Water is used in all sorts of production processes as a utility. During processing, the water becomes contaminated, and considered as wastewater that is hard to define. However, it needs to be either recycled or discharged according to the local regulations. Wastewater can be treated on-site prior to reuse or discharged to the sewerage system.
The Jacobi Services mobile filters from the AquaFlow™ range filled with different media are used to treat industrial wastewater. Contaminants that can be found in industrial wastewater can include:
- Organic contaminants, in most cases expressed as sum parameter such as
- AOX (Adsorbable organic halogenated compounds)
- COD (Chemical oxygen demand)
- TOC (Total organic carbon)
- Specific organic contaminants
- Aromatic hydrocarbons, including BTEX: benzene, ethylbenzene toluene, and xylene
- Halogenated hydrocarbons
- Organo metallics (containing tin or mercury, for example) compounds coming from chemical synthesis processes
- Pesticides and herbicides
- Inorganic contaminants
- Heavy metals
The increasing strength of legislation related to the discharged wastewater quality urges the implementation of new, efficient, and cost-effective purification solutions. Depending on the discharge limits, water needs to meet specifications relating to COD, TOC, AOX, pesticides, and heavy metals amongst others.
INDUSTRIAL WASTEWATER: MOBILE FILTERS
AquaFlow™
The AquaFlow™ range of mobile water treatment adsorbers have been successfully used for industrial wastewater treatment. The filters are selected based on the annual carbon consumption and flowrate. The mobile adsorbers can be operated in a combination of parallel and/or series connection.
INDUSTRIAL WASTEWATER: SOLUTIONS
Auxiliary equipment and additional services
In addition to mobile filters and different media, Jacobi Services also offers auxiliary equipment and additional services, such as:
Isotherm testing with the user to estimate the annual activated carbon consumption.
Media sample pots that are run in parallel with the AquaFlow™ mobile filter. These accelerate the availability of saturated media, such as activated carbon and ion exchange resins, to determine the suitability for reactivation or disposal route of the spent material.
Application specialists within the international Jacobi service team can provide start-up assistance.
Recycling, Energy Recovery or Disposal Services
The Jacobi adsorbents are used in a wide range of applications. Adsorbents generally have a limited lifetime and need to be replaced once they are saturated or the treatment objective is reached. Jacobi Services offers several recycling, energy recovery or disposal services in different facilities, depending on the properties of the spent material.
INDUSTRIAL WASTEWATER: PRODUCTS
AquaSorb™ 100 Series
The AquaSorb™ 100 series are designed for water treatment, for example, in soil remediation and wastewater projects. This range of products has been used to remove polyaromatic hydrocarbons, chlorinated solvent and mineral oils from water in soil remediation projects.
AquaSorb™ ASR-1
AquaSorb™ ASR-1 is an efficient media to remove arsenic compounds from landfill leachate. The arsenic removal efficiency of AquaSorb™ ASR-1 mainly depends on the pH and redox potential of the water and competitive adsorption of other impurities.
ReSorb™
The ReSorb™ range of reactivated pool carbons are used to remove organics from landfill leachate.
INDUSTRIAL WASTEWATER: ION EXCHANGE RESINS
Resinex™ Chelating Resins
The Resinex™ chelating resins can be used to remove heavy metals from Industrial wastewater. These chelating resins are used to remove heavy metals and work on the principle of complexation. The functional group of the resin is a ligand which forms complexes with the heavy metals cation to be removed from the solution (transition metals). Resinex™ chelating resins can remove the heavy metals with cations in water down to ppt level. The choice of the chelating resins depends on the type of heavy metal, type of functional group of the resin, other heavy metals in the water matrix and operating parameters of the system.
Resinex™ AP
Resinex™ strong base anions, such as Resinex™ A-4 or Resinex™ AP, can be efficiently used to remove chromates from water, reducing to 10 ppb, with two columns in a serial, merry-go-round system. Due to their large loading capacity (up to 30g Cr/L resin), resins are intended for single use. Besides chromates, other toxic oxyanions, such as molybdate and vanadate, can be effectively removed by Resinex™ strong base anions.
Resinex™ TPS-2300 SO4
Resinex TPS-2300 SO4 is a macroporous strong base anion specially designed for uranyl complexes removal in water. The resin being loaded with sulfate, the most attracted anion, the treated water composition will not be changed, except the removal of uranium and other oxyanions. Resinex TPS-2300 SO4 is exclusively for single use.
Resinex™ A4
Cyanides in water can be found either as free cyanides (CN-/HCN) or as metal cyanides anionic complexes (eg. Zn(CN)42-, Fe(CN)64-). Resinex™ A-4 is a strong base anion which can adsorb metal cyanide complexes. Resinex™ A-4 exhibits a very high affinity for metal cyanide complexes. This means complexes cannot be eluted and the resin is intended for single use.
Resinex™ PR1
Resinex™ PR-1 is a strongly basic macroporous-type anion exchange resin, specially developed for selective perchlorate removal from water in presence of high levels of sulphate. With an inlet concentration of 50 µg/L of perchlorate, the typical Resinex™ PR-1 loading capacity is ± 5 g ClO4-/L resin. With two columns in series, working as a lead-lag system, the outlet concentration is under the detection limit, usually reported at 0.2 µg/L. Resinex™ PR-1 is also suitable for nitrate removal applications. This resin is recommended for single usage.
Resinex™ PFCR-2
Resinex™ PFCR-2 is a special gel type strong base anion resin dedicated to removing perfluoroalkyl substances, even in presence of high levels of sulfate. Resinex™ PFCR-2 is particularly efficient when it comes to eliminating perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). In combination with activated carbon, the resin acts as a polisher by primarily removing short chain perfluorinated compounds, whilst activated carbon fixes longer chain compounds.
