The ORGASORB inside biofilters are adsorbent and are dedicated to polishing the water.

For this reason, we always place them at the end of the water lines, as a TERTIARY TREATMENT.

By generic adsorption (cation exchange and chelation), the INTENSIVE ORGASORB water biofiltration solution results in optimal efficiency from:

✓ turbidity <30NTU | <10 NTU for reuse

✓ temperature <50°C

✓ 4 < pH < 11

✓ Salinity <12mg/L

✓ a contact time calculated according to the exact efficiency required for the purpose of water use.

Therefore, who can more, can less.

Chelation is a type of bonding of ions and molecules to metal ions. It involves the formation or presence of two or more separate coordinate bonds between a polydentate (multiple bonded) ligand and a single central metal atom.[1][2] These ligands are called chelants, chelators, chelating agents, or sequestering agents.

This Chemisorption is achieved usually by organic compounds,. ORGASORB inside mat is also a chelating agent (pesticids, drugs etc).

We can also combine o mix it to make relevants and personnalized multimedia intensive biofilters.

Ion exchange is a physical process where basically ions (cations + or anions -) remain attached to functional groups on the surface of a solid.

This physisorption is achieved through the use of adsorbent materials such as resins, zeolites, or the ORGASORB inside mat.

We can also combine o mix it to make relevants and personnalized multimedia intensive biofilters.

1. Las resinas de intercambio iónico cuentan con la capacidad de eliminar iones selectivamente, por medio del fenómeno explicado anteriormente, y posteriormente cederlos a una solución fuerte de regenerante. Estos cationes indeseables – metales pesados, nobles o metaloides – presentes en las aguas normalmente son intercambiados por sodio, hidrogeno y otro tipo de iones que se encuentran presentes en estas resinas.Las nuevas resinas de intercambio iónico, con fin de sustituir a las originales (zeolitas), surgiendo así resinas sintéticas como el estireno y divinil-benceno (DVB).
   Estas nuevas resinas son básicamente polímeros insolubles a los cuales se añaden grupos básicos o ácidos mediante reacciones químicas. La adición de estos grupos permite al polímero o le da la característica de poder realizar un intercambio reversible con los iones que se encuentren presentes en una disolución.
   La figura 1 muestra los dos tipos de resinas utilizadas, sintéticas (polímeros) y naturales (zeolita).
   Estas resinas son reutilizables, lavándolas con una solución de sal común para eliminar calcio y magnesio, restaurando la condición original de la resina.
   Debido a la eficiencia en la fijación de cierto tipo de iones contaminantes, este procedimiento se ha implementado en los últimos años como una alternativa importante en el campo del tratamiento de aguas residuales.
2. Las Zeolitas: Inicialmente utilizadas en los procesos de intercambio iónico, las zeolitas – minerales naturales adsorbentes -, las cuales siguen poniendo limites en cuanto a las aplicaciones que se pudieran dar a este tipo de procesos por su capacidad de adsorción baja.

1. Ion exchange resins have the ability to selectively remove ions, by means of the phenomenon explained above, and subsequently transfer them to a strong regenerant solution.
   The new ion exchange resins, in order to replace the original ones (zeolites), thus giving rise to synthetic resins such as styrene and divinyl-benzene (DVB).
   These new resins are basically insoluble polymers to which basic or acid groups are added through chemical reactions.
   These resins are reusable, washing them with a common salt solution to remove calcium and magnesium, restoring the original condition of the resin but generating a highly charged and polluting effluent.
2. Zeolites: Initially used in ion exchange processes, zeolites – adsorbent natural minerals -, which continue to limit the applications that could be given to this type of process due to their low adsorption capacity.
3. Reverse Osmosis filtration is a process in which a balance is generated between the molecules present in a solvent, which are capable of passing through a permeable membrane – with pores of a size of 0.0001µ – in order to dilute a solution. more concentrated. In wastewater treatment, the contaminated effluent is brought into contact with a membrane at a pressure higher than the osmotic pressure of the solution. Under these conditions, water with a very small amount of contaminants passes through a membrane. Dissolved contaminants concentrate in the wastewater compartment, the reject water or concentrate which can reach 50% of the supply water. This concentrate, which is possibly a fraction of the total volume of wastewater to be treated, is discharged and generates some pollution if it is not decontaminated for recycling. In return. purified water is obtained in the other compartment. Figure 3 represents three types of osmosis system, the first refers to direct osmosis, the second represents the equilibrium condition and the third represents when a pressure higher than the osmotic pressure is applied.In practice, the wastewater flows at high pressure through internal tubes, which belong to the tubular configuration systems used in this process, made up of semi-permeable materials that withstand high pressures; The purified water is separated in the outer tube which is made of common materials and is at atmospheric pressure.
4. Chemical Oxidation by chlorination and/or ozonation: Chemical oxidation is a process in which the oxidation state of an atom is increased. The atom being oxidized can be in the elemental form or in a substance as a molecule or as an ion. Within the chemical oxidation processes are chlorination and ozonation, which are the best known for their efficiency in this field of water treatment. The chlorination process is widely used in the treatment of both industrial and urban effluents. Among the applications at the industrial level are the treatment of discharges from petrochemical industries, textile pharmaceuticals, sugar cane plants, among others. Among the objectives of the chlorination process are the oxidation of certain metallic ions (for example, from ferrous to ferric), the oxidation of cyanides to innocuous products, the elimination of colors and odors, the reduction of biological oxygen demand (BOD) and the Last and most important due to its properties (speaking of chlorine) is the disinfection caused thanks to the strong oxidation capacity that inhibits the growth of algae and bacteria in the water. As we have seen, chlorine is or was the most widely used reagent for oxidation purposes, but due to organoleptic drawbacks and the growing complexity of its use due to interferences caused by other substances in the water, the ozonization process has taken more strength. Ozone, unlike other types of oxidizing reagents, has the advantage of destroying micro-pollutants, improving flavors and odors and removing color. Among the factors that have made ozone very popular as an oxidizing compound is that it easily facilitates unsaturated organic products found in water, tends to eliminate the formation of foam in wastewater, breaks and oxidizes rings aromatic and last and most important is that after its oxidation reactions, ozone becomes oxygen in the water, unlike other oxidants such as chlorine that only remain as a contaminant in them.

