Coagulation
For destabilising colloids and fine particles.
Discuss suitabilityWastewater
Better separation with less process variation.
Coagulation, flocculation, antifoam and technical support for industrial wastewater streams.
System approach
Treatment tailored to your installation
The right treatment depends on particle charge, pH, residence time, mixing energy and the next step in the separation process.
Signals to investigate
- Fluctuating turbidity or COD load
- Poor floc formation or settling
- High chemical consumption
- Foam or unstable sludge dewatering
Available approaches
Integrated product, equipment and support
Flocculation
Anionic and cationic product families for floc formation and separation.
Discuss suitabilityTrials & optimisation
Selection through practical testing and verification of dosing and mixing.
Discuss suitabilityFrom product to programme
Make selection, dosing and performance verifiable
A treatment programme is complete only when it is clear in advance what is assessed, how it is applied and which measurements will be used to verify performance.
What we assess technically
- Origin and variation of flow, particle load and dissolved components
- pH, alkalinity, charge and response to coagulant or flocculant
- Mixing energy, dosing sequence, residence time and sensitivity to floc break-up
- Downstream step such as settling, flotation, filtration or sludge dewatering
What we monitor during operation
- Turbidity, suspended solids and a relevant organic or chemical load measure
- Settling rate, floc strength, filtrate quality or flotation behaviour
- Sludge dry-solids content and dewatering stability
- Chemical consumption per treated quantity and total sludge production
Frequently asked questions
Technical choices require system context
These answers provide initial direction. The final approach follows from the installation data and product documentation.
Why does product selection often start with a jar test?
A test series shows how water from the actual installation responds to product type, dose, pH and mixing. Variation between samples must also be tested.
What is the difference between a coagulant and a flocculant?
A coagulant destabilises fine or colloidal particles. A flocculant then helps form larger flocs that are easier to separate. Not every process requires both in the same form.
Why does a laboratory dose not always work directly in the plant?
Mixing energy, dosing point, residence time, dilution, process variation and floc shear differ at plant scale. Plant validation is therefore part of the selection process.
