ULTRAAQUA · UV DISINFECTION FOR CORROSIVE AND SALINE WATER
NON-CORROSIVE PP Series
Closed-vessel UV systems with non-metallic reactors for seawater, warm salt water and other corrosive fluids. Polypropylene (PP) reactors as standard, high-density polyethylene (PEHD) as a material option.
Pricing on request.
Overview
The NON-CORROSIVE PP series uses a reactor made from UV-stabilised polypropylene in place of a stainless-steel chamber. The material withstands warm salt water and other corrosive media and copes well with temperature and pressure, which makes the series a good fit for marine aquaculture, aquariums and industrial water where a steel reactor would corrode. The reactors are compact and light enough for wall or floor mounting.
Ozone UV Solutions supplies NON-CORROSIVE PP systems as an authorised ULTRAAQUA reseller and supports them locally: from sizing and installation through commissioning, servicing, lamps and spare parts.
Key features
- UV-stabilised polypropylene reactor for corrosive and saline water, with a PEHD reactor available as an option
- ULTRATHERM low-pressure high-output amalgam lamps, 220 W or 350 W, with a rated life of 16,000 hours
- Sizes from 1 to 20 lamps with flanged connections from DN80 to DN300
- Non-corrosive PTFE UV intensity sensor and 50–100% variable lamp power on all models except single-lamp STD units
- Optional automatic ULTRAWIPER™ cleaning of the quartz sleeves and UV sensor
- PLC control with ULTRATOUCH touchscreen and Modbus TCP/IP or PROFINET on models with three or more lamps
Typical applications
- Recirculating aquaculture systems (RAS), shrimp and prawn farming
- Public aquariums and zoo life-support systems
- Food and beverage, and oil and gas applications
- Removal of residual ozone from ozonated seawater (PEHD reactors)
PEHD reactor variant
The same range can be supplied with a reactor made from high-density polyethylene (PEHD). PEHD tolerates temperature swings and resists pressure, salts, acids and oils, which makes it the material of choice for highly corrosive industrial and aquaculture duties. It is also suited to breaking down residual ozone in seawater that has been treated with ozone. PEHD reactors can be fitted with a non-corrosive PTFE or a corrosion-resistant ÖNORM M 5873-1 certified UV sensor, together with the ULTRAWIPER™, which allows routine maintenance checks to be limited to once a year.
