The NaRQ unit consists of two components: the toilet and the separation unit. These can be kept in separate rooms, allowing suspects to be confined without monitoring while staff work.

NaRQ can be used in a variety of settings: in airports and other border crossing stations, in prisons and police holding centres and in any other controlled environments where there is a risk of drugs and other banned substances can be brought in.

The Toilet Unit
This consists of a WC and a podium, both made of stainless steel. The WC is wallmounted approximately one metre above the floor, the extra height ensuring the most efficient flushing. The podium allows the suspect comfortable access to the WC.

Both parts are made of stainless steel for maximum durability. As there are no sharp edges or loose fittings, there is nothing that can cause injuries.

The toilet unit is normally installed in a separate but adjacent room to the separation unit, but both units can be kept in the same room.

The Separation Unit
The separation unit houses the unique functionality of NaRQ. This is where staff monitor the recovery cycle and retrieve any recovered objects.

The separation unit is connected to the toilet unit. It contains the central wash chamber, where the waste is processed, a drain and various access and monitoring points.

The wash chamber is fitted with nozzles for water and disinfectant, as well as a camera connected to a LCD screen. There is an observation window placed directly above the wash chamber and a transparent access hatch to the front of the separation unit.

Inside the wash chamber is the collection container.

The Recovery Cycle
The NaRQ recovery cycle has 3 steps: separation, disinfection and drying. From start to finish, the process lasts for approximately 20 minutes.

No manual handling is required.

Step 1 – Separation

When the toilet is flushed, the contents in the bowl are flushed into the wash chamber of the separation unit. Water washes through the chamber, separating waste from any foreign objects.

The contents in the chamber rotates under pressure from the water. Organic substances, i.e. waste and toilet paper, break down into smaller pieces, which are washed into the drain. Non-organic substances gather in the central collection container.

Step 2 – Rinsing

During the final part of the separation phase, disinfectant is mixed with the water in the wash chamber. Any objects left in the chamber are sanitised and any odours are eliminated.

Steps 1 and 2 are repeated three times 3 minutes apart to ensure that all foreign objects have been treated.

Step 3 – Drying

At the end of the recovery cycle, the foreign objects are dried with warm air. After drying, the collection container is transported to the front hatch in the separation unit. Any foreign objects can now be processed as evidence.

The Cleaning Cycle
NaRQ features an automatic cleaning cycle for the separation unit. The cleaning cycle lasts for approximately 90 seconds. Once completed, the wash chamber and other parts of the separation unit are clean, sanitised and refreshed. The cleaning cycle not only removes bacteria, but also eliminates unpleasant smells.

Each recovery cycle should be followed by a cleaning cycle, to ensure a hygienic working environment.
