The increasingly use of membranes in recent years has been prompted by 2 main drivers; Membranes costs - falling membrane material and manufacturing costs, improvement in membrane quality and ease of production, installation and operation Water costs and resources - increasing price of water, decreasing resources, increasing costs of pretreatment for industry and residential use, stricter legislative controls in many areas
Advantages of using membranes |
| Reliable | Production of consistently high quality product water | Compact | Low land take and equipment requirement low | Robust | Stable operation in treatment of many types of wastewater | Economic | Effluent can be re-used for irrigation, flushing, pretreatment for RO | Reduction in disinfection costs | | Reduction in sludge production and thus disposal costs |
| Flexible | Flexibility for future expansion | Convenient | Rapid set up, simple installation, programme saving |
