Dissolved Air Flotation Unit

Like the Model 6, our DAF Model 10 is a complete skid mounted treatment system. This model can treat up to 20,000 litres of wastewater per hour.

WMP Model 10 DAF unit delivery


Like all of our DAF models, we are able to transport our systems from our site to yours. All of our DAF units are delivered on a HIAB and come complete with other peripheral equipment. These include feed pumps, a magnetic flow meter and level sensors to name a few.

Take a look at this recent installation we fulfilled for one of our clients:


The Model 10 is a perfect middle point for those in need of a medial flow rate. It combines the compact nature of the Model 6 with the output more similar to the Model 20.

Similarly to our other DAF models, the Model 10 utilises level sensors or float switches to automate the wastewater treatment process.

Once the pre-set sensor signals the feed pump, the system draws effluent directly into the on-board mixing vessels. This is where chemical treatment, pH correction and flocculation occurs. The treated effluent then passes into the Dissolved Air Flotation cell where the automated air dissolving vessel (our own robust super saturator unit) introduces highly air saturated water. The saturated water then floats the flocculated waste up to the surface for removal by a chain driven scraper blade.

To ensure the remaining water is free from solids, it is fed under a baffle and then over a weir plate for final discharge or even further treatment.



Speak to a member of the Watermark Projects team. Discuss your current requirements, any future projects you might be planning or even to get advice on consent breaches, billing or planning.


With every new customer we think the best first step is a site visit from one of our project engineers. This allows us to meet you face-to-face and start a good working relationship, get a feel for the site itself and take a sample of your wastewater for analysis.


Every site is different. The wastewater is different, the consent is different and therefore the solution will be different. This is why we'll undertake a lab analysis of your wastewater to identify the most effective treatment solution for your waste.

This analysis also allows us to determine achievable removal rates with contaminants such as COD, TSS and FOG as well as pH correction.


Thanks to the previous key steps, we're now in a position to provide a proposal to for a suitable, cost effective and efficient solution for your site. Proposals can range from a complete new system through to modifications to the existing plant for optimisation.

While we manufacture the vast majority of our systems in-house, proposals can also include 3rd party supplied parts such as the balance & sludge holding tanks as well as potential tertiary systems.
