PITTSBURGH, PA, July 28, 2015 -- In an effort to preserve the beaches of the Northern Adriatic Sea, the regional government in Rimini, Italy, has partnered with HERA, operator of the regional wastewater treatment plant (WWTP), to expand its existing operations while absorbing other WWTPs in the area.
This has increased service from a population of 220,000 to 560,000 people who migrate to the area during the summer season. By utilizing the best available technologies, Rimini has successfully inaugurated Europe's largest membrane bioreactor (MBR) wastewater treatment facility and is on-track to eliminate discharges to the Adriatic by 2020.
The new Rimini wastewater treatment facility is a benchmark for the world in terms of operational efficiency and effectiveness. The facility utilizes Evoqua Water Technologies' Memcor® and Mempulse® MBR modules throughout. Mempulse is a sub-brand within the Memcor family.
The new expanded MBR line has an average daily flow that varies from approximately 55 million liters/day to more than 76 million liters. The target of the MBR line is to achieve an effluent with a quality higher than the stricter Italian legislation for reuse. Membranes are installed in tanks fed by gravity that can switch on/off according to need in order to ensure maximum flexibility. The total filtration area is approximately 150,000 square meters. In total there are nearly 4,000 Mempulse MBR modules utilized in the new expansion.
Construction of the expansion began in 2012, and the new Mempulse MBR line was put into operation at the end of 2014 . Following performance validation processes, the facility reached full capacity a few months thereafter and is actively recovering purified water for reuse and minimizing discharge.
Because the Mempulse MBR system eliminates the need for secondary clarifiers and tertiary treatment, it results in superior effluent quality, and a lower lifecycle cost with a smaller footprint. By incorporating Mempulse MBR modules, the Rimini WWTP was able to decrease its footprint and reduce project and operating costs while still treating the wastewater to their strict specifications.
