Ion exchange resin analysis
|
|
|
|
|
|
|
|
|
Periodic laboratory testing and analysis of your ion exchange resin is recommended to ensure the optimum performance of your water treatment system.
Ion Exchange resin testing helps determines the quality of your resin and can help to diagnose your water system's operating problems.
Periodic testing of your resin helps to ensure that your system continues to operate optimally and efficiently.
Lenntech can testing your resin with the following sevices;

Deposit and microbiology laboratory analysis
|
|
|
|
|
|
|
|
|
The complete analysis of a deposit is critical in determining the appropriate deposit control program for a machine. On-site evaluations using light microscopy and simple qualitative tests provide preliminary answers to the problem. More detailed information is obtained from semi-quantitative and quantitative laboratory analyses.The resulting data on the deposit combined with system knowledge are essential in choosing and implementing the correct deposit control program.
Deposits that impact a machine efficiency and runnability are categorized as organic, inorganic, or microbiological. Typically, most deposits will be a combination of all of these. Organic deposits generally are classified into four groups: pitch, stickies, papermaking additives, and white pitch. Inorganic deposits include scale, filler, and other inorganic components. Common scales are calcium carbonate (CaCO3), barium sulfate (BaSO4), alumina (Al[OH]3), and calcium oxalate (CaC2O4).

Coagulation / Flocculation testing
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
A wide variety of chemicals exist for use in clearing raw water of suspended solids in coagulation/flocculation processes. It is known that the effectiveness of these coagulants has a complex dependency on the nature of the raw water, being affected by such things as temperature, pH, and especially the specific proportions of organic, inorganic, and biological particles that constitute the suspended solids. Furthermore, it is typically found that combinations of coagulants can be used to achieve much higher performance and process efficiency, but this performance again depends on the complex nature of the water source.
