Solid Anionic Flocculant

Description

The ECOPOL AS series is polyacrylamide based solid 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 AS 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 or flocs which settle faster.

•          Dosage

This kind of product is presented in powder form and is applied in aqueous solution, its optimal concentration of 0.1%. 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 AS series includes a group of anionic 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 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. The high degree of active material minimizes the cost per m³ of treated water.
