Due to their large molecular structure, polymers are widely used in various industries, including water and wastewater treatment. Most of the polymers are in powder form and must be prepared in solution form for preparation and combination in various processes. One of the most used types of polymers in the water and wastewater treatment industry is polyelectrolyte. These polymers in the fluid cause suspended particles to join together and clump together. Clumping of suspended particles will increase its density and will eventually cause suspended particles to settle. For this reason, this device is also called polyelectrolyte preparation and injection package.
