At KLINGER Portugal, we are ready to respond to any challenge with speed and efficiency. For this reason, we provide equipment rental solutions adapted to different needs. We ensure that our clients have access to the most advanced technology, quickly, with flexibility, and full control over operational costs.
Among the various equipment we offer for rental, we highlight the LDP (MultiDisc Screw Press), Wave Separator (Rotary Disc Thickener), Aerators, and DAF systems.
LDP – MultiDisc Screw Press
The LDP is an equipment designed for sludge dewatering, while also being able to operate as a mechanical thickening system. Its design incorporates two distinct zones, engineered to optimize process efficiency.
In the first zone, the filter discs have wider spacing, which favors the initial extraction of water and promotes sludge thickening. In the second zone, the spacing is progressively reduced and the pressure increased, enabling higher dry solids content in the final product.
Thanks to this configuration, the system allows direct dewatering from aeration tanks, ensuring high performance levels without compromising treatment efficiency.
Wave Separator – Rotary Disc Thickener
Designed for solid-liquid separation, it can perform screening, thickening, and dewatering functions. The continuous and synchronized rotation of oval discs ensures a self-cleaning operation, reducing downtime and maintenance needs.
It can be used in various applications and industries. Its universal design allows it to operate as a simple thickener for waste and effluents with concentrations from 0.5% to 10%. The slot openings can be adjusted according to the treatment purpose, offering great adaptability.
Aerators – Surface and Submersible
Aerators are the ideal solution for mitigating odors and optimizing the performance of the aerobic reactor. Easy to install, they are especially effective in recovering biological processes in WWTPs.
» Submersible Aerators: ensure efficient deep oxygenation; recommended for closed or deeper tanks.
» Surface Aerators: provide high oxygen transfer, ideal for temporary reinforcement or rapid capacity increases.
DAF – Dissolved Air Flotation Units
Engineered for maximum efficiency, Dissolved Air Flotation (DAF) units operate in counterflow, discharging sludge at the system inlet. This design ensures better solids retention, while the high concentration of microbubbles provides process stability, avoiding performance losses.
With a venturi-type pressurization system, compressed air is used optimally, reducing energy consumption by up to 50%. Recirculation pumps allow solids passage up to 20 mm, preventing blockages and increasing process reliability.
The process is based on attaching microbubbles of air to solid particles, making them lighter and quickly lifting them to the surface, where they are efficiently removed.
