Water Treatment Equipment Rental: DAF Systems and LDP Multi-Disc Screw Press Skids

wastewater

The efficient management of industrial wastewater now plays a central role in companies’ sustainability, operational continuity and competitiveness. The need to comply with increasingly stringent environmental requirements, ensure process stability and control operating costs calls for the adoption of robust, flexible and rapidly deployable technological solutions.

In this context, equipment rental offers a strategic alternative to traditional investment, providing immediate access to advanced technology without tying up capital.

The rental of DAF systems and LDP skids provides an effective, modular and ready-to-operate solution that can be adapted to different types of effluent, sludge and operational requirements.

DAF – High-Efficiency Dissolved Air Flotation

DAF (Dissolved Air Flotation) systems are designed to maximize solid–liquid separation, ensuring high removal efficiency for suspended solids, oils, fats and colloidal matter, particularly when combined with suitable physicochemical treatment.

The operating principle is based on dissolving air in water under pressure. This pressurized, air-saturated stream is then released into the flotation tank. Depressurization generates microbubbles that attach to the particles present in the effluent, causing them to rise to the surface, where they are mechanically removed by a scraper system.

The counter-current hydraulic configuration is one of this technology’s main advantages, enabling:

» A higher concentration of microbubbles in the inlet zone, where the solids load is greatest
» Better contact between microbubbles, flocs and suspended particles
» Minimal carryover of solids into the clarified water
» Greater stability in treated-water quality

In addition, the systems can incorporate recirculation pumps with open impellers, capable of handling water containing solids and fibers, significantly reducing the risk of blockages.

They may also integrate:

» An intuitive, easy-to-operate HMI console
» Remote management and support systems
» Turbidity sensors for continuous monitoring of treated-water quality
» Chemical preparation and dosing systems, when required

Plug-and-Play LDP Skid – Low-Energy Sludge Dewatering

The LDP skid, based on multi-disc screw press technology, is a compact and efficient solution for sludge thickening and dewatering. Designed around a plug-and-play concept, it integrates the main equipment required into a pre-assembled unit, allowing rapid installation, straightforward commissioning and stable operation.

This configuration combines mechanical robustness, low energy consumption and reduced operating costs, optimizing both dewatering performance and ease of maintenance.

The equipment operates through two main zones:

» Drainage or thickening zone: the wider disc spacing allows the initial removal of free water
» Compression zone: the progressive reduction in spacing and increase in pressure promote more intensive dewatering

This configuration makes it possible to:

» Operate with sludge containing a low concentration of solids
» Significantly increase the dry matter content of dewatered sludge
» Reduce the final sludge volume
» Lower transport and final disposal costs

Its main advantages include:

» Very low energy consumption compared with conventional technologies such as centrifuges
» Low maintenance and operating costs
» Low noise levels
» Reduced aerosol generation
» Continuous and stable operation
» Direct feed capability from thickeners, biological reactors or sludge tanks, depending on process conditions
