Seawater desalination, which is the production of fresh water from saline water, is a water treatment technology used for fresh water resources utilization. Reverse osmosis (RO) desalination is a reliable technology which produces large amount of fresh water with relatively low costs. With the desalination technology, SafBon guarantees the stable supply of potable water and industrial water to municipalities, power, oil & gas, mining, resorts and other industries.
Over the years, SafBon has been active in the field of desalination. Since SafBon has forayed into the desalination business field, the SafBon desalination expertise, experiences and technologies utilized has improved tremendously. SafBon has enhanced desalination capabilities which are very cost efficient. Furthermore, SafBon utilizes membrane desalination technologies with SafBon own dissolved air flotation (DAF) and ceramic flat membrane (CFM) products which provide extremely good protection of the RO installation against organic fouling and scaling.
To minimize the impact of membrane fouling, which reduces membrane performances and lifetimes, pre-treatment process is required. There are several types of fouling process, including colloidal fouling, inorganic salt scaling and bio-fouling. This is also affected by the plant location, the intake seawater type and the seasonal variations. As a result, the raw water may contain significant amount of suspended solids (SS), colloidal pollution and dissolved organic pollution.
The pre-treatment process SafBon uses includes DAF and traditional coagulation, sedimentation and filtration. The SafBon DAF shows higher removal rate in low density contaminants (density < H2O, such as plankton, algae and oil) removal than the conventional processes. The CFM application in filtration process, results in following benefits:
Longer lifetime: 3-5 times longer;
Higher flux: 2-10 times higher;
Less chemical consumption: 50% less;
Less energy consumption: 50% less;
High recovery rate: up to 98%;
Less back-wash: once per day, only 120 s needed;
Higher mechanical strength: easy for cleaning.
