Wastewater treatment in Ukraine

The surface of the globe is 75% covered with water. But only 2% of the total water cover is fresh and habitable. Directly the water cycle in nature creates the required conditions for the existence of living beings on earth. The growth in the number of settlements with the improvement of living conditions, the intensification of the development of various industries lead to an aggravation of the problem of water supply. Thus, monitoring the quality and reducing the amount of discharges of untreated wastewater is one of the main tasks today. To reduce the harmful effects of industrial and agricultural use of water on the ecology of the globe, deeper wastewater treatment is needed. Measures aimed at protecting, purifying water from various contaminants, as well as its rational use will help keep the world’s water cover clean.

Wastewater treatment in Ukraine involves several methods: mechanical; physicochemical, biological.

One of the most advanced methods of biological wastewater treatment is the Membrane Bioreactor (MBR). In treatment complexes using membrane bioreactors, the same biochemical processes occur as in classical treatment facilities. The difference between treatment plants with MBR and the classical scheme is that the activated sludge separation unit in the secondary clarifiers is replaced by filtration through polymer membrane elements, which guarantees the absence of mechanical impurities in the treated water and does not require additional post-treatment.

The use of MBR for wastewater treatment in Ukraine allows increasing the concentration of activated sludge in the aerotank to 8-14 g/l (in the classical scheme 2-4). At the same time, the age of activated sludge can reach 45-60 days, which in turn contributes to a more rapid decomposition of complex organic contaminants and significantly reduces the amount of excess sludge. Thus, by increasing the concentration of activated sludge, treatment facilities using MBR require two to three times less area than classical ones.

Wastewater treatment with membrane elements

At present, wastewater treatment in the world involves the use of two types of membrane elements for MBRs, namely:

  • capillary;
  • lamellar.

Membrane bioreactors can be:

  • with submersible membrane elements;
  • with remote membrane elements.

Also, membrane elements differ in filtration rating:

  • ultrafiltration;
  • microfiltration.

The advantage of the first type is that it does not require additional disinfection of treated water, the second type – the possibility of implementing the operation of the installation in the gravitational mode, which reduces energy costs.

Based on the foregoing, the following strengths of wastewater treatment equipment using membrane bioreactors can be distinguished:

  • the minimum possible area of treatment facilities while maintaining the quality of treated water at the outlet (for example, treatment facilities with a capacity of 200 m3 / day with MBR occupy an area of 30 m2, while treatment facilities according to the classical scheme are at least 120 m2);
  • complete absence of unpleasant odors during the cleaning process (makes it possible to implement cleaning installations in close proximity to residential premises, however, such solutions are prohibited by the regulatory framework of Ukraine);
  • increasing the productivity of existing treatment facilities without increasing the occupied area (reconstruction of treatment facilities by increasing the concentration of activated sludge in the aerotanks and the use of membrane modules).

Wastewater treatment in Ukraine using a membrane bioreactor is the best option for new constructions (for example, boarding houses and recreation centers in the coastal zone) with full or partial treatment, as it takes up much less space.

Our company is ready to develop a design solution with a comparison of methods in terms of operating and capital costs, and then implement the solution chosen by the Customer.
