Removal of the normal-hexane extracts in raw wastewater

Frozen food factory

This frozen food factory was troubled with a high content of normal-hexane extraction material (mainly oil and fat content) concentration in the waste water discharged into the sewage. However, other high hurdles such as the need of large-scale expansion for dewatering facilities or site prevented them from reaching the best solution. In such situation, AMCON received their consultation if Volute can remove oil and fat content.

Nevertheless, the pieces of glass need to be washed before having been shipped to another factory where the final product will be made and this cleaning water needs to be treated somehow. They had been using a belt press for dewatering sludge generated from their wastewater treatment plant, but because of its age, they started looking for a new sludge dewatering system.

Dramatic Change in Efficiency Brought by The Installation of The Volute Dewatering Press

Yamauchi Company

Since sludge dewatering equipment had not been installed in their wastewater treatment plant, sludge had been treated with a sand filter and took them 1 to 2 weeks to dry. Furthermore, the dried sludge had been picked up and placed in a tub by 30 employees, and it took them an hour to complete their task. It was not only time-consuming but also required high labor cost. However, this was not the only issues that they had been confronted with in sludge treatment. Since the sand filter is installed outside, sludge treatment can be significantly influenced by the weather. For instance, there is a huge disparity in temperature between summer and winter, and this undesirable environment had affected their productivity to a great extent. Moreover, the fact that the time when the sludge dries depends on the weather made them difficult to treat sludge according to plan.
