BioAir Solutions Clean the air from wastewater treatment plants without carbon Using its proprietary EcoBase synthetic media, this firm has developed a line of odor control products (photo) that remove both organic and inorganic odorous compounds from the airstreams of…

Ask the Experts: Water-hydrocarbon separation

Question: How are hydrocarbons best removed from water? Answer:  First, the type of hydrocarbons present must be identified. Typically, the hydrocarbons in question are in the form of oil or an oil-like substance. In that case, the miscibility of oil…

Desalination: From Sea to Shining Sea

Athough the municipal water demand is considerably greater than that of industry, many of the municipal needs are addressed by relatively basic technologies, while industrial requirements can only be met with advanced treatment options. And, as industrial water demands continue…
