"Ithaca’s clean-water plant has boosted biogas production and energy generation in a project that will yield $9 million in guaranteed savings over a 20-year contract. The Ithaca (New York) Area Wastewater Treatment Facility now generates nearly half its electricity on site, and the plant team hopes a new biogas system can eventually meet most if not all power needs."

"An Iowa city’s $38 million [wastewater treatment] facility renovation includes combined heat and power, biosolids reuse, effluent heat recovery, water-saving landscaping, and more."

Mining for Lithium in Geothermal Brine: Promising but Pricey

Power Magazine, Mar. 2015, by Gail Reitenbach.

"Brine, the waste stream of the geothermal power production cycle, is usually considered a nuisance. High in corrosive minerals, even when reinjected, it’s challenging to manage. So when Simbol Inc. showed it had a way to turn this waste stream into a revenue stream by mining it for high-value minerals like lithium, a lot of people got excited. However, just as this article was going to press, a lot of people got laid off."

Watts in a Drop of Water: Savings at the Water-Energy Nexus

ACEEE White Paper, Nov. 5, 2014, by Rachel Young. [Free registration required to view full-text.]

_total_systems_approach_to_wastewater_tr


"Industries that must treat or pretreat their wastewater face varied challenges. Any given facility’s needs are best met by a total systems approach (TSA) — a fully integrated solution that includes all pieces of the puzzle instead of uncoordinated components and systems. The approach includes a collaborative evaluation up front to understand a facility’s requirements, apply proven designs and materials, and select innovative products that achieve the optimum water quality at the best life cycle cost."
