Compact Efficient Durable Performance

Treat oily wastewater efficiently with an 80 m3/h Dissolved Air Flotation system that cuts operating costs and footprint by removing the need for circulating pumps, compressors and pressure vessels. Its compact rectangular tank, stainless steel bulk-air impeller and modular, maintenance-free style guarantee consistent micro-bubble generation, high-quality solids separation and simple operation. Delivered in standard export carton packaging for quick shipping, the durable, space-saving design enables easy installation, minimal upkeep and long service life across petrochemical, food and paper industries.

Compact Low-Maintenance Oil Clarifier

The 80 m3/h Dissolved Air Flotation (DAF) system is a compact, low-footprint unit built around a cavitation aerator, flotation tank, skimmer and electric control cabinet with a stainless-steel bulk-air impeller that generates 30–100 µm microbubbles. It performs efficient solid–liquid separation of grease, jelly and suspended solids in oily wastewater without a circulating pump, air compressor or pressure vessel, reducing energy use, operating cost and maintenance. Suited to petrochemical, oilfield, food and paper applications, the design enables simple installation, reliable skimming of concentrated scum and lower capital and lifecycle expenses.

Compact Low-Maintenance Oily-Water DAF

The 80 m3/h Dissolved Air Flotation system delivers compact, low‑maintenance solid–liquid separation for oily wastewater by using a cavitation air flotation (CAF) aerator to generate 30–100 µm microbubbles via a bulk gas impeller. Without circulating pumps, air compressors or pressure vessels, the design saves space and operating costs while efficiently removing grease, suspended solids and colloids. Stainless steel aerator, flotation tank and skimmer provide simple operation and economical, easy-to-maintain performance for petrochemical, oilfield, dairy and meatpacking effluents.

Efficient, Compact, Low Maintenance

Developed by a team with decades of wastewater-treatment experience, the 80 m3/h DAF System embodies a brand commitment to durable, field-proven solutions for oily water challenges. Using Dissolved Air Flotation, the compact, skid-mounted unit delivers reliable oil and suspended solids removal at up to 80 m3/h while minimizing footprint and simplifying operator workflows. Key advantages include low-maintenance operation with automated controls and self-cleaning skimming, energy-efficient aeration, corrosion-resistant construction, and easy access for service—reducing lifecycle costs and enabling fast startup on site.

Material introduction

The 80 m3/h Dissolved Air Flotation system is constructed with a corrosion-resistant stainless steel bulk air impeller and robust tank materials to withstand oily wastewater environments. Skimmers and aeration components employ wear-resistant polymers or coated steels while the control cabinet is housed in a weatherproof, corrosion-protected enclosure for dependable, low-maintenance operation. These material choices reduce fouling and chemical attack, keeping the compact unit efficient and durable for continuous oily water treatment.

FAQ

What is the 80 m3/h DAF System and in which application scenarios is it typically used?

The 80 m3/h DAF (dissolved air flotation) system is a compact, skid-mounted unit designed to treat oily water at a nominal rate of 80 cubic meters per hour. Typical applications include bilge and oily water treatment on offshore vessels and platforms, refinery and terminal wastewater polishing, metalworking and machining coolant recovery, automotive service and maintenance shop effluent, food-processing (fats and oils) wastewater, and as a pre-treatment step before biological treatment or reverse osmosis.

What kinds of oil contamination and solids can the system handle?

The unit is effective for free and dispersed oil, light emulsions (with appropriate dosing), suspended solids and floatable materials (grease, sludges). Very stable emulsions, extremely fine dissolved hydrocarbons, or very high solid loads may require stronger chemical coagulants, upstream coalescing units, or additional pretreatment (e.g., oil skimmers, screens, or dissolved air flotation with enhanced chemical dosing).

What treatment performance and effluent quality can I expect?

Under typical conditions with correct chemical dosing and operating practice, the 80 m3/h DAF can remove the majority of free and dispersed oil and significantly reduce TSS and FOG. Operators commonly achieve single-digit to low-double-digit mg/L oil-in-water results for moderate loads; final effluent quality will depend on influent characteristics, pretreatment, and dosing — compliance with specific discharge limits should be validated by site testing.

What pre-treatment, chemicals, and operating parameters are required for normal operation?

Routine pre-treatment may include coarse screening, grit removal or oil skimming for heavy free oil. The DAF will usually require a coagulant and/or flocculant and pH adjustment to destabilize emulsions and aggregate solids. Key operating parameters include stable flow near 80 m3/h (it tolerates some variation), correct chemical dosing, and routine control of air saturation and skimming settings. Startup commissioning and on-site tuning of chemicals are recommended to optimize performance.

How compact and low-maintenance is the system? What are the maintenance needs?

The system is designed to be compact and plug-and-play — skid-mounted with integrated pumps, air saturation, flotation tank and skimmer — minimizing civil works. Maintenance is relatively low: daily visual checks and sludge/float removal as needed, weekly inspection of pumps and dosing systems, monthly verification/calibration of chemical feed and controls, and an annual inspection/service of mechanical and pneumatic components. Consumables are mainly coagulants/flocculants and routine spare parts for pumps and valves.

What limitations or conditions would make the 80 m3/h DAF system unsuitable, and when should I consider alternatives?

The DAF is less effective on very stable oil-in-water emulsions without substantial chemical treatment, dissolved-phase hydrocarbons, extremely high TSS concentrations, or when final ultralow oil targets (e.g., <1 mg/L) are mandatory without a polishing step. In those cases consider upstream coalescers, membrane filtration, advanced oxidation, or biological polishing after DAF. Also consider site-specific factors such as hazardous-area classification, very low temperatures, or space constraints that may affect installation or safe operation.
