NEW HYDRAULIC FILTERS, DEVICES, AND INSTALLATIONS
FOR INDUSTRIAL SEWAGE PURIFICATION
V. V. Burenin
New designs for improved hydraulic ﬁ lters, devices, and installations for puriﬁ cation and neutralization of
industrial sewage are considered. The basic tendencies in the development of designs for hydraulic ﬁ lters,
devices, and installations for sewage puriﬁ cation and neutralization are discussed.
Keywords: sewage, hydraulic ﬁ lter, device, installation, puriﬁ cation, neutralization, design, environmental
protection, industrial plant.
The pollution levels of aquifers rise with each year. Oil and oil products are extremely hazardous pollutants for aqui-
fers because they form various types of pollution, e.g., oil slicks ﬂ oating on water, oil products dissolved or emulsiﬁ ed in water,
heavy fractions settling on the bottom, and products adsorbed on sediment. Moreover, industrial sewage contains (at hazardous
concentrations) other pollutants of various physical natures such as suspended matter, heavy metals, surfactants, phenols, acids,
bases, and resins. Any industrial process should be as safe as reasonably achievable with respect to environmental impact on
the area affected by the industrial plant. Therefore, the industrial processes should be closed-loop or nearly so.
The following sewage treatment methods are used because pollution of industrial water during processing is current-
ly not completely avoidable:
• mechanical (sieving, ﬁ ltration to remove suspended solids and plastic particles using a grid, sieve, grease and oil
• forceful (gravitational, centrifugal, electrical ﬁ elds);
• chemical (isolation of pollutants via reactions between them and added reagents to form new compounds separated
• physicochemical (removing pollutants by changing their phase state);
• biological (based on the abilities of several microorganisms to feed on organic and inorganic substances dissolved
• thermal (total oxidation at high temperatures (combustion) of pollutants to produce gaseous combustion products
and solids); and
• combined (multi-stage puriﬁ cation using various methods for purifying sewage).
The method for purifying and neutralizing industrial sewage is selected depending on the required purity levels,
physicochemical properties of pollutants contained in the sewage to be puriﬁ ed, location of the installation, operating condi-
tions of the puriﬁ cation devices, and other factors .
Recently, leading Russian and foreign companies have developed, patented, and manufactured newly designed ﬁ lters
and puriﬁ cation devices with improved characteristics.
A mechanical granular packed ﬁ lter-adsorber had expanded functional capabilities and high-quality puriﬁ cation of
industrial sewage . It consisted of a cylindrical casing 1 (Fig. 1) with upper 3 and lower caps 12, pipes 4 (for initial sewage
input) and 13 (for withdrawal of puriﬁ ed sewage), and protective grid 5. Filtering screens 6 and 8 were provided. The ﬁ rst
