Coarse screening is the first stage of wastewater treatment and involves the use of screens with large openings to remove larger debris.
This process is carried out with belt screens and protects downstream equipment, such as pumps and pipes, from damage caused by solids.

The efficiency of the coarse screening system is crucial to ensure the smooth operation of the entire treatment plant. It filters down to 3mm.

After the first stage, the wastewater passes through a fine screening process, which uses disc screens with smaller openings to capture smaller debris such as hair, sand, and organic particles.

This step is critical to prevent clogging and wear on subsequent equipment, such as pumps and filtration systems. this process filters down to a size between 1000µ and 200µ, improves efficiency, reduces the need for maintenance and increases the longevity of the equipment.

Sludge dewatering equipment is designed to treat and reduce the volume of sludge produced by industrial processes, such as waste water purification or chemical processing. Sludge is separated from water by mechanical filtration, centrifugation or through the use of filter presses. The main objective is to reduce moisture, thus minimising volume and disposal costs. The material is easier to handle, transport and can be optimised for further treatment, such as composting or incineration. The process contributes to the sustainable management of industrial waste.

Dissolved air flotation is a separation process used to remove oils, fats, and suspended solids from wastewater. In this process, water is saturated with pressurised air and then released into a tank at atmospheric pressure. The tiny air bubbles stick to the suspended solids, causing them to float to the surface, where they are removed with scrapers.

This method is particularly effective for treating oily wastewater or wastewater with high concentrations of fats and oils, often found in food or petrochemical industries.

Sand filtration is a physical treatment method that uses beds of sand or granular materials to remove suspended solids and fine particles from wastewater.
The water is passed through the sand bed, where the particles are trapped.
This process is effective in reducing water turbidity and removing particles that were not removed during previous treatment steps.

Sand filtration is commonly used as the final treatment step before disinfection and release of the treated water into the environment.
