The elimination of liquid solids within wastewater treatment can be achieved through the use of liquid or powdered polymers; this is realised by the employment of polymer dosing and dosing systems.
Polymers are frequently specified in wastewater treatment to purify and treat dirty water and are used for clarification, thickening or dewatering applications. Essentially in wastewater treatment processes, polymers attract all fine particles suspended in a liquid to form larger groups leaving behind clear water. They do this by suspending solids and producing large fractions of solid materials through a process called flocculation.
Polymers are synthetic, organic flocculants available in three industry recognized forms; these being
Cationic Polymers: attract negatively charged ions in solution.
Anionic polymers: attract ions with positive charge in solution.
Non-ionic polymers: show a neutral behaviour in the solution.
The nature of the target particles, the properties of the liquid, including pH, electrical conductivity, hardness and added chemicals, determine the most effective type of polymer to use.
Our range of Polymer Make-Up and Dosing Systems
AllWater Technologies Ltd provides a wide range of compact, dilution and delivery units for polymer concentrates.
The Polymore System offers a unique and compact solution to your needs being a combination of polymer makeup system, dosing tank and distribution pump.
Mixers are able to dissolve polymer concentrate flows between 0,004 l/hr to 54 l/hr, with systems also providing
In-line mixing, ensuring that preparation of the solution takes place in a continuous flow.
A pressure regulating valve to stabilize pressure variations in feed water supply.
Polymer delivery by peristaltic metering pump, which can be controlled by a 4-20 mA signal.
Unique multi zone system to ensure effective mixing and activation of liquid polymer without creating inactivated polymer solution in the form of “fish-eyes” or “angel-hair”.
Large mixing chamber providing sufficient time for polymer activation, made from non- transparent material to guarantee that none of the activated polymer solution is destroyed by UV-light prior to dosing.
Transparent pipe on outlet to allow visual inspection of the diluted polymer solution.
As well as providing make-up and delivery solutions AllWater Technologies Ltd are able to offer a wide range of polymers to suit your requirements and are able to carry out tests on your waste stream to help assess the best product to suit your application.
A wide range of dosing pumps, accessories and spares from leading manufacturers such as Prominent, Lutz Jesco & Grundfos (Alldos) are also available for delivery of polymer and other chemical reagents.
