Water Treatment Programme
Scale, corrosion and biological control for cooling towers, chillers and boilers — chemicals, dosing equipment, monthly analysis 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, the dosing hardware and the monitoring under one contract, with Finor chemicals blended for local water.
An MHM water engineer visits monthly, tests the circuit, adjusts 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.
Monthly testing & report
Hardness, alkalinity, conductivity, pH, residuals, dip slides — trended visit to visit.
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.

Water Treatment Programme for every part of the utility block
The product families our engineers design, install and service under this offering.
Electric Chillers
Air-cooled and water-cooled chillers from 10 to 850 TR, with genuine spares.
Cooling Towers
FRP counter-flow and cross-flow towers, 10–1500 TR, plus infill, nozzles, fans and motors.
Water Treatment Plants
RO, DM and softener plants, 1–150 m³/h, for boilers, dyeing and pharma.
Water Treatment Chemicals
Finor scale, corrosion and biocide programmes for 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.
Annual Maintenance Contract
Scheduled visits, water-side and air-side cleaning, chemical dosing and a written log after every visit — Basic, Standard or Comprehensive.
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.
