Water treatment engineered around the water you actually have
Waterwise Bangladesh helps homes, businesses and industrial facilities define practical treatment systems—from drinking-water filtration and RO to process water, WTP, ETP and STP requirements.

Core solutions
Choose by application, then design around the source water
Capacity, feed-water quality, required outlet quality, operating hours and maintenance conditions determine the treatment train.
Commercial
Commercial filtration & RO
For offices, restaurants, hotels, institutions and facilities needing more consistent capacity than domestic equipment provides.

Industrial
RO, WTP, ETP & STP
Assessment-led process selection for raw water, process water and wastewater treatment, with operation and maintenance considered from the start.

A treatment proposal is stronger when the problem is measured
Testing scope should match the source and intended use. An existing laboratory report can help identify design-relevant issues such as arsenic, iron, hardness, dissolved solids, pH or microbiological risk.
- Review the source and intended use
- Identify relevant water-quality parameters
- Translate results into treatment requirements
- Define capacity, operating hours and storage
- Plan pretreatment and maintenance
How a project starts
A clear design basis before equipment selection
Understand the requirement
Source, intended use, location, daily demand, peak flow and operating hours.
Review water quality
Use relevant test information rather than assumptions about a source or neighbourhood.
Define the treatment train
Clarify pretreatment, core process, storage, pumping, controls and waste or reject routing.
Plan operation
Backwash, consumables, cleaning, access, sludge and routine service are considered before handover.
Install & commission
Installation requirements are matched to space, utilities, drainage and the selected treatment process.
Maintain performance
Operating checks and service needs are built into the system discussion rather than treated as an afterthought.
Applications
Water treatment across homes, facilities and industry
Typical scopes are presented without inventing client names, capacities or performance results.
Drinking water
Filtration and RO planning for household and workplace drinking-water needs.
Commercial supply
Central treated-water systems for hospitality, offices and institutional use.
Process water
Pretreatment, filtration and membrane systems where water quality affects production or equipment.
Wastewater
ETP and STP planning based on wastewater characteristics, hydraulic load and discharge or reuse objectives.

Common questions
Frequently asked questions
How do I know what kind of water treatment I need?
Start with the source (municipal supply, tube well, surface water), the intended use (drinking, process, boiler feed, etc.) and, where possible, a water test report. Treatment selection follows the measured problem rather than the other way around.
Do I need a water test before getting a quotation?
A test is not always mandatory, but it makes the quotation far more accurate. Without it, sizing and treatment-stage selection has to rely on general assumptions about the source rather than your actual water quality.
What's the difference between RO, UF and standard filtration?
Standard filtration removes larger particles and sediment. Ultrafiltration (UF) removes finer suspended solids and some microorganisms but not dissolved salts. Reverse osmosis (RO) removes dissolved solids and salts as well, at the cost of higher pressure and some reject water. Which one (or combination) is appropriate depends on the feed water and the required output quality.
How often do filters and RO membranes need replacing?
This depends on feed-water quality, usage volume and the specific media or membrane installed — there is no single fixed interval. Heavier sediment or iron loads generally shorten filter life; regular monitoring of pressure drop and output quality is the reliable way to know when replacement is due.
What is the difference between WTP, ETP and STP?
A WTP (Water Treatment Plant) treats raw water up to a usable quality. An ETP (Effluent Treatment Plant) treats industrial process wastewater before discharge or reuse. An STP (Sewage Treatment Plant) treats domestic/sewage wastewater, typically using biological treatment. Each is designed around a different feed characteristic and objective.
Can an existing system be upgraded instead of replaced?
Often yes — pretreatment, membrane, or control upgrades can improve an existing system without a full replacement, depending on the current equipment's condition and the target improvement. This is assessed case by case.
How long does a typical installation take?
This varies significantly with system size and site readiness — a domestic RO unit is a same-day installation, while an industrial WTP/ETP/STP project depends on civil work, equipment lead time and commissioning requirements. Timelines are confirmed after the design basis is set.
Do you provide after-installation maintenance and support?
Yes — operating checks, consumable/media planning and preventive maintenance are treated as part of the system discussion from the start, not an afterthought after handover.