5. Adsorption on activated carbon: Activated carbon is a term that covers a very wide range of amorphous carbonaceous materials which have high levels of porosity and an extended surface area. These activated carbons can be obtained by either rapid or partial pyrolysis of a large number of carbonaceous materials or substances. As mentioned above, carbonaceous raw materials such as wood, lignin, coal and walnut shells are among the preparation materials for carbons. Activated carbon also, thanks to the aforementioned properties, is a unique material in terms of adsorption of liquids and gases, which gives it a privileged place in terms of producing clean environments that involves water purification processes and separation and purification in the chemical industries. Regarding the treatment of wastewater, adsorption by activated carbon is used when the effluent contains toxic organic compounds that can prevent biological purification (biodegradation), in addition, activated carbon, as mentioned above, has a high internal surface (between 500 and 1500 m2/ g) and presents a great variety of functional groups in its organization that help and make it ideal for the adsorption process. Activated carbon also, thanks to its graphite structure, can store elements such as oxygen, nitrogen and hydrogen in its vertices and edges. Within the range of adsorbents that exist (silica gel, alumina, activated carbon, etc.), activated carbon is usually the most used thanks to its high adsorption capacity for low molecular weight polluting organic compounds such as phenol. Some of the contaminating compounds of water effectively eliminated by activated carbons are presented in table 2 described by the author Oscar Martínez.
   Recently, the activated carbons that have been used more deeply in the water treatment industry have been granular and powdered, this in order to eliminate odors and taste is that they can produce certain contaminants. One of the advantages of activated carbons over other treatment methods is the power they present for reuse, this, as John Happel mentions, is achieved by strongly heating the carbon in the presence of steam in ovens designed for this purpose. After this, the carbon can be returned to its work either in adsorption columns or other means. Going into detail about the coal reactivation process, it is achieved by means of temperatures of up to 930ºC in multiple hearth furnaces or rotary kilns, allowing the reactivation of the coal up to 30 times. The phenomenon that explains the capacity of “cleaning”, desorption or reactivation of carbons is explained by Walter J. Weber where in the type of physical adsorption, the adsorbed molecule is not fixed in a specific place on the surface, which allows it to be free and move within the interface, since the adsorption of most organic substances in the water with activated carbon is considered to be of a physical nature. When the adsorbate undergoes a chemical interaction with the adsorbent, the phenomenon is known as chemical adsorption, active adsorption, or simply chemisorption. In the case of chemisorption, the adsorption energies are high, on the order of those of a chemical bond, because the adsorbate breaks and forms strong bonds located in the active centers of the adsorbent. In most adsorption phenomena these two phenomena usually occur, where in fact there is a level of difficulty in distinguishing between chemical and physical adsorption. In the case of carbon, the force used by the atoms on its surface to capture other atoms is known as the London force and is one of the types of van der Waals forces capable of retaining one more atom but not so strong as to form irreversible bonds. In the adsorption process, the elimination percentages depend fundamentally on the contact time between the residual water and the activated carbon. In physical adsorption studies, the most relevant experimental information is presented in the form of the adsorption isotherm, which is a graph of the equilibrium quantities adsorbed against the relative pressure or more precisely the equilibrium ratio between adsorbent and adsorbate. It is necessary not to focus on the adsorption results thrown by the computer equipment, instead it is preferable to use the manual points and the knowledge of the adsorption processes to carry out the isotherm.

6. Generic adsorption by ORGASORB inside mat. 100% vegetable mat, its implementation is very similar to activated carbon filtration but the fluid mechanics responds more to membrane purification work than to granular media (resin or activated carbon). Regarding its adsorption, it combines physisorption by cation exchange (radionuclides, metals and metalloids) and chemisorption by chelation [H+] (complex organic molecules such as pesticides, herbicides and some drugs). That is why we decided to speak of generic adsorption for capturing in an inert and irreversible way a wide spectrum of dissolved contaminants. Its plant composition allows for an eco-responsible transformation or final disposal as well as being an adsorbent medium from a CO2 sink, the largest artificial forest in Europe. In short, it works with a higher efficiency, spectrum and adsorption capacity than activated carbon while it did not receive any treatment with a contaminant footprint:
