Textile wastewater treatment plant is re-equipped with X-Flow membranes
Pentair X-Flow has re-equipped Go Go International Pvt Ltd’s textile
wastewater treatment plant, based in Hassan, Karnataka, India, with its Aquaflex 55 ultrafiltration (UF) mem-brane modules.
After the original membranes failed repeat-edly, the clothing manufacturer decided to change them and chose X-Flow’s Aquaflex 55 to achieve the designed water quality and quantity.
The membranes are used to provide opti-mum pretreatment for a reverse osmosis unit. According to Pentair X-Flow, they have out-standing anti-fouling properties and deliver consistent separation performance, with low energy consumption.
The use of Aquaflex 55 has lowered turbidity from 10 NTU to less than 0.1 NTU, says the company. Colour is removed and the designed permeate flow rate of 40 m3/h is achieved at a feed-pressure of 0.03 MPa (0.3 bar).
Go Go International uses the treated water as process water for textile dyeing purposes.

Filter combines cross-flow filtration with centrifugal separation
Dow Water & Process Solutions (DW & PS), a business unit of Dow
Chemical Co, has launched the Tequatic Plus fine particle filter, which has been developed for use in demanding water environments.
With its patented design, the filter combines the power of continuously cleaning, cross-flow filtration with centrifugal separation, in single device, which is specifically designed to handle difficult-to-treat feed-water more consistently and cost-effectively than traditional technolo-gies, says the company.
The filter is produced by Clean Filtration Technologies Llc (CFT), which became a wholly owned subsidiary of Dow in April 2012.
According to Cedella Beazley, General Manager, CFT, this filter represents a breakthrough in that it is able to tackle applications involving difficult-to-treat water – reliably handling high and highly variable total suspended solids (TSS).
‘Working together, CFT and Dow have accelerated technology development to an unprecedented level, resulting in an early mar-ket introduction of this exciting system,’ com-mented Beazley.
‘By adding the Tequatic Plus filter to its line-up, DW & PS can now meet needs for fine particle filtration, continuing its commitment to offering customers the most complete portfo-lio of advanced water purification technology.’
John Patrin, Strategic Marketing Manager, CFT, added: ‘It has the ability to filter water with high and variable solids with almost no maintenance, fouling and back-wash cycles, and there is no need for cartridge filters. This adds up to lower maintenance and consumables costs, and high uptime – all of which contrib-ute to a lower cost of ownership.’
Patrin also cites several environmental and safety advantages for customers looking to enhance the sustainability of their operations.
He said: ‘The Tequatic Plus filter requires minimal filter changes and chemicals, which minimises handling hazards and disposal, help-ing to reduce the impact on the environment.’
Applications include pretreatment for ultra-filtration and reverse osmosis, and filtration of produced water in the oil and gas sector. The product can be used as an alternative to (or a complement) traditional filtration technologies. It is currently available in various flow rates with filter cut-offs of 10–55 μm to meet specific cus-tomer needs.
‘Looking ahead, the CFT team already has in development the next generation of technology for the Tequatic Plus filter – with the goal of providing customers with a full suite of innova-tive particle filtration technologies for difficult-to-treat feed-water,’ concluded Beazley.
