How is the disposal of metal pickling solutions, as well as the disposal of acids and alkalis?

Our Center carries out work on the neutralization of acids, alkalis and waste pickling solutions. For these purposes, industrial treatment facilities are used, based on the reagent cleaning method.

We carry out input control of incoming waste and control of MPC at the output. Accepted waste solutions are deposited. Wastewater treatment from ions heavy metals carried out by transferring heavy metal ions into poorly soluble compounds during the neutralization of wastewater using various alkaline reagents (calcium, sodium, magnesium hydroxides, calcium oxides, sodium carbonates, magnesium).

When acidic wastewater is neutralized with lime milk containing a significant amount of limestone, heavy metal ions (zinc, copper, etc.) are precipitated in the form of the corresponding basic carbonates.

Then the resulting insoluble precipitate enters the press filter, dries, after which it is delivered to asphalt concrete production plants and used as a structuring additive. Thus, it is carried out wasteless technology disposal (neutralization) of such waste.

And one more thing - we have the lowest prices in the region!

Acid disposal is an acute problem for many enterprises. Such aggressive media, even in small quantities, are toxic to the human body. Large volumes of these substances, when released into environment have on her extremely negative impact. Therefore, these are important dangerous substances properly dispose of.

Important! Acids are known to be poisonous. If they are handled carelessly, if they get on the skin or inside the body, burns, severe poisoning and even death can occur.

The process regarding the disposal of such aggressive media in enterprises begins with the tank in which these substances are transported and stored. Requirements for containers for disposal:

1. The conditions for the tightness of the container must be strictly observed (it must be completely sealed), it must be specially marked.
2. The container must be made of a material that is inert to the substances carried in it to avoid damage to the container itself.
3. Do not mix different acids.
4. Transportation of containers with aggressive waste must be carried out by special transport.

Acid waste received for processing is neutralized (neutralized) using reagents, which makes it possible to reduce the concentration of waste compounds to an acceptable level. If the "mining" contains solid impurities, then they should be separated. The separation is carried out using a reaction apparatus, which has a stirrer and a chamber filter press. The sludge from the separation process is usually landfilled. hazardous waste or being buried. The remaining liquid, depending on the composition of the spent acid, is sent for further processing or destroyed.

Waste hydrocyanic acid, hydrofluoric acid, picric acid are also disposed of in accordance with the characteristics of the ongoing process (for each substance) in accordance with all safety regulations. Utilization of nitric acid proceeds according to the general technology described above, taking into account some nuances.

Disposal considerations for other common acidic wastes are discussed below.

The nuances of sulfuric acid processing

How to dispose of sulfuric acid? Indeed, as a rule, in addition to itself, this kind of waste contains many impurities (for example, wastewater). Consider three ways to dispose of sulfuric acid waste:

1. The implementation of the neutralization reaction without the subsequent use of the resulting product. For this purpose, alkalis, strong bases are used.
2. Use of sulfuric acid waste. This method is not widely used due to the presence in such waste a large number impurities.
3. Regeneration of the sulfate mixture in order to obtain a pure sulfate product. For this, methods such as adsorption, coagulation, evaporation, etc. are used.

During the processing, sulfuric acid storage tanks are used, usually made of polymers (polyethylene, polypropylene, etc.)

Features of the disposal of hydrochloric acid

The so-called "hodgepodge" is often used in industry. In this regard, questions arise about how to dispose of hydrochloric acid, how the process is carried out.

Disposal of hydrochloric acid has some difficulties related directly to the process. It must be done according to the following rules:

1. Neutralization. Alkali solutions are used, for example, a 5% solution of calcium hydroxide, etc. It should be noted that the spilled "hodgepodge" can be neutralized with water, which is supplied by watering or fire engines. The soil with the “hodgepodge” that has fallen on it is cut off and then transported to a special landfill.
2. Utilization of a solution of hydrogen chloride in industrial volumes. Simply neutralizing large volumes of hydrochloric acid solutions is unprofitable. It is more economically correct to reuse waste containing “hodgepodge” in production. There are several such possibilities, for example: the production of chlorides of certain metals or the implementation of the isolation of pure chlorine.

