Floaters

Pressure floaters are one of the main facilities for removing hardly soluble contaminants: petroleum products, oils and fats of animal and vegetable origin, heavy metals, surfactants, suspended solids, and for separation of the sludge mixture after biological treatment.

They consist of a receiving chamber, a mixing chamber, a flotation cell, a sludge zone, sediment bins and purified water bins. Equipped with a mechanical scraper conveyor, placed on a frame structure with an electric motor-reducer mounted on it. The latter provides the speed of movement of the working tape of the scraper along the "mirror" of water no more than 10 mm / s.

To remove "heavy" fractions, the flotator can be equipped with a screw pump, mounted under the receiving chamber.


Principle of operation

Water enters the receiving chamber of the flotator. After intense turbulent mixing, the water enters the flotokamer, in which, by reducing the pressure to atmospheric pressure, dissolved air is released in the form of tiny (50-100 μm) bubbles and, in fact, the process of flotation of the contaminants. At the interface of the phases (water-air), colloidal particles of contamination are trapped by air bubbles, their combination into larger clusters and removal to the surface in the sludge zone is happening.

To increase the efficiency of work and prevent the breakthrough of flakes, the sludge zone is equipped with a thin-layer module. The sediment formed in it accumulates in the hopper and is periodically pumped out by the slurry pump into a special container.

The "Decanter" NGO serially produces flotators with a capacity from 5 to 100 cubic meters per hour.


Radial Thickeners

Thickening agents (sealers) of sludge and silt are widely used in the structure of treatment of technological and other wastewater.

They are usually installed in front of mechanical sludge dewatering installations: frame filter presses, belt filter presses and centrifuges in order to achieve a higher sludge concentration prior to the dewatering step and reduce sludge volume for processing.

At metallurgical plants, thickeners are used to reduce the amount of abrasive scale before being fed into decanter centrifuges, and also to treat the sludge before burning it in biogas plants.

The radial thickener is a cylindrical container in the center of which there is a bridge with an electric drive rotating sets of plates (troughs). The bottom of the container has a conical shape, and the packs of plates are designed to gradually thicken the sediment to its center.

The unit is equipped with a set of protective automatics providing for raising the tine arms in case of accumulation of pulp and increasing the load on them.

Possible variants of execution:

  • Diameter 6 - 18 m
  • Drive type - Central with gear

Gravidynamic separators GDS

Gravidynamic separators are designed for separation of two liquids that have different density and that are present as emulsions. Usually they are used for separation of hydrocarbon mixtures or plant oils with water. Main fields of implementation are purification of discharged waters form oils and oil products; regeneration of washing and technological liquids in machine-building and maintenance enterprises; collection and removal of water from oil products including cleaning of tanks and liquidation of flows. Gravidynamic separators GDS are unique units developed by NPO Dekanter, LLC team, which have no equivalents in the world in terms of modeling, adaptation and debugging. This unit can be described as follows: emulsion going through a complicated internal structure of GDS unit makes the liquid drops coalescing (adhesion of drops while contacting inside the moving environment) with gradual advancing of more solid liquid with less liquid, and separation at the output of separator with the crossflow center. It results in two separated liquids going from the output of different nozzles.

GD separator can be used as independent equipment or in combination with other units as a device for preliminary separation of the main part of oils and oil products Construction of GD separator can contain heat exchangers to keep the temperature of separated mixture within the set limits. In case of high level of mechanical admixtures GDS of the second generation can be used. These GDS are able to collect and accumulate mechanical admixtures by means of prismatic bottom with the following removal of admixtures from separator; these separators have integrated nozzles for cleaning of the bottom.

At metallurgical plants, thickeners are used to reduce the amount of abrasive scale before being fed into decanter centrifuges, and also to treat the sludge before burning it in biogas plants.

Standard GDS are available with capacity of 1, 2, 4, 5, 10 and 20 m3/hour. Upon request of the customer it is possible to produce GDS of any capacity. Minimal differences of densities of liquids in emulsion required for operation of separators comprises 5%. Residual water content in oil products depends on many factors and vary from 0.5 to 5%. Working range of temperatures start from the top point of emulsion freezing and is limited to 100-120°С. Input power pressure is atmospheric. The units with the higher pressure are available upon request.


Mechanical screen filters

NPO "Decanter" produces mechanical grids of several types: plow, drum and step grinders.

The plundering grid is a filter cloth, taken from the rods, inserted into the frame, above which the plastic chains of stainless steel move along the polymer guides. On the chains are fixed transverse rakes, designed for constant cleaning of the filtering cloth.

The rods of the filter grid have a close-to-drop-shaped cross-section, which improves its hydraulic characteristics. The grate on the special stand is fixed in the channel and can be lifted for maintenance.

In the gratings of the drum type, wastewater enters the interior of a rotating drum with perforated walls, installed at a small angle. Due to water losses through perforated walls, the flow of waste water is concentrated and removed from the opposite part.

Installations in which waste water consistently pass through a set of cloths with decreasing from a step to a step holes are called step grids

All the mechanical grids of the NPO "Decanter" are made of corrosion-resistant steel, in several sizes, which are calculated based on the required throughput, the composition of waste water and the geometric dimensions of the supply channels.


Oil traps

Oil catchers (oil traps) with a capacity of several hundred liters to hundreds of cubic meters per hour are the optimal solution for combined treatment of effluents from petroleum products (gasoline, kerosene, oils, etc.), vegetable oils and partially suspended particles. Actively used in manufacturing plants, gas stations and car washes, oil depots and other facilities.

By efficiency, the oil catchers are close to gravitational-dynamic separators, however, unlike the latter, they have a simpler design, are cheaper to manufacture and are, as a rule, executed for underground installation.


Aerotanks

Aerotank - the main structure used for biological treatment of wastewater. Neutralization of effluents occurs due to the vital activity of the active silt - the biocenosis of bacteria and protozoa.

Due to the saturation of the aeration zone with air, the "active sludge" in the aeration tank is always in a suspended state, sorbing and decomposing into the simplest safe components most of the complex organic and inorganic contaminants during its life.

After the aerotank, the activated sludge enters secondary sedimentation tanks, where it precipitates, after which its excess is sent to the sludge treatment facilities.

To remove phosphorus compounds and improve the sedimentation properties of activated sludge, specific reagents, aluminum or iron salts, can be added to the mixture entering secondary sedimentation tanks.

A distinctive feature of the aerodynamics of the NPO "Decanter", in comparison with traditional plants, is the ability to maintain a high concentration of activated sludge, oxygen content, and, accordingly, the efficiency of the installation.


Modules for centrifugal separation and purification of drilling and oil sludge MC series

The units of the MC are modular systems that are mounted on an open frame or standard shipping containers that allow for working offline and having the opportunity of mobile transport to the venue of the required range of works. Depending on the configuration, they can perform the following types of separation: separation of solids from liquids (sludge thickening), a rough separation of liquids with solids separation, fine separation for the final purification of the release of water, hydrocarbons and other liquids.

As separation equipment used decanters and disc stack centrifuge from three leading European manufacturers: Alfa Laval, GEA/Westfalia and Flottweg.

The minimum equipment, which can be delivered within the module MC: decanter centrifuge or a centrifugal separator feed screw pump, screw conveyor or shnekovo-screw pump for the selection of a dedicated solid phase, piping, fittings and equipment. Top of the range - is not limited.
