The use of GRAMICID-PHB replaces soda ash and lime in water treatment. It has many advantages from the standpoint of pH control and softening.
The method for chemical treatment of water will vary considerably based on the water analysis and the quality of water desired. In many plants, the use of
GRAMICID-PHB may be the only chemical required to give the desired properties.
pH Adjustment:-
The pH of water using GRAMICID-PHB may be either adjusted before sedimentation and filtration, or after filtration, or both-depending upon the characteristics and the optimum pH of flocculation. Generally pH adjustments need be made only after filtration to prevent the corrosion of the pipelines of the distribution system.
GRAMICID-PHB used for pH adjustment, and each has its special advantages. However, for ease of handling, cleanliness of operation and ease of control, as well as an absence of hardness increase, the feeding of GRAMICID-PHB is best. The amount of these chemicals to raise the pH will vary with the specific water being treated,
