Water Treatment Programme
Scale, corrosion and biological control for cooling towers, chillers and boilers — chemicals, dosing equipment, on-site water testing and one accountable engineer.
Bangladeshi make-up water is hard and warm, and open towers breed algae in weeks. Left alone, a condenser loses 10–15% capacity to scale in a single summer and a tower fill chokes in two. MHM's water-treatment programme puts the chemistry and the dosing hardware in one pair of hands, with Finor chemicals blended for local water.
An MHM water engineer tests the circuit, sets bleed and dose, and reports hardness, conductivity, inhibitor residual, pH and microbiological counts against the targets — the same log your ISO auditor asks for.
Everything water treatment programme covers
Programme design
Raw-water analysis, cycles-of-concentration target, chemical selection and dose rates.
Dosing & bleed equipment
Metering pumps, conductivity-controlled bleed, tanks and injection points installed.
Chemical supply
Finor scale/corrosion inhibitors, oxidising and non-oxidising biocides, boiler treatment.
Water testing & report
Hardness, alkalinity, conductivity, pH, residuals, dip slides — tested on site and reported against the targets.
Cleaning & passivation
Off-line descaling of condensers and towers, new-system passivation.
Legionella control
Disinfection plan and records for towers serving hospitals, hotels and offices.
From first call to handover
- 1
Water & system audit
Samples from make-up and circuit, coupon rack installed, existing scale assessed.
- 2
Programme start
Equipment installed, initial clean where needed, dose set and operators trained.
- 3
Follow-up testing
Testing, dose adjustment and chemical supply whenever the plant needs it.
Water Treatment Programme for every part of the utility block
The service lines our engineers design, install and look after under this offering.
Chillers
MHM-manufactured and imported chillers — air cooled and water cooled, 5–850 TR.
Cooling Towers
MHM-manufactured FRP cooling towers and imported towers — supplied, erected and rebuilt by one team.
Water Treatment Plants & Chemicals
RO, DM, softener and effluent treatment plants, plus treatment chemicals for cooling towers, chillers and boilers.
Common questions about water treatment programme
An inhibitor programme stops new scale; existing deposits need an off-line chemical clean first, which we include in the start-up phase.
Bleed-off at the recommended cycles meets DoE limits; we advise on neutralisation where a site discharges to a sensitive drain.
Other services
Design & Engineering
Cooling-load calculation, equipment selection and plant-room layout with piping and electrical drawings — before a single machine is ordered.
Supply & Installation
Chillers, towers, pumps, AHUs and panels delivered, rigged, piped and wired by our own site teams — one contractor, one warranty.
Testing & Commissioning
Flow balancing, approach and Δt checks, vibration and electrical tests — signed off in a commissioning report you can hand to an auditor.
Repair & Overhaul
Compressor swaps, motor rewinding, coil and tube cleaning, tower fill replacement and VFD retrofits — with a 48-hour diagnosis.
Genuine Spare Parts
Infill, nozzles, sprinklers, fans, motors, seals, controllers and compressors stocked in Mirpur for MHM, Carrier, TICA, Genius and Newin equipment.
Energy Audit & Retrofit
Measured kW/TR of your existing plant and a costed retrofit plan — VFDs, chiller sequencing, tower fan control, pump right-sizing — with payback you can verify.
