Mechanical Wastewater Pre-treatment Equipment
Mechanical pretreatment in civil wastewater treatment plants involves sewage lifting, screening, sand and grit removal, and sedimentation. This primary stage removes large solids and debris, preventing damage to downstream equipment and improving overall treatment efficiency. It’s a crucial first step in ensuring safe and effective wastewater management.
Sewage Lifting Equipment
Among the most enduring products in SAVECO’s extensive portfolio, Archimedean Water Screw Pumps are available in a wide range of sizes and configurations, tailored to suit diverse applications.
Since the late 1970s, a few thousand Archimedean Water Screw Pumps—ranging from 0.5 to 4 metres in diameter and handling up to 4,500 litres per second—have been reliably operating worldwide. Featuring double and triple flight designs and drive power of up to 500 kW, they deliver constant efficiency, year after year. Their robust construction, minimal maintenance requirements, and ability to handle variable flows make them ideally suited for wastewater, stormwater, and industrial pumping applications in even the most demanding environments.
SCREENING AND COMPACTING EQUIPMENT
SAVECO® provides advanced screening and compacting equipment for efficient solids-liquid separation during the primary treatment stage of wastewater, ensuring reliable and effective processing.
SAVECO’s screening portfolio includes dedicated Channel Screens, versatile Channel and Pit Multi-function Screens, fully Enclosed Screens, Equipment for Compacting and Conveying Screenings and complete Compact Pre-treatment Plants. These robust systems are designed to deliver reliable performance across a wide range of municipal and industrial applications, helping to reduce maintenance requirements, improve workflow efficiency, and support compliance with increasingly stringent environmental and operational standards in modern treatment facilities.
SEPTAGE RECEIVING STATIONS
SAVECO’s Septage Receiving Stations provide efficient solutions for municipal wastewater treatment plants. Septage is the wastewater and solids pumped from septic tanks. Our stations screen, dewater, and control septage deliveries, protecting downstream equipment, ensuring regulatory compliance, and improving plant performance for cleaner, more sustainable wastewater management. Designed for ease of operation, these systems minimise odours, reduce manual handling, and enable safe discharge, while offering dependable performance, lower lifecycle costs, and seamless integration into existing treatment infrastructure.
SAND AND GRIT SEPARATION AND FLOATING MATTER REMOVAL EQUIPMENT
An essential step in mechanical wastewater pre-treatment is separating sand, grit, and floating matter like oil, grease, and solids. SAVECO® offers a comprehensive range of equipment in various sizes and performance specifications to meet diverse treatment needs.
For sand and grit separation and the removal of floating matter, SAVECO® offers a comprehensive range including Travelling Bridges, Aerated Grit Chambers, Sand and Grit Separators and Classifiers, Sand Washers as well as Sand Washing Classifiers. These solutions are engineered to maximise capture efficiency, minimise wear on downstream equipment, and ensure consistent, reliable operation. Designed for ease of maintenance and long service life, they help reduce operating costs, improve process stability, and enhance overall treatment plant performance in demanding environments.
