The ANDRITZ Aqua-ScreenTM​​​​​​​ water treatment equipment ensures maximum online availability with minimum maintenance and customized fit requirements in many solids/liquid separation processes. Used in diverse industry sectors such as municipal sewage treatment, combined sewer (CSO) industrial wastewater, pulp and paper, food processing, chemical processing, and raw water intake.

The SpiroSand is a simple and reliable piece of equipment that removes sand and heavy sediments, as well as floating debris from sewage effluent before they are able to plug equipment or cause abrasive wear to downstream machinery.

To meet the growing demand for small sewage treatment plants, ANDRITZ SEPARATION has designed the AquaSpir screen, a shaftless screw screen which not only screens and conveys the solids, but also dewaters and compacts the screenings – all in a single integrated unit.

The PowerPress is a robust and efficient, but nonetheless reasonably priced dewa¬tering unit for a large number of sludge. Its long filtration zones and high pressures ensure optimum dryness levels, and the reduced polymer consumption and ease of maintenance induce significant cost savings.

The ANDRITZ Delkor horizontal vacuum belt filter makes use of the most modern design capabilities to make it an efficient and reliable solid/liquid separation unit able to operate under the most arduous conditions.

Reliable dewatering is essential for continuous production. All our filtration expertise was put in our new heavy-duty belt press to give you a solution with the highest throughput, lowest operating costs, and lowest required residual moisture.

The PowerDrain gravity belt thickener is a highly efficient and economical solution for sludge thickening. Specially designed ploughs as well as the very large open area under the belt optimize the draining effect.

The Hydrasand continuous sand filter is an economical sand filter for continuous cleaning of sand to achieve efficient effluent cleaning.

Our Aqua-Guard fine screen is one of the simplest screening systems on the market (ease of installation, low supervision and maintenance), with a sequential functioning (increase screening capacity, avoid the purchase of a downstream screening device, reduce water and energy consumption).

The C-Press is the latest result of more than 20 years of experience in designing and manufacturing screw presses. By combining multiple ANDRITZ SEPARATION dewatering technologies, its uniquely compact design and its purpose developed features enables easy, operator-free sludge dewatering together with low energy and maintenance costs.

The HydraSieve is a simple, highly efficient screen, designed for solid/liquid separation. Thousands of worldwide installations on all types of applications prove its efficiency.

The PowerDrum (PDR) is considered to be an easy and efficient sludge thickening solution prior to the dewatering process and can deal with biological sludge throughputs ranging from 15 to 180 m3/hr. With its simple design and small footprint, the PowerDrum is easy to install and requires little supervision and maintenance.

The highly successful linear screen has proved itself in that most gold projects incorporate this unit for pre-screening, de-sanding, carbon scavenging, and de-sliming of loaded carbon.
