Flocculation is an important part of all swimming pool systems which ensures the filtration of otherwise non-filterable particles and is particularly effective against disinfectant resistant protozoan such as cryptosporidium.
We would always recommend continuous flocculation in form of poly aluminium sulphate (PAC) a chemical which is dosed in very small quantities for 24hours, 7 days a week. A medium rate filter system (typically at leisure centres) with effective flocculation via PAC should remove 99% of the cryptosporidium oocysts.
At correct flow we can offer to retro fit PAC systems to most systems within the commercial sector, the chemical is dosed directly from the transport container.
PAC systems –
- Peristatic pump c/w foot lance
- Dosing hose and injector assembly
- Safety bund to store chemicals
As with all our equipment we offer total back-up with on-going planned preventative maintenance (PPM) and reactive support as needed.
