The Bio reme Urinal Bar is combination of multiple bacteria strains specially formulated to reduce odor problem and blockages in urinal pans and when it comes in contact with the urine, the spores in the Urinal screen are activated into ‘good’ bacteria that ‘feed’ upon the waste and then multiply. The urine pushes down the bacteria into the urinal pipe and over a period of 15-30 days a colony of microbes is established in the urinal drains. improve cleaning efficacy to remove fats, uric-scale and solids that build up in urinal traps and pipe-work causing odors and blockages. Bio reme Urinal Blocks contain a selection of non-pathogenic micro-organisms and blend of cleaning and water-softening agents, a special odor-blocking perfume & color. This puts the urinal pipes get into an auto clean mode and reduce any accumulation of scales. Water simply pushes the untreated waste (in this case, urine) into the STP for further treatment. But in this case, it is not needed, as the bacteria neutralize the waste and thus one can afford to go flush-less. Ultimately, the load on the STP is reduced too.
