High Efficiency Air Flotation Machine Food Factory Sewage Treatment Equipment Quick Installation

The high-efficiency air flotation machine is a professional and customized sewage treatment equipment specially developed for food processing factories. It is perfectly applicable to wastewater generated from food production, slaughtering and processing, beverage manufacturing, pastry processing, and catering processing. This equipment effectively solves the common pollution problems of food factory sewage such as high oil content, high suspended solids (SS), high organic matter and residual fine fiber impurities. With integrated design, stable operation and excellent purification performance, it has become the core pretreatment and secondary purification equipment for food industry sewage treatment projects.

Adopting advanced micro-bubble flotation separation technology, the equipment realizes rapid adhesion and floating separation of oil stains, suspended particles and colloidal substances in sewage. It features high treatment efficiency, small floor space, low operating cost and no blockage risk, fully meeting the environmental discharge standards and factory water recycling requirements of food production enterprises.

This air flotation machine adopts optimized dissolved air cavitation flotation technology. Through the professional air-water mixing system, a large number of uniform and fine micro-bubbles are generated in the water body. After coagulation and flocculation treatment by PAC/PAM dosing system, fine suspended solids, animal and vegetable grease, protein colloids and organic debris in food wastewater will adhere to the micro-bubbles. Relying on the buoyancy of bubbles, the impurity flocs quickly float to the water surface to form dense scum.

The automatic anti-corrosion slag scraping system continuously cleans the surface scum and discharges it into the sludge collection tank, while the purified clean water is stably discharged from the water outlet at the bottom of the equipment. The whole separation process is efficient and continuous, with short hydraulic retention time and no secondary precipitation pollution.

• Targeted Treatment for Food Wastewater: Specially designed for high grease, high SS and high organic sewage in food factories, with a grease removal rate of over 95% and suspended solids removal rate of 90%-99%, which can effectively reduce subsequent biochemical treatment pressure.
• High Efficiency & Energy Saving: Optimized internal flow channel structure reduces water flow turbulence and energy loss. Compared with traditional sewage treatment equipment, it saves 30%-50% of operating power consumption, with low ton-water treatment cost, suitable for long-term continuous operation of food factories.
• Zero Blockage & Stable Operation: The improved micro-bubble generation structure avoids blockage caused by food residues, fibers and grease impurities. The whole equipment operates stably without frequent maintenance, adapting to 24-hour uninterrupted production and sewage discharge of food enterprises.
• Compact & Easy Installation: Integrated skid-mounted overall structure, small floor space, no complicated civil engineering requirements. It can be quickly installed and put into use, greatly shortening the project construction cycle.
• Automatic Intelligent Operation: Equipped with full-automatic dosing, water level adjustment and slag scraping control system. It realizes unmanned automatic operation, simple operation and low labor cost, which is in line with the intelligent production management mode of modern food factories.
• Durable & Sanitary: The main body is made of anti-corrosion carbon steel or stainless steel, with acid and alkali resistance, rust resistance and easy cleaning. It avoids bacterial growth and dirt accumulation, meeting the hygienic operation requirements of food production workshops.

Widely used in sewage treatment and water quality upgrading of various food processing enterprises, including:

• Slaughtering and meat processing factories (animal oil, blood water, meat residue wastewater)
• Beverage and dairy processing factories (protein, sugar, suspended colloid wastewater)
• Snack and pastry processing factories (grease, flour residue wastewater)
• Catering central kitchen and food factory canteen wastewater
• Aquatic product processing and vegetable processing factory wastewater

• Continuous and efficient solid-liquid and oil-water separation
• Short hydraulic retention time, fast water treatment speed
• Low sludge moisture content, convenient subsequent sludge dewatering and disposal
• Support customized treatment capacity (5-500m³/h) and equipment size
• Meet national and international industrial sewage discharge standards

As special environmental protection equipment for food factory sewage treatment, the high-efficiency air flotation machine solves the industry  points of difficult grease removal, easy equipment blockage and high operating cost in food wastewater treatment. With high purification efficiency, stable performance and low maintenance cost, it is the preferred pretreatment and advanced treatment equipment for food industry sewage treatment projects, helping enterprises realize standard sewage discharge and water resource recycling.
