CASE STUDY
WASTEWATER PURIFICATION
The treatment of industrial and civil wastewater is an industrial process fundamental for the safeguard of the environment and of the people living nearby. The wastewater must undergo a purification process, both as a function of recycling and to respect environmental safeguard parameters. Some processes or commonly used machineries may give rise to consistent malodorous emissions.

CONTEXT
In the majority of wastewater treatment plants, substances responsible for bad smells are ammonia (NH3), hydrogen sulphide (H2S) and Mercaptans (RSH). Said substances are perceptible to human’s sense of smell even in extremely low concentrations and are responsible for annoying odours.

CHALLENGES
OPTIMISE AND SIMPLIFY
Limited spaces, the high performances requested, the presence of other plants with which to interact, the interferences and the necessity to keep the purification plant working 24/24h are just a few of the challenges that BMB plants must face. In this case, it was necessary to obtain an almost total efficiency of removal, combined with a plant management that was easy and economically convenient.
SOLUTION
CREATE A CUSTOMISED PURIFIER
Realisation of an optimised purifier with high level of automation, with a customised parameters control, remote monitoring and alarm system, in order to transmit maintenance interventions.
The plant has been structured with the following scheme:
The polluted air stream passes through two wet washing towers (scrubber) capable of reducing the acid compounds (hydrogen sulphide H2S); odours are subsequently removed by a biofiltering unit.

TURNKEY PLANT
Each industrial air purification plant with scrubber tower realised by BMB is custom-designed after an accurate field study phase. The initial study of conditions, context and problems to solve allows our technicians to recommend targeted and personalised solutions, dedicated plants and specific technologies for each kind of problem.
