How Bluwat Helps Customers Choose the Right Water Treatment Chemicals
The most suitable chemical depends on the wastewater composition, treatment objectives, operating conditions, and desired water quality.
The Right Chemical Is Not Always the One That Settles Fastest
Choosing the right water treatment chemical requires more than comparing product specifications or selecting the flocculant that produces the fastest settling.
The most suitable chemical depends on the wastewater composition, treatment objectives, operating conditions, and desired water quality.
At Bluwat Chemicals, laboratory jar testing is an important part of evaluating potential treatment solutions.
Our approach focuses on three questions:
What are the main characteristics of the wastewater?
What does the customer need to achieve?
Which chemical or treatment combination can meet those requirements most effectively?
By comparing chemical performance under controlled laboratory conditions, Bluwat helps customers identify promising treatment options before larger-scale trials.
A recent comparison involving PolyDADMAC and Polyacrylamide (PAM) for metal mine tailings wastewater illustrates this approach.

01
A Simple Experiment That Demonstrates Why Chemical Selection Matters
In a laboratory test, two different polymer-based water treatment chemicals were evaluated using metal mine tailings wastewater.
PolyDADMAC was added to one sample, while PAM was added to the other.
After chemical addition and mixing, floc formation was observed, followed by sedimentation.
What Did the Experiment Show?
The two chemicals produced different treatment results.
PAM Treatment
Faster sedimentation of flocculated solids
Rapid formation of a visible settled layer
Relatively turbid supernatant
PolyDADMAC Treatment
Slightly slower sedimentation
Clearer supernatant after settling
Improved visual clarification under the tested conditions
Both chemicals contributed to particle separation, but their observed advantages were different.
Which Chemical Was Better?
The answer depends on the treatment objective.
For a tailings thickening operation where rapid settling is particularly important, the PAM result may be more relevant.
For an application prioritizing supernatant clarity, the PolyDADMAC result may deserve further evaluation.
If both rapid settling and low residual turbidity are required, additional tests may be necessary to identify a more suitable polymer grade, dosage, or treatment combination.
This is why Bluwat emphasizes application-based chemical selection rather than recommending the same product for every wastewater treatment system.
Technical Note: These findings describe only the specific laboratory comparison. Polymer performance varies with product grade, dosage, wastewater properties, and operating conditions.
02
How Does Bluwat Select Suitable Water Treatment Chemicals?
Chemical selection begins with understanding the customer's wastewater and actual operating requirements.
01
Understand the Wastewater Characteristics
Different industries generate wastewater with different compositions.
Before recommending a product, relevant information may include:
Wastewater source and industrial application
pH and operating temperature
Suspended solids and turbidity
Color and organic contaminants
Oil and grease content
Dissolved or suspended metals
Existing treatment chemicals and processes
Required final water quality
For example, wastewater from a mineral processing plant may contain fine inorganic particles, while textile wastewater may contain dyes and other dissolved organic compounds.
The appropriate treatment approach can therefore differ substantially.
02
Define the Customer's Treatment Objective
Wastewater treatment is not always about achieving the clearest possible water.
Customers may need to prioritize different results.
Common treatment objectives include:
Rapid sedimentation
Turbidity reduction
Color removal
Sludge dewatering
Oil-water separation
Heavy metal removal
Improved process water recycling
Lower chemical consumption
More stable treatment performance
Understanding these priorities helps determine which performance indicators should be evaluated during laboratory testing.
For example, the preferred chemical for a tailings thickener may differ from the preferred chemical for final effluent clarification.
03
Screen Potential Coagulants and Flocculants
Based on the wastewater characteristics and treatment objectives, different chemical products can be considered.
Bluwat's product portfolio includes several major categories.
These products perform different functions and are not interchangeable in every application.
For example, PAM may be used as a flocculant to promote particle aggregation, while PAC or PolyDADMAC may be evaluated for coagulation.
Where both coagulation and flocculation are required, a combined treatment process may be considered.
04
Conduct Laboratory Jar Tests
Jar testing provides a practical method for comparing chemical performance using actual wastewater samples.
During laboratory evaluation, different products or dosages can be tested under controlled conditions.
The evaluation may include:
Chemical Addition
Selected chemicals are added to the wastewater at controlled dosages.
Mixing and Floc Formation
The samples are mixed to distribute the chemicals and encourage interactions with suspended particles.
Sedimentation
Mixing is reduced or stopped, and the settling behavior of the formed flocs is observed.
Performance Comparison
The treated samples are compared based on relevant criteria, including settling speed, supernatant clarity, floc characteristics, and chemical consumption.
The mining wastewater experiment demonstrates why comparing more than one performance parameter is important.
A chemical providing rapid settling may not always produce the lowest residual turbidity.
05
Optimize the Treatment Conditions
After identifying promising products, further tests may be required.
Optimization can involve adjustments to:
Chemical dosage
Polymer type and molecular weight
Charge density
Wastewater pH
Chemical addition sequence
Mixing conditions
Flocculation time
The objective is to identify a treatment approach that achieves the customer's required performance without unnecessary chemical consumption.
Actual results must be verified using the customer's wastewater and operating conditions.
06
Evaluate Practical Application Requirements
Laboratory performance is only one part of chemical selection.
Before full-scale implementation, customers must also consider operational factors.
These may include:
Compatibility with existing treatment equipment
Chemical preparation and dosing requirements
Sludge production and handling
Treatment consistency
Overall operating cost
Final discharge or reuse requirements
Where necessary, additional pilot or plant-scale trials can help confirm whether laboratory findings translate to real operating conditions.
03

04
Why Different Industries Need Different Chemical Solutions
The mining wastewater experiment highlights a principle that also applies to other industries:
The same chemical does not necessarily deliver the same performance in different wastewater systems.
For example:
A mining operation may prioritize settling speed and process water recovery.
A textile factory may prioritize color removal and clarification.
A paper mill may focus on fiber separation or sludge treatment.
A municipal wastewater plant may need efficient sludge dewatering.
An oilfield operation may need emulsion breaking followed by solids separation.
An electroplating facility may require dissolved metal removal before final clarification.
Because these objectives differ, the ideal chemical, dosage, and application procedure may also differ.
This is why laboratory evaluation is an important starting point for treatment optimization.
