Guigang Lime Plant: Is composite alkali lime

Composite alkali

Guigang Lime Plant: 1. What is composite alkali

Composite alkali, mainly composed of calcium hydroxide, green clay, diatomaceous earth, activated carbon, and saturated alkaline ammonia water. A new type of alkaline coagulation and settling agent with stable structure and performance is mainly made from natural minerals, processed through physical and chemical processing, activated and modified through activation, and enhanced with high-tech modification. It is fully combined with other inorganic bases for digestion, graded and crushed, and sieved.

Composite alkali can replace sodium hydroxide (caustic soda) and industrial soda ash (sodium carbonate). Its advantage is that it is much more affordable and cost-effective than caustic soda and soda ash. The efficiency of composite alkali in treating wastewater can completely replace sodium hydroxide (caustic soda), and even have better therapeutic effects than caustic soda, but the selection of materials is more economical. For example, when treating one liter of wastewater, the dosage of composite alkali is only slightly more than half of caustic soda.

Guigang Lime Plant: 2. Is composite alkali lime

Composite alkali is different from lime. The main components of composite alkali include lime, activated green mud, diatomaceous earth, activated carbon, and other mixtures. Their water treatment applications are mainly used to regulate acidity and alkalinity, but composite alkali has less residue compared to lime and better therapeutic effects.

Lime is a type of air hardening inorganic cementitious material mainly composed of calcium oxide. Lime is a product of high concentration calcium chloride such as limestone, dolomite, chalk, and shells, which is calcined at 900-1100 ℃. Lime is the earliest cementitious material used by humans. Lime has a wide range of applications in civil engineering and can also be used in medicine in China.

Composite alkali is different from lime. The main component of composite alkali is lime, and their water treatment applications are mainly used to regulate acidity and alkalinity. However, composite alkali has less residue compared to lime and has better therapeutic effects.

Composite alkali can replace sodium hydroxide (caustic soda), and its advantage is that it is much more affordable and cost-effective than caustic soda. The efficiency of composite alkali in treating wastewater can completely replace sodium hydroxide (caustic soda), and even have better therapeutic effects than caustic soda, but the selection of materials is more economical. For example, when treating one liter of wastewater, the dosage of composite alkali is only slightly more than half of caustic soda.

The alkalinity of composite alkali is equivalent to that of sodium hydroxide. In addition to adjusting the pH value, it also has the functions of demulsification and enhancing coagulation efficacy. In the treatment of individual wastewater, the effluent is cleaner than using sodium hydroxide, and the therapeutic effect is particularly significant for very complex wastewater (such as circuit boards, electroplating, and other waste gases). In some wastewater, it also contributes to the effectiveness of heavy metal deposition and phosphorus removal. Low usage cost, in line with the high-quality and low-cost production requirements of enterprises, not only can adjust the pH value, but also has the function of breaking emulsions and enhancing the coagulation efficacy of other agents; In the treatment of nickel plating wastewater and other water using this composite alkali, the effluent quality is clearer and the therapeutic effect is more significant compared to sodium hydroxide treatment; As a combination of other water treatment agents, it can enhance the efficacy of heavy metal deposition and phosphorus removal; The cost of water treatment is low, and the cost of treating the same amount of wastewater with composite alkali is lower than that of sodium hydroxide. However, the treatment effect of water treatment is stronger than that of sodium hydroxide treatment, and the treatment effect is more obvious.

Suitable for pH neutralization and alkali treatment of various types of wastewater. Wastewater can be adjusted to the actual required alkalinity by adding alkali, and is commonly used for papermaking wastewater, electroplating waste liquid, chemical waste liquid, papermaking wastewater, etc. Phosphorus removal from wastewater. The large amount of calcium ions rich in composite alkali can react with insoluble phosphorus in wastewater to achieve efficient phosphorus removal efficacy. Eliminate heavy metal pollution. It has adsorption and precipitation effects on most heavy metal substances in sewage. Increase the biochemical anaerobic capacity. Can be used to regulate the growth environment of microorganisms.

Guigang Lime Plant: III. Precautions for Packaging and Storage of Composite Alkali

Single layer packaging using thin film plastic bags, plastic woven bags, or sheepskin bags, with a net weight of 25kg per bag, to prevent rain or mold during storage and transportation. Cannot be stored and transported together with other physical items. The shelf life is three years.

This product belongs to inorganic alkaline corrosive substances and should be stored in a shaded, ventilated, and dry warehouse. The packaging should be intact and sealed, and attention should be paid to preventing mold and moisture, rain, and sun exposure. Prevent contact with acids. Handle with care during loading and unloading to avoid damage to the packaging. When there is a big fire, sand and various fire extinguishers can be used to extinguish it.
