nir-vana innovation network

This is an offer from a Czech engineering and technological company, operating worldwide and focused on intelligent membrane systems. The company designs, manufactures and implements their own comprehensive technological solutions to treat and process water in various industries. One of their solutions are ultrafiltration frame units designed to efficiently clean water from solids, bacteria and viruses but also to reduce its turbidity. As for their construction, the units are very compact and also modular, allowing wide variety of configurations without changes in the basic design. Therefore, the units can be deployed in diverse configurations and places. Proposed unified capacity series can operate in ranges from 0,5 m3/h up to 30 m3/h of feed, depending on purpose and feed solution. Their ultrafiltration frame units overcome conventional filtration methods in their efficiency and in combination with pretreatment and post treatment processes, forms a modern technological system for water treatment and recycling. Examples of application: - Water pre-treatment before reverse osmosis plants - Production of drinking water - Preparation of irrigation water - Pool water filtration - Recycling of wastewater from sand filter cleaning - Process water treatment - Recycling of wastewater treatment plant effluent – tertiary treatment of wastewater The basic configuration includes: - Main filtration frame – contains the feed pump, preliminary filter, ultrafiltration membrane modules in dead-end operation mode, piping and fittings, sensors, cabinet with main control panel - Backwash frame – contains the backwash pump, product accumulation tank, piping and fittings, sensors Available extensions: - Buffer tank for accumulating feed water with water level sensor - Pre-treatment of feed water – pH, disinfectant, oxidizing agent - In-line coagulation - Chemically enhanced backwash (CEB) - Automatic Forward Flush – cleaning of membranes in cross-flow mode - Automatic testing of membrane integrity Smart operation of the units: - Self-learning software set to optimize operating parameters based on real-time data evaluation, maximizing recovery, minimizing operating costs, prolonging lifetime of key components - Electronic service book - Continuous remoted surveillance of technology operation and condition Limits of operation: - Power supply: 400 V, 50 Hz - Turbidity: max 300 NTU - TOC (Total organic carbon): max 40 mg/l - TSS (Total Suspended Solids): max 200 mg/l - pH: 5-10 (1,5-12,5 for CEB (chemical enhanced backwashing), CIP (cleaning in place) ) - Water Temperature: max 40 °C - Cl2 (chlorine): max 3 mg/l - Recovery: up to 98%
