Lamix - anaerobic sewage treatment EGSB
Executed as "design and build" contract anaerobic wastewater treatment in paper Lamix is one of the first of it's kind in Polish and Central European P&P.
WWTP built in EGSB (expanded granular sludeg bed) anaerobic reactors technology is heavy duty, rubust and easy to extend. It purifies industrial sewage from recycled paper factory (tissue production) characterized by large loads of pollutants. By-product of this type of treatment is the production of biogas, - high-calorie fuel, which can be further used for example to produce electricity for the plant. Here in Lamix up to is produced 1000Nm3/d of high of methane content biogas is produced per day
Treatment plant was opened at the end of May 2009, her performance at the level of up to 400 cubic meters per day enable achievement maximum production capacity. The solutions allow to rationalize consumption of natural resources and to guarantee high quality purification. The cost of building pre-treatment, with effective use of biogas, should return in a few years.
Because of high content of insolubles, plant was equipped with a special control system. It is very important for the paper industry. Used one protects anaerobic reactors from calcium carbonate (CaCO3) precipitation inside treatment installation.
Wastewater treatment system includes:
- removal of the suspended solids(in factory)
- insolubles control system
- buffer tank with full measurement
- two anaerobic reactors of the EGSB type
- biogas flare
- service building with all systems, along with pumping and conditioning
- sludge backup and aerobic refreshing tanks
- process control and automation
The plant is equipped with dual control and automation system that allows for facility management, both from the local control room and the main control room of the plant.
The project is the use of EU funds under the Operational Programme Innovative Economy 2007-2013 (Priority Axis 4 Investments and Innovations). WWTP is located close nearby "Nature 2000 sites".
