 Offering advanced Automation,
Fluid Solutions, Dosing
Technology, chemical feed systems, corrosion/scale monitoring
equipment and liquid analysis systems for the water treatment,
chemical, municipal, refining, mineral processing and pulp and
paper industries.
Chemtrack has made great
strides in system automation in Australia offering the
revolutionary LONWORKS technology based controllers for complete
and remote monitoring and control of cooling water and boilers.
Advanced thickener control is
now possible by determining thickener parameters of bed level and
feed solids using the Markland solids/liquid separation
instrument technology and utilising underflow density and rake
torque.
Case History presented at the Coal Preparation Society Meeting at Mudgee Oct 98.
Chemtrack has in association with Nalco Chemical, jointly implemented Markland thickener controls at Charbon Colliery and successfully
trialled the inputs from the Markland 502 SS instrument (High Solids Probe) in the Thickener feed and the Markland 602 Sludge Blanket Level Controller
(Bed Level Probe) as inputs to the Autofloc system to control Flocculant dosage rates and managed to reduce the flocculant consumption by 44%.
This was done based on the model presented as part of the proceedings of the second Australian Coal Preparation Conference, Rockhampton,
1983. A Mathematical Description of Factors Affecting Settling Rates of Slurries, J.R. Macdonald, S.A. Mays, E. Gallaghar and J.E. Lewis.

Complete On-Line Automatic Control of Thickener Circuits
Chemtrack is ready to work
hand in hand with you to determine your specific needs and the
system to meet those needs, then build it to your specifications.
Regardless of the system,
the objective of all Chemtrack process automation systems is
improved plant efficiency, reduced operating costs, and better
manpower utilisation.
Chemtrack has in association with a Power Station and a Global chemical water treatment company, jointly developed
"A Performance-Based Approach to Cooling Water Chemistry Control".
