MITSUBISHI CHEMICAL AQUA SOLUTION is one of the leading companies in the field of production of hollow-fiber membranes. The company was established in 1952 in Tokyo, Japan, and has been approved by the Japanese Ministry of Health for water quality analysis. With ISO9001 and ISO14001 certifications, the company has completed more than 5,000 successful MBR (biological reactor) projects worldwide. Also, these membranes are used in chemical, electrical, pharmaceutical, paper, and food industries and hospitals and hotels.

Supplementary wastewater treatment

The biggest advantage of ultrafiltration is that filtered water has a uniform water quality independent of the level of primary water contamination. Second, ultrafiltration is not dependent on external factors, which means that it provides water of constant quality.

  The main results of using ultrafiltration (UF) include:

  • Reduction of TSS or the suspended solids.
  • Reduce turbidity and color of water or effluent.
  • Eliminate microbial agents and viruses.

As a result, the use of immersed ultrafiltration has the following advantages:

  • High-quality purified water for reuse or discharge and its output is suitable for RO feed water.
  • Simple design and compact size can be used to upgrade and reduce the size of the treatment plant.
  • Has a lower risk of changes in the quality of feeding water and sludge entry. As a result, its operating costs are reduced.

The ultrafiltration process is the final stage of wastewater treatment to remove suspended particles and bacteria and reduce organic matter.

In addition, these types of membranes are also used in water pre-treatment in reverse osmosis systems. One of the major adverse events that occur in reverse osmosis systems is membrane clogging. Fouling refers to the adhesion of materials such as mud, clay, sand, suspended solids, biological sludge, algae, silica, iron clots, and the like to the surface of the membrane, or worse, penetration into cavities. The phenomenon of “clogging” usually occurs in the initial membranes in the first stage of the reverse osmosis system and gradually spreads to the subsequent membranes.

MITSUBISHI ultrafilter hollow-fiber membranes are produced under the name STERAPORETM.

Their unique features:

  • Long service life (up to 15 years)
  • Energy-saving: 30% less energy consumption
  • Comfortable, simple, and can be designed based on the required amount
  • Suitable for design with variable quality inlet effluents
  • Performance stability at high turbidity (maximum 100NTU)
  • MITSUBISHI membranes are hollow-fiber, which take up less space than plate membranes.

Products

  1. PVDF membranes
  2. PE membranes

Advantages:

  1. A strong retaining layer causes the high durability of this membrane.
  2. High permeability
  3. High chemical resistance

Advantages of PVDF membrane module:

  • Saves time
  • Saves energy
  • Extensive range of products

Advantages of PVDF membrane element:

  • Easy transportation and storage in dry conditions
  • High packing density
  • More selectivity

As a result, PVDF membranes save energy, have a useful life, and increase the liquid-solid separation performance.

PVDF membrane module products:

a. Immersed membrane filter:

  1. Membrane modules are immersed in a tank to penetrate the filtered water with a suction pump or gravity filtration.
  2. Low pressure for water purification allows energy saving.
  3. PVDF membrane modules are used in a wide range of water treatment programs such as drinking water treatment programs or pre-treatment of drinking water and sewage, etc.
  4. Types of membrane modules in terms of capacity and height provide a lot of flexibility in system design.
