Poly aluminum chloride treatment of cold water production wastewater in summer Process Poly aluminum chloride treatment of cold water production wastewater in summer Process Hot summer arrived, with the beginning of cold drinks when the plant is full bloom, with the result is cold drinks factory The increase of production wastewater, some customers reflect how to effectively deal with the production of cold drinks plant wastewater, the following by the Gongyi City, the source of water purification materials plant technology department for everyone in detail. First of all, let's understand the characteristics of some cold drinks factory wastewater: ice cream production is the main raw material maltose, milk powder, chocolate, butter, flavor, product specifications roughly 50-130g and other series of ice cream, the production scale of 4o0 ~ 10 million / year, Raw material consumption is 2OO ~ 500t / year. Raw materials weighing, ingredients, into the sterilization process, sterilization temperature of 8O ℃, time 0.5 ~ 8h. Then after mixing, heat exchange, into the aging process, after aging, condensation forming, packaging, and finally passed the test into the cold storage. Ice cream production in the summer peak season generally 12Od or so, the production of water is divided into raw water, boiler water, wash water, the car asked red water 4 parts. According to the scale of production, the total amount of water for the 375 ~ 598.5t / year, the displacement of 1O5 ~ 293t / year. Production of major pollutants in the drainage COD, BOD from the water into the substandard ice cream, ice cream contains sugar, caramel, milk powder, chocolate, butter, flavor, etc., requiring ice cream factory to strengthen the management of substandard ice cream, into the water Immediately remove, focus on treatment, so that the removal of pollutants, so that the removal rate of pollutants can reach 3O%. Understand some of the characteristics of cold drinks factory, let us look again, the characteristics of polyaluminum chloride, polyaluminum chloride is mainly used for sewage and drinking water treatment, with adsorption bridging role in the water is mainly through the water quality Tiny particles or suspended solids together, thereby increasing its weight to accelerate the precipitation process, in the sewage and drinking water treatment is currently the most widely used water treatment agent is polyaluminum chloride. The cold drinks factory production of waste water, can be said to belong to slightly polluted wastewater, polyaluminium chloride can be very thorough to the cold drink production wastewater treatment to meet emission standards. According to our factory's experience in handling cold water production wastewater over the years, the production of waste water from the cold water treatment plant has special effects. We hope that while dealing with cold drinks, we should forget the treatment of production wastewater and choose the production of polyaluminum chloride for the cold drinks plant Wastewater, I plant the recommended content of more than 28% of the products.
