The FZX sanitary liquid ring self-priming pump provides new capabilities for handling products with entrained air. By using a specially designed impeller and housing the FZX maintains its prime when other pumps become air bound; making it more efficient for complete evacuation of tanks and lines during normal process or CIP.
A water-based washing aid effective in controlling entrained air and surface foam.

These include systems to monitor turbidity, charge demand, pH, temperature, consistency, entrained air, and feed systems; systems to check inventory, take measurements, centre chemical flow, and alert operators when toe system exceeds parameters: and custom extranet sites that can share information across a mill or even between mill sites.
Deaerators prevent accumulation of entrained air while defoamers treat an entrained air problem that already exists.
Select sample locations before and after each additive and test the thick stock, thin stock, and white water streams, looking at such parameters as charge, conductivity, pH, alkalinity, starch residual, turbidity, entrained air, dirt, nits, slime, and biological activity.
Designed for Cleaning-in-Place (CIP) duties containing entrained air, it can also pump product, potentially reducing the capital investment when designing process systems.
The contract stipulated air contents of 4.5 percent to 7.5 percent for the panel mixes, per Precast/Prestressed Concrete Institute guidelines of 6 percent [+ or -]1.5 percent entrained air. Court documents contend some panels were fabricated with mixes measured at air content below 4 percent.
Additionally, the main sources of oil contamination in wind turbines include solid particles, moisture, and entrained air. Consequently, there has been encouraging demand for wind turbine gear oil on the back of the substantial replacement rate of gear oil.
Since this section of the extruder is fully filled, the entrained air cannot move downstream past the melt seal with the molten polymer.
For separation-c=0.3 mm, the ejector presents a relation between the entrained air (m_s) with respect to the primary air (m_p) close to 3 (Table 1).
