As water passes over rocks, phosphates are washed into the water. Phosphates are added to drinking water to prevent lead leaching from pipes and are often present in wastewater effluent. As phosphates are essential to life, high phosphate levels in water bodies will promote algal blooms.
Phosphates are widely used in fertilizers, so a shortage of these will have a significant impact on global food security. Phosphates come from rocks and are non-renewable, so must be recycled. Globally there is a drive to prevent phosphates from not being recycled from effluents and soil runoff.
The Photometer 7500 is Palintest’s top range photometer covering all major water quality parameters, with more than 80 test methods.
The Pooltest 3 combines testing for chlorine, pH and cyanuric acid, for quick assessments of water quality.
