We offer a wide range of rental lab filters and pilot filters for on-site testing. In this way, you can confirm and expand on findings from preliminary tests on a semi-industrial scale. We supply state-of-the-art laboratory and pilot filters or pilot filtration systems for all BHS filter systems. Each of these testing machines is equipped for a specific application and designed for rental applications to closely simulate production. Our qualified service technicians provide on-site training and support. The results of these tests ensure that the planned scale-up production system is properly designed.

We not only provide laboratory or pilot filter systems for testing purposes, but we also sell these units both new and used for low-volume production scenarios or for use at your own technical center.

Thin-cake filtration technology to meet full containment for air-sensitive and toxic chemical and pharmaceutical production

In many chemical and pharmaceutical processes, solid-liquid separation, cake washing and drying steps directly impact the effectiveness of the production operation. Further complicating these operations is the nature of the process and especially if the process is air-sensitive or toxic. This article discusses the choice of thin-cake (2-25 mm) pressure separation technology for full containment, no residual heel and their benefits to optimizing the effectiveness of the production process. For full containment, the paper then continues with a discussion of clean-in-place operations to meet current Good Manufacturing Practices (cGMP) guidelines including riboflavin test, validations and ANSI/ISA S88 and IEC 61512-1 batch process control systems.

Choosing a Fine-Particle Filtration System

Filtration technology has advanced to meet the demand to remove small particles at low concentrations. When designed ocrrectly, a candle filter or a pressure plate filter may be a more-efficient replacement for a traditional filtration scheme.

Thinking like Sherlock Holmes for process filtration technology selection

Sherlock Holmes and Dr John Watson are fictional characters of Sir Arthur Conan Doyle. Process engineers who live in the real world can learn many things from the two of them for solving process filtration problems. This article will intertwine the detective techniques (mindfulness, astute observation, logical deduction and others) of Holmes and Watson with the problem-solving skills required to select process filtration systems.
