Appropriate pre-treatment to the feed stream is essential for success of the membrane system and hence given utmost priority while designing a membrane plant. Clariflocculator, HRSCC, dual media filter, tube settler, PSF, CF, specially designed cartridge filter along with suitable dosing and back washable UF are used.

GMS provides following processes to make feed water suitable for the downstream processes :

• Centrifuge System
• Clariflocculator
• HRSCC (High Rate Solid Contact Clarifier)
• MMF (Multi-Media Filter)
• PSF (Pressure Sand Filter)
• ACF (Activated Carbon Filter)
• Cartridge Filter with Housing
• Bag Filters with Housing
