Technological regulations for wastewater treatment

1. Mechanical cleaning with dehydration of the separated large fractions

Provided by the use of rotary drums with the ability to trap particles larger than 1 mm, which reduces the load on the oxidation reactor. The coarse fractions separated at the first stage are sent to a screw separator, followed by dehydration to 30–35% and disposal in the container.

2. Purification with an AQUA-OR reagent unit with a controlled oxidation process of the first purification stage

Purification at this stage occurs as a result of supplying the reagent to the effluent while simultaneously raising the pressure in the water-air mixture system and oxidizing the effluent using an injection system with variable pressure.

3. Additional treatment in the reagent unit “AQUA-OR” with a controlled oxidation process of the second stage of purification

Further purification in the second stage unit is carried out by means of additional oxidation (dissolving oxygen in water) and supplying reagents that neutralize the residue of chemicals in the pretreated water.

4. Cleaning in a floating-load filter with hypochlorite disinfection

The final stage of purification is the passage of purified water through a filter, self-flushing pressure head, with a floating load and disinfection with hypochlorite

Purification of drinking water by oxidation
by original technology
LLC AKVAMEKHANIKA

The oxidation treatment is a very efficient and cost-effective way to purify drinking water, while the original technology of AKVAMEKHANIKA LLC, used in the production of opv-2 (s), allows you to organize the production of oxidative reactors (mobile, based on semi-trailers tractor units and stationary) on an industrial scale.

In the next few years, a significant increase in drinking water consumption is expected, due to an increase in the global population. Due to the fact that the productivity of drinking water sources is usually limited, and the sources themselves are polluted, there is a need to use effective cleaning systems.

Traditional physico-chemical purification methods, such as flocculation, filtration and chlorination, are often not enough to ensure proper quality and safety of drinking water.

The air / water mixture system developed by AKVAMEKHANIKA LLC is one of the most effective oxidizing agents, ideal for water treatment. This device directly affects impurities and contaminants, dyes, sources of odors and microorganisms without the formation of harmful byproducts or residues.

Modern drinking water treatment plants can acquire significant advantages using the oxidation reactor in various technological purification schemes. A continuous process controlled oxidative reactor provides:

  • Control of taste and smell;
  • Bleaching;
  • The destruction of algae;
  • Impact on colloids and suspensions (improved flocculation and filtration);
  • Oxidation of trihalomethan starting products;
  • Oxidation of iron and manganese;
  • Pesticide removal;
  • Oxidation of impurities, such as: cyanides, phenols, drug residues, endocrine disrupting substances, chemically resistant substances;
  • Control of the content of humic, fulvic and tannin acids;
  • Disinfection and control of the virus population;
  • Destruction of cryptosporidium;
  • Oxidation of organic substances before water supply to the filter with floating loading.

In the preparation of drinking water quality, it is vital to disinfect it and control the virus population. Almost all water treatment plants in Germany, as well as in most other European countries, use ozone at the oxidation stage, which is very expensive, and the effect, in comparison with the technology of LLC AKVAMEKHANIKA, is the same.

When disinfecting in an oxidation reactor, destruction or violation of the integrity of the bacterial cell wall occurs. This process is called cell lysis. The disinfection mechanism is significantly different from chlorination. Chlorine penetrates through the cell membrane of bacteria, leading to their death, by affecting the enzymes. The differences between oxidation in the reactor and chlorination, associated with the disinfection mechanism, explain the fact that the disinfection rate in the reactor is much higher and more efficient than chlorine.

In tab. 1 shows the results of the control of three types of pathogens. The highest dosage of water-air mixture (0.5 g / m³ of water) is required for the destruction of the Parvum cryptosporidium, a fairly stable single-cell parasite. Having a value of C * T = 5, we get the time required for the destruction of more than 99.99% of parasites, corresponding to 10-20 minutes. The dosage of chlorine required to obtain a similar reaction time, approximately 300 times the dosage of water-air mixture.

Such an extremely high dosage of chlorine can cause the formation of chlorine-containing by-products of high concentration. On the other hand, low dosage of chlorine may not be enough for high-quality disinfection.

The only acceptable norm for the destruction of viruses is their complete absence, since the minimum dose required for virus infection is one plaque-forming unit (PFU). Intestinal viruses and hepatitis viruses can survive for a long time in clean water reservoirs (RF). The most common chlorination of drinking water today is not able to reduce the population of viruses to an acceptable level, and the effectiveness of inactivating viruses by oxidation has been confirmed by many scientists in the world.
