1-2.Decrease of Fresh and Clean Water Resources
6
Leading to… (1) Lack of water at dams and rivers (2) Contamination of Fresh River Water by Sea Water due to low flow
pressure from river side makes Industrial Water salty
1. Climate Change
2. Less Rain
3. Decrease of
river water flow

Q: What can we do??
A: The possibilities are… Finding New Water
Resources
-Water well drilling
-New intake from river/spring
-Produce fresh water from sea water
Reuse of Used Water
-Water treatment for non-human use
and for human use
MBR System :
MBR (Membrane Bio-Reactor) System: - To Produce Water from Sewage with the combined technology of Bio-chemical process and Membrane technology to be re-used as intermediate water, such as irrigation, flush water etc,.
1.4 Introduction to Hitachi’s RO and MBR
8
RO System
SWRO (Sea Water RO Desalination) - to produce high quality freshwater from seawater for human and Industrial use. BWRO (Brackish Water RO) - To produce high quality freshwater from salty ground or surface water for human and industrial use.
HITACHI offers the State-of -art RO & MBR technology for Water Production Solution
MBR +RO Solution :
MBR-RO (Polishing RO) – To produce Clean and high quality freshwater from Sewage with the combined technology of Bio-chemical process, Membrane and RO technology to be widely used as high quality freshwater for human and industrial use. etc.
