Clarifying Liquid Filtration

  There are various reasons that make filtering necessary in processes. The raw materials might have impurities that require removal at the start of the process. After the initial mixing to produce the process slurry, the mother liquor could have…

This vacuum filter has a swing-out base and side discharge

The Simplefilter consists of a heated insulated vessel, with a filtration media that is attached to a heated swing-out base and a side-discharge hatch. The design makes drying efficient and removal of the product less complicated. High containment discharge is…

This dryer also performs other unit operations

The Boono Paddle Dryer is an indirect dryer that can also be used for crystallization, coating, sterilization and calcinations. The wide range of applications makes it suitable for use in the food, pharmaceutical and fine-chemicals industries. The large surface area…

Recover precious-metal catalysts with this depth filter

The new depth filter medium, BecoPad recovers precious metal catalysts from reaction products without losses, so they can be returned to the process. Because very fine catalyst components are also removed, the very high purity of the mineral-free BecoPad and…

A less complicated filtration system

As an alternative to more complex and expensive technologies, the simplefilter is designed for many applications, such as hydrogenation, carbon filtration, catalyst recovery, prefilter for microfiltration and for filtration of APIs (active pharmaceutical ingredients) and intermediates. The simplefilter consists of…

Reduce Costs with ‘Step-down’ Filtration

Among the challenges of effective solid-liquid filtration is the accumulation of solids on the filter surface, which creates an increasingly dense mass that process fluid must push through. In many applications in the chemical process industries (CPI), a step-down filtration…

This agitator design improves performance of Nutsche filtration

Good agitated Nutsche filter dryer performance relies heavily on the agitator design. The design of this companys agitator has a series of sharp curved blades with spaces at different centers of each arm. When moving or lifting filter cake product…

This cake dryer has a unique heat-transfer system

The CakeStand Tray Dryer uses a unique heat-transfer system that ensures uniformity across all heating plates. The ergonomically designed unit has features, such as a pivoting door, front and back access, and heating plates that hang from the roof, that…
