Water Net Zero (Rechsand)

Water Net Zero (operates as part of Rechsand) is a company specializing in nanocoated sand solutions. With over 30 years of experience, the company develops sand-based technologies to address various environmental and industrial challenges. Holding more than 670 international patents, the company focuses on creating innovative solutions for petroleum extraction, flood prevention, desert agriculture, and energy-efficient construction.

Their main products include:

• FSS Type II - A nanocoated sand product designed for downhole consolidation and sand control in oil wells, operating at temperatures between 25-150°C with consolidation strength of ≥10MPa

• FSS Type IV - A gas-permeable and hydrophobic sand solution that maintains water conductivity while controlling water flow

• FSS Type V - A self-suspending sand product that achieves 93.80% buoyancy in fracturing water, reducing the need for chemical additives

• Filter Pavers - Water-permeable pavement solutions that manage urban flooding, filter water contaminants, and resist snow accumulation

The company has established significant partnerships with various oil fields including Karamay, Tuha, Jilin, and Qinghai, achieving a 100% construction success rate in fracturing applications. Their technology has been recognized by the United Nations and the Chinese government, with their approach being termed the "Rechsand Model." The company's FSS Type II-NJ product notably solved sand control challenges in Daqing Oilfield's ternary composite flooding system, marking a world first in this application.
