Open-Tank Mechanical Foam Breaker

In large-scale industrial processing, wastewater treatment, and open chemical blending, severe surface foaming creates massive operational risks. Traditional chemical anti-foam consumables generate downstream fouling, coat expensive filtration membranes, and present environmental compliance hazards. The BODF-II Series Open-Tank Mechanical Foam Breaker introduces a sustainable, heavy-duty engineering barrier, delivering high-capacity, chemical-free surface foam suppression optimized for non-pressurized tanks and open reservoirs.

Product Overview
The BODF-II Series Open-Tank Mechanical Foam Breaker is a versatile industrial deaerator engineered for unpressurized vessels and wide-area pools. Deployed via straightforward top-mounted, suspended, or cantilevered installation, this robust machine intercepts and shatters dense foam layers using pure mechanical energy.

By eliminating chemical anti-foam consumables, the BODF-II protects sensitive downstream equipment from chemical residue buildup. When integrated with an auxiliary exhaust condensation system, it dramatically cuts raw material spillage and overflow hazards, keeping industrial production clean and cost-effective.

Detailed Analysis of Working Principle
The BODF-II employs an open-capture dynamic cycle designed to process massive volumes of foam continuously without manual intervention:
Foam Capture: As the process fluid generates surface foam, the expanding layer rises and is drawn directly into the high-velocity rotor work zone via the pressure differential created by the dynamic blades.
Mechanical Shearing: Precision-engineered dynamic rotor blades rotate at optimal velocities, executing intense mechanical shear forces that immediately shatter the resilient bubble wall structures upon contact.
Porous Wall Filtration: Driven by powerful centrifugal force, the shattered, gas-free fluid is propelled outward, passing through a specialized porous wall structure into an outer scroll-style collector housing.
Pipeline Return: The compressed liquid within the scroll collector is channeled directly into external return pipelines. From there, it is gravity-fed or pumped back into the open reservoir, maintaining a complete, waste-free liquid recycling loop.

Key Features
Sustainable & Eco-Friendly Operation: Completely avoids dependency on expensive chemical anti-foam formulations, protecting downstream membrane bioreactors (MBR) and sensitive filtration systems from fouling.
Zero Basin Overflow & Spillage: Suppresses aggressive, sudden foaming on the spot, eliminating plant safety hazards, valuable product spillage, and potential environmental compliance penalties.
Preserved Material Purity: Prevents the buildup of unwanted chemical surfactant residues within the process fluid, guaranteeing the raw chemical purity of your liquids and stabilizing ongoing biochemical reactions.
Maximized Process Yield: Returns trapped active microorganisms or valuable food ingredients from the foam back into the fluid media rapidly, preventing dry-outs and driving up overall plant extraction rates.
Rugged & Adaptable Installation: Requires absolutely no tank pressure modifications. The unit can be easily mounted on structural steel beams, suspended over wide aeration basins, or clamped directly to open tank rims.

Target Applications
Industrial Chemical Blending: Highly effective for daily chemical formulation, surfactant manufacturing, cosmetics blending, and liquid detergent mixing.
Food Processing & Formulation: Widely adopted in industrial fruit juice mixing, industrial sauce blending, beverage formulation, and open fermentation tuns.
Environmental Engineering: A critical component for municipal wastewater aeration basins, industrial effluent treatment pools, and open industrial reservoirs.
