RXSOL ANIONIC POLYMER FLOCCULANT should be fed via a closed feed system. A closed feed system is defined as a system in which fluid is moved from a closed storage vessel into a treated media without exposure to the atmosphere (except through normal venting or pressure devices).
Emulsion flocculants must be fed following proper makeup procedures. Suitable inversion systems  should  be utilized to allow for adequate inversion and feeding control. The quality of water used to invert the polymer is important. Avoid using plant recycle water or other water sources high in suspended solids, mineral salts and iron, and with a pH either below 6.5 or above 7.8.
A dilution aging tank is highly recommended, with a minimum of 30 minutes aging in order to gain full product activity. Inverting the emulsion flocculant below a concentration of 0.2%, or above a concentration of 1.0%, is not recommended. A positive displacement pump is recommended for feeding the inverted material to the treatment system. In some cases, continuous dilution of pre-inverted flocculant will enhance activity and generate more cost-effective results. Improved performance using dilution water is site specific. To determine if post-dilution is advantageous, feed inverted product through a standard mixing tee to an active dilution water line. The water temperature should be close to ambient and low on suspended solids, mineral salts and iron.

In most cases, inverted flocculant should be fed on the discharge side of the feed pump. There may be isolated cases where the additional mixing rendered by distributing the polymer on the suction side of the pump will yield better program
