CHEM BaG

The CHEM BAG system is an innovative solution for effectively dewatering bio-sludge generated from WWTP (Wastewater Treatment Plants) and STP (Sewage Treatment Plants). This system utilizes specially designed filtering bags that allow water to pass through while retaining the sludge within, ensuring efficient separation of solids and liquids. The filter bags are securely housed within durable SS304 or FRP (Fiber-Reinforced Plastic) structures, providing robust support and long-lasting performance.

The process begins in the flocculation tank, which is equipped with an agitator to ensure thorough mixing. Under the influence of a suitable polymer, either cationic or anionic, the sludge undergoes a flocculation process, leading to the formation of larger, more manageable flocs. These flocculated solids are then transferred into the filter bags, where the dewatering process continues.

The system features a level control mechanism that monitors the sludge levels in the feed tank. When the sludge reaches a predetermined high level, the feeding process is automatically controlled to prevent overloading. As water is progressively removed from the sludge, it passes through the filtering bags, leaving behind a concentrated sludge mass. The dewatered sludge bag is then removed, securely tied, and stored in open-air conditions for further drying, reducing moisture content to the desired level.

The duration required for complete dewatering to achieve 50% to 60% dry solids (DS) typically ranges between 10 to 15 days, depending on environmental factors and system configuration. This efficient and customizable process ensures optimal sludge management while complying with environmental regulations and standards.
