1. Establish the quality of raw, untreated water

The chemical composition of freshwater drawn from wells, reservoirs or directly from power systems vary considerably regarding the quantity and variety of dissolved minerals and particulates. Cost-effective purification systems are now available that can handle the local hard or soft water and deal with the inevitable fluctuations in resource quality.

For example, sand and multi-media filters such as the best reverse osmosis system proved to be very active in food and drink production by eliminating particles, while the activated carbon adsorption systems allow the removal of organic contaminants and chlorine compounds which can color an impact, taste, and smell. Depending on the nature of the raw water, however, it may be necessary to protect pre-treat feed stream elements of the chosen water purification system – for example, a reverse osmosis membrane – in particular in areas where the feed water contains high levels of organic pollution, hardness, and free chlorine.

2. Determine the quality and purity of the water is needed

In fact, not only take into account the degree of purity is required, but also whether that quality throughout your entire system is necessary. Various levels of purity required different areas? There are three degrees of purity of the water that are standardized. Grade 1 represents the highest degree of purity, 0.01mS / m (0.1μs / cm), with the rank 2 being 0.1ms / cm (1μs / cm) and Grade 3 on a level of 0.5mS / m (5μs / cm) . Not all water purification systems can deliver all three of these figures. For example, distilled water, or on-site distillation units can only supply water usually to grade 2 standards at best. Disposable ionization or ion exchangers which can be connected to mains can supply the rank first stream of purified water, but may not be profitable if the feed water contains a high content of dissolved solids and the demand for purified water is more than 10 -20 liter per day. Reverse Osmosis, however, is feeding water under pressure into a module containing one or more semi-permeable membranes. The process removes up to 98% of inorganic ions, as well as virtually all colloids, microorganisms, endotoxins, and macromolecules. These membrane elements are constantly improved to high currents at lower operating pressures. This has included the development of ultra-thin spiral wound membrane layers – made of polyamide thin film composites nonwoven polyester support webs – are just 120microns thick.

3. Taking into account the specific requirements of your business

Food and beverage manufacturers must meet the necessary hygiene and safety standards for their respective companies while the purity of the water is particularly important in laboratories. As an alternative to resin-based deionization systems, the larger integrated reverse osmosis systems can be an electro-ionization system (EDI), which is provided with – a combination of ion-exchange membranes/resin and electricity to the water deionise – produces water with a quality greater than 10 MΩ .cm. Where Grade 1 of water with an improved microbiological quality is required, the RO / deionized purified water is further processed with the aid of UV-irradiation at 254nm and sub-micron filtration between 0:05 and 0.2 microns to remove bacteria and particulate matter.

4. Remember these other factors

How much water do you need? What are the patterns of daily use, the peaks, and valleys? And how do you make a system that meets these requirements without selecting excessive financial demands on installation, maintenance, and operating costs? British brewing industry, for example, uses an estimated 34 million cubic meters of water per year. For each liter of producing beer, the amount of water necessary up to six times, the volume required for the process far above that of the final product.

Distillation systems are still used as agents for the production of purified water. A process that has been in existence for hundreds of years, the practice of the boiling water to create steam – thus leaving behind these impurities having a boiling point higher than that of water – is a hot, inefficient system for the production of purified water, which regular maintenance and high running costs.

Reverse osmosis water treatment systems are capable of achieving high levels of constant purity with correspondingly high volume.

5. Neither under nor overestimate your needs

A common cause of inefficiency in water treatment plants is oversizing. Oversized systems require additional space, increased costs, and – like systems such as reverse osmosis may be less effective if only operational for a short period – can suffer degraded performance. Similarly, should be a realistic estimate to be made of the number of take-off points which will be in use at any given time, but if it is simply being adopted during the installation will that all the points will be utilized at one time, it may be due to a drastically too vast and expensive system. Reverse osmosis water purification systems not only reduce energy consumption but also, thanks to the advanced membrane technology (such as the creation of a much higher active membrane surface), can help you reduce the total number of modules in larger systems, thereby cutting capital and maintenance costs Furthermore.
