There are two types of waterless urinal technology:
- Oil or chemical cartridges - urine passes through a oil or chemical-based barrier which is then supposed to form a seal which reduces odours. Using this system requires expensive cartridges to be replaced every few months, and the maintenance costs are high, particularly since the oil seal can easily be accidentally broken, for example by a cleaner washing a bucket of water down the urinal.
- URIMAT's patented ActiveTrap or so called membrane trap - The membrane trap technology / membrane valve has proven its performace for more than 10 years and is the newest waterless urinal technology. It is much more effective at preventing odours and hygiene issues as well as being significantly cheaper and easier to maintain.
The patented and exchangeable ActiveTrap used in the URIMAT Urinals collects the urine and discharges it (without using water) into the drainage system. No pollutant oils or chemicals are used and no odours can develop.
