What we actually do
Water treatment services across the UAE
From borewell chemistry to permeate at the tap.
Not a bottled-water shop. Mai Fina is a process house: feed analysis, recovery, membrane selection, high-pressure pumping, CIP, controls, delivery, installation and commissioning — written into quotations, delivery notes and service reports.
Industrial & camp RO
Containerized 20,000–100,000 GPD trains for oilfield camps, utilities and factories. Feed analysis first, then the array: BW or SW 8040 elements, 600 psi vessels, specified HP and feed pumps, CIP, dosing, pre-filters and a panel with dry-run and empty-tank protection.
Seawater & high-TDS SWRO
When borewell TDS leaves the brackish range (12,300 mg/L and above), the plant is built on full seawater SW 8040 elements in 600 psi FRP vessels: higher rejection, safer flux and CIP chemistry sized for seawater fouling.
EDI electrodeionization
Chemical-free polishing after RO: an electric field and ion-exchange membranes remove the remaining ions for near-zero TDS, lab-grade water (typically 10–15+ MΩ·cm, up to 18.2 MΩ·cm with a polish). From 400 GPD lab skids to industrial trains.
Dialysis water systems
Purified water for hospital dialysis: softener, carbon, double-pass RO, optional EDI or UF and a disinfectable loop, designed to ISO 23500 limits (<100 CFU/mL, <0.25 EU/mL endotoxin), with monitoring and AMC.
Industrial desalination & food-processing RO
Brackish and seawater desalination for factories and process plants, plus food-grade RO for beverage, dairy, bakery and food processing: hygienic materials, consistent product TDS, sized on the real feed analysis.
Boiler water treatment
Softening, RO or EDI makeup, chemical dosing, blowdown and conductivity control to cut scale, corrosion and fuel loss on low- and high-pressure boilers.
ATP bioluminescence testing
Rapid ATP testing for RO plants, dialysis loops, tanks and food lines: biological contamination and biofilm trends in minutes, between lab results.
DI deionization water systems
Cation/anion and mixed-bed resin units, regenerable or service exchange (SDI) cylinders, with conductivity monitoring for labs, batteries, electronics, autoclaves, boiler make-up and cosmetics.
Handheld TDS meters
Pen-style TDS / conductivity meters for quick checks on RO permeate, drinking water, filters and tanks, with guidance on test points and target readings.
Ultrameter water quality meter
Myron L Ultrameter II or equivalent: conductivity, TDS, resistivity, pH, ORP, free chlorine and temperature in one handheld for RO, DI and boiler water.
RO chemicals
Antiscalants (ATMP, HEDP, PBTC, HPMA, PESA, PASP), CIP cleaners, DBNPA biocide and SMBS for brackish water and seawater RO.
Activated carbon
GAC and PAC for chlorine and chloramine removal, taste and odor, organics and RO membrane protection.
Ozone generators
Corona discharge ozone with oxygen or air feed, injector, contact tank, ORP control and off-gas destruct for bottled water, pools, cooling towers and laundry.
RO membranes
BWRO, SWRO, low-energy and fouling-resistant elements in 4040 and 8040, with replacement, cleaning and membrane autopsy.
Filter cartridges
PPF, PPY, CTO carbon block, GAC and pleated cartridges in 10/20/40 inch, slim and Big Blue, 1 to 25 micron.
8-stage home RO, 100 to 1000 GPD
Under-sink 8-stage RO, models from 100 to 1000 GPD: sediment, carbon, RO, remineralisation and UV, with faucet, tank or tankless, installation and filter service.
RO water dispensers, 100 to 1000 GPD
Embedded or countertop RO dispensers, models from 100 to 1000 GPD, with hot, cold, ambient and sparkling water for homes, offices, hotels and restaurants.
Dosing pumps
Solenoid and motor diaphragm dosing pumps with pulse, 4-20mA or flow-proportional control, tanks, injection valves and calibration columns.
High-pressure pumps
Multistage centrifugal and plunger RO feed and booster pumps, duplex / super-duplex for SWRO, with VFD and energy recovery.
Water softeners
Simplex and duplex ion-exchange softeners with metered or time regeneration, brine tank, bypass and hardness testing.
AMC for RO plants
Annual maintenance contracts for RO, softener, DI / EDI and MBR systems: preventive visits, cartridge changes, CIP, chemicals, testing and emergency support.
Sewage treatment plants (STP)
MBR, MBBR, SBR and extended aeration STPs for camps, hotels and communities, packaged, containerized or civil, with treated water reuse.
Effluent treatment plants (ETP)
Industrial ETPs: pH neutralization, oil separation, DAF, coagulation, biological treatment, filter press and RO / ZLD options.
Agriculture & farms
Controlled product TDS for hydroponics, date farms and livestock so salinity does not burn the root zone or scale drippers. New skids or restoration of existing farm plants, designed on the actual well analysis.
Bottled water & filling
Factory RO with sand/carbon, antiscalant, UV and mineral dosing where specified, plus filling-line packages scoped line by line so you see exactly what is in our supply.
Softeners & AMC
Duplex softeners with brine tank and AMC: scheduled visits, regeneration tests, salt top-up and cartridge changes where contracted. Emergency visit within 24 hours; 24/7 phone support.
Hotels & commercial laundry
Softener on the city feed for bright, scale-free linen, plus MBR recycling on wash and rinse drains returning 70–80% as final-rinse water. Better wash quality and lower DEWA/ADDC and tanker bills.
Grey water & MBR recycle
Screening, equalisation, biology, submerged MBR cassette and disinfection with optional RO polish, recovering 70–80% of grey, sewer and laundry water as rinse, flushing or irrigation water.
Car-wash recycle plant room
A tiled equipment room beside the wash hall: collection sump, oil-water separator, grit removal, UF or MBR, product tank and panel. Recycled water feeds the rinse arches; fresh makeup only for a spot-free last pass.
