- Water Purification Stages -

Disinfection Stage:

PST Disinfection Systems ensures the first line of defense in water purification, eliminating harmful microorganisms and contaminants. Water disinfection is a critical initial step in achieving high-purity water standards.
We employ multiple, proven tailored disinfection application methods:
Chlorination – An effective microbial control for a wide range of raw water sources.
Ozonation – Powerful oxidation for chemical-free disinfection and improved taste and clarity.
Dosing Systems – A precise chemical dosing for targeted treatment, ensuring consistent quality.

By integrating these technologies, we provide a robust, multi-barrier approach that safeguards your downstream purification stages and guarantees regulatory compliance. PST delivers safe and reliable water.

Pre-treatment Stage:

Pretreatment plays a vital role in ensuring the efficiency, safety, and longevity of purified water generation systems. Our Ultrafiltration Systems are designed for maximum efficiency, tailored to your raw water characteristics and available in fully automated or manual configurations:
Media Filtration - removes suspended solids and turbidity, with optional automatic disc filtration.
Softener Systems - made with uniform particle size ion-exchange resin for optimal regeneration efficiency and minimal outlet hardness.
Carbon & Sand Filters - removes chlorine, taste, odor & fine particulates.
Ultrafiltration (UF) - fully automated plants, configured for dead-end or continuous bleed operation depending on feed water conditions.
Each system is built with FRP vessels, ensuring flexibility, efficiency & superior water quality.

Highly Purified Water:

PST specializes in RO–EDI technology for producing Highly Purified Water that meets stringent pharmaceutical standards.
Advanced designs offer chemical-free operation, hot water sanitization & optional steam for optimal purity and compliance with international stds.
RO–EDI Systems - standard packaged capacities from 250 LPH to 50,000 LPH, with custom designs for larger requirements.
Polishing Stage - RO permeate is further purified by the EDI unit to achieve PW quality water.
CIP Systems - independent, skid-mounted units for RO cleaning, ensuring consistent performance.
Hot Water RO - includes a heat sanitization system with options for steam or electric heating.
No-Chemical PW Generation - next-generation systems that eliminate chemical usage, reducing operational costs and environmental impact.
RO–EDI solutions combine efficiency, sustainability & compliance, ensuring highest standards of water purity for critical production processes.
