This system was designed and custom developed for Valders Stone in Valders, Wisconsin to handle up to 1000 GPM with a fluctuating percentage of solids in the water and the need to operate over the weekends when no operators are present.

To adjust and compensate for the fluctauting amount of solids in the water the system was designed with sensor that detects the total suspended solids in the sump pit containing the inflowing dirty water and adjusts the amount of flocculant accordingly in order to create large savings in flocculant.

Since this system needs to run 24 hours a day it was also designed with a back-up pump in the sump pit to ensure that down time is eliminated and that the system can operate on its own through the weekend when there is little or no operators on site. The Y shown in the picture below shows the feed line coming from each of the 2 sump pumps.

The 100,000 Liter silo is made out of 304 stainless steel and was custom sized to fit within the height of the building.

The filterpress has 20, 800mmx800mm plates is fully automated including our automatic shaking system to ensure the complete dislodging of all the dry filter cakes.

The final result is water that runs from 12-20ppm vs. 60-80ppm with their sedimentation tank system that we replaced according to Jeremy Corser at Valders Stone and dry cakes as shown by the picture below sent to me from Jeremy at Valders Stone. In the picture you see one of the cakes automatically falling into the collection pit below which stores the dry cakes until they are hauled off by their loader.

Matec would like to thank Jeremy and Valders stone for sending us the photos as well as for providing us the data on the improvement of their water clarity from 60-80ppm down to 12-20ppm with the Matec Water Treament System.
