ION-EXCHANGE RESINS : QUALITY BASED SOLUTION FOR DECONTAMINATION

Ion exchange resins remove dissolved ionic contaminants from liquids. Therefore, functional groups are attached to the polymer beads. Water treatment is one of the major fields of application for ion exchange resins. It is particularly utilized as a water softening agent. It ensures that the calcium ions responsible for water hardness are replaced by sodium ions. It is used in large scale industry such as power generation as well as in the production of ultra-pure boiler feed water and steam to avoid incrustations and corrosion. This improves the efficiency, lifetime of power plants and operation credibility.

Resulting removal of toxic substances due to the utilization of ion-exchange resins,  plays a vital role in cleaning of industrial effluent and treatment of groundwater. Alongside, it is also used in other fields of application such as semiconductor production, galvanic industry (recovery and treatment of metals such as gold, copper, nickel or cobalt in hydrometallurgy), pharmaceuticals, and the food and beverage industry.

In the production of crystal sugar and liquid sugar syrup, it enhances the brown cane sugar to be turned into the attractive white product and ensures that sugar also tastes like sugar. Ion exchange resins are also reliable catalysts which are crucial for many chemical reactions.

As per individual industrial requirements and uses, ion-exchange resins are categorized as follows:

Mixed Bed Resin

Mixed Bed (MB) Resin is a resulting mixture of cation and anion exchange resins. They are used as polishers to attain low conductivity water, which is required for boiler feed for high-pressure boilers, electronics and electrical discharge cutting machines and pharmaceutical applications.

Mixed bed polishers are utilized as a primary deionisation unit when the salt load is low. They are used in process industry, where demineralisation of pH sensitive products is exhibited. Depending upon the requirements, MB grade resins are applied in custom-designed ratios.

Mixed bed resins are mainly used in the water purification industry for treating process water to achieve demineralized water quality such as after reverse osmosis system.

Its typical applications include:

  • Ultra pure water production
  • Demineralisation
  • Condensate polishing (boiler feed water)
  • Micro-electronics cleaning
  • Pharmaceuticals

Super Charged Resin

Super charged resins are used in highly regenerated, premixed conditions for use in multiple applications such as dye applications, pharma, metal separation etc. They are available as highly regenerated cations and anions for their utilization in regenerable mixed bed units. Premixed resins are compatible to work in different proportions and combinations of cations and anions to attain user and process requirements.

Super charged resin is especially suitable to use in mixed bed units for further filtration after primary demineralization systems in process industries, electronic industries, small industrial plants etc.

DM Plant Resin

Demineralization is performed with help of ION Exchange, RO, and electrodialysis. RO and electrodialysis are performed to remove the dissolved solids with the help of membrane process whereas Ion exchange is softening process which is mostly used to remove the hard minerals such as calcium, magnesium from the water or wastewater. In this process, Hydrogen (H+) and Hydroxide (OH-) are used to exchange the negative and positive ions.

Cooling Tower Maintenance Chemicals – High Performance & Quality Based Chemicals

Cooling towers are used for heat rejection in industries, where water is cooled down, and air draft is achieved with the help of draft towers and fans.

Feed water to be cooled down in the process, may have temperature between 40 to 60°C and with the contact of above air flow, its temperature is decreased between 10 to 20°C. This entire process is based on natural evaporation of water as after being cooled, water is again recirculated into the production process.

Cooling towers are structured as open and closed systems. In a closed cooling tower system, the water does not come in contact with outside air. So, it prevents any deterioration from outside air pollutants and microorganisms to the cooling tower system, but alongside, it also hinders the execution of some microorganisms inside the system, due to no contact with outside air. it is vice versa for open cooling tower system.

The efficiency of cooling towers is affected due to some disruptions such as scale and slime formation, corrosion, biological-fouling etc, as water is cooled primarily by evaporation of a portion of the circulating water and airborne impurities such as dust and gases, may enter during the process. This affects system efficiency badly as well as shortens cooling towers’ life expectancy. In order to enhance the efficiency of the system, and prevent forementioned disruptions to the process, several chemical additives are used.

Acuro Organics Limited offers ACUCOOL range of cooling tower chemicals, focusing on multiple application processes as follows.

