Sokalan: A Powerful Ally in the Fight Against Desalination Scaling
The Problem: Desalination, the process of removing salt from seawater to produce freshwater, is a crucial solution to water scarcity. However, a major challenge lies in the formation of mineral deposits, known as scale, on desalination plant membranes. These deposits significantly reduce plant efficiency and require costly cleaning and downtime.
The Solution: Enter Sokalan, a range of high-performance antiscalants developed by BASF. These specialized chemicals effectively prevent scale formation by modifying the crystallization process of minerals like calcium carbonate and calcium sulfate.
Sokalan: A Comprehensive Antiscalant Solution:
- Diverse Product Portfolio: BASF offers a wide range of Sokalan products, each tailored to specific desalination conditions, including:
- Sokalan® DS 1000: A high-performance antiscalant with excellent calcium carbonate and calcium sulfate inhibition capabilities.
- Sokalan® DS 1200: Formulated to effectively inhibit barium sulfate scaling in high-pressure membrane applications.
- Sokalan® DS 1400: A powerful antiscalant for challenging applications, effectively inhibiting multiple types of scale formation.
- Advanced Technology: Sokalan utilizes cutting-edge technology to ensure efficient and environmentally friendly scale control.
- Optimized Performance: Sokalan products are specifically designed to work effectively in high-salinity seawater environments, providing long-term protection against scaling.
- Sustainability Focus: BASF prioritizes the development of sustainable solutions, ensuring minimal environmental impact and responsible water resource management.
Benefits of using Sokalan:
- Reduced Operating Costs: Preventing scale formation minimizes cleaning and downtime, leading to significant cost savings.
