About us
Our history
Our founder was RAF WW2 Squadron Leader Ronald H Lunney. Having survived the war and a POW camp, Ron identified that food processing would form a vital part of the post war food production revolution.
Through experience and expertise gained in Canada and at home, Ron developed cutting edge solutions to deal with the waste water generated by these new emerging industries.
Disposal of industrial waste water is a growing challenge and for many manufacturers in the food and beverage sector, its disposal is subject to ever more stringent regulation. The financial penalties for getting it wrong are high. It pays to get it right first time.
Puriflo’s best in class solutions overcome these challenges. Built to be compliant with current Water Authority and Environmental Agency requirements, our advanced waste water solutions are completely bespoke. Technologies, plant layout, installation and commissioning are all evaluated on an individual basis by our water treatment consultants. Our commitment to quality and service are second to none.
Puriflo offers a complete end to end solution for both greenfield sites and upgrades and modifications to existing plants. From original testing of effluent and pilot trials to complete plant design and fabrication in our own UK based workshops. This ensures consistency of service at every stage.
Innovative, service and solution-driven, Puriflo has established itself an enviable reputation for delivering superior, best in class water purification systems that meet the needs of the food processing industry.
Building waste water treatment plants for the food industry
Our experience in providing DAF waste water treatment plants for the food processing industry means our customers are able to continue with their core business of supplying the consumer with quality food products, secure in the knowledge that waste waters from their processes are treated to the standards required by the regulatory bodies.
Puriflo ensures the treated waste waters are appropriately managed so they can be discharged safely into the public sewerage system or taken on for further on-site treatment prior to being returned to the environment.
Our engineered bespoke solutions and established proven technologies mean we can cater for all areas of the food processing industry including:
Ready meal producers
Milk processing
Dairies
Cheese manufacturers
Animal skin processors
Breweries
Abattoirs
Poultry processors
How DAF systems work
Trade effluents, generated in the food industry, very often contain relatively large concentrations of fats, oils and greases, referred to as FOG’s. These FOG’s are nearly always in emulsified form because they have been generated during a wash-down cycle where detergents are used.
The DAF process takes a chemical that contains an ion of opposite charge to those maintaining the stability of the emulsion, such as a ferric or an aluminium salt and adds this to the emulsion. The tiny electrostatic force that keeps the emulsion stable is broken and the fats released bond with the ferric or aluminium, along with other impurities.
The result will be visually clear water and tiny, discreet particles of FOG and dirt known as a ‘pin-floc’. This pin-floc can be bound together to form larger particles adding a ‘glue’ known as a polyelectrolyte or poly for short. The resulting larger particles are known as a ‘floc’ because of their appearance.
This resulting ‘floc’ can now be separated from the water using the Dissolved Air Flotation (DAF) process.
The Puriflo DAF System
Puriflo Dissolved Air Flotation plants come in a number of standard sizes. For example with a flotation area of 4.0m by 1.0m, 4.0m by 2.0m, 6.0m by 2.0m etc. They are all packaged units which are piped, wired and tested in the Puriflo workshop prior to delivery to site. They only require a feed pipe, a discharge pipe, a sludge pipe, connection to chemical tanks and a power supply.
Full commissioning and instruction of plant operators is carried out. Operation and maintenance manuals are comprehensive and contain daily and weekly check lists.
Advantages of the Puriflo DAF System
Our innovative design means that there are several advantages to the Puriflo DAF system:
Visibility at all times
Open Topped Reaction Tanks means the whole of the chemical treatment process is visible at all times and if for any reason performance falls off it is immediately obvious to the operator. This is a distinct contrast to competitor waste water systems which use a ‘coil pipe flocculator’ where nothing can be seen. If the chemical process fails for any reason, it is not apparent until 30 or 40 minutes later when the quality of final discharge falls off.
No operator adjustment required
Another key feature of the DAF plant design is that the operator has nothing to adjust. Again competitive systems especially those of the ‘coil pipe flocculator’ type which employ a multiplicity of needle valves to inject white water at various points in the pipe coil are at a disadvantage as they will require some operator intervention.
Fully guarded scrapers
Puriflo’s DAF scraper mechanism is fully guarded and wholly complies with CE and Health and Safety regulations.
Some European equipment, although partially guarded, bears the CE certification but might not fully comply.
Rectangular tanks
Puriflo’s rectangular tanks ensure complete removal of floated sludge unlike some competitor circular tanks where dead spots can form at the centre. Puriflo’s design means full width blades are fitted to the scraper, which travel the full length of the tank, thus there are no dead spots.

Puriflo Technology
Our services
Our team’s long history of expertise in the industrial treatment of waste water ensures that we will always select the most appropriate process to meet strict Water Authority and Environmental Agency requirements.
Technologies and plant layout are always treated as individual to the customer. Installation and commissioning completes the package.
Site investigation
Our first step is always to visit you on site. Our waste water treatment specialist will conduct a full and thorough site survey, free of charge.
This gives us an opportunity to assess your needs and review your current infrastructure. This might include identifying any areas of an existing waste water treatment plant that could form part of a new solution.
Design selection
Once we have a full understanding of your waste water requirements, Puriflo will recommend the most suitable and cost effective process to best deal with your waste water effluent.
Pilot studies
With a DAF pilot plant available to carry out on site trials, we are able to demonstrate the performance, reliability and effectiveness of our technology using “real” factory effluent.
Complete plant design
With over 18 years of British engineering and waste water management expertise, you can be reassured that we will always recommend the most suitable and cost effective waste water treatment design to meet your needs and the appropriate national and international treatment standards.
Service back up
Our service back up means you’ll always have the support of the Puriflo team should you need us.
Once your Puriflo DAF plant is installed and operational, Puriflo offer a full service back up beyond any standard warranty periods.
Upgrading/modification
We always examine and assess existing infrastructure. If we can modify an existing waste water treatment plant to improve its performance sufficiently then we will put forward this recommendation.
This avoids the need to install new or larger equipment offering you a simple, cost effective solution to your effluent problem.
