ISSUES FACED BY ELECTROPLATING ENTERPRISES

1. High investment and treatment costs

Wastewater contains high levels of heavy metals and salts, leading to massive investment and treatment costs. The volume of generated sludge is also significant.

2. Waste of raw material resources

Wastewater from the electroplating process contains large amounts of heavy metals such as chromium, nickel, gold, silver, copper, and zinc, along with industrial acids and salts. The procurement cost of these materials accounts for a large proportion of the total production cost but is wasted as effluent.

3. Lack of technical support

After the investment phase, many factories using foreign machinery and technology face numerous difficulties in obtaining timely technical support during subsequent operations, especially when incidents occur.

NGO’S ELECTROPLATING WASTEWATER TREATMENT SOLUTIONS

Recovering precious metals from wastewater to reuse in production, while simultaneously reducing the treatment load at the wastewater treatment plant, making the system more cost-effective
Minimal chemical usage to remove heavy metals and other pollutants from water, reducing chemical costs, making operational work less laborious and toxic, reducing the volume of generated sludge, and limiting secondary pollution. By not using chemicals and not depending on pH conditions to coagulate each metal component, NGO’s solution allows the treatment of all wastewater streams generated in the plating process without stream segregation for projects with limited installation space, thereby minimizing storage tanks and the complexity of the treatment process, and simplifying the wastewater collection system from production segments

NGO’S ULTRAPURE WATER SUPPLY TREATMENT SOLUTIONS

Feed water (Municipal water) is pumped through initial treatment stages including multi-media filtration (sand, activated carbon) and softening.
Softened water is then processed through security filters before entering the 1st Pass RO system.
1st Pass RO water is directed into a storage tank and fine-filtered once more before passing through the 2nd Pass RO and purification filters.
After passing through UV sterilization and detailed filtration stages, the water is stored in the purified water tank for production use.
A branch of the process continues through the EDI (Electrodeionization) stage to generate the ultrapure water (UPW) required for electronic component manufacturing processes.
Finally, both ultrapure and purified water are stored in tanks, ready to supply the production process.
