Ion exchange resins
Cleaning of drains
The lack of clean water today has become the most pressing global problem of mankind, which has a serious impact on human health.
Population growth, air pollution, water pollution, and global climate change continue to worsen the current situation, especially in metropolitan areas, where available clean water resources need to be carefully monitored.
We offer a variety of products and solutions to meet the growing needs of people for clean drinking water free from harmful impurities.
Cleaning of drains
The treatment of industrial wastewater or the removal of toxic, ionic, and non-ionic substances from wastewater has become today a key task for all, without exception, industries with which a person is somehow connected.
We offer a wide range of special ion exchange resins and Lewatit ® adsorbents, which are highly effective in cleaning processes from heavy metals, toxic impurities, and organic contaminants.
Due to the high selectivity, achieving extremely low residual concentrations of pollutants in the effluent becomes economically justified.
The use of ion-exchange resins provides significant cost savings by minimizing wastewater volumes or even organizing a closed production. In addition, thanks to ion-exchange resins, it is possible to organize the extraction of valuable components, in particular, precious metals from effluents for their reuse.
Ion exchange resin catalysts are among the most versatile catalysts used in industrial organic synthesis.
The possibility of a wide variation of the polymer structure of the matrix and functional groups makes their use in this capacity quite attractive and flexible.
Most of the ion exchange resins used as industrial catalysts are sulfonated styrene-divinylbenzene copolymers.
At present, the share of hydrometallurgical schemes for processing mineral raw materials in the total number of developed technologies is increasing. The basis of this trend lies in the flexibility, versatility, and independence of hydrometallurgical processes from the composition of raw materials, which cannot be said about pyrometallurgical technologies.
We offer a wide range of ion exchange resins for hydrometallurgical processes, whether it is the selective recovery of a specific metal or the separation of two metals with similar properties.
The use of hydrometallurgical processes with the use of ion-exchange resins also makes it possible to involve in the processing of depleted resource base reserves, as well as man-made waste, which is an inevitable consequence of decades of intensive mine operation. These technogenic resources are an important additional source of valuable components, the processing of which by traditional methods is unprofitable and requires the use of innovative methods, which is, incl. sorption using ion exchange resins.
For tasks when not selective extraction of certain impurities is required, but complete water demineralization, we offer Lewabrane® reverse osmosis membrane elements, which allow obtaining demineralized water from low-quality water that meets the requirements of world drinking standards.
Solution for technical water
If general water purification is required, and not the selective removal of certain compounds, then using Lewabrane® reverse osmosis membrane elements can effectively solve the problem. In addition to the high selectivity of membranes for organics and salts, a wide range of Lewabrane® membrane elements are offered to achieve optimum selectivity and operating pressure.

Ion exchange resins are widely used in filters of water purification systems at the stage of water treatment in industrial enterprises. Externally, the ion exchange resin looks like a cluster of small balls, the diameter of which does not exceed a millimeter. The material for making these balls is special polymers. The resin for the filter can trap ions of various impurities (from metals to hardness salts), replacing them with safe and harmless ions of other substances. Ion exchange takes place. An ion-exchange filter is a housing device for removing unwanted ions from aqueous solutions. Like any filter, it extracts and removes the unwanted from the real. The water passing through it is freed from the ions of various compounds that pollute the water. Softening, demineralization, and purification of water are the main tasks that an ion exchange filter solves.
Reverse osmosis equipment is designed to purify water by separating mineral salts, organic substances, micro-impurities, and bacterial contaminants through a membrane. The essence of reverse osmosis is the passage of water containing mineral salts, organic matter, bacteria, and micro-impurities under pressure through special semi-permeable membranes. In this case, the reverse osmosis membrane allows only water molecules to pass through, trapping impurities. The result of the process is purified and demineralized water and water with concentrated impurities. The distinctive features of this method are purification of water from bacteria and pyrogens, low operating costs, electronic quality control due to production automation.
A reliable and effective way to free water from suspensions, colloidal solutions, and organics without affecting the salt ratio is the use of a water ultrafiltration system. The technique is based on the use of complex membrane structures with pore diameters in the range of 0.1—0.01 microns. The plants are used for the production of clean drinking water on an industrial scale. When used in production, it can also be used as a preparatory treatment before supplying liquid to softening systems, filtration in nanofiltration plants, or operating on the principle of reverse osmosis.
Installation of an ultrafiltration system will allow, after passing through the water, to achieve the following values:
suspension content in the sample after the system is less than a milligram per liter;
measuring the turbidity index using the kaolin scale – less than 0.1 milligram per liter;
analysis for saturation with ions Fe³ + – less than 0.1 milligram per liter;
measurement of permanganate oxidizability – less than five milligrams per liter;
the absence of 99.9% of microbiological organisms from the initial water intake.

Disk filters for mechanical water purification are used as coarse primary filters and mud collectors in various industries. Such filters are used in water treatment and water purification systems, water mains, and cooling systems. Thanks to disc filters, heat exchangers and cooling towers are protected from mechanical impurities. The process of water purification on disc filters is based on the passage of water through lamellar discs collected on a telescopic core, which provides a high degree of filtration.
During the filtration process, the lamellar discs are tightly compressed against each other, ensuring high filtration efficiency. Water flows through the filter element from outside to inside. Solids remain between the discs and on the inside of the discs, and the treated water exits through the outlet. Disc filters are easy to install and maintain. The gradual accumulation of impurity particles on the discs leads to a pressure drop, the value of which is monitored by the sensor, after which an automatic self-cleaning cycle begins. Cleaning of the disc element is performed by backwashing at the time of the separation of the discs on the telescopic mandrel.
Reagent water treatment
In technological schemes of water purification (surface, underground, or wastewater), reagent water treatment processes are used, which are carried out by means of a chemical substance into the treated water in order to change the water quality indicator to the required value. To eliminate the turbidity and color of water and reduce the intensity of tastes and odors of water, a coagulation process is used. There is a physicochemical process of agglomeration of the smallest colloidal and dispersed particles under the influence of forces of molecular attraction as a result of the action of mineral salts with hydrolyzing cations on them. As such salts, aluminum and iron salts are used, as well as their mixtures in various proportions. A variation of the coagulation process is the flocculation process, in which small particles suspended under the influence of specially added flocculant substances form loose flocculent accumulations of floccules. One of the flocculants is polysilicon acid and polyacrylamide, and the most effective are soluble polymers, polyelectrolytes. Both of these processes are used at the preliminary stages of water purification and are basic for the complete or partial correction of the characteristics of surface waters caused by the most inert impurities or living organisms. They also ensure the removal of the “flocculated” part of organic substances: macromolecules, humic acids, tannins, and lignins, which impart color to water.
Backfill water treatment systems
Backfill water treatment systems are manufactured with an automatic control unit. Disc filters for coarse water purification are most often installed in front of the inlet filters. The principle of operation of the filling filter the treated water through the inlet pipe is supplied under pressure to the filter, passes from top to bottom through the layer of filtering material and, after being cleaned, through the lower nozzle enters the riser pipe, through which it rises up to the outlet port. During operation, filters for water purification of the filling type become contaminated, therefore, they must be periodically washed or restored (regenerated). Regeneration is mainly used for ion-exchange or catalytic filters of the filling type since it allows the most complete restoration of the oxidizing capacity of the catalytic load or cation exchanger. Regeneration of water filters, as a rule, includes three stages: backwashing, treatment of the filter material with a reagent, and direct washing. When using chemical regeneration of the filter medium, the stages of this regeneration can be more, since auxiliary processes are added: replenishment of the reagent tank with water, additional loosening of the filter layer.
