The Arabian Gulf and the Red Sea are major sources of seafood and vital reservoirs of two of the most precious resources: water and oil.

The rich marine ecosystems within these bodies of water are characterized by a diverse array of unique and indigenous plants and animals that play crucial roles in maintaining ecological balance.

However, these sensitive habitats may experience significant physical and chemical stresses if the natural equilibrium is disturbed. 

黑料社区 is taking a leadership role on the global stage with its innovative and patented technologies developed by the Saudi Water Authority鈥檚 Water Technology Innovation and Research Development Institute.

These initiatives are focused not only on efficient desalination, but also on the responsible management of brine as a resource rather than merely as a waste product.

WTIIRA-SWA has created a groundbreaking dual brine concentration design that combines a nanofiltration system upstream of a reverse osmosis system and a membrane brine concentration system downstream.

This technology enables the extraction of two valuable brine streams: one that consists of concentrated and purified monovalent ions, which can be used to produce high-purity sodium chloride and bromine, and another that is rich in divalent ions usable for manufacturing various calcium and magnesium salts.

Such innovation not only contributes to the sustainability of desalination processes but also opens new avenues for economic viability, connecting the desalination industry to a range of applications in sectors such as chlor-alkali production, pharmaceuticals and cosmetics.

These initiatives are focused not only on efficient desalination, but also on the responsible management of brine as a resource rather than merely as a waste product.

Another noteworthy achievement in this field is the extraction of vaterite calcium carbonate, distinguished by its unique chemical properties, including high porosity, increased surface area, greater solubility and biodegradability.

These attributes make vaterite calcium carbonate especially suitable for controlled release in pharmaceutical formulations, serving as an effective carrier for drug delivery. By harnessing such advanced materials, WTIIRA-SWA underscores its commitment to innovation in resource recovery.

Moreover, WTIIRA-SWA has implemented several pioneering strategies to minimize the environmental impact of desalination brine and preserve the precious ecosystems surrounding the Kingdom.

Efficient technology implementation: Modern desalination plants in 黑料社区 utilize advanced technologies that emphasize energy efficiency and environmental sustainability. 

Brine disposal management: In 黑料社区, the strategies for brine disposal are carefully considered. Detailed studies of dilution factors, dispersion patterns, and the assimilative capacity of the receiving marine environment are conducted to ensure that discharged brine is safely integrated without detrimental effects on marine life.

Monitoring and regulation: Rigorous environmental monitoring programs are established to assess the impact of desalination plant effluents on the marine ecosystem. 

Coastal ecosystem preservation: Strategic placement of desalination plants is intended to reduce impacts on sensitive coastal ecosystems. 

Research and development: Ongoing research and development initiatives aim to improve desalination technologies and processes further. 

Through these comprehensive approaches, WTIIRA-SWA is not only addressing the challenges of desalination but also setting a global standard for sustainability in the management of water resources.

  • Palestinians fear land fragmentation will rob them of any chance to build a state of their own in the area

MAALE ADUMIM: Israeli far-right Finance Minister Bezalel Smotrich announced work would start on a long-delayed settlement that would divide the West Bank and cut it off from East Jerusalem, a move his office said would 鈥渂ury鈥 the idea of a Palestinian state.

The Palestinian government, allies, and campaign groups condemned the scheme, calling it illegal and saying the fragmentation of territory would rip up peace plans for the region.
Standing at the site of the planned settlement in Maale Adumim on Thursday, Smotrich, a settler himself, said Prime Minister Benjamin Netanyahu and US President Donald Trump had agreed to the revival of the E1 development. However, there was no immediate confirmation from either.
鈥淲hoever in the world is trying to recognize a Palestinian state today will receive our answer on the ground, not with documents nor with decisions or statements, but with facts. Facts of houses, facts of neighborhoods,鈥 Smotrich said.
Israel froze construction plans at Maale Adumim in 2012, and again after a revival in 2020, because of objections from the US, European allies, and other powers who considered the project a threat to any future peace deal with the Palestinians.
Restarting the project could further isolate Israel, which has watched some of its Western allies condemn its military offensive in Gaza and announce they may recognize a 
Palestinian state.
Palestinians fear the settlement building in the West Bank 鈥 which has sharply intensified since the 2023 Hamas attack on Israel that led to the Gaza war 鈥 will rob them of any chance to build a state of their own in the area.
In a statement headlined 鈥淏urying the idea of a Palestinian state,鈥 Smotrich鈥檚 spokesperson said the minister had approved the plan to build 3,401 houses for Israeli settlers between an existing settlement in the West Bank and Jerusalem.
In Maale Adumim, Smotrich said the plan would go into effect on Wednesday.
Breaking the Silence, an Israeli rights group established by former Israeli soldiers, said what it called a land grab 鈥渨ill not only further fragment the Palestinian territory, but will further entrench apartheid.鈥
Nabil Abu Rudeineh, the Palestinian president鈥檚 spokesperson, called on the US to pressure Israel to stop settlement building.
鈥淭he EU rejects any territorial change that is not part of a political agreement between the involved parties. So annexation of territory is illegal under international law,鈥 European Commission spokesperson Anitta Hipper said.
Norwegian Foreign Minister Espen Barth Eide said the move by Smotrich, an ultra-nationalist in the ruling right-wing coalition who has long advocated for Israeli sovereignty over the West Bank, showed that Israel 鈥渟eeks to appropriate land owned by Palestinians in order to prevent a two-state solution.鈥
Peace Now, which tracks settlement activity in the West Bank, said there were still steps needed before construction. 
However, if all goes through, infrastructure work could begin within a few months, and house building could start about a year later.
鈥淭he E1 plan is deadly for the future of Israel and for any chance of achieving a peaceful two-state solution. We are standing at the edge of an abyss, and the government is driving us forward at full speed,鈥 Peace Now said in a statement.
Consecutive Israeli governments have initiated, approved, planned, and funded settlements, according to Israeli rights group Yesh Din.
Some settlers moved to the West Bank for religious or ideological reasons, while lower housing costs and government incentives drew others. 
They include American and European dual citizens.
Palestinians were already demoralized by the Israeli military campaign, which has killed more than 61,000 people in Gaza, according to local health authorities, and fear Israel will ultimately push them out of that territory.
About 700,000 Israeli settlers live among 2.7 million Palestinians in the West Bank and East Jerusalem. 
Israel annexed East Jerusalem in a move not recognized by most countries, but has not formally extended sovereignty over the West Bank. 
The UN and most world powers say settlement expansion has eroded the viability of a two-state solution by fragmenting Palestinian territory. 
The two-state plan envisages a Palestinian state in East Jerusalem, the West Bank, and Gaza, existing side by side with Israel.
Most of the global community considers all settlements illegal under international law.
Israel rejects this interpretation, saying the West Bank is 鈥渄isputed鈥 rather than 鈥渙ccupied鈥 territory.
Britain, Canada, Australia, and New Zealand imposed sanctions in June on Smotrich and another far-right minister who advocates for settlement expansion, accusing both of them of repeatedly inciting violence against Palestinians in the West Bank.
