Mazzei Solutions for Wineries
Mazzei’s macro aeration wine pump-over Venturi injectors are highly efficient, low cost devices for energizing fermentation. During the macro aeration process, the wine is pumped through a Mazzei® Venturi injector which draws in and uniformly distributes oxygen into the juice. Mazzei’s pump-over process supports yeast development and viability, enhances color and character of the wine, reduces sulfide production and purges excess carbon dioxide from the top of the tank. The Mazzei macro aeration wine pump-over Venturi injector can be used during racking or mixing. In addition, fining agents and other wine additives can be introduced at the suction port of the injector. With the addition of a metering valve, rate at which the liquids are drawn can be controlled.
Washing surfaces with water containing dissolved ozone has been shown to effectively inactivate microorganisms and can be accomplished easily and efficiently with the use of the Mazzei ozone CIP system. Developed as a skid system, it uses the Mazzei GDT™ process in a portable, compact design. High level contamination of barrels can cause wine to be tainted and foul tasting. The solution to this problem… begin with a hot water rinse to clean the barrels; then apply the Mazzei GDT Process which efficiently delivers the disinfecting power of ozone. A cool rinse with ozonated water sanitizes and shrinks the wood pores without the need for excessive rinsing. Sanitizing barrels with ozone extends the life of the barrels without stripping out the oak essence. Mazzei sanitation and CIP systems provide time-tested reliability in high-efficiency ozone mass transfer and off-gas control in a small footprint design. With fewer moving parts and superior technology there is minimal fouling and down time.
Odors caused by septic conditions in wastewater lagoons, ponds, and basins can be reduced or even eliminated by using Mazzei aeration technology. In Mazzei aeration systems, the water is circulated from the bulk liquid through high efficiency Mazzei Venturi injectors which aspirates air or oxygen without the need for blowers or compressors. The resulting air/water mixture is then discharged through Mazzei Mass Transfer Multiplier™ (MTM) Nozzles at high velocity to create a jet of micro-bubbles which continues to transfer oxygen to the wastewater. This high energy mixing assures high oxygen levels which results in odor control. Mazzei aeration systems are all-weather operations that are simple, easy, quiet and economical. In addition, there is no limit on water depth when using the Mazzei aeration process and no temperature loss occurs as does with surface aerators.
Many industries, including wineries, discharge their treated wastewater into public waterways. Current or future permits require minimum dissolved oxygen levels in the discharge water to be 5-7 mg/l. Mazzei offers two solutions to this wastewater problem: the Mazzei aeration system and the Mazzei Pipeline Flash Reactor™ (PFR) for post-treatment.
The Mazzei aeration process is ideal for introducing air or oxygen into wastewater basins, ponds, or lagoons. Treated wastewater is pumped through Mazzei Venturi injector(s) which aspirates either air or concentrated oxygen without the need for blowers and compressors. The resulting wastewater and air/oxygen mixture is then discharged back into the basin through Mazzei MTM mixing nozzles which continues to transfer oxygen to the bulk liquid.
The Mazzei Pipeline Flash Reactor (PFR) provides rapid oxygen transfer within a compact footprint, eliminates noise and high maintenance costs, and is another tool to solve your wastewater problem. Where space is an issue, the PFR eliminates the need for post-treatment cascading systems or diffuser basins required by other technologies. The system utilizes a small sidestream passed through a patented Mazzei Venturi injector to draw in ambient air or concentrated oxygen. The aerated sidestream is then delivered to the PFR where it aggressively mixes with the main flow, uniformly transferring the oxygen in the wastewater pipeline. The PFR can also be utilized for the dissolution of oxygen gas in systems with high dissolved oxygen requirements. PFRs are custom designed to each client’s application and performance requirements.
