The principle explained
All the pre-treatment, reverse osmosis and electrical and pumping equipment is housed in 40 foot containers located on a flat surface close to the coastline.
The containers are connected by pipework and electrical cables. Three tanks are required for intermediate water storage between processes, and seawater inlet and brine pipelines are installed and connected to the desalination equipment. A delivery pipe takes the drinking water to the client's water network.
Sufficient pumping capacity is installed to ensure the necessary water pressures.
Redundancy is built into the system to allow for maintenance and shut downs.
Advantages
The advantages of the SSI onshore modular desalination plant:
- High-volume, low-impact solution
- Can be all be employed tactically to deal with water crisis
- Can produce over 20,000m3 of fresh water per day
- Can be fully operational in around 8 months
- Costs can be shared by a number of parties
- Has potential for minimal ‘footprint’ and full site clearance post-contract
- Responsible and environmentally-friendly disposal of brine
- Environmental and building permits can be obtained more rapidly due to short term nature of the contract
- Negotiable contract periods
- Can be employed as interim solution
- Pipeline infrastructure can remain for potential future use
Basic timelines
From signing of contracts:
Month 1 – Land allocated and local planning consent granted, and key equipment ordered
Month 4 – Lay offshore pipelines
Month 5 – Install onshore pipelines
Month 6 – All modular desalination plant installed
Month 8 – Commerce water production further to extensive testing
