Combination filtration of pressure, vacuum and clarification technologies for optimum process solutions

PharmaChem

Filtration experts, over the years, have discussed combination filtration and debated its definition. In the realm of cartridge filtration, simply defined, a combination filter is one that does at least one other processing job at the same time as filtering a suspension. For example, this could be carbon canister which removes both suspended and dissolved components. In water applications, a combination filter removes bacteria, sediment, chlorine taste and odor, and scale. In lubrication oil filtration, combination filtration refers to full-flow and by-pass flow filtration. Finally, for small scale process filtration, combination filtration is installing bag and cartridge filtration systems in series.

There is, however, a new definition of combination filtration that transcends the standard approach and will assist process engineers with trouble shooting and “idea-generation.” The approach relies upon the slurry analysis and testing to uncover the “process symptom” and then develop a process solution called “combination mechanical slurry conditioning and filtration.” This article discusses slurry testing and process analysis and then illustrates seven case history example installations showing “combination mechanical slurry conditioning and filtration” including data in Appendix A.

bauma 2013: Gravel Processing with BHS Rotor Centrifugal Crushers

bulk solids handling

At bauma 2013, BHS-Sonthofen will showcase the rotor centrifugal crushers of the RSMX series for processing hard and medium-hard rock to produce aggregate chippings and high-quality aggregates. The “rock-on-rock” principle and the patented rotor with just two centrifugal chambers offer considerable advantages over multi-chamber rotors in everyday practice.

CPM prestress deploys new BHS twin shaft

Concrete Products (USA)

Centrat Pre-Mix Prestress Generat Manager Chuck Prossack recenUy christened one of the key components of the company's Spokane, Wash., operation: a BHS DKX 3.0 Batch Mixer, with 4-yd. capacity. The otd equipment was prone to breakdowns and high repair costs, aggravated by the potential for recurring shaft damage.

Twin-shaft batch mixers are becoming accepted in precast plants

CPI - Concrete Plant International

At the bauma 2013 BHS-Sonthofen will be exhibiting the mixers from the DKX series, which can be adapted to the needs of the precast industry with an extensive construction kit system. They are equally suitable for mixing fibre-reinforced and dyed concretes as well as self-compacting concretes, HPC and UHPC. They ensure high homogeneity and reproducibility of different recipes with short mixing times.

Recycling of refrigeration units: Cost reduction by 65%

recovery

BHS has developed a complete solution for the economical recycling of refrigeration units, combining mechanical crushing of the units with thermal-catalytic oxidation of the refrigerants and blowing agents. The only end products of the process are the shredded so Iids and carbon dioxide, as weil as a saline solution. The BHS method renders superfluous several steps required by other methods, which cuts the costs of processing considerably.
