Membranes & Reverse Osmosis


Membranes, Reverse Osmosis Design & Supply

Process Fabrications Ltd. Reverse Osmosis (RO) elements are ideal for the majority of demineralised water production for a range of municipal water sources, their construction suits a broad range of chemical, temperature and pressure applications.

The spiral design allows higher membrane areas within a given envelope than other current arrangements. They are energy efficient, compact and economical to install, allowing maximum operating flexibility for most filtration processes, The spiral wound elements and housings, offered are available in 1.8″, 2.5″, 4″, 6″ and 8″ diameters, all in industry standard lengths.

The Process Fabrications Ltd. Reverse Osmosis (RO) filtration systems have been designed to assist in the efficient production of clean water from industrial waste water recycling, effluent plants and desalination systems in a multitude of industries; petrochemical, chemical, food & beverage and pharmaceutical.
The benefits of the use of these filtration systems include; a reduction in operational expenditure (OpEx), smaller footprint, minimal operation and maintenance requirements, all aiding in a reduction of disposal costs via reuse.

Process Fabrications Ltd. not only offers a full, bespoke, design and build for the system to suit each customer’s requirements, but can also provide a comprehensive service and maintenance package along with a tailored financing solution.

A RO system is a method of producing pure water via raw water passing through a semi-permeable membrane in a direction opposite to that for natural osmosis when it is subjected to a hydrostatic pressure greater than the osmotic pressure.

RO is used for water filtration in a wide range of applications including desalination of seawater and in the production of demineralised water for use in other applications, such as component rinse systems prior to a coating process. The semi-permeable membrane employed for reverse osmosis is capable of rejecting 99.9% of bacteria and is therefore used frequently in the design of pharmaceutical pure water systems.

Process Fabrications Ltd. offer a wide range of reverse osmosis plants and replacement membranes, along with a wide range of pre-treatment equipment including softeners, activated carbon filters, and multi-media filters.

A complete product range is available from single RO systems to accommodate 150l/h right up to those capable of 50,000l/h with all the associated pre and post equipment from filters to storage tanks and the interconnecting pipework.
