Why did the Rio Olympics pool go green?

By now many of you will have seen images of the green diving pool at the Rio Olympics, but what made the water turn from crystal blue to murky green?

Nobody knows for sure but it seems likely that the Rio Olympics pool maintenance team ran out of chemicals to control the pH of the water which resulted in an algal bloom turning the pool green. To prevent the same happening in the water polo pool, the maintenance team have dosed high levels of chlorine into the pool, which is now causing issues for the water polo teams.

The incident would have been prevented with the use of an online controller such as Pi’s AquaSense swimming pool controller. Plus if the chemicals had ran out, such a system would have gone into alarm and enabled the maintenance team to prevent this from happening.

Pi’s AquaSense measures pool pH and chlorine levels and controls these with chemical dosing. The AquaSense can also be accessed remotely over the internet, enabling data, alarms and setup information to be sent directly to your computer via a 2G/3G modem or via a TCP/IP Local Area Network (LAN). Maybe the Rio Olympics pool maintenance team should have purchased a Pi analyser?

Shanghai Lim M & E Co. Ltd take Pi’s new controllers to Aquatech China

Pi’s Shanghai based distributor Shanghai Lim M & E Co. Ltd attended Aquatech China, and exhibited Pi’s new controllers and Pi’s sensors as a part of their stand.

Pi’s two new controllers, the Version 3 CRONOS® and CRIUS®, bring an extremely capable set of electronics to the water quality analyser market introducing a number of new features including;

  • Mobile phone style intuitive navigation,
  • Proactive maintenance warnings on all sensors,
  • 20 individual security passwords with flexible permissions,
  • State of the art “group” datalogs for ease of export and analysis in a spreadsheet.

Shanghai Lim M & E Co. Ltd have started supplying Pi’s third generation controllers in China, specialising in ozone analysers and pH meters.

The event held over three days from the 15th June, is the largest international water trade show in China for market leaders in the process, drinking and waste water industries.

Pi welcomes its new Quality, Health and Safety and Environmental Impact Co-ordinator

After an extensive but enjoyable interview process Chantelle Greenhalgh was selected from a strong field of candidates and took up her new position on Monday 25th April.

When asked what drew her to the role, Chantelle said “After a long period of continuous employment with the same employer, I felt like I needed a challenge so I’ve done a few fixed contract roles until I found the right role for me. Looking after the Quality, H & S and Environmental aspects of a friendly, technical manufacturing company feels right for me. I will be able to make a real difference to this great company and can play my part ensuring that Pi’s customers get exactly what they need first time and every time. The technical nature of the products and applications will keep me on my toes and its great to be part of a team of such committed professionals.”

Mike Riding, Pi’s Managing Director referred to the recruitment process, “Finding the right people for the right role is probably the most important job that I do here at Pi and I am particularly pleased that we have been able to attract a candidate of Chantelle’s calibre. Not only am I confident that she will do an extremely good job for Pi, looking after and developing the internal systems that we rely on, but I think she will bring a new dimension to the team, providing a new outlook and new ideas to challenge the status quo. I am looking forward to working closely with Chantelle.”

Pi continues to expand and is currently recruiting for extra applications and engineering talent to join the sales team, and also another scientist to work in the Development department.

Coagulation Control for Midleton near Cork, Ireland

Coagulation control is essential for the production of safe drinking water and Irish Water and Cork County Council are investing in the latest technology at Midleton Water Treatment Works near Cork, Ireland.

An automatic coagulation control system from Pi comprising of a central controller, UV254 monitor (for measuring the organics in the water), pH sensor (for raw water and coagulated water) and a Streaming Current monitor (to measure the charge post coagulation addition) all connect to a central controller with a simple and intuitive HMI (display and buttons).

From the controller the coagulation controller automatically uses one of the measurands to control a dosing pump that pumps more or less coagulant depending on the results from the measurement.

The controller allows the operator to easily and simply change the measurand on which the coagulant is based, so for example when the organics in the water are dominant it may use the UV254 measurement to control coagulant. When it rains and the nature of the raw water changes (for example the turbidity goes up) it may be more appropriate to change the coagulant control to be based on the raw water turbidity. Currently such changes would be done manually although in the future, as more information is available from the plant, the process can be automated.

Coagulation control systems in the past have either been based on a single measurand, making them unreliable when the raw water changes, or with multiple variables feeding into a complex algorithm, making them costly and unwieldy as they are difficult to understand and manage.

Pi’s solution is to have multiple single measurand control systems, all in the same analyser,  which can be selected […]

New Analyser Controllers from Pi

The latest controllers from Pi are now complete and available for purchase from your local distributor. Pi has been working on the new CRONOS® and Version 3 CRIUS® for nearly three years and they bring a new level of functionality, flexibility and affordability to the analyser, controller market.

The two new controllers bring an extremely capable set of electronics to the water quality analyser market introducing a number of new features including;

  • Mobile phone style intuitive navigation,
  • Proactive maintenance warnings on all sensors,
  • 20 individual security passwords with flexible permissions,
  • State of the art “group” datalogs for ease of export and analysis in a spreadsheet.

When asked what new feature he was most proud of, Pi’s Development Director Dr. Craig Stracey referred to the underlying code structure, “The way we have written the code for this latest version of Pi’s analyser family means that it is extremely robust, upgrades easily, is very intuitive to use and looks great!”

When asked how his customers were receiving it, Pi’s territory manager for the Far East Dr. Rob Paramore commented “They love it! It’s very easy to use for them and the operators, yet it has a whole bunch of really great features. The PID control is superb and there are some great features like the downloadable service file which is a human readable file with every setting on the analyser recorded. It’s fabulous for help with service or setup issues and is great to have as a backup. They’ve been really well received.”

The new CRONOS® and CRIUS® have now been shipped all over the world and are fully equipped with extensive I/O, datalogging and PID controls. A world beating cloud based remote […]
