Brine & Post-Treatment Skid Cost in Egypt (2026)

A brine post-treatment and remineralisation chemistry skid for an Egyptian seawater RO plant lands in an indicative band of roughly $150,000 to $1.5 million, depending on plant size, build standard, and whether it includes limestone contactors, lime and CO2 dosing, and brine-outfall conditioning. The running chemistry adds roughly $0.04 to $0.10 per cubic metre of permeate. Here is how that budget breaks down and who issues the RFQ.

Every one of the 21 seawater reverse osmosis plants in Egypt’s Phase 1 desalination programme needs this skid. RO permeate leaves the membrane racks corrosive, acidic, and stripped of the calcium and magnesium that make water drinkable and pipe-friendly, so before it enters the network it has to be remineralised, pH-corrected, and stabilised against the cement-lined mains. On the reject side, the concentrate has to be conditioned before it reaches the outfall. That conditioning package, pre-treatment dosing plus post-treatment remineralisation plus brine handling, is a separately-quoted sub-package on every plant.

This post maps the indicative cost of that package for a foreign skid builder scoping Egypt. It sits under our Egypt water and wastewater procurement guide and the Egypt industrial and procurement guide.

What the Skid Actually Is

“Brine post-treatment chemistry skid” covers three chemistry packages that are sometimes quoted together and sometimes split.

Post-treatment remineralisation is the headline item. SWRO permeate is too pure to send to consumers, so calcium and bicarbonate alkalinity get added back. Per the remineralisation and stabilisation review in IntechOpen, one route runs acidified permeate through a packed bed of millimetre-size limestone (calcite) grains, with the dissolution driven by carbon dioxide: CaCO3 plus CO2 plus water yields calcium bicarbonate. The other doses a saturated lime solution, made on site from hydrated lime or quicklime, into the final water together with CO2 to form bicarbonate alkalinity. A typical potable target is around 80 mg/L of hardness and alkalinity as calcium carbonate, with the finished water held slightly precipitative (pH above the saturation point) so it lays a thin protective scale on cement-lined pipe rather than corroding it.

Pre-treatment dosing sits upstream of the membranes: a coagulant such as ferric chloride to drop suspended solids before filtration, an antiscalant to keep the membranes from fouling, and sodium bisulphite to neutralise residual chlorine. The pre-treatment review in Environmental Engineering Research sets out these coagulation, scale-inhibition, and pH-adjustment steps. Antiscalant dosing typically runs 0.5 to 4 mg/L.

Brine and outfall conditioning handles the reject, roughly twice the salinity of seawater, with degassing, pH trim, and outfall dosing.

These are pre-assembled, instrumented chemistry skids, not bulk plant, which makes them a clean sub-package a specialist can quote into the main EPC contractor without bidding the whole plant.

Indicative Budget Ranges for Egyptian SWRO Skids

These are indicative budget bands, not quotes. Real pricing depends on capacity, redundancy, materials, instrumentation, and the contractor’s specification. Build the real number from the plant data sheet.

For context, Egypt’s first large desalination plant, the Al Yousr SWRO plant at Hurghada, is an 80,000 m3/day two-pass facility serving more than 500,000 residents, built by Metito, with a post-treatment train of limestone contactors, a CO2 injection system, a degasser, a blending tank, and a pump station.

On a plant in the 40,000 to 80,000 m3/day band, expect three rough cost lines. A pre-treatment dosing skid set (coagulant, antiscalant, and bisulphite, with metering pumps, tanks, mixers, and local control) tends to run roughly $120,000 to $400,000. The post-treatment remineralisation package (limestone contactor vessels or a lime saturator, CO2 storage and injection, a degasser, and the blending and pump arrangement) is the big ticket at roughly $400,000 to $1.5 million, with the contactor route generally heavier on civil and vessel cost than a lime route. Brine and outfall conditioning dosing is a smaller add-on, often $80,000 to $250,000.

