Waste treatment

For the treatment of industrial and consumer waste from its clients, West Dala uses the following methods:

  • physico-chemical method - this method, the most common method for treatment of oil sludge, which is based on the processes of mutual dissolution of compounds, which include solvents and the oil products themselves. The intensity increases with heating, after which the solid and liquid phases are separated by filtration, followed by separation of polar (solvent and oil products) and non-polar compounds and the regeneration of the used solvent.
  • biological method - this method of waste treatment is most widely used as microbiological. The ability of microorganisms and their enzymes to consume organic substances of various structures, to decompose or transform natural biopolymers is the basis for obtaining many useful products of microbiological synthesis and waste treatment.
  • thermal method - this method is widespread both in our country and abroad. Its principle is that all organic substances are completely oxidized by atmospheric oxygen at high temperature to non-toxic compounds. As a result, mineral products (in the form of ash and granules), vapors and gases, heat are released.
  • pyrolysis method is the process of thermal decomposition of combustible organic compounds without oxygen. During the pyrolysis, a mixture of combustible gases (synthesis gas) and a number of other products are formed, the composition of which depends on the nature of the feedstock, temperature, pressure, heating rate in the reactor, and residence time in the chamber.

All these methods are used on specialized equipment located in the territories of our company facilities.
