Algae problem solved...
at Gold Coast lake
» The lake on Macintosh Island Park in Surfers Paradise was one of the problem areas. Algal growth, turbid water with zero visibility and water staining were spoiling the lakes attraction.
Council had implemented several measures but were unable to provide a viable cost effective solution.
After being made aware of the benefits which the Care-Free Conditioner offered it was decided to install a 150mm unit into the lakes re-circulation line.
During the next few weeks the "problems" were clearly fading away. The algae disappeared, the staining stopped and the water cleared so dramatically that you could see the bottom of the lake!
The works manager, Mark Bartlett said, "The only regret we have is that we did not paint the white return line on the bottom of the lake because the water is now so clear that the pipe is very noticeable."
As you can imagine the Gold Coast City Council is pleased with their investment.

Care-Free excels for Cootamundra Shire Council
In 2002, the Cootamundra Shire Council opened of one of the most advanced effluent treatment plants in New South Wales.
Knowing that many people would inspect their innovative plant in the years to come, they were determined to use the best technologies available.
Perhaps that is why they chose to install a 100mm Care-Free Water Conditioner.
According to the Chief Engineer, the Care-Free has been a great success. The parks and gardens irrigated with the treated effluent water have never looked so green and lush.
This is especially impressive when you consider the drought, the very hot summer and the 1,100mg/l salty effluent water.

Effluent irrigation problems solved...
saves golf club $10,000 p.a.
The Gundagai Golf Course uses effluent water to irrigate. However it caused a $10,000 annual maintenance problem. Every sprinkler on the course had to be hand cleaned every two weeks to remove blockages. Injection systems were considered but were too costly to maintain.
The Care-Free Water Conditioner provided a cost-effective solution to their problem and cost a fraction of the price of alternatives.
Results:
• No blockages
• No algal growth
• No chemicals required
• No salt build up in soil |

Mr. Keum Lee Seok, president of Bosung Care-Free, which specializes in water purification system, made a special suggestion to Golf Journal. The company was scheduled to have a testing of their water purification system at the KRA (Korean Racing Association) Kwachun Racing Park for about a month starting from October 13, 2005, and he wanted us to do an exclusive coverage of it.
Kwachun Racing Park is a comprehensive entertainment center where people enjoy horse racing as well as beautiful scenery and amenities. It can be a place for a picnic for preschoolers and families and various events such as traditional wedding, sports events for companies and groups, live performances and horseback riding.
October 13
The company installed the water purification equipment today and started to run it. As we were briefed, the pond was covered with a thick layer of green algae and the water was so murky that we couldn’t even see the fish in the water. Furthermore, the fishy smell was coming out of the water, making it impossible to enjoy the beauty of the surrounding and the pond itself. A preschooler at the park said, "Teacher, the water in this pond looks like dead water." |

October 15
Today is Saturday and a lot of people gathered by the pond for a traditional wedding.
At the Racing Park, horseracing is held on Fridays, Saturdays and Sundays, and an artificial waterfall and a fountain are displayed at the pond only on Saturdays and Sundays.
A thick color of green algae is clearly visible even from the falling water, bubbles float over the surface of the pond, and a fishy smell is everywhere.

It looks like a firm leased the playground at the Racing Park for a day and has a fall sports event.

October 22
It’s the tenth day since the installation of the Care-Free system.
The amount of green algae seen from the waterfall and the fountain was clearly decreased and the fishy smell has been completely gone. However, the color of the pond still looks the same...
October 25
Green algae in the pond have been evidently decreased and the movement of the fish is livelier than before. A ranger at the park was amazed and
said "It’s the first time that I can see the fish so clearly, and the fishy smell that was here during the summer has been gone." It’s been warm, but
yesterday’s rainfall turned the air cooler. The colors of autumn leaves around the pond look lovely. |

It was early in the morning, but Mr. Lee was very excited already. He said that the water had become clear and even the fixtures at the bottom of the pond could be seen. He was getting visible result after 17 days since the installation of the Care-Free system. But a staff member at the Racing Park warned not to be 100% sure yet. It might be a drop in temperature that caused the decrease in activities of algae.
It made us wonder...
November 4
Now it’s November. The condition of the pond dramatically changed. We can see the bottom of the pond very clearly. The golf balls that we threw in are also clearly visible. Autumn leaves keep falling onto the transparent pond. |

November 11
Today is the last day of testing of the Care-Free system. The color of the water in the pond looks natural as if it had got a new life.
Only to see if the drop in temperature affected the change, a staff member of the park, Mr. Lee and the reporter of the Journal visited college campuses in Seoul and Kyongki-Do.
And we all reached the conclusion that this project has been a great success. Regardless of the drop in temperature, the ponds on the campuses were at the condition similar to that of the pond at the Racing Park before the installation of the Care-Free system. We sent the water samples that were taken during the testing period to a lab and had them analyzed: the degree of murkiness decreased from 8.5 to 0.7, the chromaticity from 15.6 to 1.7 and the SS (floating particles) from 43.6 to 8. These data showed the results consistent to what we witnessed. |
