Biosolve purge sachets are designed to unblock urinals and shower cubicles instantly by breaking down organic waste, releasing enzymes and re-opening the pipe. You will see immediate improvements after treatment. Quadrasan Purge contains a biologically concentrated active powder formulation that is designed to deal with waste products. Using Quadrasan Purge sachets speeds up the degration of paper, protein and waste product. The odours that these produce are reduced. The bacteria in this powder will colonise the waste material such as uric acid, and will degrade the waste until the system is clean. The formulation removes obnoxious odours from the sanitary system and is completely safe to use with no special handling requirements.
