Raw Water Pretreatment

Raw Water Pretreatment

No matter where your make-up water comes from, it may contain contaminants that can foul or damage downstream equipment and affect the final process water quality.

Industrial pretreatment on-site services

Surface water, well water or reclaimed water can contain suspended solids, colloidal matter, organics, hardness, silica, iron, manganese and other contaminants. That’s why it’s so important to choose the proper water pretreatment system for your process.

Siemens Water Technologies can help you design the most efficient, reliable and cost-effective pretreatment system, regardless of how challenging your water treatment needs may be.

Raw Water Pretreatment Case Study

Softeners Remove Hardness to Protect Downstream Reverse Osmosis (RO) Systems

A Midwestern company was experiencing frequent cleanings of their reverse osmosis (RO) system due to severe scaling on the membranes. As is the case with most Midwestern well waters, high levels of calcium and magnesium adversely affect many operations that use this water. The problems experienced with the RO system:

Declining water quality
Increased pressure drops, especially in the last stage of the RO system
Higher pressures required
Frequent cleanings to restore performance
Frequent and extensive downtime

The plant manager needed technical assistance and a quick, dependable raw water pretreatment solution.
