Temporary Strainers for Desalination Plant Commissioning

Temporary strainers are temporary filtration devices installed during the commissioning of systems like desalination plants. Their primary purpose is to remove dirt, scale, welding slag, and other unwanted particles that may enter the system during installation or early operation. Unlike permanent filters, these temporary strainers are removed once the system stabilizes and debris levels are reduced.

Our metal temporary strainers come in various types, including:

▪ Cone temporary strainers: Ideal for short-term filtration and suitable for systems with moderate flow rates.

▪ Basket temporary strainers: Designed for higher debris loads and larger pipelines.

▪ Plate temporary strainers: Flat designs that are cost-effective and versatile for lower flow conditions.

The Role of Temporary Strainers in Desalination Plant Commissioning

The commissioning phase of a desalination plant involves running the system under test conditions to ensure it meets performance standards. During this stage, temporary strainers are used in the following ways:

▪ Protecting Pumps and Valves

Large desalination plants involve complex networks of pumps, valves, and sensitive equipment. Temporary strainers ensure that no debris or construction material damages these components during initial operation.

▪ Safeguarding Re verse Osmosis (RO) Membranes

RO membranes are the heart of any desalination plant, responsible for removing salt and impurities from seawater. Debris in pipelines can clog or damage these membranes, leading to costly repairs or replacements. Temporary strainers act as the first line of defense against contaminants.

▪ Preventing Pipeline Blockages

During commissioning, pipelines may carry residual construction materials such as welding slag or rust. Temporary strainers ensure these contaminants do not obstruct the flow or compromise system performance.

▪ Ensuring System Cleanliness

Temporary strainers help achieve a clean system before permanent filtration systems take over, providing a smooth transition from the commissioning phase to regular operation.

Application Case of Temporary Strainers

This year we provided Saudi Arabia with a batch of temporary filters for the commissioning of seawater desalination plants. The filters were custom-designed, and the response was very good.
