Trity Environ Solutions is a trusted DAF system manufacturer in India, engineering micro-bubble flotation systems that separate oil, grease, and suspended solids from wastewater faster than gravity clarifiers. Our DAF units are built for Indian industrial conditions, ISO 9001:2015 certified, with pan India installation support.
High oil and grease levels, rising BOD or TSS in treated effluent, and repeated pollution control board notices usually point to the same root cause: a missing or underperforming primary separation stage. A dissolved air flotation (DAF) system uses microscopic 20 to 80 micron air bubbles that attach to suspended particles and oil droplets, floating them to the surface for continuous skimming, rather than relying on gravity settling alone. This makes DAF significantly faster and more effective than a conventional clarifier at handling emulsified oils and light biological floc before they ever reach your industrial effluent treatment system or downstream systems.
For applications where free floating oil dominates rather than emulsified oil, a mechanical skimming unit can be a simpler, lower cost alternative, and Trity Environ Solutions manufactures both technologies to recommend based on your actual oil profile rather than defaulting to one option.

A DAF unit that isn't matched to properly dosed coagulant and polymer upstream will underperform regardless of how well the tank and saturator are built, since destabilizing particles before they reach the flotation zone is what makes bubble attachment effective. Trity Environ Solutions runs jar testing on your actual effluent during the design phase to determine optimal dosing, rather than assuming a generic chemical program will work across every feed.
A DAF unit sized off a generic capacity chart, without accounting for your actual flow rate, TSS, FOG, and temperature, often underperforms even when built to a high standard. Trity Environ Solutions backs every installation with application-specific sizing, operator training, and an Annual Maintenance Contract, so performance holds up under real operating conditions.
Once float sludge is collected, it still needs dewatering, and Trity Environ Solutions manufactures filter press systems and decanter centrifuges to handle that next stage, so your primary and secondary sludge handling come from one accountable supplier.
Food and beverage processing, edible oil refining, and dairy plants generate high-FOG effluent where DAF is the industry-standard primary stage, while paper mills and textile dyeing units rely on it for fibre and dye solids recovery. Municipal facilities also use DAF as a primary clarifier replacement in sewage treatment plants handling high-solids inlet streams, and our units integrate seamlessly with downstream systems including our commercial RO plants wherever treated water needs to support further purification or reuse.
Uses uniform 20 to 80 micron bubbles generated through a pressurised saturator, offering the most precise and consistent flotation control for demanding applications.
Generates bubbles by drawing air directly into the flow stream through a mechanical disperser, a simpler configuration suited to less demanding separation needs.
Rectangular tank design fits linear plant layouts efficiently, offering straightforward integration with existing equalization and clarification infrastructure on constrained sites.
Circular tank design suits sites requiring uniform flow distribution and simplified skimmer mechanics, often preferred for larger capacity installations.
A conventional clarifier relies on gravity to settle heavier particles, while a DAF system uses pressurised micro-bubbles to float light-density contaminants like emulsified oils and fine floc to the surface, achieving faster, more effective separation.
Yes, DAF units can typically be added as a primary treatment stage upstream of biological treatment in an existing plant, after assessing current layout, hydraulics, and inlet characteristics.
Dosing requirements depend on effluent type, but typically involve a coagulant such as alum or ferric chloride along with a polymer flocculant, with optimal dosing confirmed through jar testing.
Float sludge is sent to a holding tank for further thickening or dewatering, and since it is significantly drier than gravity sludge, it is generally easier and cheaper to handle.
Routine maintenance includes cleaning skimmer blades, inspecting saturation nozzles for scaling, checking recycle pump performance, and periodic lubrication of drive components.
A standard skid-mounted unit typically installs and commissions within 5 to 10 working days, while larger systems with integrated dosing and automation may take 2 to 4 weeks.
