Flocculant Dosing Systems

Flocculant dosing systems use a dry powdered concentrated form of polyaluminium chloride (PAC) that can be diluted down to produce large quantities of liquid PAC for dosing and chemical water treatment. Gaffey Technical Services supply dinofloc Activ concentrate, which is suitable for soft and hard waters and promotes rapid flocculation.


How do flocculant dosing systems work?

Flocculant chemicals encourage unwanted small particles in the water to bind together as larger 'flocks' that can then be easily filtered out. Using dinofloc Active Concentrate, this can be done very quickly at pH levels of 6-8 using just 2kg of the dry chemical diluted with 33 litres of water. In hard water areas it is sensible to dilute with a smaller amount - around 30 litres, to control the pH of the diluted mix - but the dosing rate can also be reduced to compensate.

The liquid solution is then dosed continually into the swimming pool/water feature treatment plant and the resulting flocks are directly filtered out as they form and are captured in the filtration system. Slightly higher dosing rates can be used in where higher organic loading of the water occurs, and faster dispersion can be achieved by dosing the liquid PAC close to the suction intake of the circulation pump.

Where is this type of dosing system used?

Flocculant dosing systems provide continual results as rapidly formed flocks are mechanically filtered out of the water, making them a good option for round the clock pool water treatment in high-traffic commercial pools and spa pools, and in water features/theme parks where the aesthetic quality of water is important.

What are the features of Gaffey's products in this range?

The iFLOC Xact precision dosing pump offers the necessary accuracy and continuous dosing required to achieve excellent results. dinofloc Activ is a concentrated product which eliminates the need for costly, heavy liquid chemical deliveries (mainly water) and dramatically reduces the storage space required for PAC product. Each box contains four 2kg containers, which can be diluted down to 33 litres each (30 litres in hard water) for a total of up to 132 litres of liquid PAC dosing chemical. The premium quality of dinofloc Activ means there are no residues or impurities in the liquid flocculant, resulting in a clear, clean dosing solution.
