​Products in action

Many pools in both soft and hard water areas, have successfully changed to hth® Calcium Hypochlorite for the unique benefits and savings that it brings. With a range of products & pack sizes to suit all pools and any plant room situation, hth® is widely used - from the smallest spa pool and water play feature, to large commercial rafting and kayaking complexes.

ELECTRO-CHLORINATION CONVERSION

A well known health and sports complex in Leeds, UK, successfully converted from an on-site Electro-chlorination (salt) generation system to  hth® Granules dosed via a pump and tank, resulting in:
  • saving of 50% on pH correction costs
  • 86% reduction in TDS levels
  • utility bills reduced
  • maintenance call-outs reduced to twice a year

THE PROBLEM
The site had a number of issues with the salt system keeping up to the chlorine levels required, so a second unit was installed to try and produce enough chlorine to meet the pool’s demand. Throughout the next 6 years the site had many issues...
  • Extremely high total dissolved solids (TDS) levels, with an average of 5000 mg/l
  • To try and keep TDS under control, the site had to complete 3 backwashes per week, resulting in large gas and water bills.
  • Severe corrosion of the metal fixtures and fittings around the plant room
  • Salt stalactites coming from the plate heat exchanger pipe connections
  • Precipitation of salt and corrosion around the filter lids
  • Customers complaining of salty tasting water
  • Pool water with a green tinge that was not inviting to swimmers
  • A high usage of sodium bisulphate as the pH correctant
  • Filter valves were replaced annually as the corrosive nature of the pool water was disintegrating them
Following a comprehensive plant room survey and full written report by the Technical Services team form Lonza, the site agreed with their recommendations of a simpler system that could address the issues listed above. The survey highlighted the amount of electricity being used by the salt system, the amount of gas and water being wasted as well as the damage the salt was doing to the plant room systems.

THE SOLUTION
​A 500 litre pump and tank system was installed to utilise hth® Granules.
Benefits of conversion:
  • Total Dissolved Solids reduced to 700 mg/l, with a much reduced dilution rate being required
  • Only 1 backwash required per week - electricity and gas bills reduced
  • Water no longer corrosive, leading to fewer breakdowns on metal parts of the pool plant room
  • Customers have commented on a noticeable improvement in the air and water quality
  • No need to purchase calcium flake and sodium bicarbonate
  • A saving of 50% on the pH correction bill
  • Expensive maintenance call outs reduced to once every 6 months compared to once every 2 weeks.

WHITE WATER RAFTING FACILITY

hth® Calcium Hypochlorite proves to be a success - not just in swimming pools but in this (appx. 42,000m3) man-made Kayaking and Surfing facility in the Middle East. Changing to hth® from a lesser quality of chlorine sanitiser resulted in:
  • Clarity of water
  • Control of algae
  • Reduced chemical consumption
  • Fewer annual deliveries
  • Little maintenance required