  • Antiscalants
  • Descaling agents
  • Corrosion inhibitors
  • Biocides
  • Biodispersants

Polyelectrolytes – High Molecular Weight Flocculant Polymers

Polyelectrolytes are chemicals that have qualities and characteristics of both polymers and electrolytes. For instance, polyelectrolytes have the properties of higher viscosity, that is adopted from polymers and higher conductivity is adopted from electrolytes(salts).

Applications

Polyelectrolytes have multiple applications:

  • Polyelectrolytes are mainly used in water treatment processes, we can use them in water-treatment for sediment settling, and solid-liquid separation.
  • In chemical reactions, polyelectrolytes are used as thickeners, emulsifiers and conditioners for influencing any reactants in any particular reaction.
  • In daily life, we can find them in cosmetics, shampoos and soaps.

Types of polyelectrolytes on the basis of applications:

We can categorize polyelectrolytes in three categories:

  • Cationic Polyelectrolytes working as coagulants are used to neutralize the negative charge present on wastewater particles. In this process cationic polyelectrolytes are considered as primary coagulants, as they have a large scope to work, especially dewatering processes and for bio sludge sedimentation.
  • Anionic Polyelectrolytes, bearing negative charge, are adequately efficient for process applications like paper, sugar, textile, mining & food industries.
  • Non-ionic polyelectrolytes don’t consist of any specific charge unlike above mentioned. They are chargeless, but capable enough to work with a compatible composition of water.

Working of Polyelectrolytes

Polyelectrolytes with high molecular weights form bridges with wastewater materials. This phenomena is called coagulation bridging phenomenon. Polyelectrolytes also work as flocculants, they create bridges along the suspended particles or sediments and anionic or non-ioinic polymers, and widen or maximize their size so they settle down in the solution all together.

Activated Carbon – Highly Advanced Material For Water Treatment

In order to overcome the dilemmas of water purification, microbial inactivation, separation and purification of chemical-allied industries, Activated Carbon (AC) is the significant solution. AC has accelerated the remarkable development and expansion of Carbon Science and Nanotechnology in recent years.

It is a highly porous, carbonaceous material produced by carbonizing the organic substances like hardwood, coconut shell, fruit stone, saw dust, coal, cellulose residue, walnut, peach pits, babassu nutshell, palm kernel, petroleum coke or anything and everything having high fixed carbon content & potency of activation.

Historically, 1st world war triggered the tremendous use and production of granular activated carbon for adsorbing poisonous gases. The study of activated carbon requires a massive knowledge of pore volume and surface area.

The porosity enhancement requires efficient activation. The activation involves high temperature with/without using inorganic salts with CO2 & steam. The use of chemical activation agent (ZnCl2 or H3PO4) is optional. The resulting AC has a colossal capacity of adsorption from gases and liquids.

To meet the need for diverse industrial, environmental & miscellaneous sources, various AC is commercialized depending on size, shape & application

Granular Activated Carbon (GAC): The mean particle size is approx 1-5mm and is mainly used for water treatment. A high-quality GAC provides durability, high density & effective carbonaceous material. It is effective against organic contaminant in waste water. It can be used for both gases(4×6, 4×8, 4×10 mesh sieve) & liquid (8×20, 20×40,8×30 mesh sieve). It has marked its bulk application in water treatment, deodorization, decolorization, reduce DBP, allied chlorinated solvents, carcinogenic metals (Pb, Hg) & pesticides.

Powdered Activated Carbon: The average particle size is approx 0.1mm and diameter range from 0.15-0.25mm. Being thoroughly crushed, about 95% of the powdered particle will pass through designated mesh sieve. The enormous adsorption is due to a large surface area to volume ratio and small diffusion distance. The applications include raw water in-take, clarifiers, gravity filters, sugar decolorization, Hg & Dioxin removal from flue gas etc.

Pelletised Activated Carbon: The granular form of AC is given a specific shape (cylindrical) by pelletization. It is well known for its high internal porosity, homogeneous activation & diffusion throughout the particle. It has high density, mechanical strength, hardness & low abrasion index. It is profoundly used in air & gas purification.

Silver Impregnated Activated Carbon: In this, the activated carbon (granular/pelletized) is covered with inorganic metals (silver). Being an excellent disinfectant, silver coupled with AC is used as an adsorbent to tackle various water borne diseases, thus can be used for treating domestic water. The eminent bacteriostatic properties with antimicrobial effects hinder the biofilm growth over filter media, thus prolonging the product’s life.
