PRODUCTS

Water purification is used in various ways within most industries. IDENOR offers an ample range of alternatives to cover the needs of each customer, such as treating water that will be used as an ingredient of the process or the production of water for cleaning purposes or water of appropriate quality for certain services (boilers, cooling towers, etc.).

  • Multimedia Filtration:

This technology uses multiple layer filtration media, such as classified sand, anthracite, garnet, birm and many others. This equipment can be designed for automatic operation.+info

  • Activated Carbon Filtration:

It is used for the elimination of chlorine, color, odor and organic compounds. This equipment can be designed for automatic operation. +info

  • Bag Filtration:

Idenor carries an extensive line of GAF bag filtration products. GAF, a trademark from Eaton Filtration, is a worldwide leader in the development of this technology. These filters have been traditionally used for viscous fluids filtration (paint, ink, oils, resins, cataphoresis tanks, etc.) but recent advances in this technology have made its use possible for water filtration with high efficiency, even for very small particles (below 5 microns). Bag filters can be used efficiently for contents of suspended solids as high 0.1 %. +info

  • Cartridge Filtration:

An ample range of cartridge filters is commercialized by Idenor, with micron ratings starting at 50 microns and going as low as 0.2 microns. Cartridge filters are normally used up to a maximum of 0.01% of Total Suspended Solids. +info

  • Denitrification:

This equipment is based on ion exchange technologies and it is a possible solution for the problems derived from nitrates concentrations over 45 mg/l (as NO3-), which is the limit imposed by the World Health Organization (WHO) for potable water. Normally, this equipment is designed for automatic operation. +info

  • Reverse Osmosis (RO):

This membrane separation technology allows the elimination of most water contaminants, such as dissolved ions, organic compounds, colloidal matter, bacteria, virus, pyrogens, etc. It can be used for water for human consumption or for several industrial processes. +info

  • Bacwashable Microfiltration (MF) and Ultrafiltration (UF):

Both technologies are used for continuous filtration of water of high turbidity, such as superficial waters or certain industrial wastes. In both cases, the permeate turbidity can be below 0.1 NTU. MF is capable of handling higher influent turbidities than UF (over 50 NTU against 15 NTU), but UF also has the capability of stopping some organic compounds. +info

  • Continuous Electrodeionization (EDI):

This is a continuous process for water demineralization that uses ion exchange membranes and ion exchange resins. The resins are continuously regenerated by means of electric current instead of chemicals. Due to its physical characteristics, it is normally necessary to feed EDI with RO water, and is commonly used as a final polishing treatment by means of which it is possible to obtain water of very low conductivities (or high resistivities).+info

  • Nanofiltration (NF):

Similarly to RO, nanofiltration is a membrane separation technology used to purify water. The general rejection of these membranes is lower than that of RO, but they can be very useful for the production of drinking water, water recovery, softening and many other industrial processes. +info

  • Ultrafiltration (UF):

It is also a membrane separation technology but, unlike RO and NF, no dissolved salts are rejected; only suspended solids and organic compounds are rejected (its molecular weight depending on each particular membrane structure). This technology is widely used in some industrial processes, such as the dairy industry, wineries, etc. +info

  • Ozonation:

Ozone generation and injection is a very efficient method for microbiological control, both for process and drinking waters. Its powerful oxidizing power can kill bacteria in a few minutes and it is a very common technology in the beverage industry and, to a lesser extent, in the pharmaceutical industry. +info

  • Ultraviolet (UV) Radiation:

UV equipment is commonly used for killing bacteria and other microorganisms. It is also installed for TOC, ozone and chlorine destruction.+info

  • Heating and Cooling Systems:

Idenor has an Engineering Department that can design both heating and cooling systems, including a control system that covers all the customer needs. +info

    • Ion Exchange:

+info

  • Softening:

Idenor designs and constructs automatic softening equipment for all flows and sizes, single or multiple tanks systems, including a standard line of equipment for FRP tanks (8” to 36” tank diameters).

  • Deionization:

All possible combinations that use ion exchange resins are offered (two-column deionizers, mixed-bed deionizers or multiple-bed deionizers), both as standard or customized equipment.

  • Arsenic and Nitrates removal:

Idenor offers ion exchange equipment for removal of certain chemical contaminants like, for example, arsenic and nitrates, whenever this is the most convenient technology.

  • Dealcalinization:

Alkalinity reduction equipment that use cationic exchange resin (acid regenerated) can also be supplied by Idenor.

  • Decarbonation:

The elimination of carbon dioxide is many times necessary in several processes, such as reverse osmosis or ion exchange systems, both as pH control or to reduce the size of ion exchange tanks. Idenor designs and constructs equipment for this purpose: decarbonating columns or decarbonating membranes, the latter being used much more nowadays.

  • Waste Treatment Plants:

Idenor uses MBR, a state-of-the-art technology, to design compact and modular systems that can supply wastes of excellent quality for both sewage and industrial wastes. Designs that use this technology use up to five times less space than conventional technologies and supply a waste quality that can be treated by reverse osmosis and thus reclaim water for reuse. +info

  • Tertiary Wastes Recovery:

Ultrafiltration and MBR, together with reverse osmosis, can be also used to reclaim water from tertiary wastes. Idenor has participated in several of such important projects, especially in Brasil. +info

  • Chlorination Systems:

Idenor offers chlorination systems for all flows, starting from very simple low-cost designs up to highly monitored systems. +info

  • Pharmaceutical Compendial Water Generation, Storage and Distribution Systems:

Idenor has a remarkable experience in the design, construction, installation, validation and maintenance of pharmaceutical compendial waters (PW and WFI) systems, which comply with international regulations. In most cases, Idenor supplies “turn-key” complete systems, starting with the generation of the specific pharmaceutical water needed by the customer, its storage and, finally, its distribution to all the points of use (POU) in the production facility. In this process, all the Good Manufacturing Practice (GMP) procedures are followed. +info

  • Industrial Installations:

Although Idenor can perform industrial installations of most kinds, it specializes itself in stainless steel piping pharmaceutical systems. The latter includes the following tasks: detailed engineering of certified polished stainless steel piping installations using automatic orbital welding and the supply of all validation documentation. These processes cover the use of several technologies for maintaining the water microbiological quality, such as heat sanitization (usually at 80/85 °C) and sterilization (at 121 °C), ozonation, UV equipment or a combination of all these. +info

  • Potable Water Production (from superficial waters):

In this case, several purification methods can be used, which include traditional technologies (flocculation, sedimentation and filtration) or, more recently, other technologies such as hollow fiber microfiltration and bacwashable hollow fiber ultrafiltration. +info

  • Combined Technologies for Water Deionization:

The combination of technologies is widely use in water deionization (DI) for industry in general. The more common ones are: double-pass RO, RO+DI, RO+EDI. +info

  • Automatic Softening Plants:

Idenor designs and constructs efficient automatic softening plants, prepared to attend large demands of hardness-free water to feed boiler and cooling systems or any other industrial, commercial or residential demand where softened water is needed. +info