Neutralization and processing of hydrochloric acid solution, as well as other acid solutions, are carried out by professionals. Who offers this kind of service? These are usually companies licensed to dispose of hazardous waste. Specialists of such companies neutralize aggressive environments in accordance with all safety requirements.

Acid disposal at home

Some acidic solutions are also used in everyday life. For example, "hodgepodge" is used to get rid of limescale. It is also used to remove rust stains from clothing.

Dilute nitric acid is used in everyday life for cleaning metal products (silver, gold, etc.).

Acetic acid is part of the well-known vinegar and vinegar essence.

How to dispose of alkali in production

Utilization of alkalis is carried out in three stages:

1. Transportation. Spent alkalis are transported to places specially designed for subsequent disposal. In this case, transportation is carried out by transport, which is equipped with specialized equipment. Hermetically sealed tanks with alkaline waste are placed on such transport. Tightness is necessary so that the transported waste does not come into contact with other compounds. These tanks are installed in a vertical position and are numbered.
2. Disposal. A neutralization reaction is carried out using acids. During the reaction, a sufficiently large amount of heat can be released, depending on the selected reagents. In this regard, it is important that the process is carried out by a specially trained person, observing safety precautions.
3. Processing of reaction products. The salts formed as a result of the neutralization reaction are sent for further processing for the purpose of their subsequent use in everyday life and production.

The following short video is devoted to how the acid (at home) used as an electrolyte is disposed of:

Proper disposal of acids and alkalis is an extremely important process to protect natural environment and human health from negative impact aggressive environments. You can dispose of such hazardous substances yourself, but it is still better to use the services of professionals.

However, these chemical substances can be not only helpers, but also enemies.

Alkali is a caustic and dangerous chemical that dissolves well in water and can cause irreparable harm to nature and human health. Neutralization and disposal of spent alkalis is a complex and dangerous process which should be attended by qualified professionals with special knowledge and skills in working with chemicals.

Our company will help to cope with this responsible task. Specialists will carry out high-quality utilization of alkalis in Moscow and the Moscow region.

Thanks to the activities of our company, enterprises of the chemical, metallurgical, food and perfume industries, as well as workers in the medical field will be able to safely and fairly quickly get rid of harmful and hazardous waste.

Alkali disposal - only for professionals

Alkali is dangerous in any form because it contains sodium hydroxide. It is necessary to work with this chemical in overalls and gloves, while the eyes must also be protected. Alkali vapors can enter the human body and cause serious harm to health:

• Penetration into gastrointestinal tract threatens with colic, poisoning and burns of the gastric mucosa.
• The ingress of alkali into respiratory system fraught with coughing and suffocation.
• Skin contact causes burns.

Pour out alkaline solutions in water or on land is strictly prohibited. This can lead to environmental pollution and poisoning of living organisms.

Alkalis are caustic chemicals that pose a particular danger to the environment and living organisms. They have a destructive effect on tissues, leave chemical burns upon contact with the skin, and also cause irreparable harm to the environment. Alkalis are compounds of alkali and alkaline earth metals with the hydroxyl group -OH. They are in the form of solid and hygroscopic substances. white color, which have excellent solubility in water, while releasing significant heat.

Nowadays more and more industrial enterprises begins to actively use alkalis in his work. Typically, after passing technological process these chemicals lose their properties, and therefore become unsuitable for further use.

In accordance with the current legislation, spent alkalis are subject to proper disposal. In other words, they cannot be drained into the sewer, thrown into garbage cans, taken to landfills, forest belts and ravines, as this will lead to soil, water and air pollution. If government agencies find that alkali is not being disposed of, then a large fine will follow. To avoid trouble with regulatory authorities and minimize the risk of environmental pollution, you need to entrust the disposal of such chemicals to professionals.