The 40,000 m3/day Dabaa plant and the 190,000 m3/day El Hamam plant, named for the first tenders, bracket the skid sizes the programme will procure. A larger train pushes the post-treatment package toward the top of these bands and sometimes beyond, because contactor volume and CO2 capacity scale with flow.

Running cost is where a buyer’s total-cost lens lands. The remineralisation review in IntechOpen puts the lime-and-CO2 or calcite chemistry at a few cents per cubic metre of permeate, with full-scale studies landing remineralisation at roughly $0.04 to $0.10 per cubic metre. For an 80,000 m3/day plant near capacity, even a few cents per cubic metre is a meaningful annual spend, which is why dosing accuracy and the limestone-versus-lime trade-off are real procurement decisions. A bid that shows reagent efficiency competes on more than sticker price.

The Demand: Every Plant in a $3 Billion Programme

The reason this niche is worth chasing in Egypt is volume. Phase 1 of the national desalination programme is 21 plants worth roughly $3 billion, targeting 3.35 million m3/day of new capacity, as reported by Smart Water Magazine and Al Majalla’s report on the Sovereign Fund’s plan. The first six plants, around 900,000 m3/day for roughly $900 million, are targeted for operation in FY2025-26, with Dabaa (40,000 m3/day) and El Hamam (190,000 m3/day) named for the first tenders. The 30-year roadmap scales to 8.85 million m3/day by 2050.

Every one of those plants needs a post-treatment remineralisation package and a pre-treatment dosing set. The skid is on the bill of quantities of every SWRO plant in a multi-decade national programme, so a supplier who qualifies it once can quote it into plant after plant.

Who Issues the RFQ in Egypt

The chemistry skid is almost never bought by a ministry. The buying centre sits one level down, inside the project.

The programme runs as public-private partnerships led by the Sovereign Fund of Egypt (TSFE) with the Ministry of Finance’s PPP Central Unit, which prequalified 17 consortia across four capacity categories. Each plant is awarded as a long-term BOOT or BOO concession, so the equipment buyer is the private project company, financed by development-bank and commercial debt, not a cash-strapped municipality. The advisory layer behind that structure, with the IFC and EBRD advising TSFE, is set out in the IFC’s release on the partnership to increase Egypt’s clean water supply.

In practice you sell to the EPC contractor inside the winning consortium. The dominant Egyptian water EPC is Hassan Allam Construction, which consolidated its position in 2026 by acquiring MetiPro, the EPC arm of water-technology group Metito. Metito, Orascom Construction, and The Arab Contractors are the other heavyweight integrators, with Acciona Agua, Suez International, and Veolia on the international side inside the prequalified consortia. The full consortium map is in our Egypt water sector guide. By the time a plant reaches public award, the skid short-list is usually already forming among the bidders, so qualification with the EPC contractors before financial close is the real route in.

How These Skids Get Paid

For a skid sold into a concession, you are paid by a well-capitalised project company under a structure built to be bankable to international lenders, a far stronger counterparty than a governorate water company. For direct supply into a contractor, the dominant instrument remains the irrevocable letter of credit for packages over roughly $250,000, issued by an Egyptian bank such as NBE, Banque Misr, CIB, or QNB Al Ahli, and confirmed by an international correspondent bank for larger tickets. Since the 2024 FX unification, hard-currency access has materially improved and industrial LCs clear on standard timelines. Full FX and LC detail is in our Egypt procurement pillar.

Two skid-specific realities to model in. Retention of 5 to 10 percent gets held for 12 to 24 months against commissioning, which is meaningful working capital on a skid package. And export credit agency cover has decided several Egyptian water awards, so suppliers with active ECAs, Germany via Euler Hermes, Italy via SACE, France via Bpifrance, plus the export banks of Japan, Korea, and China, should bring financing into the bid early. Suppliers from established water-technology bases compete on engineering and dosing-control quality rather than price; see how Canadian water treatment equipment manufacturers position on treatment technology when they sell into export markets.

