Anoxic Oxic AO Method Sludge Dewatering Anionic Polyacrylamide
Anionic Polyacrylamide, is solid powder water-soluble polymer with varying molecular weight and charge density. It is most often used to increase the viscosity of water (creating a thicker solution) or to encourage flocculation of particles present in water and allow rapid settlement of finely suspended solids.
It is a synthetic chemical that can be tailored to fit a broad range of applications.
Raitte Chemicals manufactures and supplies specialty water treatment chemicals for oilfield, wastewater treatment, potable water, mineral processing, sugar and paper industries. The range of anionic, cationic and non-ionic flocculants and coagulants are produced in China, our company's headquarters is in Yixing.
In addition to our complete range of powder grade polyacrylamides, marketed under the trade name, our company also supplies polydadmacs (in both powder and liquid form) and polyamine liquid coagulants to cater for all requirements of the industries that we serve. Liquid dispersion polymers will be manufactured in Yixing.

How To Use The Polyacrylamide?
Application and Dosage:
The dosage range of varies from 0.2 - 3.0 ppm depending upon the type of effluent and application. Advised to do jar tests for evaluating the functioning and approximate dosage.
Put sample of effluent in a beaker and add it as designated, agitate for 1 minute at 100-120 rpm and then slowly agitate at 60rpm. Determine the floc properly at this time and note the sedimentation and clarity of top solution.
Procedure and precautions upon dispersion and dissolving flocculants:
Dissolving time: The time required to dissolve the flocculant varies according to the type of flocculant, water quality, temperature and agitation. However, most flocculants generally require around 1 hour of agitation to completely dissolve the powder. Incomplete mixture of flocculant or lumping may inhibit the performance of the flocculant.
Agitation speed: The ideal revolution of the agitator is between 200-400rpm. A high speed agitator operating without reducing the revolution of a motor is not advised, since it may cut the molecules of the flocculant. An ideal agitator motor should be of 1HP for a 1-2m3 mixing tank.
Dissolving concentration: Flocculants should be standardly be dissolved to 0.1-0.5% concentration. It is also effective to start dissolving at a slightly higher concentration, and then dilute the flocculant mixture immediately before use.
Handling measures and precautions:
Proper human safety products such as Splash goggles, lab coat, vapor respirator, gloves and boots should be worn while handling and applying chemicals. Splashes on skin should be washed off with water immediately. In case of splashing into the eyes, flush it with fresh water and obtain medical attention. Should not be injected. Please refer MSDS for more details.
