Prefabricated WTP

Factory-built water treatment systems designed for faster installation and reliable operation.

Prefabricated Water Treatment Plants

Prefabricated Water Treatment Plants integrate the required treatment equipment into factory-assembled skids, modules or containerised packages before delivery to site.

Depending on the source-water quality and required treated-water specification, a plant can incorporate filtration, softening, membrane treatment, chemical dosing, disinfection, storage interfaces, pumps, instrumentation and automation within a coordinated system.

Hydroxy configures each prefabricated plant according to: Source Water + Required Capacity + Treatment Objective + Product-Water Quality + Site Conditions

Prefabricated systems are particularly suitable where projects require faster installation, compact footprint, reduced onsite fabrication or future modular expansion.

Prefabricated Water Treatment Plants

Building and integrating more of the treatment plant in a controlled fabrication environment can simplify site execution and improve equipment coordination. Key advantages include:

  • Factory-Assembled Construction
  • Reduced On-Site Fabrication
  • Faster Installation & Commissioning
  • Compact Footprint
  • Skid-Mounted or Containerised Options
  • Pre-Integrated Piping & Equipment
  • Integrated Electrical & Controls
  • Modular Capacity Expansion
  • Easier Transportation
  • Suitable for Remote Locations
  • Reduced Civil-Work Requirements
  • Simplified Plant Integration
  • Automatic Operation, where required
Key Design Parameters

Prefabricated water-treatment plants should be selected according to the actual source-water analysis and required final-water quality. Typical design parameters include:

  • Source Water
  • Required Flow / Capacity
  • Turbidity
  • Suspended Solids
  • TDS / Conductivity
  • Hardness
  • Alkalinity
  • Iron
  • Manganese
  • Silica
  • Chloride
  • Organic Matter
  • Microbiological Quality
  • Feed-Water Temperature
  • Required Treated-Water Quality
  • Recovery Requirement
  • Operating Pressure
  • Available Footprint
  • Operating Hours
  • Automation Requirement
  • Electrical Supply
  • Future Expansion Requirement
Prefabricated Does Not Mean Standard Water Quality

Two prefabricated plants with the same capacity may require very different treatment processes. A groundwater source with hardness and iron does not require the same treatment train as surface water, brackish water or seawater.

Hydroxy therefore configures the plant around the actual water analysis rather than supplying a single universal package.

Prefabricated Drinking Water Treatment Plants
Integrated treatment systems for safe and reliable drinking-water production.

Prefabricated drinking-water plants combine appropriate treatment stages according to source-water conditions. Depending on the requirement, the package can incorporate:Clarification → Filtration → Carbon Treatment → Disinfection → Final Water Additional treatment can be integrated where source-water chemistry requires it.

Typical Applications:

Communities, hotels, resorts, hospitals, schools, institutions, commercial developments and remote facilities.

background
Prefabricated Reverse Osmosis Plants
Factory-assembled membrane systems for dissolved-salt reduction and water purification.

Prefabricated RO plants integrate pretreatment, high-pressure pumping, RO membranes, instrumentation and automatic controls into a compact skid or modular system. The configuration is selected according to feed-water TDS, required recovery and permeate-water quality.

Typical Applications:

Commercial water treatment, industrial process water, drinking water, boiler make-up water and high-quality utility water.

background
Prefabricated Brackish Water RO Plants
Packaged desalination systems for groundwater and moderate-to-high TDS water.

Brackish Water RO plants are engineered for source waters where dissolved mineral content is too high for conventional filtration alone. The system can integrate pretreatment, antiscalant dosing, membrane filtration, flushing and process controls.

Typical Applications:

Borewell water, brackish groundwater, hotels, industries, remote facilities and commercial water production.

background
Prefabricated Ultrafiltration Plants
Compact membrane filtration for turbidity, colloids and microorganisms.

Prefabricated UF plants use membrane modules as a physical barrier to reduce suspended solids, turbidity and microorganisms while allowing dissolved salts to remain. Systems can include automatic backwashing, chemical cleaning and PLC-based operation.

Typical Applications:

Surface water, drinking-water pretreatment, RO pretreatment, industrial water and process-water filtration.

background
Prefabricated Water Softening Plants
Factory-integrated ion-exchange systems for hardness reduction.

Prefabricated softening plants contain resin vessels, control valves, brine preparation, piping and associated controls within a coordinated treatment package. Automatic systems can manage service, regeneration and rinse cycles according to operating requirements.

Typical Applications:

Hotels, hospitals, laundries, cooling systems, boiler pretreatment, commercial facilities and industrial process water.

background
Prefabricated Demineralisation Plants
Integrated ion-exchange treatment for low-mineral process water.

Prefabricated DM plants combine cation and anion exchange stages and, where required, final mixed-bed polishing. The system can include regenerant preparation, chemical dosing, piping, instrumentation and automatic regeneration controls.

Typical Applications:

Boiler make-up water, process water, power applications, manufacturing and industrial utilities.

background
Prefabricated High-Purity Water Plants
Multi-stage treatment packages for demanding final-water quality.

High-purity plants integrate multiple purification technologies where standard filtration or single-stage RO cannot achieve the required water quality. Depending on the application, systems can combine: Pretreatment → RO → Secondary RO / EDI / Ion Exchange → Final Polishing

Typical Applications:

Pharmaceutical utilities, laboratories, electronics, manufacturing and specialised industrial processes.

background
Modular Expandable Water Treatment Plants
Treatment capacity designed to grow with water demand.

Modular plants use repeatable treatment blocks that can operate independently or in parallel. This allows initial capacity to match current requirements while providing a practical route for future expansion.

Typical Applications:

Phased developments, growing communities, industrial expansions, resorts, campuses and decentralised water infrastructure.
