Sludge Applications
The kajaaniTS solids analyzer (Density) has a proven track record in many Waste Water Treatment plants throughout the world.  Locally, we have installations in Kingston (Ravensview), Durham (Duffin Creek) and City of London (Greenaway).  In each installation, the kajaaniTS has proven its worth through accurate correlations to the laboratory (accuracy) as well as allowing operations to optimize their process.  For example, when measuring the sludge from the primary clarifiers; the above WWTP’s can now change their pumping cycles from time based (fixed period of time) to a more productive cycle based on pumping until a low target (2%) is reached.  In this strategy, the downstream subsystems (Digester and/or Dewatering stages) are not being hydraulically overloaded hence the WWTP’s can now increase their pumping yields.  In upset conditions (rain storms); this latter strategy of pumping until a low set-point is reached ensures that the clarifiers are not building up with solids being swept in and possibly damaging equipment or causing downtime due to maintenance issues.

Cake Applications
The kajaaniTS is the only instrument that is field proven to measure the cake solids that feed the Incinerator.  In our many installations, we have proven that the kajaaniTS correlates to the laboratory such that we can present to the operators both accurate % solids and conductivity readings.  These readings can be used to optimize the operation of the Incinerator.  Fuel savings are a paramount benefit when using the kajaaniTS in the cake feed line to the incinerator.

  
   General
 Microwave technology has been used commonly
    in pulp and paper industry for over 10 years.
 Technology is widely accepted as the most accurate     consistency measurement (Total Solids content).

   Benefits of kajaaniTS:
 Accuracy compared to other technologies
  Does not require licenses (gamma)
 Insensitive to:
   - Product changes (raw material quality, flow rate)
   - Particle size distribution
   - Scaling
 Practically maintenance free

   Savings with kajaaniTS
 Direct savings on:
   - Heating costs
   - Pumping Costs
 Capacity increase on digesting
   - New capacity can be taken to process
 Process benefits
    - Longer delay time on digesting
                       --> more gas --> more energy
    - Higher solids content and reduced polymer       consumption on centrifugal
   - Centrifugal running and service costs are lower
   - Higher solids content reduces transportation costs      and other handling costs


  SmartLC    
 



SmartLC (low consistency) an optical consistency transmitter, uses light polarization to measure the centrate from the centrifuge in Waste Water Treatment plants.
Using this form of measurement allows a plant to gauge how well the centrifuge is operating. If the centrate is low, then the centifuge is also performing optimally. However, if the centrate measures high, more polymer is required.
