I. Using methods and attentions

Because of different nature of the raw water, on-site adjustment or beaker experiment should be conducted based on different situations in order to achieve optimal use conditions and most appropriate dosage to realize the best treatment effect.

 

  1. Before use, put this product at a certain concentration (10-30%) into the alum-solution tank, and then input clean water to facilitate the full hydrolysis. Keep it still until it becomes reddish brown, and then add clean water to dilute it to the required concentration for releasing and coagulation. The water plant can prepare it at a concentration of 2-5% for direct release; while for industrial wastewater treatment, it can be prepared at 5-10% for direct release.
  2. The dosage of releasing shall be determined according to the formation of alum floc through production debugging or beaker experiment based on the nature of raw water. The dosage used by water plants can be determined by reference to that of other agents. Under the same conditions, this product and solid PAC shall be used less, about 1/3-1/4 dosage of solid aluminum sulfate. If liquid product is used, the dosage shall be determined through calculating the concentration of appropriate drugs. 
  3. Pump the above prepared drug liquid into a measuring tank and release it after measurement for coagulating the raw water.
  4. Under normal circumstances, the product should be used out on the date of preparation. Tap water is needed in preparation. Otherwise, it is normal to see little sediment.
  5. Please pay attentions to the hydrodynamic condition and formation of alum flocs in the three phases of the coagulation process.

(1) Condensation phase: it is a process to input prepared agent into the raw water for rapid coagulation and form small alum flocs in short time. In this course, the water will become more turbid, which requires the water to produce intense turbulence. In the beaker experiment, stirring should be quickly conducted (250-300 r / min) for 10-30S, but shall not exceed 2 min in general.

(2) Flocculation phase: It is a process for alum flocs to grow thicker. This course requires appropriate turbulence and sufficient residence time (10-15 minutes). At the later stage, we can see that a large number of alum flocs gather together and slowly sink and form a clear surface layer. In the beaker experiment, stirring should be quickly conducted at a speed of 150 r/min for about 6 minutes and then at 60 r/min for 4 minutes or so.

(3) Sedimentation phase: It is a sedimentation process of flocculates carried out in the sedimentation tank. This course requires slow water flow. In order to improve the efficiency, an inclined tube (plate) sedimentation tank (preferably use flotation method to separate flocs) is adopted generally to hold up a large number of thick alum flocs and settle at the bottom. Now, the upper water becomes clear and the remaining small alum flocs at low density will drop down slowly and continue to combine with each other through collision. At the later stage, the turbidity will keep basically unchanged. In the beaker experiment, it is appropriate to stir the liquid at a speed of 20-30 r/min for 5 minutes, keep it still for 10 minutes and measure the turbidity. 

 

6. For enhanced filtration, it is necessary to adopt reasonable filter layer structure and filter aid in order to enhance the removal rate of filter tank. It is an important measure to improve the water quality.

7.This product is applicable to environmental protection and treatment of industrial wastewater. When it is used for industrial wastewater, its using methods are basically same with in water plants. For the treatment of raw water with high chroma, high COD and BOD, very good effect will be obtained by combining aid agent.

8.For factories and mines adopting chemical coagulation, it is unnecessary to transform their original equipment, but needs to set up an alum-solution tank.  

9.The product should be stored in dry place and should be protected from moisture and heat (<80°C). Don’t damage its package. The product can be stored for a long term.

10. This product can be used only after dissolution. But the dissolution equipment and releasing equipment should be made of corrosion-resistant materials.
