Compact Automatic DAF Machine for Oily Wastewater Treatment

In the glow of a busy plant, where oily water once pooled like a murky pond, a compact automatic DAF machine stands like a quiet lighthouse—sleek, confident, and ready. With a soft hum and a ballet of microbubbles it lifts oil and suspended solids to the surface, leaving downstream water crystal-clear and the floor of operations brighter. Small in footprint but powerful in performance, it offers hands-free operation, energy-smart efficiency, and instant reliability that saves space, time, and cost.

Compact Automatic Modular Efficient

Our compact automatic Dissolved Air Flotation system delivers fast, reliable separation of oil, grease and suspended solids so you get clearer effluent, lower disposal costs, and minimal operator intervention. Skid-mounted, space-saving shape with a stainless-steel bulk-air impeller, robust electric cabinet, maintenance-free aerator and simple industrial style ensure durable quality, easy installation and secure export-carton packing. Available in multiple flow models with short lead times and low operating cost, it’s ideal for petrochemical, oilfield, food and pulp industries that need efficient oily wastewater treatment and hassle-free upkeep.

Compact Automatic Oil Separation

This compact automatic DAF machine uses Dissolved Air Flotation with a high-speed cavitation aerator and stainless-steel bulk air impeller to generate 30–100 µm microbubbles that attach to grease, jelly and suspended solids, lifting them to the surface for skimming without the need for a circulating pump, air compressor or pressure vessel. Its simple, robust structure and integrated electric cabinet deliver maintenance-free, space- and energy-saving operation across multiple capacity models (1–500 m3/h), offering low investment and reduced operating cost for oily wastewater treatment in petrochemical, oil production, food and paper industries. Automated controls and continuous skimming provide rapid solid–liquid separation and clarified effluent suitable for reinjection or downstream processes, minimizing operator intervention while maximizing treatment efficiency.

Compact Automatic DAF System

This compact automatic DAF machine uses Dissolved Air Flotation (CAF cavitation air flotation) technology to efficiently separate grease, oil and suspended solids from industrial and municipal wastewater. The self-contained design eliminates the need for circulating pumps, air compressors and pressure vessels, cutting footprint and operating costs while providing simple, maintenance-free operation. Microbubbles generated by a high-speed impeller attach to flocculated solids and lift them to the surface for skimming, and modular models cover flows from 1 to 500 m3/h for oily wastewater treatment in petrochemical, oilfield and food-processing applications.

◎ Low Cost Operation

◎ High Efficiency Separation

Compact Automated Efficient Reliable

Built from a decade of industrial wastewater research and brand engineering excellence, the Compact Automatic DAF Machine for Oily Wastewater Treatment pairs a rugged modular stainless-steel frame with patented micro-bubble generation for dependable, low-footprint operation. Leveraging Dissolved Air Flotation with automated PLC control and intelligent dosing, it efficiently removes free and emulsified oil, suspended solids and turbidity while enabling fast start-up, self-clean cycles and low energy consumption. Key features—compact plug-and-play skid, adjustable air saturation, integrated sludge dewatering and remote monitoring—translate into advantages of reduced operating costs, minimal maintenance, higher treatment recovery and consistent compliance with discharge standards.

Material introduction

Built for oily wastewater treatment, the Compact Automatic DAF Machine employs corrosion‑resistant stainless steel (SUS304/SUS316) for the flotation tank, bulk air impeller and wetted fittings, while the structural frame uses carbon steel with epoxy anti‑corrosion coating for long service life. Skimmer blades and other non‑metallic parts are molded from wear‑resistant plastics (HDPE/PP) and the perforated stainless impeller produces 30–100 μm bubbles to optimize Dissolved Air Flotation performance. Industrial‑grade motors, sealed bearings and an IP‑rated electric cabinet protect controls from oil and moisture, minimizing maintenance in continuous operation.

FAQ

What is a Compact Automatic DAF Machine used for and which types of oily wastewater can it treat?

A Compact Automatic DAF (Dissolved Air Flotation) Machine is used to separate and remove free and dispersed oil, grease, suspended solids and light organic matter from wastewater by generating fine air bubbles that float contaminants to the surface for skimming. Typical feed streams include refinery and petrochemical oily water, produced/bilge water from ships, metalworking coolant and emulsions, automotive wash water, food-processing oils, stormwater with hydrocarbons, and pretreated wastewater prior to biological or membrane systems.

What level of treatment performance can I expect and what effluent quality is achievable?

Removal performance depends on influent characteristics and process tuning, but compact DAF systems commonly achieve high removal of free oil (>90–99% for free-phase oil) and substantial reductions in TSS and emulsified oil. With appropriate chemical dosing (coagulants/flocculants) and correct operation, effluent can meet many industrial discharge limits or downstream process requirements; exact results depend on oil type, oil concentration, pH, and solids load.

How is the unit installed and what does “compact” and “automatic” mean in practice?

Compact means a small footprint and skid- or container-mounted design for easy siting in limited spaces; many models are plug-and-play requiring minimal civil work. Automatic refers to integrated PLC controls, automated air saturation, dosing pumps, float skimmer control and alarms so the unit runs with limited operator intervention—typically requiring only routine monitoring and periodic maintenance.

Can the DAF machine integrate into existing treatment lines, and where in the process is it best placed?

Yes — compact automatic DAF units are commonly installed as primary treatment to protect downstream biological or membrane systems, as a polishing step after primary clarification, or as a standalone treatment for oily streams. They can be connected upstream or downstream of equalization, chemical dosing, or oil/water separators and are often used as a retrofit where space is constrained.

How is sludge handled and what are the typical maintenance needs?

Float (skimmings) is removed by an automatic scraper or pump and discharged to a sludge collection point; the sludge volume and concentration vary with feed but can be further dewatered by filter press or centrifuge if needed. Routine maintenance includes daily checks of pumps, air saturation and dosing systems, weekly inspection/cleaning of nozzles and skimmers, and periodic calibration of sensors and PLC alarms. Annual service typically covers air compressor maintenance and thorough inspection of mechanical parts.

What operational issues should I watch for and how are common problems resolved?

Common issues include poor flotation (insufficient bubble generation), oil carryover, excessive foam or quick sludge build-up. Troubleshooting steps include checking air saturation pressure and recycle flow, verifying coagulant/flocculant type and dosing rate, confirming pH and temperature are in target ranges, and inspecting skimmer operation. The integrated control system usually provides alarms and logs to help diagnose issues quickly; regular sampling during startup and after changes helps optimize performance.
