CIF® for Process Water Treatment

Continuous Ionic Filtration (CIF®) from Multotec can achieve water recoveries of up to 95% and higher in various applications like mining, industrial and municipal process water treatment. It is also proven highly effective for metals recovery, including base metals recovery.

The CIF® water treatment process simultaneously removes dissolved salts (TDS) and suspended solids (TSS) from process water.

Multotec partnered with Australian company Clean TeQ to introduce continuous counter-current ion exchange technology to the African market. The process water treatment technology is now available worldwide from Multotec – helping global companies reduce operating and capital costs.

  • High water recovery
  • Reduced brine production
  • Reduced chemical consumption
  • Reduced maintenance requirements
  • Smaller plant footprint

Features and operation of CIF® 

CIF® has high solids handling capabilities and is flexible to changing feed conditions. It has the potential to recover valuable by-products and is able to achieve zero liquid discharge (ZLD). A few additional features include:

  • Modular and mobile
  • Self-cleaning
  • Robust, with the ability to operate in high scaling and fouling conditions
  • Optimised resin inventory

The way it works

  • Adsorption: Feed water enters the bottom of the adsorption column and leaves via the top, ready for beneficial re-use or complementary processing.
  • Resin washing: “Dirty” ion-loaded resin is washed from contaminant solids in a fluidised wash process.
  • Desorption: Ion-loaded resin is introduced to the application-specific regeneration solutions, alkalis, acids or salts.
  • Final Washing: Regeneration solutions are washed from the regenerated resin for recovery and reuse in the Ionic Filtration column.

Process Water Treatment

Filter, separate and purify process water with lower costs and maintenance. The modular full-scale and mobile CIF® range for process water treatment consists of single stage CIF®, dual stage DeSALx® and HiROx® to remove both cations and anions from feed waters.

  • Scaling ions (Ca, Mg, Ba, Sr, Mn, Fe,  carbonate  etc), fouling species, heavy metals
Benefits:
 

 

  • Suitable for a range of water qualities and  applications
  • Simple solution for agricultural water production

Dual Stage CIF® (DeSALx®) for desalination of water under high fouling and scaling conditions, whilst achieving high water recovery. 

Applications: 
  • Desalination of Brackish Water TDS < 5000 mg/L
Elements Removed:
  • Dissolved salts
Benefits:
 

 

  • Lower cost and power consumption when compared to RO
  • Minimal to no pre-treatment required
  • Production of potentially valuable by-products
  • Crystallisation add-on to produce a solid salt by-product

High Recovery Reverse Osmosis (HiROx®) combination of CIF® with reverse osmosis achieves zero liquid discharge. 

Applications: 
  • Desalination of Brackish Water TDS < 5000 mg/L
Elements Removed:
  • Dissolved salts
Benefits:
 

 

  • Lower cost and power consumption when compared to RO
  • Minimal to no pre-treatment required
  • Production of potentially valuable by-products
  • Crystallisation add-on to produce a solid salt by-product

Achieving Zero Liquid Discharge with Multotec products and services 

In mining and industrial process water treatment, water should be considered a revenue stream instead of something to treat and dispose. These wastewaters from many mines contain valuables and some mines are currently relooking at ways of using recycled water to produce revenue. 

The Continuous Ionic Filtration® (CIF®) technology developed by Clean TeQ and used by Multotec in its process water treatment and solid liquid separation applications is, in fact, metal recovery technology. 

This technology has evolved to become a dual-purpose treatment as it is often used purely as a water treatment solution. Technologies like this help companies achieve zero liquid discharge (ZLD), among other treatment processes, in mine water treatment among others.

Multotec has invested in a 1 m³/h two-stage test rig which is available for piloting the CIF® technology.

International mining houses such as Glencore Xstrata, Anglo Coal, BHP Billiton and Rio Tinto use Multotec equipment to reduce running costs and optimise plant performance.
