Welcome to the research group of themis sapsis!.In the stochastic analysis and nonlinear dynamics (sand) lab our goal is to understand, predict, and/or optimize complex engineering and environmental systems where uncertainty or stochasticity is equally important with the dynamics.We specialize on the development of analytical and computational methods for modeling high dimensional nonlinear.
Chat Online1.Types of sand filter the use of sand and gravel as filter media for water supplies can me split into three basic filter types: slow sand filters, rapid filters and roughing filters.Apart from desalination and reverse osmosis, slow sand filters are perhaps the most effective single treatment for purifying drinking water supplies.They are.
Chat Onlinefiltration.Most rapid sand filters contain 24-30 inches of sand, but some newer filters are deeper.The sand used is generally 0.4 to 0.6 mm in diameter.This is larger than the sand used in slow rate filtration.The coarser sand in the rapid filters has larger voids that do not fill as easily.
