Liquid anionic flocculant

Liquid Anionic Flocculant

Liquid Anionic Flocculant

Description

The ECOPOL AL series is polyacrylamide based liquid polymers with high molecular weight and different charge densities. These anionic polyelectrolytes act as accelerators of sedimentation after previous treatment of coagulation or as clarified agents in static settling.

 

Application

•          Selection

The ECOPOL AL series products are used in sedimentation processes after coagulation pre-treatment, or as clarified agents in a stating settling. Through charge exchange and crosslinking processes of suspended solids in the polymer chain these polymeric compounds are able to increase the size and consistency of the formed flocs, generating agglomerates which faster settle.

•          Dosage

These products are presented in liquid form and are applied in aqueous solution, with optimal concentration of 0.2%. For this preparation, the 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 AL series presents group anionic high molecular weight polymers with different charge densities. A wide range of wastewaters from specific industries are able to be treated, offering a customized solution in almost every case. 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. It is important to note that the pre-dissolution of the product in water improves substantially its efficiency compared to solid flocculants, as the maturation time is less and the preparation is further stabilized, facilitating automation dosing and avoiding problems of maintenance equipment dosage.

•          Economic

The ECOPOL AS series presents a wide range of flocculant 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.
