Note:   All the indexes of the heavy metal and insoluble matter listed in the table   are calculated based on a 41% ferric chloride content

Product   properties

1.   The product has a good effect in removing COD, BOD and total phosphorus of   all types of waste water;

2.   It has good performance in dehydrating sludge and is applicable under a wide   range of raw water temperatures and pH values;

3.   It forms dense alum flocs which precipitate quickly, lessening the phenomena   of alum floc floating and back washing   times of the filtration tank;

4.   The product enables cost reduction in water treatment as an ideal chemical   for sewage treatment.
