Industrial Grade Copper Sulfate Pentahydrate differs in color due to its different content. For example, the appearance is powdery, and the color is golden yellow or light yellow and yellow brown. With the changes in the production process and raw materials of Industrial Grade Copper Sulfate Pentahydrate, many customers can truly distinguish the content of polyaluminum chloride with the naked eye.
   Put Industrial Grade Copper Sulfate Pentahydrate in the sun. If it is 30% polyaluminum chloride, it is usually shiny golden or light yellow, and 28% is also shiny but the color is slightly dark and yellow. If it is non-standard around 25, the color will be darker.
   Generally speaking, the content of Industrial Grade Copper Sulfate Pentahydrate within the scope of the national standard is 27-30. It is a yellow or light yellow solid powder, easily soluble in water, and has strong bridging adsorption. In the hydrolysis process, with the physical and chemical changes such as electrochemistry, aggregation, adsorption and precipitation, [Al2(OH)3(OH)3]α↓ is finally formed, thereby purifying the object.
  Industrial Grade Copper Sulfate Pentahydrate does not need to add other additives, the flocs form fast and rough, the activity is high, the precipitation speed is fast, and the purification effect of high turbidity water is obvious. Its pH value has a wide range of adaptability and has no corrosive effect on pipeline equipment.
   Alternatively, the method of distinguishing the quality of different amounts of Industrial Grade Copper Sulfate Pentahydrate products can also be determined by water-insoluble substances. Go to the mineral water bottle and fill it with water. Take an appropriate amount of polyaluminum chloride for the test, put it in a water bottle, shake the lid vigorously until Industrial Grade Copper Sulfate Pentahydrate is completely dissolved. Then let it stand for one hour and observe the amount of insoluble water at the bottom of the bottle. The less the better.
