You can add some water purification agent, the water will become very clear and blue. Purifying agent: Purifying agent is put into the water can react with other impurities in the water. Mainly to play the purpose of water purification. Commonly used purifying agent are polyaluminum chloride, polyaluminum chloride, basic aluminum chloride, polyacrylamide, ferrous sulfate, aluminum sulfate, iron sulfate polymerization. Uses: used in metallurgical, power, leather, pharmaceutical, printing and dyeing, papermaking, chemical and other wastewater treatment industry, the coagulation effect of floc formation (also known as alum) fast and large particles and heavy, rapid settlement. Suitable PH value range of 5 to 9, with less dosage, low cost, high activity, easy operation, wide adaptability, low corrosiveness and so on.
