Ryan Process can supply you with a wide range of filtration systems for industrial, and municipal wastewater, water and groundwater. Envirodyne Systems, Inc. Sludge Bagger System

If your water or wastewater treatment plant is small (e.g., average daily wastewater flow less than 200,000 gallons), a bag dewatering and disposal system could save you maintenance, energy, and money. This system uses gravity to dewater biosolids and has only three moving parts - the sludge pump, polymer pump, and polymer mixer. With the assistance of Mother Nature, the bagger achieves high performance without the auxiliary vacuum or pressure devices needed with other dewatering systems. We offer three models: a six-bag, eight-bag, or 10-bag unit. Operator time for this system is minimal. All the operator needs to do is take off the previous day's bag, tie it with a steel tie just like you would tie a garbage bag, and stack it outside. Every other day, the operator makes a new batch of polymer and pushes the start button. The system is designed to be semi-automatic and does not require continuous operator attention during the dewatering operation. How the Dewatering and Disposal System Works After polymer conditioning, biosolids are placed in a gravity drainage unit that is open at the top to simplify cleaning and maintaining the system. The slurry is then continuously dewatered as it falls into one of the bag chambers. Water drains through the woven material from which the 23-gallon bags are made and is collected and returned to the head of the plant. Each automatic operating cycle typically includes a one to two hour fill period followed by a one to four hour additional gravity drainage period and produces approximately 22.5 pounds of dry biosolids per bag. Using a modified fork dolly, only one person is needed to disconnect the bags and stack them on pallets for further dewatering. Once the bags are stacked outdoors, natural evaporation from within the bags increases the solids content to as high as 40 to 60 percent. Bagger System Calculations The design basis is aerobically digested sludge type, production rate of 50 pounds of dry solids a day and concentration of one percent. The design calculations include the monthly solids loading rate, the monthly bag processing requirement, the dewatering cycles required per month, and the cost comparison.
