Boiler Water Essentials: Water Is Water (Not)

When it comes to water used in boilers, it is important to remove potentially problematic impurities. This offers a potentially huge return on investment, even with the prevention of just one major upset, let alone recurring failures Several decades ago,…

Reducing sludge stickiness with polyaluminum chloride: an investigation of two conditioners

Polyaluminum chloride (PACl) is used as a conditioning agent for reducing the stickiness of waste-activated sludge in wastewater-treatment applications. Presented here is a study comparing two PACl species with different degrees of polymerization The sticky behavior of waste-activated sludge (WAS)…

Water scarcity worsening

A few months ago, this column addressed the megadrought in the U.S. Southwest and the increasing concerns over water scarcity [ 1]. Since that time, the drought in that region of the U.S. has continued, further impacting communities across the…

Wastewater Treatment: Three Steps to Achieving Discharge Compliance

To ensure that wastewater discharge meets all compliance requirements, plants should adopt a multi-tiered approach, rather than assuming that the downstream treatment facilities can handle all potential contaminant loads Most industrial manufacturing facilities are required to meet strict limits on…

Extending the operating temperature of biological phosphorus removal

Currently, enhanced biological phosphorus removal (EBPR) techniques in municipal wastewater-treatment plants (WWTPs) do not work well at temperatures above 25°C, which is common in warm countries. This limitation is expected to extend to more countries with the advent of global…
