 Other Information  
PASP(sodium salt) is an effective chelate reagent and a water-solubility polymer, which has the functions of chelate multivalent metallic cationic. It is a biodegradation environment protection product with peptide linkage and carboxylic acid group without phosphor in molecule, which is green water treatment powder. It acts as a hinder erode powder for cooling water disposal, used water disposal of reverse osmosis and oil field, etc.  It is used to treat with water not only of low alkalinity and low rigidity but of high alkalinity, high rigidity, high temperature and high PH. Hinder dirty capability is not effected by Ph indicator of nitrogen and phosphor.  In the same condition it is better than hinder dirty powder HEDP and ATMP used extensively today.
In agriculture it acts as intensifier for absorbing nutrient, which can improve affection used with pesticide.  Farmland used PASP increases production to 15%-70%, and the crop’s quality improves clearly.
