Utilizing Geotextile Container Bags is a very efficient method for dewatering and disposing of bio-solids at a small waste treatment facility. Container dewatering bag investment requirements are very low compared to other mechanical dewatering systems. The container bag fits into a standard 20 or 30 yard roll off. Sludge is pumped into the bag and the water separates from the solids and drains through the pores of the bag leaving 99% of the bio-solids in the bag. The bag pumping cycle is repeated over and over until the bag has reached its maximum capacity. A flocculant is used to aid in the dewatering process and prevent plugging the pores of the bag.
