Why do you need Clearflow Gel Flocculant?

Gel Flocculant blocks offer cost effective water clarification treatment by quickly removing total suspended particles, metals, and phosphorus. These ready-to-use blocks eliminate the need for expensive traditional systems and are ideal for wastewater treatment, stormwater clarification, sediment control, and industrial water treatment solutions. Manufactured in the USA and Canada, they utilize flow energy and particle dynamics to release the flocculant efficiently. Enhance your water treatment processes with Clearflow Gel Flocculant blocks for superior turbidity reduction, phosphorus reduction, and heavy metals removal. Find flocculant products near you for reliable and sustainable water treatment.

Types

What are the different types of Gel Flocculant?

Patented Technology

300 Series

Anionic

The 300 Series Gel Flocculant blocks are negatively charged and play a crucial role in water treatment by causing particles to form large floccules that are more easily separated from the water.

Patented Technology

400 Series

The 400 Series Gel Flocculant blocks are used to pretreat suspended solids making them easier to bind together with 300 Series blocks. Gel Flocculants are effective in removing heavy metals and nutrients such as phosphorus from the water.

Patented Technology

600 Series

Cationic

The 600 Series Gel Flocculant blocks are positively charged and are used in water treatment and wastewater purification to flocculate suspended solids that are organic in origin.

Patented Technology

Cationic Neutralizer 369

Cationic Neutralizer

The Cationic Neutralizer block is a negatively charged flocculant product that releases faster than the standard 300 Series. It is used to neutralize the positive charge of 600 Series Gel Flocculants or other cationic flocculants and coagulants.

Specific characteristics of Clearflow Gel Flocculant

Clearflow's Gel Flocculant is used in water treatment to efficiently remove suspended particles, reduce TSS, and eliminate metals and phosphorus, ensuring effective water clarification for dewatering operations, and in lakes, ponds, and streams.

Passive in-situ treatment
Easily stored
Environmentally safe
Self-dosing - self-limiting
Eliminates makedown and dosing equipment
Reduces TSS/NTUs, metals, phosphorus
Neutralizes cationic coagulants and flocculants
High operating pH range (3–12); works alongside on-the-fly pH adjustment
High salinity tolerance — fresh water and ocean water
Wide temperature range — freezing to boiling (requires moving water)
