Succeeded in stable supply of polymer to two equipment from one Polymer Make-up System

Meat Processing Factory

This customer was newly proceeding with a plan for installing a wastewater treatment plant. As the wastewater discharged from the factory contained much oil, the customer was planning to install a dissolved air flotation system in the wastewater treatment process. The VOLUTE™ Dewatering Press, having strong resistance against oil, was considered for dewatering of the sludge.
We immediately tested the sample sludge and found that two types of polymer of both cationic and anionic polymer were needed to dewater the sludge. This means three Polymer Make-up Systems would be necessary; two for the sludge dewatering press and one for the dissolved air flotation system.

However, we were able to eliminate one Polymer Make-up System, thanks to the suggestion of the person in charge of ECP, to supply the anionic polymer from one Polymer Make-up System AF series to both the dewatering equipment and the dissolved air flotation system, by taking advantage of the features of our Polymer Make-up System AF series; “stable supply of polymer” and “easy management”.
Both the dissolved air flotation system and the sludge dewatering press can operate safely as both the dissolving tank and the stock solution tank of AF series equipped with sensors for idling prevention. Moreover quick supply of polymer with stable concentration is possible with AF series because it dissolves liquid type polymer.
The wastewater treatment plant has constructed and started treating wastewater stably without any problems.

Dewatering low-concentration sludge

Manufacturing Plant of Synthetic Fiber Materials in Indonesia


Before installation of VOLUTE™ Dewatering Press, they threw cake into their dryer after dewatering by their belt press . Drain of Synthetic Fibers purified from oil was not suitable for micro-organisms and was low MLSS. In addition , sludge concentration from thickening tank was quite low(6,000mg/L). So, Water content in Sludge cake became 92% by belt press machine. Because of throwing the soft sludge like Tofu, the load was pretty high.

AMCON’s offer for a solution

Since VOLUTE™ Dewatering Press adopted the unified structure that serves two functions, thickening and dewatering in the single machinery, the low concentration sludge can be dewatered. The drum filter, because of the clog-free, realizes higher speed of filtering phenomena per filtering area as compared to the methods, and the sludge is instantly thickened by gravity. They can constantly throw sludge into the dryer by installation of VOLUTE™ that can keep 85 % of water content so easily.

Dewatering of oily sludge without clogging

Chicken processing plant in Ukraine


The chicken processing plant in Ukraine had a big issue on tremendous amount of sludge disposal costs due to direct disposal of the sludge without dewatering. They had tried to look for a suitable sludge dewatering equipment for easy dewatering of the oily sludge, however it was almost impossible to find.

AMCON's offer for a solution

The customer installed ES-303 model understanding of the advantage of VOLUTE™ Dewatering Press; high resistance to oily sludge.
Customer’s comment: “We used to hesitate to install dewatering equipment due to anxiety for problems such as clogging and frequent maintenance of equipment for dewatering of oily sludge. However we are surprised at the fact that VOLUTE™ hardly has clogging. The full automatic operation is very helpful for easy management. The water content in sludge cake is as good as 71.5%, which is the performance of the VOLUTE™ Dewatering Press we are greatly satisfied with. We really realize that the installation of VOLUTE™ is the best choice we made.”
