July 2010First PITT flotation in Romania.
A unit of our DAF 100-1280-series (30 m²/h) has been installed by our Romanian partner ATB. Waste water from a dye works facility in the automotive industry is analyzed and chemically treated prior discharging into sewer.
January 2010First AEROS in Ukraine.
The first AEROS in Ukraine has been installed. With our AEROS technology, it is possible to clean and recycle washing water from a manual car wash installation up to 100 per cent.
August 2009Our PTT DAF-technology “aquaflow” will be marketed worldwide in combination with the proven “Dekanter”, a technology of our partner GEA.
Special leaflets are available on [digestate treatment in biogas plants] and [waste water treatment in refineries].
February 2009Our high-performance separator TPS is launched.
The innovative 3-phase-separator-technology enables concurrent separation of oil and suspended solids from process water in one passage. [more...]
The flexible high-performance separator
The TPS is a system for the physical treatment and recovery of industrial and commercial waste water. Thanks to an optimal utilisation of physical forces and individually adapted streaming technology the three primary phases of a process liquid are efficiently separated.
- Free light liquids of a density < 1 g/cm³
- Process water of a density ~ 1 g/cm³
- Sedimentable pollutants of a density > 1 g/cm³
As defined in the European standard the nominal size of separators and strippers exclusively refers to the maximum influent volume in l/s (e.g. NG10 = 10 l/s). Many other parameters relevant to the physical separation are not considered.
As opposed to the common systems the TPS is exclusively manufactured to the individual technical specifications thereby ensuring the efficient separation of the three phases for their further processing.
The TPS accounts for all parameters influencing the separating behaviour as well as the streaming properties, such as:
- the influent volume
- the maximum quantity of the light liquids
- the density of the light liquids
- the viscosity of the light liquids
- the maximum quantity of the sedimentable substances
- the average density of the sedimentable substances
Further parameters such as the place and temperature of installation, media temperature, chemical composition etc. determine the materials used in construction. The TPS is available in polyethylene, polypropylene, standard steel, stainless steel of various grades as well as in concrete.
Main components of the PITT-TPS (schematic representation)
The water to be treated flows into the 3-phase separator’s (TPS) influent for separating the free light liquids and sedimentable substances.
The first separator stage consists of a capsulated 3-phase separation chamber containing a hydrodynamic flow distributor in the influent. This avoids unwanted eddy flows and facilitates the phase separation.
The sedimentable substances sink in the lower static area of the hopper-shaped sludge collection chamber. The separated slugde is directly discharged via the sludge effluent by means of a suitable pump so that it can be further processed.
The water containing the light liquids flows out of the 3-phase separating chamber into the above light material separation stage. Within the static area of the separation stage the light liquids are dewatered and are drained for further processing via the light material effluent.
By means of a defined hydro-dynamic reverse flow the purified water is fed to the TPS’s effluent.
