Established in 2002
Sludge Drainage System (Sedimentation Basin)
Enclosure may vary depending on the specifications of the product (water-proof/explosion-proof, Single-Phase/Three-Phase Power).
Description
RPMTECH's Sludge Drainage System is comprised of an efficient auxiliary scrapper (attachment) and a fail-safe MHP (or DHP) Quarter-Turn Actuator (s) attached to a segmented ball valve. The auxiliary scraper attachment and the immediate opening/closing of the ball valve allows for resistance-free (Rabbit-Hole-free) drainage, which helps reduce sludge solidification within the hopper. Also, the actuator is equipped with advanced control modes optimized for efficient drainage and valve disk protection.

Summary
Sludge Drainage System (Sedimentation Basin)
Efficient Sludge Drainage System for the Sedimentation Basin (water treatment)
Prevents Sludge Solidification
Efficient Sludge Extraction
Reduced Costs
Many sludge collectors (scrapers) have blind spots within the hopper, which means that sludge can be left uncollected only to solidify within the sedimentation basin. RPMTECH's auxiliary sludge scraper attachment can effectively prevent this by reducing any blind spots in the hopper.
RPMTECH's MHP/DHP Quarter-Turn Actuators are capable of opening/closing the valve in 5~8 seconds or less. Immediate opening of the valve will allow the sludge to immediately whirl down the drain resulting in a more efficient and immediate drainage process. This will prevent the formation of rabbit holes, which is the cause of inefficient drainage.
Sludge moisture content 1.71%P decrease, unnecessarily wasted water 42.6% decrease, sludge drainage efficiency 48.7%. These statistics are the start to reduced installation and operation costs in the long run.
