Flushing, Cleaning And Water Treatment Services

The following is work necessary for Pre-flush, Pre-commisioning cleaning and inhibitor dosing (including biocide in chilled systems) of LPHW and Chilled systems.

Water Treatment

The LPHW/CHILLED systems will be flushed with a cleansing agent, CT340. Then when all of the agent is removed a corrosion inhibitor HE H 600 will be added to the heating/chilled systems. The correct dosing levels will be attained and a report provided for your records (BSRIA Application guide 8/91).

• All requirements of COSHH regulations will be complied with during the chemical cleaning and chemical treatment.
• An Ivorine label will be permanently fixed adjacent to the dosing area stating the chemicals and dose quantity.
• A completion certificate will be issued when the above has been performed.

Sterilization (Chlorination)

• The mains water systems including the water storage tanks will be chlorinated in accordance with BS6700.
• The systems will then be flushed and the sterilization chemical will be introduced up to the correct chlorine concentration.
• The systems are then left for the correct period of time (indicated) whilst monitoring the chlorine level at intervals to ensure that the concentration is maintained.
• When the chlorination is complete and the chlorine in the systems has been neutralised a sample will be taken and tested for bacteria. This sample will be sent to the Public health laboratory which is a CPA Acredited Laboratory.

On completion of the procedure full certification will be given.
