The applications of reverse osmosis in non-food industries
Water filtration is a major component of various manufacturing and processing processes that require a specific saline and purity concentration of water. In agricultural farms, water filtration is a mandatory process that ensures that their produce complies with various food safety standards. This comes at a time when many industrial and home users are realizing that their publicly available water supply does not meet the high purity requirements that is should meet. Various water filtration techniques are available and reverse osmosis is one of them. The equipment for reverse osmosis comes in different sizes that can correspond to unique user needs. The following are the most common applications of reverse osmosis in industries other than the food industry.
Water treatment in boiler feed
Most companies that do boiler feed treatment rely on chemicals alone and are thus unable to offer the removal of dissolved minerals as part of their services. Unfortunately, without the removal of the dissolved minerals, clients cannot enjoy the benefits of reduced chemical consumption in boiler contents. Reverse osmosis when use in boiler feed treatment removes scale inhibitors and thus reduces chemical consumption. It also allows the boilers to use less energy because it reduces their blow down. When water boils into steam in boilers, it leaves scales that accumulate and causes damage when its concentration surpasses a given threshold. The reverse osmosis treatment reduces the accumulation by up to 98 percent.
The water used in pharmaceutical industry has to conform to a particular range of electrical conductivity to make it suitable for the drug making process. Research done on various reverse osmosis process adaptations to the treatment of ground water in the industry leads to a 99 percent retention of solutes so that the water passing through complies with the industry regulations. The same process also lowers the conductivity of water from 1770 micro Siemens per cm to just 15 micro Siemens per cm.
The $250 billion global semiconductor industry cannot survive without a sufficient supply of pure water. As the cost of doing business surges in various production centers in the world, companies are turning to their water filtration equipment to reduce expenses. The industry found a breakthrough in the use of reverse osmosis that led to significant cost reduction. The innovation was spearheaded by the National Semiconductor Ltd in Scotland that was able to combine the applications of reverse osmosis and electro-deionization phases that led to a water recovery percentage of 99 percent. Firms in the industry as now able to cut cumulatively their water consumption by about 40 million gallons while at the same time reduce their carbon footprint by a 200-ton margin.
Metal finishing procedures form part of the electroplating industry that consumes great amounts of water and produce one of the largest known volumes of liquid effluent. The control of the liquid waste is a critical factor in global environmental initiatives because the effluent has a devastating effect to animal and plant life. Reverse osmosis is a widely applicable solutions for the industry that enables firms to recover 75-90 percent of the water they use, in additional to a complete removal of any metal traces in they permeate that they release as waste.
