Membrane technology:
Membrane technology is an effective and modern technology for the waste water treatment which makes possible both nano and ultra levels of microfiltration. This technology isolates effectively particles, colloids and macromolecules, so that waste-water can be effectively purified and made re-usable worth even for drinking purposes as well as for other industrial usages. Membrane processes includes microfiltration, ultra-micro filtration, nano filtration, reverse osmosis process, electrolysis process, dialysis process, electro dialysis process, gas separation process, vapor permeation process, membrane distillation and membrane contactors.
Membranes are very expensive and if one allows the contaminant water to come in direct contact with the membranes the membranes can get chocked abruptly. Hence to protect the membranes and enhance its life, users of membrane technology often install pre filter systems supporting the membranes in order to isolate to a large extent the macro suspended particles from the waste. Such solid particles membrane removal technology by means of mechanical separation is known as pre filtration process or polishing filtration. These contaminants are separated or retained by this filter system while passing through a medium very popularly known as filter media. Element and cartridge would be either cleaned or replaced as per one’s requirement.
Filter Concept analyses the application requirement and designs the economical mechanical filtration systems. At the pre engineering stage, system designing process involves process calculation, system design calculation, process chemical compatibility etc. At the post engineering stage, filter vessels are manufactured as followed by ASME, involving a structured QC process of a series of quality check points and testing.
Range of filtration system for water treatment plants:
• Cartridge filters housing and it’s consumable.
• Bag filters housing and it’s consumable.
• Bucket or basket and strainers.
• Self-cleaning system: Scrapper type self-cleaning system, auto backwash type self-cleaning system, auto back flush type self-cleaning system, disc type self-cleaning system.
Benefits:
• Smooth and ease in operation.
• High efficiency filtration.
• Low running and maintenance cost due to unique design.
• High profitable for industries.
Stainless steel cartridges
Concerning environmental issue Ashok Prasad, Proposal Manager, Filter Concept Pvt Ltd says, “Filter Concept is always keen to provide environment friendly solution and with this prime objective we introduced stainless steel cartridges replacing the PP media. We are quite aware that PP materials are non-degradable and their disposal into environment has always been a matter of deep concern for us. They can neither be composed nor be left as it is to the time and whether conditions, as even after decades after decades they continue to remain same. Other option we looked into was to go for incineration which involves burning of those materials. This adds to emission and reduction of the crucial ozone layers and significantly contributes to global warming. Under worst circumstance, the fumes release dioxins which are one of the most lethal carcinogens known. As against PP, stainless steel is recyclable and reusable and completely eliminates the need to dispose the cartridges. Due to its reusable applications and cleaner properties, these filters have become very popular and are widely demanded in the industries. They are also easily being retrofit to the existing cartridge filter without having to modify the housing in any manner.”
