RO

Reverse Osmosis

.One of the most important products in this company is reverse osmosis package for treating water and wastewater

Since the development of the first practical cellulose acetate membrane in the early 1960s and the subsequent development of thin-film, composite membrane, the uses of reverse osmosis have expanded to include not only the traditional desalination process but also a wide variety of wastewater treatment applications. Several advantages of the RO process that make it particularly attractive for dilute aqueous wastewater treatment include:

  1. RO systems are simple to design and operate, have low maintenance requirements, and are modular in nature, making expansion of the systems easy
  2. Both inorganic and organic pollutants can be removed simultaneously by RO membrane process
  3. RO systems allow recovery/recycle of waste process streams with no effect on the material being recovered
  4. RO membrane systems often require less energy and offer lower capital and operating costs than many conventional treatment systems
  5. RO process can considerably reduce the volume of waste streams so that these can be treated more efficiently

Applications that have been reported for RO process in water & wastewater treatment packages of this company include the treatment of organic containing wastewater, wastewater from electroplating and metal finishing, pulp and paper, mining, petrochemical, textile, and food processing industries, radioactive wastewater, municipal wastewater and contaminated ground water and at the end RO membrane to be use for seawater and brackish water desalination a lot.

Nilfam Eng. co Comprehensive Range of RO Systems for Your Varying Treatment Needs.

The development and application of Reverse Osmosis (RO) to purify water began a few decades ago. In the older days, RO was primarily developed and used for desalination purposes for portable water, particularly in desert-related territories such as Asia, Middle East & African Region.

These days, with the advancement and decreasing costs of ro membrane and its application, ro technologies and processes have been applied to purify not just seawater, but highly contaminated or
brackish water for potable and industrial applications (or for industries requiring highly purified water)

Nilfam has a relatively long history in developing and integrating various types of ro systems for a wide spectrum of commercial and industrial applications in the region. Todey, we are a leading water company in manufacturing and distributing a comprehensive range of standard, modular and packaged (and custom-designed-and-bulit) ro systems including the following series:
