Optimize Desalination Processes

Entsalzung

Desalination is vital for drinking water due to population growth however; Seawater's high salinity and mineral content are extremely corrosive, leading to frequent maintenance and replacements. Bray offers robust solutions to these challenges with our range of corrosion-resistant valves, including lined valves and superalloys that are ideal for the harsh conditions of seawater, ensuring reliable operations, minimizing downtime, and ensuring sustainable operation.

Pre-Treatment

Pretreatment is a vital step in seawater desalination plants, designed to remove suspended solids, microorganisms, and other contaminants before the seawater enters the reverse osmosis process. Bray manufactures a full line of resilient seated butterfly valves featuring advanced materials and coatings, such as peroxide-cured EPDM, Nylon coated / duplex discs, as well as resilient-seated ball valves, that provide exceptional resistance to corrosion, chemical attack, and biofouling. Our valves are designed for reliability and long-term performance, ensuring consistent operation even under continuous exposure to aggressive seawater and pretreatment chemicals.

Umkehrosmose

Reverse Osmosis (RO) is a critical step in Seawater Desalination. This method involves pushing seawater through a semi-permeable membrane under high pressure, which allows only water molecules to pass through while blocking salts and impurities. This results in the production of fresh, potable water but leaves the water demineralized and slightly acidic. Bray manufactures a a range of valves engineered for R.O. systems, able to withstand the harsh conditions of seawater, while ensuring reliable operation and low maintenance that improves your operations bottom line.

Post Treatment

Post-treatment in seawater desalination is vital because water produced by reverse osmosisis is mineral-deficient and slightly acidic. Two key processes are required: Brine Management and Remineralization. Bray Valves, made from corrosion-resistant alloys and resilient seats, ensure reliable performance in brine management when exposed to aggressive salts and chemicals. In remineralization, essential minerals like calcium and magnesium are added to stabilize pH and restore its suitability for drinking and other uses. Bray's ball and butterfly valves provide precise control for mineral injection. CO₂ dosing, and pH adjustment, ensuring desalination plants deliver safe, high-quality water with efficient and sustainable operation.
