Jack's Making a Splash...
CPC is a proud sponsor of champion diver Jack Laugher. In his latest blog, Jack talks about his training and his recent gold medals in the World Series.
Jack's Blog: The start of my year.
Last year was the best year of my career so far and I knew it was going to be tough to follow it. I had a really good off season with a lot of training, learning and getting stronger and also had an amazing time out in Rio De Janeiro diving in the Olympic pool! Rio was a lot of fun and also an amazing experience, getting to grips with our surroundings for when the big moment comes next year!
The first competition of the year is the National Championships, which take place in February. I had learnt a new dive during the off-season and was extremely excited and nervous to show it off here. Training leading up to the nationals was looking really good and I was in a mentally and physically great place until one session when I felt something give in my arm. I thought nothing of it and carried on training which was a huge mistake as this injury put me out of action for 10 days with only just over 2 weeks to go before competition. I had done nerve damage from my neck down to my right arm and this meant my muscles wouldn’t activate, in turn causing me pain. This was a nightmare come reality for me as I wasn’t even sure I was going to be able to compete. Luckily with the help of doctors and the physiotherapists, I got to a pain level that I could deal with so I could train and compete. I managed to use my new dive; the 5156b (forward 2 1/2 somersaults, 3 twists piked) and I got 93 points on it, which was brilliant! The competition went smoothly despite my injury and I came away with two gold medals to start off the year with. Brilliant!
Our next competitions were the World Series. The World Series consists of 6 different competitions around the world in places such as China, Mexico and Canada! The first leg was 2 competitions, 1 in China, 1 in Dubai. After Nationals I had 2 weeks to recover and prepare for leaving to officially start my international season off. Training was still difficult with my injury not fully healed and sometimes having to cut sessions short because of the pain, but we did some good work. I learnt from the Nationals what my weaknesses were and my coach and I tried to work our best to rectify these mistakes.
We left for China at 5AM on a Monday morning and arrived at the hotel at 6PM Tuesday evening! The long journey wasn’t good for my body and I was sore for training on Wednesday, but with only 2 days until the competitions, I had to bite the bullet and get on with it! The first comp was the synchro competition with my partner, Chris Mears. The first international competition of the year is always scary as we are up against the best in the world and that’s always daunting. We put out a good performance but only managed a 4th place, narrowly missing out on a medal to the Germans. With my individual the next day there was no time to sulk. I had to be ready to go again for a full day only 10 hours later. I made it through my semi final, qualifying in 4th place overall. This was the first international competition doing my new dive and it was in the 2008 Olympic Beijing Water Cube. Great venue, but very cold making diving very difficult to do! Unfortunately I didn’t medal but it fuelled me for the next competition in Dubai.
We had an even earlier start to head to Dubai! Leaving the hotel at 3am felt like death to me! I slept all the way to the airport and we had an 8-hour flight to Dubai. I love Dubai because it’s so sunny and such a nice pool. Plus, my old diving coach now works there so it’s nice to see him once in a while. We only had 2 days of training before the competition so not much time to prepare. Training was going really well even though I was still carrying the arm injury that I mentioned earlier.
It got to our synchro competition day and we were a little bitter after our 4th place from Beijing. We did our best required dives since the Commonwealth Games and we were doing really well for our first three dives. On our 4th dive I dropped a little bit short and on our last, Chris went a little over on the 6th dive. We ended up 4th again, which was really horrible for us. New tactics next time I think.
My individual was up next and I was pumped after being only 6 points shy of my PB last time. In my prelim were the Chinese and a Mexican. I was fairly confident I could make the finals and with a score of 517 I sailed through with a PB by 0.5. With an amazing and steady performance I was filled with excitement for the finals later. After a very powerful session, the finals started. I opened up with my first dive and got over 90 points! The first time this has happened in a senior competition. I was off to a good start. I was calm and focused and I stuck to my routine. I didn’t know how well I was doing until I stepped on the board for my last dive to see my name, followed by “previous round rank 1”. That’s when it dawned on me that I could actually, not only medal, but win this competition. I felt the nerves and pressure to do a good dive and ended up doing the highest scoring dive on my list with my last dive to secure my first ever senior international win as well as a HUGE PB. I’ve never been so shocked and happy at the same time! To be a world series champion and knock the Chinese off top spot was such a great feeling and I’ll never ever forget it. I scored 564 points and I was only 8 points shy of the world record set in 2008 by He Chong. I still have things to work on back in Leeds but it is going to be an exciting year!
Thank you to everyone at CPC for your continued support and the “congratulations” messages I am receiving over twitter etc when I am away competing It is nice to know that I have your support whatever the result but hopefully I can carry on the success! I think now is probably a good time to mention that the water in Beijing could really do with a bit of TLC from you guys!
I hope you have enjoyed my blog and I look forward to keeping you posted on what happens in the coming months!
All the best,

Pool Water Treatment Advisory Group - Polyaluminium Chloride PAC Dosing
What is continuous flocculation?
Continuous flocculation is a process of binding impurities in the swimming pool water into larger particles which are not big enough to be trapped in the filtration system.
It is strongly recommended by the Pool Water Treatment Advisory Group and importantly it is a highly effective method of dealing with chlorine resistant infections such as cryptosporidium (a highly infectious organism that causes chronic cases of severe diarrhea).
Flocpac Super is the perfect product to be administered via the Flocdos + pump.
The product is ready to use and system is designed to take the chemical directly from its supply container.
The product is dosed at a rate dependent on the pool flow rate i.e. if a pool has a filtration flow of 100m³/hr the dose rate is 0.1 to 0.3ml/m³/hr. Therefore the dose rate should be 10-30ml/hr i.e. 240-720ml/day or 1.7 - 5 litres per week.
Flocdos - Installation
- one system require for each pool.
- no system should be fitted to the pools with high rate sand filtration.
- only for use with sand filters.
- injection of product should be pre-filter.
- injection point should be at least one metre from the filter inlet, and as far away as possible form the filter inlet.
- ideally, injection point to be no more than 1.3m from floor but at least located at a manageable height.
- auto controller sampling should be pre floc injection.
- injection runs should be sheathed and as short as possible.
- pressure switch should be fitted psot filter and set to operate when filter pumps go down of any reason.
- product FlocPac Super to be taken directly from carbuoy and not diluted.
Polyaluminium chloride (PAC) dosing
The Pool Water Treatment Advisory Group released the following new technical note in February 2014:
A PWTAG Technical note 24
Continuous coagulation with polyaluminium chloride has long been recommended by PWTAG – especially in the light of the threat fromCrytposporidium. Like all coagulants PAC works by extracting and then clumping together dissolved, colloidal and suspended matter. The resulting floc is then trapped on the filter.
This note clarifies the application and dosing rates for the various different grades of polyaluminium chloride being sold in the UK.
Filtration through a porous medium such as a sand bed is an efficient and cost effective means of reducing water turbidity. But sand filters are very limited in their ability to remove Cryptosporidium. Research at Swansea University for PWTAG in 2004 demonstrated the importance of coagulation in filtering out Cryptosporidium oocysts. Without coagulation removal rates in a single pass of a medium-rate filter were about 50%. This was dramatically improved, to over 90%, by dosing polyaluminium chloride.
PAC is directly and continuously dosed from the containers in which it is delivered at a rate of about 0.1ml/m3 of the circulation flow. (It is very important that it is not diluted with water as it will form a gel.) This must be mixed as evenly as possible throughout the water flow.
Where to dose
Following dosing, coagulation of pollutants happens quite quickly. Flocculation is a slower process, where the coagulated particles come together in flocs, so it is important that there is sufficient time before the water reaches the filter media. At least 10sec is recommended, at a flow velocity not exceeding 1.5m/sec. This can normally be achieved in the space in the filter above the filter media. But to ensure the best possible mixing, PAC should be injected as far before the filters as possible – but after the place where the sample for the chemical controller is taken.
How to dose
For a pool with a capacity of 450m3 (100,000 gallons) and a turnover period of 2 hours the circulation rate is 225m3 per hour. The PAC dosing rate for this pool would be 22.5ml per hour. This is a very small quantity (two and a quarter 10ml test tubes per hour) and is difficult to dose accurately.
Most chemical dosing pumps used for dosing the other chemicals used in swimming pools are not capable of adding this small quantity accurately and continuously. The most suitable type of dosing pump is a peristaltic pump.
Different grades of PAC
PWTAG recommends a normal dosing rate of 0.1ml/m3 of the total flow rate, which it has also described as 0.005ml/m3 as aluminium. There are now a number of different grades of PAC with aluminium concentrations between 9.5% and 18%. The concentration of aluminium is not the only consideration when selecting a grade of PAC to use. (If it was, PWTAG would be recommending the much cheaper alum – aluminium sulphate.)
Commercially available PAC products are characterised by their degree of basification – ie the concentration of hydroxyl groups (OH) relative to aluminium ions. PAC products can be in the range of 5%-65% basicity. As a general rule, the higher the basicity, the higher the polymer content and thus cationic charge density and efficiency. Higher basicity products have a lower aluminium content but are more efficient in clarification of water (ie turbidity/suspended solids removal). Because there is less aluminium content there is less aluminium in the backwash water. Furthermore, aluminium residuals are minimised.
The lower aluminium content products have a higher basicity, so the best advice that PWTAG can give is to use the same dosing rate for all grades of PAC, that is 0.1ml/m3 of the total flow rate.
1 PAC should be dosed as far upstream of the filters as possible, but after the chemical controller's sample point.
2 PAC should be dosed continuously using a peristaltic pump.
3 All grades of PAC should be dosed at a rate of 0.1ml/m3 of the total flow rate.

Commissioning An Outdoor Pool in Spring
Spring has sprung and that means it's time to start opening outdoor pools; here are a few hints and tips to help you. If you have any questions about your pool then please leave a comment below and we will be happy to help.
- Ensure that the pool water level is close to the top of the pool to give sufficient water to be able to vacuum to waste.
- Clean and remove winter debris cover and if possible allow to dry before folding up and packing away for the summer – if the cover has sustained any damage during the winter now is a good time to get it repaired so it is ready for the autumn.
- Re-commission plantroom equipment.
- With the multiport valve in the waste position vacuum the pool floor to remove any debris that has settled during the winter – keep an eye on the water level in the pool as it will drop while you are vacuuming.
- After vacuuming give the filter a good backwash and rinse, then set it in the filtration position and keep the filter pump running.
- Brush pool walls thoroughly to get anything ‘clinging’ to the walls into suspension so the filter can start to remove any debris.
- Test the pool water paying particular attention to pH, total alkalinity and calcium hardness – if there has been a lot of rain during the autumn it is likely that all the levels could be below the ideal ranges. Dose the pool with any products required to correct the levels.
- Shock dose the pool with chlorine to satisfy any chlorine demand and establish a chlorine level.
- Apply an algaecide, either a long-life or regularly dosed version.
- If the chlorine level is not too high then fit the solar cover and give it a good brushing if required to clean it.
- Keep the filtration system operating continuously for a few days or until the pool water is clear and clean. After a couple of days check the sanitiser, pH, total alkalinity and calcium hardness levels are where they should be after the initial chemical treatments, adjust as required to achieve the ideal levels.
Dealers: We have a spring showroom poster available that displays the typical products required to open a pool. Please ask for one on your next order.
A2 silver snap frames are also available.
