Actiflo® Pack is a very compact and fully standardized clarifier package plant used for various applications such as drinking water, wastewater treatment, reuse or process water.
Overview
Clarification is a key process step in most water treatment plants used for the production of drinking water, industrial process water, for wastewater treatment and reuse.
Actiflo® Pack is a very compact and fully standardized clarifier package plant based on Actiflo’s high rate, compact, microsand ballasted clarification patented process by Veolia Water Technologies.
How does Actiflo® Pack work?
Actiflo Pack uses microsand which enhances the formation of robust flocs and acts as ballast, significantly increasing their settling velocities. The unique characteristics of the resulting microsand ballasted flocs allow for clarifier designs with very short hydraulic residence times, high rise rates and extremely compact system footprints that are 4 to 8 times smaller than lamella or dissolved air flotation (DAF) clarifiers and up to 50 times smaller than conventional clarification systems of similar capacity.
Features and benefits
The Actiflo Pack ACP2 range now includes eight models with numerous standard options and alternatives to enhance performances and monitoring all water and wastewater sources.

FAQ about Actiflo® Package Plant
What is clarification?
Clarification is a key process step in water treatment. Its main aspects are:
- Coagulation - Chemicals like alum or ferric chloride are added to destabilize suspended particles and allow them to clump together.
- Flocculation - Gentle mixing causes the destabilized particles to agglomerate into larger "flocs".
- Sedimentation - The flocs are allowed to settle out by gravity in clarifier tanks. This removes most of the suspended solids.
The clarification process removes turbidity and suspended solids like clay, silts, natural organic matter, iron and manganese hydroxides, microorganisms, etc. It prepares the water for further treatment steps like filtration and disinfection. Key process parameters are coagulant dosing, flocculation time and mixing intensity, clarifier design and solids removal efficiency. Optimization of clarification is critical for downstream process performance.
What is the role of a polymer during a clarification process?
During the clarification process, a polymer plays a crucial role in the coagulation and flocculation stages. The polymer is used as a flocculating agent to facilitate the aggregation of fine particles in the water. Once the polymer is added, it helps to neutralize the charges of the small suspended particles, allowing them to stick together and form larger aggregates known as flocs. This process is known as flocculation. The larger flocs are then more easily removed from the water during the sedimentation stage of the clarification process.
What are the advantages of a package plant?
Package plants have several advantages. They are fabricated in Carbon Steel or Stainless Steel. The wide range of standard units allows them to be suitable for very small treatment capacities to medium and large treatment capacities. The use of package plants leads to reduced overall project schedule and costs, provides faster installation, lower startup risks, predictable operation and consistent quality for water treatment.
