This slaughterhouse in Noway focuses on the production of beef, pork and lamb. The main task of the VOLUTE™ dewatering press was to replace a DAF unit and help increase the quality of the dewatered substance to a non-liquid form.
The requirement was to dewater the manure wastewater with a stable concentration of about 0.6 % to 20 % DS, and reach the highest possible capture rate in order to reduce the presence of COD in the filtrate.
The main purpose of recommending EC model to this site was the capture rate increase and cleaner filtrate disposal.
VOLUTE was operated at its minimal possible capacity. The main sludge pump’s capacity is around 12-15 m3/h however it was not possible to run it faster than 4 m3/h because the mixing pipe system was set up to lower throughput maximum. According to the customer, the setup can be adjusted if needed.
AMCON’s solution reached the requirements for wastewater dewatering as mentioned above with very efficient COD reduction by 61 %, from 9055 mg/l (inlet wastewater) down to 3500 mg/l (outlet filtrate).
