PP Series

ULTRAAQUA’s polypropylene (PP) closed reactor series offers very high quality at a reasonable price. They are extremely versatile due to their corrosion-resistant construction and a flow range from 5 to 1000 m3/h. As a result of attractive price/performance ratio and excellent long term experinces many customers select PP reactor based systems also for fluids that are non-corrosive. The major benefits are:

  • Rigid, corrosion-resistant construction for very harsh enviroments
  • Simple installation, simple operation and maintenance
  • Available with standard or advanced control cabinets
  • Optional UV monitoring with digital UV Önorm approved sensors
  • Available with DIN or ANSI flanges
  • No tools needed for scheduled maintenance

Please note that the PP reactors are not only suitable for sea water disinfection.

PP has a very high chemical resistance. It is resistant to organic solvents as well as acids and alkalis. Polypropylene has a design stress of 1,000 psi at 22.7°C (73°F), and has proven to be an excellent material for laboratory and industrial drainage pipe where mixtures of acids, bases and solvents are involved.

Please note that polypropylene should not be used in contact with strong oxidizing acids, chlorinated hydrocarbons and aromatics.

WHAT TO CONSIDER

productLineConsiderationIcons1

PP or SS reactor ?

Our UV systems based on PP material are completely corrosion resistant. They can be used in all water salinities at temperatures up 80 ºC. However, please note that our range of stainless steel UV reactors are made of high grade AISI316L steel which have been passivated and electropolished internally as well as externally. Corrosion resistance are very high for these as well. As a rule of thump choose PP reactors if sea water temperatures exceed 25 ºC. For special media or applications please contact our engineers for more information.

UVT – UV transmittance of the water/fluid

UV transmittance is the fraction of electromagnetic radiation at 254nm that passes through a water sample of typically 10mm length (UVT10 or T10). In relation to UV-system sizing this parameter is as decisive as water flow rate. In general, the higher water quality, the higher UVT. However, water that looks very clear can have low UVT if it contains certain dissolved substances such as iron and manganese. 

Ultraaqua will free of cost measure UVT or we can estimate it based on our vast experiences. For low UVT applications (UVT < 70%), please consider ACN series.

Pre-filtration

Large particles may serve as protective vessels for smaller microorganisms. In fact most microorganisms often live together in clusters. Required UV dose to inactivate organisms freely suspended in the water is significantly lower compared to organisms of the same specie residing in large particles. For this reason prefiltration may be required. Based on our experiences we generally recommend 50 micron prefiltration. Please note that small concentrations of large particles are very difficult to measure. Turbidity and UVT measuments are generally dominated by smaller particles or dissolved substances, respectively. In most cases, money are well spend on pre-filtration prior to the UV radiation, and UV systems should always be installed down flow of filtration.

Even bigger systems …

Ultraaqua can produce optimized custom made UV-systems based on your specific requirements. As an example we can deliver UV-systems with customized connection sizes and/or orientation of connections (L, Z or angled configuration). We can also produce systems even bigger than the standard stocked systems (standard systems, see below tables). It is possible to combine control panels for installations where multiple UV-reactors operate simultaneuously. Please contact Ultraaqua representative or Ultraaqua directly to discuss the various possibilities.
