-solids filtration and separation applications, utilizing proprietary materials and membrane technology.

  5. Tubular Micro Filtration (TMF) What is TMF • Microfiltration (MF) is a low pressure (0.7 – 7 bar, 10-100 psig) separation process for separation of solids from aqueous solutions by means of a membrane. • This “crossflow” process is carried out by having a process solution flow along a membrane surface under pressure. • Retained particulate matter leaves with the flowing process stream and does not accumulate on the membrane surface

  6. Why the Porex TMF Membrane is Better • Unique abrasion resistant topography • PVDF membrane with PE or PVDF sintered substrate • Membrane is in the pores of the substrate • Anchored into substrate by full depth entanglement • Also chemically bonded in the PVDF/PVDF option

  7. Tubular Membrane Filter Module (TMF) • Membrane with nominal pore size of 0.05, 0.1, 0.5 • PVDF membrane material • HDPE or PVDF substrate material • Tubular configuration with 1” or 1/2” diameter • Housing materials of PVC, CPVC, SS, all PVDF, other options on request. • Up to 43°C Temperature PE, up to 80°C Temperature PVDF tubes (continuous operating temperature)

  8. Microfiltration System/Processes • The Porex TMF Membrane is Unique and Proprietary • An efficient filter for high solid and liquid separation • Chemical and abrasion resistant membrane • Low SDI (typically less than 0.5 NTU) allows for further processing

  9. Performance Attributes • High Flux • Typical operation flux rate 300-500lmh • High solid concentration solids level • requirements up to 5% (by weight) • Excellent Chemical Resistance • pH 1-14 • Backwashable • Unique membrane anchor points allowed backwash • Minimal Construction Materials • Simple system design minimized the construction cost.

  17. Backwash • Backpluse: • Often PLC controlled • Typically engaged every 5 – 30 minutes (20 is standard). • Used to prevent excessive solids accumulation on membrane surface • Filtrate is forced back through membranes using air pressure

  18. Tubular Micro Filtration (TMF) Technology Typical Membrane Cleaning Chemicals • Acid: 5-10% H2SO4 or 5-10% HCl solution (removal of metals) • Alkaline: 3-5% NaOH solution (removal of silica, some organics) • Oxidizers: Acidic solution (mixture of 5-10% H2SO4 / 3-5% H2O2) Alkaline solution (mixture of 5-15% NaOCl / 1-3% NaOH) (removal of organics)

  19. Tubular Micro Filtration (TMF) Chemicals Used in MF treatment Typical pretreatment chemicals • Precipitants • Calcium chloride – fluoride or phosphate removal, • Magnesium chloride – silica removal • Sodium Carbonate – calcium removal • pH adjustment • Sulfuric acid (H2SO4), hydrochloric acid (HCl), sodium hydroxide (NaOH), lime (Ca(OH)2) • Oxidizing Agents • Hydrogen peroxide (H2O2), bleach (NaOCl) • Reducing Agents • Sodium metabisulfite (Na2S2O5), sodium bisulfite (NaHSO3)
