Neutralisers & systems

Odour neutralisation, engineered

Our essential-oil neutralisers don't cover a smell with a stronger one — they combine with odorous molecules in the air to form new compounds with no odour at all. H₂S, most mercaptans, ammonia and most amine odours can all be effectively neutralised. The systems below are the delivery methods we design, build and install to get that chemistry to your odour source.

High-pressure fogging systems

Neutraliser solution is dosed, mixed with water and atomised at high pressure through stainless steel nozzles — producing droplets as small as 10 microns for maximum contact with odorous gas.

  • Systems accommodate more than 300 nozzles
  • 240 metres of nozzle line installed in under 40 minutes
  • Base units sited and commissioned in under an hour
  • Diverse applications: evaporative cooling — proven at a waste-to-energy plant where gallery temperatures exceeded 45°C

Mobile & stand-alone atomiser units

Workshop-built units that go where the odour is.

  • 2,000-litre site-tow units — flotation tyres, telescopic mast, atomiser height of almost 5 metres, 360° rotating fan assembly
  • 1,000-litre highway units — brakes and lighting for road use
  • Stand-alone post-mounted units — connect water and power, push start; oscillating models cover the work of up to four static units
  • Rotary atomisers: droplets from 35 microns, under 300 watts per atomiser, motor life over 30,000 hours

The Dry Vapour system

Odour neutralisation with no water, no wetting and virtually no maintenance — operating at a molecular level from as little as 60 watts.

  • No storage tanks, no dosing equipment, no water supply
  • Suitable for buildings, open yards, exhaust stacks and ventilation systems
  • Immediate impact on deployment; non-toxic and non-corrosive
  • Proven at waste transfer stations, EfW and rendering plants across the UK and Europe

The ODS-20 range

The ODS-20 product range — IBC and drums of neutraliser concentrate

ODS-20 neutralisers

Bio-organic formulations that accelerate natural biodegradation — surfactants trap odour compounds while pre-formed enzymes break them down at source. 100% biodegradable, harmless to people, animals and the environment, and effective at low concentrations. Simply dilute with water. Specialist formulations include ODS-20 LCH for leachate lagoons and ODS-20 FD for food waste.

DV Gel Odour Neutraliser — branded tubs, one open showing the yellow gel beads

DV Gel Odour Neutraliser

A passive tub of gel beads that neutralises malodour wherever it’s a problem — kitchen extraction, offices, washrooms and toilets, plant and process extraction systems, and more. No power, no water, no installation, guaranteed four-week life — powered by Neusol DV, exclusive to us in England.

Dust suppression

Dust, brought down

Airborne dust is a health exposure, a visibility hazard and an emissions issue rolled into one. Our systems capture dust at the point of generation — droplet size tuned to bind to airborne particles and bring them to ground, using a fraction of the water of conventional dousing.

Rain guns for aggregates & quarrying

High-throw rain gun assemblies covering stockpiles, crushing and screening operations and large open processing areas — robust, simple, effective.

  • Stockpiles and open storage
  • Crushing, screening and material transfer points
  • Large-area coverage from a single assembly

Mobile dust cannons & misting

Rapid-deployment cannons and atomised misting lines for the dust sources that move — working faces, haul roads and temporary operations.

  • Haul roads and site entrances
  • Waste transfer and processing halls — combined dust and odour treatment in one system
  • Variable droplet size: fine for airborne dust, larger where a degree of wetting is required
  • Available to buy or on weekly hire

Biological treatment

Bio-Block & SWG — FOG treated at source

Fat, oil and grease build-up clogs sewers, corrodes networks, generates H₂S odour and drives up tankering and maintenance costs. Our Bio-Block and SWG biological treatments put the problem to work against itself — colonising the grease with bacteria and enzymes that break it down continuously, with no power, no dosing equipment and no hazardous chemicals.

Bioremediation

Enzymatic treatment — a twenty-year passion

The use of enzymatic products is, undoubtedly, an area of customer scepticism. Yet recent reports have shown the efficacy of Effective Microorganisms (EM) in breaking down the fat, oil and grease in our public sewers — the giant "fatbergs" that cause so many blockages.

Odour Control Ltd has been active in this area for the last twenty years, working with several industry experts to tailor solutions to specific substrates. Honestly? It's a passion — and we'd love to discuss any query you have, and to convince you of this planet-saving technology.

How the Bio-Block works

A cylindrical block of aerobic and facultative bacteria, enzymes and micronutrients, suspended in the wet well in a nylon mesh. The kick-start treatment — water-soluble pouches applied over the first weeks — colonises the grease itself, so the bacteria stay in contact with the FOG rather than being pumped away.

  • Continuous passive operation — no dosing equipment, power or storage
  • Reduces H₂S formation, corrosion and odour at source
  • Fewer tanker movements, fewer maintenance hours, less foam
  • BOD entering the works reduced by up to 30% — roughly 1.7 kWh saved per kg of BOD degraded

Biological vs chemical treatment

Chemical dosing for H₂S and FOG — ferric chloride, permanganate, nitrates, peroxide — demands storage tanks, dosing plant, continuous tanker traffic and hazardous handling. SWG biological treatment needs none of it: small manual doses, effects that persist for days after dosing stops, and a sewer network that starts working as an extension of the treatment plant. It degrades the fat rather than fighting the symptoms — and it costs significantly less.

Olfactometry & surveys

In-field olfactometry & reporting

Malodour emissions from waste processing are often a contentious and litigious issue. A complaint can be upheld on the subjective opinion of a single complainant, with no scientific basis beyond one person's sense of smell. Our in-field assessment and reporting service exists to rebalance that situation — introducing empirical data to quantify what is actually crossing your boundary.

Trained operatives carry out a full inspection of the processing facility and measure migrating emissions using the latest in-field olfactometry equipment (the Nasal Ranger, St. Croix), producing objective data to quantify any identified arisings.

What the service includes

A complete assessment, from site visit to hearing

  • An initial site visit to determine a suitable framework for assessment
  • A prescribed duration of olfactometry and level recording
  • A full written report — including the accrued data and general findings
  • Recommendations for abatement and future standard operating procedures (SOPs)
  • Attendance at meetings with relevant authorities or agencies, and representation of your organisation in public-liaison or planning presentations
  • Further real-time monitoring services through our close working relationship with Sentinel Online

This service has been used extensively in the UK, Ireland and West Africa, and has often proved imperative in the successful defence of a complaint or non-compliance.

Complaints, permit pressure, or just not sure? Get it measured.

An odour survey is often the fastest route to the right answer — and the cheapest.

Maintenance & servicing

We keep systems working — whoever installed them

An odour control system only protects you while it's running properly. We provide planned maintenance and rapid-response repair for the systems we install — and, unusually in this sector, for systems installed by others. If your original supplier has disappeared, put prices up or stopped answering the phone, we'll survey the installation and take it on.

Planned maintenance

Scheduled servicing of pumps, lines, nozzles, atomisers and controls — catching wear before it becomes failure.

Emergency repair

Responsive call-out when something stops working, charged by the hour.

System take-over

Free survey of your existing installation — whoever built it — then a proposal to bring it under our care.

Plant hire

Mobile odour and dust units on weekly hire — the fast answer for short-term works or covering a repair.

Orphaned system? Adopt it out to us.
