Function

the PolySeries of Polymer Preparation Units, has beenspecifically designed to provide effective solutions to theneeds of Water treatment Customers and offers a completerange of polymer batching and metering systems.

the polymer preparation unit is designed to automaticallyprepare polymer solutions which are used as coagulants forthe eventual removal of suspended particles in the watertreatment processes of a number of industries fromswimming pool maintenance through to the various stagesof waste water treatment.

the PolySeries can use polyelectrolyte in either powder orliquid form and is mixed with water. the polyelectrolytepowder is dosed from the storage hopper using a shaft lessscrew feeder with an integrated lump breaker, into thewetting and mixing cone, in proportion to the water loadedin the tank. this special feature allows to carefully controlthe amount of powder used, optimising the process andreducing over consumption.

Fed by gravity, the prepared mixture falls into the firstpreparation tank and then passes through the traps into thematuring and batching tanks. these tanks are equippedwith stirrers, which may also be present in the batchingtanks. the volume of the deposits and the continuousaction of the stirrers ensures that a homogenous mixture isobtained and that the retention time is suitable for perfectdilution. the electrical control panel ensures total systemautomation, guaranteeing correct preparation and the rightbatching.

Polymer Preparation Unit

the preparation tank is divided into three sectors: dissolving V1, maturing V2 and storage V3, interconnected by siphons that forma perfect flow between the tanks necessary for the formation of a top quality solution. the polyelectrolyte from the dosing unitcomes into contact with water, which is sprayed from a nozzle that ensures uniform dispersion.

the water/polyelectrolyte mixture then drops into the tank belowwhere the dissolving phase begins. in this first, dissolving sector V1, aslow agitator keeps the contents of the tank moving ensuringthorough homogenization of the solution. the siphon transfers thesolution to the maturing sector, V2, where another slow agitator keepsthe solution uniform until maturing is complete. then the solution istransferred to storage sector V3 from where it can be transferred foruse.

the level switches installed in this sector, control plantautomatic functions:

High and normal level switch when the solution reachesthe high level, this switch stops the powder dosing unit andcloses the water inlet solenoid valve. in the normal levelposition, it enables the dosing unit to function and opens thewater solenoid valve.

Low level switch when the solution falls to minimum levels,this switch stops the dosing pump and sets off an alarmindicator on the electrical switchboard.

BenefitsUsing the PolySeries systems provides the following benefits:

n Considerable savings in terms of polymer usage and running costs.

n Precision in the preparation and batching stages, optimising the processes.

n Space saving and system centralisation.

Using polymers and flocculants considerably facilitates the processes of removingparticles and solids suspended in liquid in the following applications:

n treating potable and industrial processing water.

n Purifying waste water.

n treating sludge, in order to improve the performance of centrifuges and filterpresses.

n Processes for the paper, chemical, petrochemical, mineral processing, canningindustries.
