New services
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.

What we actually do
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.
The machine, not the brochure
Every plant is sized on the water you actually have.
Feed TDS, hardness, silica, temperature and recovery decide the array. We write that into the BOQ: membranes, vessels, HP pump duty, dosing, CIP, panel protection, container fit-out.
- SW 8040 / BW 8040 elements selected for the feed salinity and recovery
- 5-element 600 psi FRP vessels · SS304 / duplex piping
- Containerized 20 ft economy or 40 ft HC industrial
- PLC + HMI or contactor panels with dry-run stop
CIP, antiscalant / acid dosing, cluster pre-filtration
Reuse · hospitality · wash
70% of the sewer stream, back as rinse water.
Hotels, central laundries and car-wash stations throw away water that can be recovered. Mai Fina specifies an MBR train on grey / laundry wastewater: screening, biological treatment, membrane separation, optional RO polish. Product is used on the final rinse so wash quality rises and freshwater demand falls.
Water is life's matter. There is no life without water.
Design recovery: approximately 70% of sewer / grey flow returned as rinse-grade water
MBR cassette + optional RO polish where TDS or colour must drop further
Improves washing quality on linen and vehicles by feeding a dedicated clean rinse
Cuts tanker discharge and DEWA / ADDC consumption on hotel and laundry accounts
Softening · DI · Demin
400 GPD to 100,000 GPD — one range, two duties.
Water softeners for hotels, laundries, villas and boilers. De-ionisation / demineralisation (DI · DE-M) from laboratory 400 GPD skids to industrial mixed-bed and EDI trains up to 100,000 GPD. Same engineering desk as the RO plants.
