Fine suspended solids in the juice will not settle on their own and cloud the clarified stream. Flocculants, sold as SVI FLOC, gather those solids so they settle and leave a clear juice for the clarifier.
This guide explains what the flocculants do, where they fit, and how they are dosed.
What Flocculants Does
Flocculants are high molecular weight anionic products in an active powder form used for clarification.
They come in grades, SVI FLOC 724 for sugar syrup clarification, SVI FLOC 725 for filtrate clarification, and SVI FLOC 985 for syrup and juice clarification.
By gathering fine solids into settling flocs, they accelerate settling and produce a mud cake of good density for clarification.
Where It Fits in the Plant
Flocculants fit at the clarification and filtration stations, where suspended solids must be settled out.
They are used in clarifiers, thickeners, vacuum filters and lime softeners, and also benefit filtrate juices and cane syrup.
Wherever fine solids must be settled from the stream, the right grade of flocculant is dosed.

What Makes It Effective
The product is judged by how well it does its job in the process.
Fast Settling of Solids
The flocculant must gather fine solids so they settle. It accelerates the settling of suspended colloidal impurities and produces a mud cake of good density, which is what makes for good clarification.
Works at Low Dosage
Because it often works at very low dosages, a little flocculant clarifies a large flow, which keeps it effective and economical.
How It Is Used
Flocculants are dosed into the stream ahead of the clarifier, thickener, vacuum filter or lime softener.
Dosed there, they gather the fine solids into flocs that settle and leave a clear stream.
Because they work at low dosage, only a small amount is needed for a large flow.
Common Questions About Flocculants
They gather fine suspended solids into settling flocs, accelerating settling and producing a mud cake of good density for clarification.
They are used in clarifiers, thickeners, vacuum filters and lime softeners, and also benefit filtrate juices and cane syrup.
Yes, SVI FLOC 724 is for sugar syrup clarification, 725 for filtrate clarification, and 985 for syrup and juice clarification.
They are high molecular weight and often work at very low dosages, so only a small amount clarifies a large flow.
Get a Clear Clarified Stream
Flocculants gather fine solids so they settle fast, giving good clarification in clarifiers, thickeners, vacuum filters and lime softeners.
