Work in Wisconsin demonstrates viability of waste-to-energy projects

Many states have programs; use reduces cost and liability
High-strength wastes — characterized by elevated levels of organics in wastewater as measured by biological oxygen demand, total suspended solids and oil & grease — are increasingly difficult and costly to manage.

How to turn eggshell waste into income

Drying system reduces pathogen risk; residue used as fertilizer or animal-feed mineral additive
Each year, an estimated 76 billion eggs are consumed in the United States. Prior to final consumption, about 25 billion of those eggs are first processed into egg products. The egg-processing plants must break those eggs before further processing occurs. In doing so, these plants generate an estimated 600,000 tons of eggshell waste per year.

Thermal desorption technology gains ground as remediation solution

Indirect heating of feed material in oxygen-deficient environment separates organic constituents from waste material
Indirect thermal desorption can efficiently remediate soils and waters, and recover otherwise hazardous hydrocarbons — without venting harmful volatile organic compounds (VOCs) into the atmosphere.

A steel storage tank’s coating is only as good as its application

In factory or field, preparation, application and curing governed by quality control tests
The most carefully considered decision made when buying a steel storage tank should be the one that determines the quality of its coating. Other factors — including size, capacity, cost, turnaround time and ease of construction — are impacted by the coating decision.

PVDF delivers answers in challenging membranes market

Use grows in hollow fiber membranes for process-industry water treatment
Since its introduction in 1964 by Pennwalt Corp., PVDF (for Polyvinylidene Fluoride) has been well known as a material of construction for chemical-handling applications.

Cleaning-in-Place of powder-handling equipment in food, beverage and dairy plants

Dry or wet, nozzle selection, temperature, pressure and drying method among key decisions to be made
It goes without saying that a modern food or beverage plant handles lots of powders, either as raw ingredients or finished products. To handle all this stuff, plants are equipped with powder transport and conveying systems as well as powder silos, feeders, blenders, de-baggers and filling machines.

Non-contact radar level meter improves reactor vessel measurement

Chemical manufacturer reduces cycle time and limits chemical vapor exposure
A North Carolina-based specialty chemical manufacturer, a major producer of insect repellent, was looking for a better way to measure the liquid level in its glass-lined agitated reactor.
