A lifeline for pools? “Digital boilers” provide innovative rethink of waste heat reuse

Envirotec Magazine

Swimming pools threatened with closure because of skyrocketing heating bills could get a reprieve from a new technology for waste heat reuse that is being described as a potential game changer. Deep Green’s system draws upon techniques used to cool electronic components. metre x 1 metre x 0.6

Liquid air: A cool option for energy storage?

Envirotec Magazine

Liquid Air Energy Storage (LAES) uses electricity to cool air until it liquefies, so it can be stored until an opportune moment arrives when it can be brought back to a gaseous state and used for power generation. Like other energy storage solutions, the idea of liquid air energy storage is to balance out electricity supply and demand.

Heat recovery from waste

Envirotec Magazine

Zero Liquid Discharge, or ZLD, is a technique which aims to discharge no liquid waste to the environment, instead recovering as many products from the ‘waste’ stream as possible and leaving just water, which can be re-used. Vapour compression evaporation can recover up to 95 per cent of the wastewater as distillate.

Study shows power plants can recycle water using wastewater from oil and gas mining

Envirotec Magazine

The researchers modeled various scenarios for using “cooling tower blowdown” and “produced water” to treat each other. Cooling tower blowdown is wastewater produced by thermoelectric power plants, while produced water is created by hydraulic fracturing mining for oil and gas. uses as much water as thermoelectric power generation.
