Beyond Microfiltration – Innovation In Industrial Wastewater

industrial water filters Membranes are changing the trajectory of wastewater treatment’s future. In the last 10 years been used for three decades. Membrane use responds to concerns about the tie of water and energy. They are more productive and occupy less space than the legacy operations they replace, similar to those using sand. Membranes are a success of which the material sciences can be proud. Anyway, membranes remove contaminants other treatment technologies do not. Seriously. Membrane markets can be divided into the well understood massmarket applications of spiral wound membranes, primarily for microfiltration, and complex, ‘custom engineering’ projects, sometimes involving hollowfiber membranes.

Organics; impurities, just like microorganisms; and suspended solids fed into the membrane element, In wastewater treatment for an industrial process, the feed solution is the input water containing ions. The concentrate or brine is water exiting the membrane, that contains the rejected impurities. Commercially available membranes efficiently filter particles down to the size of molecules or ions. As indicated by a January 2016 BCC Research report on global membrane markets, Membrane technology first came to maturity with the development of polymeric membranes. The BCC report’s authors say barriers to continued rapid microfiltration membrane growth include the growing use of ultrafiltration, membranes’ long lives and industry maturity. Essentially, the membranes for microfiltration or nanofiltration also have organics, solids and similar kinds of contaminants types, not simply salts. You should take this seriously. As indicated by Hanson, The other side of the market includes more challenging applications. Normally, the BCC analysts focus on two market spaces, bio pharmaceutical and industrial, including food and beverage. Industrial membrane filtration challenges include its reliance on government support for regulatory and environmental reasons and impact from the economic cycle.

Increasing interest in ‘industrial site’ water reclamation offers a growth avenue, and semiconductor and electronics manufacture demand increasing water purity. Microfiltration and ultrafiltration use lowpressure membranes, either in a pressure or immersed system, for suspended solids removal following secondary clarification. Microfiltration is often used upstream of RO systems that remove soluble materials from feed water. You see, microfiltration is a ‘lowpressure’ membrane process used to separate particulate from water down to sub micron and colloidal size, 1 to 05 micron. Certainly, while in line with a December 2015 report from Transparency Market Research on membrane markets to the year 2020, the primary criteria for selecting a suitable membrane include membrane thickness, either with homogenous or heterogeneous structure, and pore size. Membrane filters do not need expensive or ‘difficulttohandle’ absorbents or solvents, and the equipment is simple and modular.


industrial water filters Particle transport can be facilitated by pressure, concentration, chemical or electrical gradients in the membrane process.

The more salt that is present in the water, the more pressure required, and maintaining those pressures is very energy intensive, he said.

In a design environment focused on total life cycle costs, research on salt removal at lower pressures continues. Hanson sees GE continuing to invest in membrane technology, especially regarding low energy and robust membranes. That said, as indicated by Transparency Market Research, North America and Europe have the highest market demand for membrane filters because of their stringent environmental regulations. Continuing research and development into ‘high performance’ membranes for industrial gas processing is also increasing demand in these regions. The cost complexity of global water infrastructure water’s role in a sustainable, economic future.
