This module offers greater flexibility for designers of small filtration systems, particularly for commercial customers, and for applications where water demand is low, says the firm. It is most suitable for use in offices, hospitals, hotels or at the point-of-entry of a water supply for an entire house. Q-SEP 2008 is a self-encapsulated hollow- fibre UF membrane module that has a mem- brane surface area of 20.0 m 2 (about 215 ft 2 ). The total length of the unit, including the end- cap, is 1015 mm (40 inches), and it has a diam- eter of 225 mm (around 9 inches). It weighs 28 kg (about 62 lb). As with other Q-Sep mod- els this unit is mounted vertically. Q-SEP modules contain UF membranes that are manufactured using what the company refers to as its ‘cloud point precipitation’ method. This process ensures that there is a high pore density along the length of the fibre and a uniform pore size distribution in the membrane. Qua claims that Q-SEP modules deliver superior performance characteristics and prod- uct water quality, which surpasses the quality of water generated by conventional UF modules – with a low silt density index (SDI), and excel- lent rejection of bacteria and viruses. These modules are made from a hydrophilic polyethersulfone (PES) material that provides high fibre strength and excellent, low-fouling characteristics, which improves productivity. The membranes operate under low trans-membrane pressure in an inside–out flow configuration. The fibres are held firmly in place, which reduces the stress placed on them, even at high flow velocities. Uniform fibre packing limits the variation in pressure drop within the module and prevents localised, high fouling conditions. According to Qua, Q-SEP UF offers a num- ber of advantages compared with conventional media filtration. These include improved fil- trate quality; an SDI that is typically less than 1; the ability to remove virus, bacteria and microbiological, and colloidal matter; improved downstream RO performance; and consistent treated water quality, irrespective of changes in feed-water quality. In addition, for most appli- cations, the technology eliminates the need to add coagulant chemicals. Q-SEP UF modules can be used in dead-end filtration or in cross-flow mode. The mem- branes are available as 0.8-mm ID fibres, which are suitable for feed-water with low turbidity, and 1.2-mm ID fibres for applications involv- ing water with a high turbidity. These modules are designed for a range of uses, including pretreatment for reverse osmosis (RO) (brackish and sea-water), the purification of surface and well water for potable applica- tions, filtration of industrial water, and waste- water recycling and reuse.

Residential water treatment shows major growth in the developing world

A market research report produced by US-based Verify Markets shows

that the global residential water treat-ment (RWT) market is experiencing major growth in the developing world.

Entitled ‘Analysis on Select Global Residential Water Treatment Market’ the report, for 2012, says the the RWT market is dynamic and generated revenues of over $9.0 billion in 2011. The market varies by country and region. North America and Western Europe are mature markets, while Asia, Latin America and Eastern Europe are fast-growing ones.

In 2011, some of the largest markets were Japan, USA, China, Russia, India, Germany, France and South Korea. Most of these are dominated by local market participants and are fragmented.

The South Korean market is expected to grow at a compound annual growth rate (CAGR) of over 6% through the forecast period. In this country several companies sell and rent out water treatment systems. Several multinational companies are looking to enter the South Korean RWT market. LG entered the market in 2009 and has already established a significant pres-ence in this market place, says the study. Several companies use the direct selling method to sell water treatment systems and sell door to door. Some of the leading companies in South Korea include Woongjing Coway, Chungho Nais, Tong Yang Magic and Kyowon L&C. In South Korea point-of-use systems are highly popular.

The Chinese residential water-treatment market is expected to show tremendous growth with no signs of slowing down, says Verify Markets. Poor water quality, rising incomes and improved consumer awareness is driving the market.

In 2011, the Chinese RWT market garnered revenues of over $1.5 billion. The market is expected to show a double-digit growth rate through the forecast period. Some of the

key players in the Chinese market include Midea Group, Pentair, Ecowater, Shenzhen ChengDeLai, Ningbo Qinyuan, Shenzhen Angel Drinking Water Industrial Group Corp, Paragon Water Systems Inc and Litree.

Sales of water treatment systems were the high-est in Beijing, Shanghai, Guangzhou and Suzhou. The market is becoming highly competitive with several international companies entering the sec-tor. Most companies offer a diverse product line, such as point-of entry, point-of-use and pitcher systems. Some of the key international players include AO Smith, Pentair, Ecowater, Culligan, BWT, Panasonic and 3M. Several new entrants are likely to enter the market throughout the fore-cast period, says the firm.
