Filtration system OF R.O Plant

Industrial Filters
Environmental solutions company Procon Environmental Technologies has delivered one of its Glando filtration units to a water treatment plant at South African ferro-chrome producer Samancor Chromes Tubatse Ferro-chrome smelting operation, in Steelpoort, Mpumalanga province. Tubaste engineering manager Chirag Patel says that the Glando Industrial Filters technique is adding significant value to the plant as it provides protection against damage to the pricey reverse-osmosis membranes used to desalinate the process water. The plant processes up to five-million litres a day of which 50% to 60% will pass through the Glando units.

An additional filtration technique was necessary at the plant to prolong the life of the reverse-osmosis technique Industrial Filters is used for water treatment. The plant aims to treat water to industrial standards, but the pricey reverse-osmosis technique cannot tolerate hydrocarbons in the feed water. Filtration unit will run at the plant together with industrial water treatment company Water Services ultra filtration & reverse-osmosis systems. The ultra filtration system will remove all solids in the coursework of the first stage of treatment, after which the water will pass through the Glando filtration unit, which removes hydrocarbons from the water before it is pumped through the reverse-osmosis system to be desalinated. There are two sets of filters at each stage of the process and one filter is in use while the other is on standby. Industrial Filters removes 99,9% of hydrocarbons to meet sewage and stormwater discharge limits. It has ISO 9001: 2000 certification and meets a standard of one part per million, or less, for oil removal.

The company indicates that the National Water Act requires filtration to reduce oil and grease levels to below 2,5 mg to be potable and that the Glando adequately meets this requirement. Further, the technology provides a low life-cycle cost as it absorbs ten times the amount of oils than other technologies, including activated carbon. Technology is a green manufacturing process with no waste generation. He adds that the company has seen a significant increase in interest in filtration systems, such as the Industrial Filters, in the past three to four years, as industries are becoming increasingly aware of the environmental impact of their processes.

We have seen an increase in environmental concerns because there is also a significant need to recycle and reuse water. This has picked up dramatically over the past few years. Procon reports that the Glando technology process is environment friendly as it results in the permanent removal of oil from process water, has low energy consumption levels during filtration and has no sludge or oily water waste by Industrial Filters. The used Glando Industrial Filters cartridges can be disposed of as hazardous waste or used in the boiler start-up process.
