Water bodies are polluted by oil and petroleum products from various sources. The primary sources are navigation, accidents on ships and coastal areas, industrial wastewater discharges, surface wastewater from settlements, and transportation crossings of water bodies. Reducing the content of oil products in water bodies is an important task of nature protection, requiring the development of new effective methods of wastewater treatment from oil products. A systematic approach is proposed to solve this problem, including analysis of conditions of wastewater formation, study of phase-disperse composition of pollutants and their physical and chemical properties, and analysis of possible water treatment methods. According to the formation conditions, oily wastewater can be divided into domestic wastewater, surface runoff, and industrial wastewater. Depending on the formation conditions, oil products in wastewater are in different phase-disperse states with different sedimentation and aggregative stability values. Separation methods are most effective for sediment-unstable petroleum product systems and are sufficiently simple and reliable. Sedimentation stable systems of petroleum products in water need to be preliminarily destabilized. This is achieved by adding alkaline acids, mineral coagulants, or organic polyelectrolytes. Wastewater characterized by aggregative stable systems of petroleum products can be treated by degradation methods such as ozonation or sorption.

“…Kazan State University of Architecture and Engineering (KSUAE) has developed devices that combine the treatment of oil-containing wastewater in pressure hydrocyclones, succeeded by purification from petroleum products and suspended substances by sedimentation. These installations are called the «hydrocyclone -sump block» (HSB) [10,11]. Coalescing nozzles made of granular materials are used to intensify the deposition of oily wastewater [12].…”

Wastewater treatment of machine-building enterprises contaminated with oils, petroleum products and mechanical impurities is an urgent task. A promising direction in the field of treatment of such wastewater is the use of pressure hydrocyclones and hydrocyclone installations. The article presents the results of research on the treatment of oil-containing wastewater of machine-building enterprises in pressure of hydrocyclones, conducted on an experimental hydrocyclone installation, which includes the pressure hydrocyclone under test, a sedative tank, and tanks for receiving water from the upper and lower drains of the hydrocyclone. The studies were carried out in two stages: the first stage was used to determine the diameter of the pressure of hydrocyclone suitable for the treatment of oily wastewater, and the second stage was used to study its geometric characteristics. At the first stage, seven modifications of pressure hydrocyclones with a diameter of 40 to 100 mm with different diameters of the upper and lower drain pipes were tested. A 75 mm diameter hydrocyclone is recommended for the treatment of oily wastewater. At the second stage, nine pressure hydrocyclones with a diameter of 75 mm with different diameters of the upper and lower drain pipes were tested. As a result of the experiments, the design parameters of the hydrocyclone that showed the best results were determined. The results of the research were used in the design of industrial hydrocyclone installations.

Purpose. Increasing oil recovery from reservoirs, reducing water content, and decreasing costs by pumping formation water effectively cleaned of suspended solids allows you to get a picture of the uniform distribution of water over the reservoir and, in general, the quality maintenance of reservoir pressure in productive reservoirs. Methodology. The study on water treatment issues for maintaining reservoir pressure at existing oil fields has a variety of approaches. Therefore, the methods of analysis, review, comparison, modeling, experiment were used in the work. The analysis method made it possible to divide the problems of approaches to the formation water preparation for its injection into the reservoir into many elements, which made it possible to learn their properties, connections and relationships. This method contributes to a more detailed structuring of the problem of water treatment. The analogy method uses the study of the technology of preparation of reservoir water with suspended solids. Based on the data, an effective technology was studied for treating formation water from suspended solids and injecting it into a productive formation. Findings. The experiments carried out reflect the high-quality water preparation using the developed new industrial sand-gravel filter made of granular materials with variable particle sizes in the vertical direction, taking into account the rational parameters of the column height of the filter working area. The regularities were studied and the process of formation water preparation without suspended solid particles was improved on the basis of the theoretical and experimental studies carried out on a special laboratory unit. The dependence of the reservoir permeability in the bottomhole zone of injection wells on the size of solid suspended particles in the injected water was determined, and rational filter parameters were established for preparing injected water without suspended solid particles into the reservoir using granular materials with a variable fraction and water supply from the bottom up. Originality. An effective technology for deep purification of formation water from suspended clay particles is proposed by using filters made of granular materials with a variable particle size. The technical result of the invention is to increase the efficiency of purification of industrial waste and industrial formation waters with suspended solids. Practical value. A new method for deep formation water treatment is proposed, which ensures the capture of suspended solids. The results of experiments on establishing the regularity of the process of formation water filtration with suspended clay particles through a porous medium with variable pore sizes and granular particles are presented. A recommendation has been developed for choosing rational parameters and operating modes of a new filter for formation water treatment.
