Retention and drainage programs can improve the overall performance of a paper machine but they can also negatively impact formation.  The fact is that retention, drainage, and formation must be precisely balanced to achieve the desired sheet quality at an effective production cost.  Hercules' retention, drainage, and clarification programs are designed to help you achieve and maintain this critical balance.  Our broad product offering and global expertise with such programs allows us to prescribe a total system approach tailored to meet your needs.
