Definitions

  • the present invention relates to an antibacterial membrane and a production method thereof which is used especially in water treatment, and eliminates the fouling problem occurring as a result of accumulation of microorganisms.
  • the intermediate surface which controls passing from one phase to another phase depending on several characteristics of the different materials between two phases is called membrane.
  • the membrane processes are classified in 4 different processes being microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO) as removal efficiency and pore diameter.
  • MF microfiltration
  • UF ultrafiltration
  • NF nanofiltration
  • RO reverse osmosis
  • Membrane filtration is one of the most efficient processes which enable to purify waste water, drinking water and industrial waste water in an advanced level.
  • a decrease is seen in time in the filtrate flux and removal efficiency of the membranes used in membrane filtration.
  • the main reason for that is membrane fouling.
  • Membranes are designed for the removal of particular material or microorganisms, biofouling, which is an unwanted situation, occurs on the membranes as a result of the materials accumulating on the surface of membrane or membrane pores.
  • inorganic nanoparticles have been started to be used in order to enhance the performance of membranes. Especially the antibacterial property exhibited by the nano dimensional metallic materials is effective for solving membrane fouling problems.
  • inorganic nanoparticles are added to the polymer as mixture and these kinds of materials are called as nanocomposite material.
  • nanoparticles such as titanium dioxide (Ti0 2 ), catalytic metal nanoparticles, zeolite, and aluminum are used.
  • Rahimpour et al. obtained antibacterial membrane by adding Ti0 2 nanoparticles on the surface of membranes prepared with PVDF/sulfonated polyethersulfone in their study.
  • Antibacterial property of the membrane was obtained with H 2 0 2 and HO radicals formed on the surface after contacting UV.
  • PVDF polyvinyldenfluoride
  • EP2509614 discloses obtaining antibacterial effect by adding antimicrobial peptides on the surface of thin film composite membranes used in reverse osmosis systems.
  • United States Patent documents no US20020051819, US 20030050247, US20030194445, US20050065072 and US20060166883 disclose industrial studies carried out with antimicrobial peptides.
  • Fouling is the main problem in systems wherein membrane technologies are used. Fouling can be conventionally controlled with methods such as back washing with filtrate water, flushing the membrane surface and chemical washing. However, none of these methods is an exact solution. In addition to the backwashing, membranes are chemically washed.
  • Nanotechnological methods used for decreasing biofouling also have disadvantages such as their high cost and leaching of metallic nanoparticles from membrane matrix.
  • the antibacterial membranes obtained with photocatalytic nanoparticles such as Ti0 2 requires continuous UV contact. This complicates system operation and limits module configurations.
  • the objective of the present invention is to provide an antibacterial membrane and production method wherein bismuth chelate is used.
  • a further objective of the present invention is to provide an antibacterial membrane which has low both operation and investment cost, easily scalable to industrial scale.
  • Figure 1 is the flow chart of the inventive antibacterial membrane production method.
  • Figure 2 is the graphic wherein the inventive antibacterial membranes and the membranes used in the technique are compared, and which shows the amounts of outlet water obtained from both membrane filtration experiments.
  • the inventive production method (10) comprises the steps of;
  • first bismuth chelate is synthesized (11).
  • first bismuth nitrate pentahydrate is dissolved in propylene glycol (1 1) and the prepared solution is mixed with 2,3-dimercapto-l-propanol and is stirred until a homogenous composition is obtained (112).
  • IN NaOH is added to the solution for pH adjustment.
  • Bismuth chelate synthesis (11) is preferably carried out at room temperature at pH range of 2-12, and preferably pH 3 to 5.
  • the molar ratio of bismuth nitrate pentahydrate:2,3-dimercapto-l-propanol in the prepared bismuth chelate can vary between 3: 1 and 1 : 1. In the preferred embodiment of the invention this ratio is 1 :1.
  • the inventive antibacterial membrane is produced by using this chelate (12).
  • prepared bismuth chelate in previous step is added on the dimethylacetamide solvent (121).
  • bismuth chelate is added in ratio of 1 5-30 micromolar.
  • polymer is added to this composition (122).
  • Polyvinylpyrrolidone (PVP) and polyethersulfone (PES) are used as polymer.
  • PVP polyvinylpyrrolidone
  • PES polyethersulfone
  • PSf polysulfone
  • PVDF polyvinylidene fluoride
  • PAN polyacrylonitrile
  • total PVP ratio was 2-15%
  • the PES ratio was 5-25% in the solution.
  • this ratio was chosen as 8% for PVP and 16% for PES .
  • Preferably water induced phase inversion technique is applied for forming membranes (125).
  • the liquid polymer solution is immersed into water and the solvent in the solution is vaporized, the exchange between nonsolvent (water) and solvent is occurred which leads to membrane pore formation.
  • First liquid polymer solution is poured on the supporting layers (unwoven fabric) in thickness of 90 ⁇ . Then the support layer is moved at various speeds (10-150mm/second). Doctor blade is passed through the liquid polymer solution on the supporting layer. The membrane thickness on the support layer is fixed such that it will be in range of 50-500 ⁇ .
  • the polymer solution passing from the doctor blade enters into the water bath after a short waiting period. Therefore the exchange between non solvent and solvent is occurred and polymer precipitates, thus the membrane structure is formed.
  • membrane thickness is controlled in different points of the membrane, they are taken to plastic containers comprising water in order to be stored. These containers are kept in a cold room approximately at 0°C.
  • condition in synthesis of the inventive antibacterial membranes three different parameters are taken as basis, namely temperature, pH and bismuth nitrate pentahydrate:2,3-dimercapto-l-propanol molar ratio.
  • Room temperature and 25 and 45°C representing high temperature conditions are selected as temperature; pH 4, 7 and 10 values are respectively selected for representing acidic, neutral and basic conditions for the optimization of pH.
  • 3: 1, 2:1 and 1 : 1 ratios are selected in order to optimize bismuth nitrate pentahydrate:2,3-dimercapto-l-propanol molar ratio.
  • the inventive antibacterial membrane is easily producible at industrial scale and it is also easy and cheap to use since it does not require extra process.
