Separation systems from Filtration Group Industrial ensure clean treatment of oil, fuel, bilge and surface water in many applications. The de-oiling or de-watering of contaminated liquids works according to the proven coalescer principle, which does not require the use of additional chemicals and is nevertheless very efficient. Combined with a comprehensive service, Filtration Group Industrial offers tailor-made solutions for the shipping, wind energy and industrial applications.
The turbulence in a separation step separates oil, water and solids in multiphase separation (MPS). The solids slide along the surface of the separation profiles, and the oil collects on the profiles and forms larger drops there. These oil drops rise upward and are dissipated there. In a second stage, the mechanical emulsion and foam breaker (MESB), the coarsely purified water in the coalescer element flows through a microfiber bed, in which even the finest oil droplets are combined and float upwards into the oil collecting dome. With an additional membrane stage the remaining oil contents can thus be reduced to under 1 ppm.
The system is designed to control the residual oil content after the separation of oil-water mixtures and before the water is dis-charged overboard. In addition to compliance with the legally required values of the oil content of Oil-water mixtures on board, the FG Data Logger enables the exact logging of all relevant data. The data is protected against manipulation.
The oil-water separator does important work, especially in industry, with the washing bath treatment, the treatment of industrial wastewater, industrial parts cleaning and process water treatment. It is robust, has a compact housing and is highly effective in single-stage separation under pressure. In power plants, the MESB is also used in the treatment of process and surface water.
The non-pressurized oil-water separator is used for maintenance of industrial washing baths and water-based cooling lubricants, from which external oils need to be removed. After separation, the oil film flows on top of the dispersion medium to the system outlet, where it drains through a height-adjustable groove.
With the two-stage separator, the multiphase separation and the mechanical emulsion and foam breaker are each placed in a single pressure tank. It is primarily designed for the treatment of bilge water and with its modular design is very well suited for retrofitting of old ships.
Multi-phase separation and mechanical emulsion and foam breakers in this deoiler model are divided in two pressure vessels. The separation rate of 5 ppm residual oil content in the bilge water meets the requirements in National Special Areas and Particularly Sensitive Sea Areas, as well as the “Green Ship” and “Green Harbour” limit values.
With this high-performance system, the residual oil content of the exiting water can be reduced to below 1 ppm. The MFEB has a membrane stage downstream to the multiphase separator which separates the remaining water-oil emulsions under high pressure. Oil and other residues are concentrated and recycled.
The treatment of oil and fuels is based on the coalescer process. When the contaminated water swirls, larger drops of water form on the filter surface and sink down into a tank. If a smaller residual water content results, an additional separation system is positioned downstream of the coalescer elements. Here the oil or the fuel flows through a water-resistant membrane, which itself retains very fine water droplets. In this way the residual water content can be reduced down to 70 ppm. The coalescer process makes the use of centrigues or chemical additives unnecessary.
The efficient fuel treatment system prevents concentrations of free water from rising above 70 ppm. It thus acts as an effective protection against the “diesel oil pest”. The single-stage system is used primarily in shipping, preventing engine damage and system failure. Because of its compact design, it takes up little space in the engine room of a ship. In the version as OFWA, the system is also used e.g. for dewatering hydraulic oils.
This two-stage unit filters the fuel as FTS or the oil as OTS before the water separation in the coalescer elements, which increases the performance and service life of the equipment in case of contamination with larger solid particles. The efficiency of the filters in the first stage can be individually adapted to the medium and requirements. There are potential applications in shipping, industry and in power plants.
The PTS / OTS is equipped with additional separator membranes in addition to the coalescer elements. These membranes prevent even the finest water droplets from escaping, which means that the fuel or oil is perfectly clean when it comes out. The system is well suited for protection of gas turbines in power plants and for fuel treatment on emergency power units. The PTS is individually configured for the particular requirements. Filtration Group delivers OTS standard sizes with a flow capacity from 300 to 2000 l/h. Other sizes are available upon request.
Coalescer filters were specially designed for removing water from hydraulic systems. They run cost-effectively and easily without absorbents: Specially configured filter media collect the small water droplets suspended in the fluid and separate them.
The system is the optimal solution in crude oil dewatering. The system combines multi-phase separation, mechanical emulsion and foam breaker (MESB) and membrane filtration in one system and reduces the residual water content to less than 0.1%. The CWD / OTS is primarily used in the oil and gas industry and is individually adapted to the medium and the required purity level. The flow capacity reaches from 10 m3 to 100 m3 per hour. The system can optionally be run in fully automatic mode.
