Design of Experiments (DoE):How to Handle Hard-to-Change Factors Using a Split Plot

This methodology facilitates multifactor testing. However, it comes at a price: a loss in power for detecting effects The traditional approach to experimentation — often referred to as the “scientific method” — requires changing only one factor at a time…

OSHA launches challenge for hearing protection

The U.S. Department of Labor's Occupational Safety and Health Administration (OSHA) and Mine Safety and Health Administration, in partnership with the National Institute for Occupational Safety and Health (NIOSH), have initiated a "Hear and Now – Noise Safety Challenge." According…

Save energy with passive aeration wastewater treatment

This company’s flat-sheet Membrane Aerated Biofilm Reactors (MABR; photo) provide high-effluent wastewater-treatment solutions with 90% less energy and 50% less sludge, according to the manufacturer. The MABR is a spirally wound air sleeve submerged in a tank, to which wastewater…

This mechanical discharge system is very flexible

The ADM type Kokeisl mechanical discharge and dosing module is used for discharging bulk material in any amount desired from silos, containers and other vessels. From a few grams to several tons of material, discharge is realized accurately according to…

Automated sample handling for particle analysis data

The FlowCam ALH automated liquid-handling system (photo) automatically processes up to 96 samples per run without requiring human involvement or supervision. This eliminates the potential for human error in sample handling and pipetting, and ensures that data are accurate. Ideal…

This PLC securely integrates devices from multiple vendors

The recently launched ControlEdge programmable logic controller (PLC; photo), when combined with this company’s Experion Process Knowledge System, provides secure connectivity and tight integration to instruments, equipment and software from multiple vendors. ControlEdge is said to be the first PLC…

A valve manifold with zoned safety capabilities

The Numatics 503 Series valve manifold (photo) enables end users to configure up to three safety circuits in a production machine. The manifold can create up to three independent electro-pneumatic safety zones, while also allowing independent non-safe sections to coexist…

Stainless-steel local control stations can be designed online

After this company created the possibility to design GRP (glass-reinforced polymer) control stations for use in hazardous areas, it has now made this possible with stainless-steel local control stations with up to 15 modules (photo). The selection and placement follows…

This segment coupler provides speed on Profibus DP

With the basic segment coupler (photo) — the successor to SK1 and SK2 — Profibus PA nodes appear as DP nodes in the distributed control system (DCS) and can be configured and diagnosed without additional tools. The basic segment coupler…

New wirelessly monitored storage-tank emergency vents

The new wirelessly monitored Enardo 2000 emergency pressure-relief vents (EPRVs; photo) provide safety control by managing abnormally high storage-tank pressures in the oil-and-gas, chemical, petrochemical and pharmaceutical industries. Under normal operating conditions, an EPRV remains closed. The immediate knowledge of…
