Cleaning & Disinfection

Aqua Technologies’s qualified and experienced engineers carry out cleaning and chemical disinfection of Hot & Cold Water Storage Tanks and associated pipe works. The process follows the methods recommended in HSE’s ACOP L8 and BS8558 and involves draining and cleaning the tank to remove sediments, scale, sludge and bio-film before refilling and chlorinating the water to the required level. The treated water is distributed throughout the system and allowed to stand for a period of time before the chemical is neutralized. The entire system is then thoroughly flushed before being re-commissioned. Aqua Technologies also uses latest technologies like Silver Peroxide and Chlorine Dioxide for disinfection.

Pre-commissioning Cleaning

New pipework often contains debris leftover from construction which can cause corrosion, damage and encourage microbiological growth which will in turn cause severe corrosion, blockage etc. Flushing, chemical cleaning and system stabilization is required for heating, chilled and condenser circuits also. This work will increase plant efficiency and minimize downtime caused by blocked filters, strainers and abrasion in pump seals etc. When existing systems are found to be fouled by corrosion, scale or debris resulting from a lack of incorrect treatment, Aqua Technologies offer an in-line cleaning programme using non toxic chemical cleaning technology in conjunction with the flushing and inhibiting procedures used in pre-commission cleaning.

Open Cooling Water Treatment and Monitoring

In order to meet the primary objective, colling water treatment technology is concerned with the five basic problem area, which are:

• Scale Formation
• Corrosion
• General Fouling
• Microbiological Fouling
• Control of waterside conditions by the correct application of treatment and maintenance of necessary reserves.

We have a full range colling water treatment programme including monitoring and auditing.

Closed Circuit heating systems treatment

We carry out heating systems treatment for many commercial properties, hospitals, schools, and care homes across the country. This includes flushing, chemical cleaning, inhibitor dosing, water sampling and monitoring.

Closed Circuit cooling water treatment

With closed systems, there is normally minimal water loss and hence negligible concentration of the dissolved minerals. With these systems, the cooling of water occurs by means of heat ex-changers, refrigeration equipment or radiators. Closed systems are used typically in refrigeration chilled water or engine cooling systems. We have an effective treatment program for closed Systems.

Steam Boilers Treatment & Monitoring

The boiler system includes the feed lines, pumps, control gears, the boiler itself and the steam condensate systems.
We do a full range of boiler treatment for safe operation which includes:

• Pre-treatment plant
• Dosage and control equipment
• Chemical treatments
• On-site and laboratory analysis, reporting and guidance
• Inspection and troubleshooting
• Provide training to operators

Swimming Pool Treatment & Monitoring

We carry out treatment and monitoring for a number of swimming pools across UK. We use Chlorine, Chlorine dioxide and Silver peroxide for the disinfection of swimming pools. When we use chlorine as a disinfectant and an oxidizer at a pH value of 6.5 often, acid is added to lower the pH value. Chlorine kills pathogenic microorganisms that are present in the water. When too much chlorine is present, it can cause eye and mucous membrane irritation, as a result of chloramines formation. Lowering the chlorine concentration is undesirable, because this increases the water borne diseases. Regular monitoring and sampling is highly necessary for swimming pools. Aqua Technologies provide highly professional service as well as training to operators.
