The ZeroFlush Peroxetab Saves Water & Treats Urine Smarter
Fast odour neutralisation, safer chemistry, and a superior user experience. These are the unique selling points of the BioPur Peroxetab in the ZeroFlush EnviroSeal Operating System.
Keep your waterless urinals smelling fresh all day. BioPur Peroxetab works inside the ZeroFlush EnviroSeal Operating System to break down odours at the source. It targets biofilm, sulphides and urine scale while lifting hygiene standards across busy amenities.
Treating Urine Wastewater at the Source – Right in the Urinal
Every drop of urine entering a ZeroFlush urinal activates the Peroxetab hydrogen peroxide urinal treatment tablet in the BioPur holder. The tablet activates on contact with urine, releasing hydrogen peroxide that immediately begins to neutralise harmful contaminants and odour-causing bacteria.
Unlike traditional wastewater treatment, which happens far downstream, Peroxetab starts working at the point of generation, preventing pollutants from ever reaching rivers and treatment plants.
Unlike flushing systems that only dilute urine, ZeroFlush with Peroxetab treats urine at the source, the moment it enters the urinal. It stops contamination before it even begins, something flushing urinals can never achieve.
Why Treat Urine at the Source?
Wastewater contamination is rising at an alarming rate:
👉 PFAS “Forever Chemicals” – detected in 95% of sites downstream from treatment plants.
👉 Pharmaceutical residues – antibiotics, hormones, cancer drugs and antidepressants pass through conventional systems.
👉 Illicit drug metabolites – cocaine, amphetamines and other compounds resist standard treatment.

What is the BioPur Peroxetab?
The BioPur Peroxetab is a solid oxygen-releasing tablet designed for use in urinals, cisterns, drains, and vents.
It dissolves in contact with moisture and releases a steady dose of active oxygen through the Elastomer assembly trap and drain waste pipe. That oxygen oxidises odour compounds and helps clean the surfaces that harbour them.
In plain terms: no perfume cover‑ups or masking agents. Absolute odour destruction, then a clean, neutral finish.
The chemistry in brief
✅ Oxygen release oxidises volatile sulphur compounds and amines that cause smell.
✅ Hydrogen peroxide forms in solution and breaks down to oxygen and water.
✅ A mild alkaline pH helps loosen urine scale and disrupt biofilm.
Why it matters for your facilities' urinals
🧼With BioPur Peroxetab, you can ensure a fresh smell consistently, as it stops odour in the trap, not the room. This leads to a better user experience, as staff and visitors often judge cleanliness by smell first.
🚻 Better user experience: Visitors judge cleanliness by smell first. Give them confidence.
🛠 Low maintenance: Long‑dissolving tablet. Fits our EnviroSeal OS in the BioPur kit swap on service.
💧Waterless compatible: Designed for ZeroFlush urinals and retrofits.
🌿Greener sustainable story: Readily biodegradable breakdown pathway. No VOCs.
How the BioPur Peroxetab works inside the EnviroSeal OS
✅ The BioPur holder location sits above the flow path, away from the splash.
✅ Moisture activates the Peroxetab tablet. It releases a controlled stream of oxygen.
✅ Active solution moves through the EnviroSeal’s elastomer trap and wastepipe drain line.
✅ Odours are neutralised as organic compounds are oxidised.
✅ Surfaces stay cleaner, which cuts scale and the chance of blockages.
The result is quiet unasuming reliability. Your urinals work, and they smell right.

FAQS: Your Top Questions, Answered
Does the Peroxetab mask odours with fragrance?
No. It neutralises odours by oxidation. The room smells neutral, not perfumed.
Is it safe for waterless urinals?
Yes. It is designed for ZeroFlush waterless systems and can be utilised in other manufacturers’ urinals, including flushing urinals.
What about transport and storage?
It is non‑flammable and not classified as Dangerous Goods for road transport. Store cool and dry.
Will it harm bacteria in the sewer and in a septic tank system?
No, in everyday use. The dose is small, and peroxide breaks down to oxygen and water as it travels.
How often should we replace it?
Follow the ZeroFlush service interval. Heavy traffic sites may prefer shorter cycles. Generally, in everyday use, it will last 4-6 weeks.
Are there any special disposal steps?
For everyday use, the Peroxetab slowly dissolves. If there is a small amount of the tab left in a BioPur holder, the best solution is to always place it on top of the new Peroxetab so it continues to work its magic. If you wish to dispose of a Peroxetab, then for small amounts, dilute to the point of drainage with an ample amount of water. For bulk quantities, use licensed disposal.
Do I need to wear eye protection and gloves when handling Peroxetab?
BioPur Peroxetab is classed as an eye irritant, so use common‑sense care. Disposable gloves are always the best option, but are not mandatory. If you do happen to get dust in your eyes, rinse with water for 20 minutes and seek medical advice. After handling a Peroxetab, always wash your hands with soap and water. Always follow the product label and your site safety rules.
