Alfa | Polyamide hydrocyclones Hydrocyclones enable to eliminate most of the heavy solids suspended in water. The main application is treatment of sand-loaded well-water. Built in thick molded polyamide, these hydrocyclones are not exposed to the effect of corrosion which occurs on carbon steel hydrocyclones and have a longer life span. Drain valve. A valve enable to drain the tank easily. Unmountable hatch. on each side of the tank, a hatch enable inside access. Fast closing system. Fast closing flanges system, for an easy mounting an unmoun- ting . Tightness through 2 o-rings. Drain Suspended solids drain. To be connected to sewer or outside. OUT. Purified water IN. Water to be treated Polyamide body. Body in thick molded polyamide. HOW IT WORKS Tank. The tank is big enough to be able to collect severals kilograms of solids. Water enters the hydrocyclone on the side. It is accelerated and whirls in the conical part. Purified water goes out through the center, to the top. Suspended solids fall in the tank. Tank is drained by opening a valve.
