Seawater Reverse Osmosis Units
From Water Treatment
RO Capacity:
RO Capacity:
Tech Universal's package RO Units range between 5-2,000 m3 /hr. Above 2,000 m3 /hr units are custom design built to client specification.
Process:
The raw water is drawn from the raw water tank using filter feed pumps to feed the water into the dual media sand filter. Before the filters, the raw water is injected with Sodium Hypochlorite to kill any bacteria present in the water before entering the Reverse Osmosis Unit.
Also, the water is injected with the following chemicals:
- Sodium Metabisulphate
- Sulphuric acid
- Anti-scalant
Sodium Metabisulphite gets rid of all traces of chlorine in the water to protect the membrane fibres.
The water is then pressurised by the high-pressure pump up to 26-28 bar, depending on design conditions, going into the membranes, where water is then separated into permeat and the reject streams.
The product water from all membranes is collected in one manifold and then pumped to the product water tank. Before entering the product water tank, the water is pH corrected and sterilised using the Chlorination system.
Tech Universal, uses an automatic flushing system, which is in an integral part of the R.O. Unit design helping to prolong the life of the membranes
