High-rate clarification that floats out suspended solids, fats, oils and grease with a blanket of micro-bubbles — fast, and in a compact footprint.
DAF removes the light, hard-to-settle solids that gravity clarifiers struggle with — lifting flocs, oils and fibres to the surface for skimming. CWG has built high-rate DAF and Turbo-DAF units for textile, food and beverage plants across Pakistan, handling flows from a few to hundreds of cubic metres an hour.
Dissolved Air Flotation dissolves air into water under pressure, then releases it into the effluent as a cloud of micro-bubbles that attach to coagulated solids and float them to the surface.
The floated sludge is skimmed off the top while clarified water is drawn from below — achieving high solids and FOG removal in a small, high-rate tank.
With coagulation and flocculation ahead of it, DAF handles the low-density solids, colour and emulsified oils typical of textile and food-industry effluent.
Chemically conditioned effluent meets a stream of micro-bubbles that carry contaminants to the surface for removal.
Coagulant and polymer bind fine solids, oils and colour into larger, floatable flocs.
A portion of clarified water is saturated with air under pressure in a saturation vessel.
Released micro-bubbles attach to the flocs and float them into a surface blanket.
The float is skimmed to sludge handling while clear water is drawn from the base.
Treats large flows in a compact tank — minutes of retention, not hours.
Floats out fats, oils and grease that gravity settling leaves behind.
Ideal for low-density textile and food solids that won’t settle.
High surface loading means a plant that fits where space is tight.
Surface float is drier than settled sludge, easing dewatering.
A workhorse pre-treatment for CWG’s biggest industrial clients.
Removes light solids and FOG that simply won’t settle — in a fraction of the footprint.
Handles high solids and oily loads that would quickly blind a media filter.
Coagulation plus micro-bubbles capture emulsified oils basic skimmers miss.
Pakistan’s textile, denim and food industries produce high-colour, oily, hard-to-settle effluent. High-rate DAF is often the most effective, space-efficient first stage — protecting downstream biology and helping plants meet NEQS limits.
Since 1998, CWG Watch Water Technology has delivered advanced water & wastewater solutions across Pakistan — wastewater plants, RO, demineralization, softening, filtration, specialty chemicals and complete plant engineering. With decades of experience, international technology partnerships and a proven portfolio, we design customised water and wastewater treatment solutions built specifically for Pakistan’s industrial requirements.
Send us your effluent characteristics and flow, and CWG will size a DAF or Turbo-DAF clarifier to suit.
