Hello @Samiya Kazi, Where in your waste water plant?    Where in your plant does this "filamentous insect as plant" start growing?   We have had success stopping the growth of this algae in natural swimming pools.     Does It look like "green cotton wool" clumps floating near the water surface?      We added our MONKO biotreatment powder which consumes nutrients faster than the algae.
