Flocculation and filtration in the supply of potable water

Effective removal of solids for optimum water quality

Flocculation and filtration are amongst the key steps in potable water treatment. They remove turbidity, suspended matter and dissolved particles from the water through the use of specific chemical and physical processes. Upstream coagulation, precipitation or flocculation vastly improves the effectiveness of any subsequent sand or membrane filtration.

Meter flocculants in a targeted fashion – with systems from ProMinent

Precise ProMinent metering systems allow for the optimum use of liquid and solid flocculants (e.g. ferrous and aluminium salts) as well as flocculation aids (like polymers). They cause tiny particles to come together to produce larger flakes, which are easier to filter out. This also helps to efficiently remove oxidation products from (pre-)oxidation.

Filtration technologies: Traditional or ultra-modern

Various filtration methods are used as required:

Sand filtration for mechanical pre-filtration
Ultrafiltration Ultrafiltration is a membrane process which is increasingly used in water treatment to separate ... more in the glossary and membrane filtration In water treatment, membrane filtration is the process for removing particles and salts in the water ... more in the glossary for the finest levels of retention

These technologies reliably remove particles, micro-organisms and dissolved substances from the water.

Additional option: Activated carbon to adsorb trace elements

Powdered activated carbon can also be used upstream of filtration. This specifically binds natural organic matter (NOM), fragrances, flavourings as well as microscopic residue, e.g. that from drugs or pesticides.

Suitable products - Flocculation and filtration in the supply of potable water

Storage Tanks

Useful capacity 500 l- 50,000 l, indoor and outdoor installation

Our plastic storage tanks guarantee compliance with statutory specifications taking into account country-specific approvals, which regulate the production and operation of systems for storage and metering of environmentally-hazardous substances.

Ultrafiltration System DULCOCLEAN UF

8 – 75 m³/h filtrate output

Ultrafiltration system DULCOCLEAN UF reliably and safely uses membrane technology to remove turbidity, particles and microbiological contamination.

Eccentric Screw Pump SPECTRA

Capacity range 2.4 – 12,000 l/h, 12 – 3 bar

The eccentric screw pump SPECTRA meters liquid polyelectrolytes in concentrated and dilute form. It can be used, for example, in wastewater treatment or sludge dewatering.

Tomal^® Big Bag emptying unit

Emptying of Big Bags up to 1,000 kg

This emptying unit is used to accommodate and empty Big Bags weighing up to 1,000 kg. The Big Bags are suspended in the frame with the aid of a lifting cross bar. The 30-litre powder storage tank is used to transfer the powder into a feed unit.

Tomal^® metering system for powdered active carbon (PAC)

5-50 kg/h of dry PAC with a re-dilution of 3-5 m³/h and a final concentration of max. 1%

Conventional wastewater treatment cannot adequately remove trace elements, such as medication or cosmetic residue, from the wastewater. This is particularly effective using the complete system for the precise metering of powdered active carbon (PAC).

Diaphragm Metering Pumps

Diaphragm metering pumps enable precise dosing of liquids and are used in water treatment, the chemical industry, and food production. They are characterized by reliability, durability, and versatility. ProMinent offers customized solutions for different requirements and processes.
