These systems are widely used for water sterilization, industrial disinfection, and corrosion mitigation in power plants, municipal facilities, ships, and offshore platforms.
Key Sub-Types & Models
a) Plate-Mesh Type Electro-Chlorination System
-
Principle: Uses multiple plate and mesh electrode structures for efficient electrolysis of saline water.
-
Applications: Water disinfection, seawater conditioning, plant effluent treatment.
-
Representative Models:
-
SRSM-30/6 — Small-scale production (approx. 0.57 kg/h Cl₂)
-
SRSM-120/6 — Mid-range capacity
-
SRSM-320/6 — Higher production output
-
SRSM-300/3, SRSM-330/1 — Alternative configurations for different flow rates
-
SRSM-400/1 — Enhanced capacity for larger installations
-
b) Tubular-Plate Type Electro-Chlorination System
-
Offers improved hydraulic performance and ease of maintenance. Suitable for continuous large-scale operation in industrial water treatment facilities.
c) Drinking Water Disinfection System
-
Converts saltwater into a sodium hypochlorite solution with concentrations up to 10,000 ppm for potable water safety applications.
2. Water Treatment Systems
These systems focus on the purification, desalination, and disinfection of seawater and inland water sources. They serve municipal water plants, industrial facilities, and shipboard freshwater generation.
Primary Systems
-
Seawater Desalination System: Employing reverse osmosis (RO) for seawater conversion to fresh water.
-
Demineralization Systems: Ion exchange or membrane solutions for high-purity industrial water.
-
Municipal Drinking Water Systems: Ensuring treated water meets health and safety standards.
-
Industrial Water Clarification & Filtration Solutions: For process water in factories and power plants.
