Flocculation

Overview

Overview

Flocculation and sedimentation are widely employed in the purification of drinking water. Flocculants are used in water treatment processes to improve the sedimentation or filterability of small particles, for example to aid removal of microscopic particles that would otherwise cause the water to be turbid (cloudy) and which would be difficult or impossible to remove by filtration alone.

Correct flocculation requires reliable flow management from pumps systems and mixers and dosing pump systems – and Grundfos can supply all components. The Grundfos range of SE pumps are specifically designed for durable use and flow management, and can be installed dry or submerged. They offer the reliability you need to ensure correct sedimentation.

Grundfos can supply complete dosing pumps systems for large or small volumes and based on different technologies for flocculation, disinfection, and pH adjustment. Moreover, the Grundfos range of electronic and electrochemical accessories offers complete control of your dosing and disinfection processes and can be seamlessly integrated into your system.

Water quality improvement with an efficient, economical system for dry-material preparation is increasingly used for water treatment. Grundfos can supply PLC-controlled, fully automatic systems to handle preparation and the reliable dosing of organic coagulants or poly-electrolytes.

Changing load conditions require a pumps system that can handle large flows at low head. Grundfos AFG flowmakers offer an optimum, energy-efficient solution for mixing in big tanks, creating a bulk-flow with an almost uniform flow-velocity and limited risk of dead zones. Where tank design doesn’t allow the use of flowmakers, Grundfos AMD and AMG mixers offer a robust design with corrosion resistant materials, easy service and maintenance, and trouble-free operation in difficult environments.

Grundfos can supply the specialist expertise to help meet your performance objectives, from the initial identification of needs, to the selection, installation, operation, and maintenance of the pumping solution. Grundfos commissioning agreements ensure correct installation and service agreements cover all eventualities, from routine maintenance to spare parts and pump audits.
