Case Study
Blue-Green Algae Lake

Problem
- Many inlets of wastewater from neighbouring factories and agricultural discharge causing drop in dissolved oxygen and increase of blue-green algae growth in many parts of lake
- In certain months of the year, there is rapid growth of the blue-green algae causing disturbance to the aquatic environment of the lake and displeasure with the community
- Blue-green algae has an average depth of 10cm to 30cm at surface water of lake at various locations. Bad odour also detected.
Solution
- Test conducted by taking sample lake water and mixing WaterRejuvenate in.
- Within 30 minutes, blue-green algae can be seen to be coagulated at the surface
- Within 2 hours, height of the blue-green algae is seen to reduce
- Within 24 hours, further reduction of blue-green algae, drop in COD and BOD
- Within 48 hours, all blue-green algae are digested and water shows clear & transparent
River Water Treatment


Problem
- River water contain lots of algae and waste as there are many pig farms along the banks of river
- River water contain animal, organic waste, chemical waste and pesticide


Solution
- Treated water by mixing WaterRejuvenate into river
- On treatment, impurities start forming and coagulation occurs
- Within 2 to 3 days, water start clearing up
- Within 1 week, algae is reduced and water is more clear
- After 1 month of treatment, river water has no algae and water is clear once again
Solar Factory Waste water treatment

Problem
- Solar Panel factory has been filtering their waste water from washing of the solar panel but the cost of changing their filters are rising
- Due to the size of particles of the solar panel in the waste water, filters will have to be changed more regularly due to the ineffectiveness after particles are trapped in the filters.
- Factory has been having issues on duration of changeout of filters per year
Solution
- Testing was done to proof that WaterRejuvenate is able to coagulate all the impurities in the water
- Test shows that WaterRejuvenate coagulated all the particles
- From the test, the live implementation was done by creating a sedimentation tank station before the filtration, which takes away 99% of the particles that are damaging or affecting the filtration system
- Overall total cost of changeout of Filters reduces by 70%
