Our Biological Urinal cubes deliver large numbers of application-specific organic waste-degrading bacteria.
The cubes also contain the latest eco-friendly scale prevention technology to reduce inorganic and organic scale build-up in urinals, traps associated pipe work.
The removal of this scale prevents the formation of odors at source.
Experience has shown that the frequency of urinal flushing can be reduced, possibly as far as one to two service flushes per day, offering the opportunity for significant water cost savings.
Each Urinal cube weighs 33 grams is approximately 30mm in each dimension.
Dosing: One Bio-urinal cube is placed in each urinal and will last 2-6 weeks. In case of troughs, approximately every 50cm, and then change every 2-6 weeks or when cube has been reduced to less than one quarter of the original size.
During use the cube slowly dissolves, delivering a combination of application-specific bacteria and eco-friendly scale prevention technology which, in combination, massively reduces inorganic and organic scale in urinals, traps and associated pipe work.
Note that this product is not intended to compete directly with traditional chemical (PDCB) toss blocks where a pile of blocks is placed in each urinal and is then replaced frequently.
Our urinal Cubes are scientifically formulated so that one cube treats one urinal for up to 6 weeks.

Inorganic Scale:

Inorganic scale is a much more complex science, consisting of simple compounds from the flush water such as calcium carbonate (the scale found in kettles in hard water areas) plus more complex inorganic combinations, such as struvite.

Struvite is a compound called magnesium ammonium phosphate.

The magnesium and phosphate are present in the water and the ammonia comes from breakdown of the compounds in urine.

The scale forms as a regular lattice, represented by the brown balls in the right hand diagram above.

Rather than attempting to bind every inorganic scale forming element, Bio-Urinal cubes contain a scale prevention technology.

The scale prevention material is represented as the blue lines in the right hand diagram above.

It lies within the scale structure (brown balls) preventing the formation of rigid scale lattice, as would occur in an untreated situation (right hand diagram).

Although some deposits may still form, they are soft in nature and are more easily remove by cleaning or by the flush water.

Prevention of struvite scale

The scale prevention technology prevents the formation of simple and complex inorganic scales; a few parts per million of the active substance resulted in a 94% reduction in struvite formation.
