Solid Cationic Flocculant

Description

The ECOPOL CS series is polyacrylamide based solid polymers with high molecular weight and different charge densities. These cationic polyelectrolytes act as floc formation accelerators, generally in flotation systems, and as water-sludge separation agents, also improving sludge dewatering processes in centrifuges and band filters. 

Application

•          Selection

These solid cationic polyelectrolytes are commonly used for two different applications. On the one hand, are used in physical and chemical processes of wastewater treatment as accelerants of floc formation, generally in flotation systems. On the other hand, are used to improve the separation processes of sludge dewatering systems, such as band filters or centrifuges.

•          Dosage

This kind of product is presented in powder form and is applied in aqueous solution (0.1%). For this preparation, the solid product is slowly added over the stirred water, manually or automatically. After a maturation period, the mixture is ready to be dosed by pump.

•          Control

Generally, control of flocculating product efficiency is directly related to the rate of floc formation and its aspect. After dosing, the size of the floc must change rapidly, rising steadily to a maximum value. Moreover, the separation of water is more evident, being very visible after collecting a sample dosed with all products.

Benefits

•          Technical

The ECOPOL CS series includes a group of cationic high molecular weight polymers and different charge densities. A wide range of wastewaters from specific industries are able to be treated, offering a customized solution in almost every case. The high polyelectrolyte molecular weight favours crosslinking processes of suspended solids through the polymer chain. Meanwhile, different charge densities allow selecting the optimal treatment that effectively neutralizes the counterion present in the wastewater.

•          Economic

The ECOPOL CS series presents a wide range of flocculants products with different intrinsic physicochemical properties capable of providing the appropriate treatment in each case and thus, reducing the resources needed for proper treatment or reuse of wastewater. This has a direct impact on decreasing treatment cost, increasing the lifetime of the facilities, the elimination of human resources and limiting generated wastes. The high degree of active material minimizes the cost per m³ of treated water.
