Water Treatment Plants (WTP)
Water shaped around its purpose.
A change in the source can change everything downstream. A treatment system begins by understanding the water and the use it must serve.
Project vision
Raw water carries silt, colour, organic matter and germs. You can often see the problem in its colour or smell and taste it in the glass. A water treatment plant removes these in a fixed sequence: chemicals gather fine particles into heavier flocs, the flocs settle out, filters catch what is left, and disinfection keeps the water safe all the way to the tap.
Every source is different, so we start with a water analysis and your daily demand. From there we size each stage, choose the chemicals and filters, and add automation so operators can see and control the plant from one screen. Zeal covers design, supply, installation, commissioning and operation, with maintenance under an AMC if you want it.

Typical business & operational challenges
A typical operational situation
Seasonal turbidity, variable source quality and an unclear treated-water target complicate process selection.
Our solution
Water Treatment Plants (WTP) is considered around the actual duty, available inputs and operating arrangement. The scope starts with source analysis. It also considers intended-use criteria. It also considers treatment train selection. It also considers operating checks.
Our approach
Review seasonal samples
Set a design basis
Select clarification, filtration and disinfection as applicable
Commission against agreed checks
Features & deliverables
- Source analysis
- Intended-use criteria
- Treatment train selection
- Operating checks
Selection and inclusion are confirmed through the approved proposal and design.
Expected operational benefits
A clearer basis for source analysis and operating checks, supported by an operating approach suited to the application. Actual performance depends on the final design, conditions and operation.
Technology options & engineering basis
Select clarification, filtration and disinfection as applicable. Equipment, interfaces and operating requirements are selected after the input review.
Information to bring to the discussion
Source or process analysis, flow and load variation, target quality, space, utilities and operating constraints.
How it works, stage by stage
Intake
Raw water is drawn from the river, canal, reservoir or borewell, with screens to keep out debris.
Coagulation
A coagulant such as alum is mixed in rapidly, so fine suspended particles start to clump together.
Flocculation
Slow-turning paddles let the small clumps grow into larger, heavier flocs that can settle.
Clarification
Flocs settle to the floor of the clarifier as sludge, which is drawn off and dried for disposal.
Filtration
Sand filters catch the remaining fine particles and are cleaned regularly with a backwash of air and water.
Disinfection & storage
Chlorine is dosed to kill germs, and the clear water is held in a storage tank for supply.
Options
Conventional WTP
Separate flash mixer, flocculator, clarifier and gravity filters. Suited to larger flows and surface water with changing turbidity.
Packaged WTP
Compact, factory-built units for smaller flows such as campuses, hotels and remote sites, quicker to install.
WTP with ultrafiltration
A UF stage added after filtration where the use needs very low turbidity and a steady water quality.
Where it is used
- Towns & municipalities
- Housing societies
- Institutional campuses
- Hospitals
- Hotels
- Industrial process water
- Drinking water units

- The next step Start with source analysis, and define what success needs to look like. Discuss your application with ZEAL.
Questions before the next step
Which process is appropriate?
Process selection follows source-water analysis, intended use, flow and operating conditions. A universal treatment train is not assumed.
What is needed for an enquiry?
Source analysis, application details, available records, site constraints and the required delivery scope.
What do you need from us to design a WTP?
Your source of water, a recent water analysis, the daily volume you need and the space available. If you have no recent analysis, we can arrange one before we size the plant.
Can the plant run without a full-time operator?
Much of it can be automated with PLC control, so dosing, backwash and pumps run on their own. Someone still needs to check chemicals and readings, and we can provide operators under an O&M contract.
Do you upgrade existing plants?
Yes. We audit the plant, find the stage that is holding it back and upgrade it, whether that is dosing, filtration, disinfection or automation.
