Introduction

FLOPAM EM140, EM240, EM440, and EM540 are members of the FLOPAM emulsion polyacrylamide product family, widely used in water treatment, sludge dewatering, mining, industrial wastewater treatment, paper manufacturing, and various solid-liquid separation processes. These products are designed to provide excellent flocculation performance through a combination of charge neutralization and polymer bridging mechanisms.

Although the specific ionic charge density and molecular characteristics may vary among EM140, EM240, EM440, and EM540, all four products are commonly selected for applications requiring rapid particle aggregation, improved settling, enhanced filtration, and efficient sludge dewatering. Their emulsion form allows rapid dissolution, simplified preparation, and reliable dosing in large-scale industrial systems.

The primary purpose of these polymers is to improve the separation of suspended solids from water, increase water recovery, reduce sludge volume, and improve overall process efficiency.

Municipal Wastewater Treatment

One of the most important applications of FLOPAM EM140, EM240, EM440, and EM540 is municipal wastewater treatment.

Municipal wastewater contains suspended solids, organic matter, microorganisms, and colloidal particles that must be removed before treated water can be discharged or reused.