Dying Conventional Channels for This Equipment Line

The traditional ways a foreign skid supplier reached Egyptian desalination buyers are losing ground.

Water trade fairs deliver less than they used to. WETEX-style regional water exhibitions and the water tracks at events like the Big 5 in Egypt still draw exhibitors, but the cost per qualified lead has climbed past $300 to $900 and beyond once you add booth, freight, and staff travel against a still-volatile pound. The engineers who specify dosing and remineralisation packages tend to stay at the office while junior staff walk the floor, so a stand produces a few business cards and then months of silence.

Expat field sales reps in Cairo are economically broken for one equipment line. A European or American process-equipment sales engineer based in Cairo runs roughly $120,000 to $200,000 fully loaded per year with housing, schooling, and post-2024 cost-of-living adjustments. Against the deal flow a single skid line sustains, the cost per qualified lead lands at $500 to $1,200 and beyond.

Distributor lock-in is fragmenting. Routing all Egyptian volume through one local agent no longer reaches the buying centres, because the EPC contractors and project companies increasingly specify and procure key chemistry packages directly from the OEM. The print water press reaches a thin slice of the engineers who write SWRO post-treatment specs; those specifiers research suppliers through LinkedIn, Google, project references, and direct outreach. None of these channels are dead. They simply scale linearly or worse, and cost more per lead as you push for volume.

Where Modern Outbound Fits

A modern AI-driven outbound motion, tuned to Egyptian desalination procurement, runs at $150 to $300 per qualified lead at the start and gets cheaper as it learns. It targets named procurement and engineering leads inside the EPC contractors, Hassan Allam, Metito, Orascom, Arab Contractors, and Acciona, in English where senior Egyptian water procurement happens and Arabic where the buyer prefers, every working day of the year. Against a fair at $300 to $900 per lead and a Cairo rep at $500 to $1,200 per lead, both scaling linearly or worse, the compounding economics matter most on a programme broad enough that any single channel under-covers it. Twenty-one plants, each needing a chemistry skid, is exactly that surface area.

FAQ

How much does a desalination post-treatment remineralisation skid cost in Egypt?

As an indicative band, a post-treatment remineralisation package for a 40,000 to 80,000 m3/day SWRO plant runs roughly $400,000 to $1.5 million, depending on whether it uses limestone contactors or lime dosing, plus CO2 injection and degassing. Pre-treatment dosing skids add roughly $120,000 to $400,000. Build the real number from the plant data sheet.

What chemicals are used in SWRO post-treatment in Egypt?

Remineralisation adds calcium and bicarbonate alkalinity back to the permeate, either by dissolving limestone (calcite) with CO2 or by dosing lime (calcium hydroxide) with CO2. A typical target is around 80 mg/L hardness and alkalinity as calcium carbonate, with the water held slightly precipitative to protect cement-lined pipe.

How big is Egypt’s desalination programme for skid suppliers?

Phase 1 is 21 plants worth roughly $3 billion, targeting 3.35 million m3/day, run as public-private partnerships by the Sovereign Fund of Egypt. The first six plants, around 900,000 m3/day, target operation in FY2025-26. The roadmap scales to 8.85 million m3/day by 2050. Every plant needs post-treatment and dosing skids.

Who buys brine and post-treatment skids in Egypt?

The EPC contractor inside the winning desalination consortium, not a ministry. The lead integrators are Hassan Allam Construction, which acquired Metito’s EPC arm MetiPro in 2026, plus Metito, Orascom Construction, Arab Contractors, Acciona Agua, and Suez International. Qualification with these contractors before financial close is the route in.

How are skid packages paid in a post-2024 FX market?

Concession plants pay through well-financed private project companies. Direct supply uses irrevocable letters of credit confirmed by an international bank, which clear on standard timelines since the 2024 FX reform. Expect 5 to 10 percent retention held for 12 to 24 months, and bring export credit agency cover into the bid early.
