An analysis of desalination pre-treatment, wastewater circular economy, and supply chain strategies.
Israel is globally renowned for its pioneering approach to water resource management. With over 85% of municipal wastewater reclaimed for agricultural use and a heavy reliance on seawater desalination (which provides roughly 80% of the country's domestic tap water), water quality is not just an environmental issue—it is a matter of national security. Advanced chemical pre-treatments like Polyaluminum Chloride (PAC) play an indispensable role in maintaining this delicate ecosystem.
In desalination facilities, such as those in Ashkelon, Sorek, and Hadera, PAC is used as a primary coagulant to remove suspended solids, microalgae, and organic colloids before seawater hits the delicate Reverse Osmosis (RO) membranes. Failure to optimize this step leads to rapid biofouling, decreased membrane lifetime, and elevated operating pressures, which drastically increase operational costs.
Unlike traditional monomeric coagulants like Aluminum Sulfate (Alum), Polyaluminum Chloride features a pre-hydrolyzed polymeric structure dominated by the highly charged Al13 Keggin structure ([Al13O4(OH)24(H2O)12]7+). This complex molecule delivers several operational advantages:
The Israeli Ministry of Environmental Protection enforces stringent standards for both potable water treatment and wastewater effluent discharge. Industrial plants in the Haifa Bay industrial zone, chemical manufacturers near the Dead Sea, and municipalities nationwide must keep phosphorus, heavy metal residuals, and chemical oxygen demand (COD) levels to absolute minimums.
Wuxi BS Water Treatment Chemicals Co., Ltd. customizes its PAC formulations to comply with drinking water criteria similar to NSF/ANSI Standard 60, ensuring low heavy-metal (Pb, As, Cd) parameters suitable for municipal distribution lines in Jerusalem and Tel Aviv.
Founded in 1998, Wuxi BS Water Treatment Chemicals Co., Ltd. is a technology pioneer in the synthesis of advanced macromolecular polymers and water purification chemistry. Our facility incorporates advanced automated production lines to serve municipal and industrial facilities globally.

Addressing technical and commercial queries regarding the application of PAC coagulants.
PAC features pre-hydrolyzed polymeric structures that charge-neutralize colloids much faster than monomeric Alum. It operates effectively over a broader pH range (5.0–9.0) and generates larger, more shear-resistant flocs, which are easier to filter out before seawater reaches Reverse Osmosis membranes.
Unlike Alum, whose hydrolysis is highly temperature-dependent, PAC remains highly effective in colder temperatures. The pre-formed polymeric species do not require additional energy to hydrolyze, making PAC suitable for seasonal temperature fluctuations.
For solid PAC products, we provide 25kg double-layer PE/PP bags and 1000kg jumbo bulk bags. For liquid formulations, we ship in custom IBC totes or flexitanks to protect cargo integrity throughout transit.
Optimal dosage is determined via jar testing to account for factors like raw water turbidity, pH, and organic load. Our technical team is available to assist you in assessing these parameters for your specific operation.
