melegvizet

Melegvizet is a type of modular sewage treatment plant developed in Hungary. It has been in use since the 1980s and is designed for small communities and settlements. The Melegvizet system uses a combination of mechanical and biological processes to treat wastewater.

The plant can be scaled up or down depending on the size of the community it serves, ranging from a few dozen to several hundred households. Its modular design makes it easy to expand or modify as needed. The system uses a hot gas or pneumatic aeration system to promote beneficial bacteria growth.

Melegvizet treatment plants can treat a wide range of wastewater, including household sewage, greywater, and stormwater runoff. They are designed to remove pollutants such as suspended solids, biochemical oxygen demand (BOD), and nitrogen. The treated wastewater can then be reused for irrigation and other non-potable applications.

The Melegvizet system has been recognized for its innovative use of hot gas aeration, improving bacterial activity and reduced sludge production. Additionally, its compact design and weather-resistant construction make it an effective solution for remote or under-resourced areas. Installations of Melegvizet have been reported across Europe and in other regions where similar wastewater treatment needs are present.

Although the Melegvizet system is not a standardised industrial-scale technology, it plays a significant role in reducing water pollution at local and community levels.
