Consuming h2o materials that are especially susceptible to unicellular algal blooms, and provides with reduced turbidity and superior colour normally see this page make use of DAF. Just after coagulation and flocculation processes, Your Domain Name water flows to DAF tanks where air diffusers around the tank bottom build high-quality bubbles that connect to floc leading to a floating mass of concentrated floc.
SPS contain the UK’s biggest and most varied fleet of DAF units available for employ the service of along with supplying long lasting installs. Our modular, mobile, plug-and-Engage in techniques are All set for speedy deployment and commissioning onsite.
