MSc. Petr Dolejš

Dolejs Petr

Thesis topic:

Maximal recycling of energy from waste waters in future residences

The topic results from a new view on waste waters as a source of energy and valuable materials (including water alone).

WASTEWATER is a RENEWABLE RECOVERABLE SOURCE of POTABLE WATER, ENERGY and RESOURCES. Dr. George Tchobanoglous, Orlando 2013

Motivation

Anaerobic fermentation lies at the heart of the energetic utilization of waste waters. This fermentation is realized in high-speed bioreactors and may be applied to classical (diluted) waste water from households as well as for separated i.e. concentrated waste water containing large amount of organic substances (so called black water). The first approach mainly applies to residences already built in the typical centralised manner; the second approach is about small, detached residences as well as future cities which are to prefer the decentralisation principle. Main technological problems are related to effective separation of organic pollution using membrane bioreactors and subsequent pollution processing in anaerobic fermenters followed by anaerobic fermentation at low temperatures (10 – 15 °C). The main desired product of this process is biogas as a source of electrical energy and heat.
