CASE STUDY - SOFT DRINKS
CHALLENGES
A new soft drink factory, Coca Cola Icecek, was built in Azebaijan. This plant produces sanitary and industrial streams which require separate efficient treatment before discharge.
The WWTP had to produce a continuous flow of high quality effluent and therefore should be able to cope quickly with hydraulic peaks, toxic shocks and future expansion of the plant capacity. Another challenge was the construction at a remote and extreme cold climate area.
SOLUTION
A new WWTP based on Moving Bed Biofilm Reactor (MBBR) and Media clarifier technologies. The industrial line includes three stage AGAR® MBBR followed by a Media Clarifier (MC). The media clarifier is a unique patented clarifying technology, developed especially for MBBR effluent. The MBBR effluent characteristics, containing mainly the sloughed-off biomass, are different in particle size distribution and biomass morphology compared to activated sludge. MC has several advantages as simple operation, small footprint and no need for chemicals for sedimentation.
The construction works lasted for only 3 months due to the use of prefabricated tanks, which also considered careful building practices to withstand the cold weather.

RESULTS After a startup that lasted for 4 weeks, the AGAR® MBBR & MC produced a high quality effluent achieving 96% removal of BOD and producing high quality effluent according to the required standards. The MBBR process copped well with the cold temperatures during winter and with deviations in inlet loads due to production changes.
SUMMARY
The AGAR® MBBR + MC system allows high and stable removal efficiency of organic loads and solids. The results indicate that the MBBR is capable of meeting regulatory effluent requirements in a compact system and at cold climate. The usage of prefabricated tanks enabled short erection time and minimal interference to the operations at the production site.
