Effectiveness of Ceramic Ultrafiltration for SWRO Pre-Treatment
Desalination is becoming vital for securing a strategic and sustainable source of water around the world, and membrane-based seawater reverse osmosis (SWRO) desalination is a popular desalination technology. An effective pre-treatment process for SWRO impacts the performance and costs of the overall plant. Pre-treatment processes for SWRO are either conventional technologies or make use of […]
Lessons Learned During Four Years of Operation of a Ceramic Membrane System for Drinking Water
The drinking water source for many municipalities is a lake or reservoir that is at a much higher elevation than the treatment plant, and the water must first be stored before pumping through the treatment system in order to prevent over-pressurization of the equipment. One such facility is the Basin Creek Water Treatment Plant in […]
Ceramic Membrane Basics and a Specific Application Treating Stillage from Bioethanol Production
Atech is manufacturer of ceramic membrane, which provides unique advantages over polymeric membranes, such as greater mechanical strength and higher chemical and thermal resistance. The two main membrane types – tubular and flat sheet – each have their own advantages: typically, tubular membranes are more accessible and flat sheet membranes treat higher solids. Both types […]
Inorganic Membranes – Diverse Materials of Construction Enable a Wide Range of Applications
Design, construction, and operation of inorganic microfiltration and ultrafiltration membranes are discussed. The topics include materials of construction used for the membrane support and active membrane layer (silicon carbide and metal oxides). The physical and chemical properties of membranes manufactured using the various materials will be presented for contrast and comparison. The comparisons include advantages […]
Advanced Surface Water Purification Without Advanced Complexity
Purification of surface water is challenging as a result of the numerous contaminants and the high variability of those contaminants in surface water. Seasonal variations and weather changes add to the complexity of designing step by step unit processes to address those fluctuations. Accordingly, traditional design approaches have incorporated the kitchen sink approach with extensive […]
