Improve Water Clarity with Coagulation and Flocculation
Effective water treatment starts with pre-treatment processes—critical for councils and industrial facilities needing to remove suspended particles, organic matter, and contaminants. By introducing coagulants and facilitating floc formation, FILTEC’s water coagulation and flocculation solutions improve treatment for drinking water, wastewater, and industrial process water. Our systems enhance filtration, reduce turbidity, and help facilities meet water quality standards.
Our Pre-Treatment Solutions
Water Coagulation Systems
Coagulation is the first step in the combined aggregation-flocculation process. FILTEC’s water coagulation systems effectively destabilise suspended particles by introducing coagulants that promote aggregation. These systems improve sedimentation, reduce filtration load, and enhance overall water and wastewater treatment efficiency.Â
Water Flocculation Systems
Our water flocculation systems gently mix post-coagulated water to promote floc formation, helping particles bind for efficient solids removal. Designed for effective pre-treatment, FILTEC’s systems support better settling, enhanced filtration, and consistent downstream performance.
How Coagulation and Flocculation WorkÂ
Coagulation and flocculation work together to remove suspended solids and other contaminants from water. Coagulation destabilises particles by neutralising their charge, causing them to aggregate. Flocculation then gently stirs the water, allowing these particles to form larger, more easily removable flocs. This process enhances sedimentation and filtration, ensuring cleaner water for various applications.Â
FAQs
What is the purpose of coagulation and flocculation in water treatment?
These processes remove suspended particles, organic matter, and contaminants, improving water clarity and enhancing downstream filtration and disinfection.
What types of coagulants are used in water treatment?
Common coagulants include aluminium- and iron-based compounds such as aluminium sulfate (alum), Aluminium Chlorohydrate (ACH), ferric chloride, and polyaluminium chloride (PACL). FILTEC supplies systems designed for various coagulant options.
How do I determine the right solids separation system for my facility?
The selection depends on water characteristics, treatment goals, and process requirements. FILTEC can provide expert analysis, after obtaining a representative water sample, and advise on a tailored solution to optimise your treatment process.
Can pre-treatment processes reduce disinfection by-products in water treatment?
Yes, coagulation and flocculation remove natural organic compounds, reducing disinfection byproduct formation and minimising harmful compounds like trihalomethanes (THMs) and haloacetic acids (HAAs).
What maintenance is required for pre-treatment systems?
Regular monitoring, coagulant dosage adjustments, and periodic system checks ensure consistent performance. FILTEC offers servicing and optimisation support to maintain long-term efficiency.
