3. 1. COMPANY INSTRUCTION Greeting Hello!
Since established in 2009, Bokju has made all efforts to supply only clean, healthy and sustainable water tank and developed an eco-friendly and modern type of water tank, CW Panel Lining water tank and CW Panel-combined water reservoir.
The CW Panel lining and CW Panel-combined water reservoir had been already designated as an excellent procurement item respectively to be widely acknowledged for their excellence and have obtained an honor of being selected as a supported enterprise to advance into the overseas procurement market. And we also were honored to win “Korea small and medium enterprise innovation grand-prize,” 2012.
I think that serving clean water for next generation is my mission and promise to try to do it with my executives and staffs as one of the leading companies in water industry.
Thank you.
Taeyoung Cho

9. 2. PRODUCT INTRODUCTION The problems of existing products
Stainless water tank - upper part corroded by chlorine gas, rust on welding part
Peeled off painting part and Leaking water out of cemented structure
Peeled off Epoxy coating on surface & Corrosion
→ Detection of Bisphenol-A

10. “SPE PANEL” 2. PRODUCT INTRODUCTION What is the SPE Panel? LDPE LDPE
Contact surface of water
LDPE
Contact surface of water
Stainless
Attaching concreted structure
Stainless
Attaching concreted structure
* SPE PANEL : LDPE sheet and stainless steel sheet are layered panel

11. 2. PRODUCT INTRODUCTION Structure of SPE Panel LDPE LDPE Stainless
Why use SPE panels?
SPE Panel : LDPE sheet and stainless steel sheet are layered panel.
SPE panel attached to a concrete or cement reservoir and water tank.
So, the surface of the LDPE sheet touches the water, and the stainless steel sheet surface touches the concrete.
-> Therefore, SPE panel has all the advantages of LDPE and Stainless.
LDPE Sheet’s advantage : Hygienic, non-corrosive, semi-permanent
STS 304 (stainless steel)’s advantage :
Durable, semi-permanent

Advantages of SPE Panel
SPE PANEL
Hygiene
Economical efficiency
Durability
- Economic effect by minimizing
the cost of maintenance and repair
Harmless, non-toxic, odorless
Clean water tank without the release of environmental hormones and heavy metals
- No corrosion and semi-permanent use
- Defects occurrence is less

13. 1 2 3 4 5 6 2. PRODUCT INTRODUCTION Advantages of SPE Panel SPE PANEL
* Excellent Both sides Compression and Impact strength semi-permanent lifespan 2
* Double waterproof structure to maintain waterproofing as STS is substitute for damaged PE sheet of surface 3
* Strong corrosion resistance to chemical like chlorine * No harmful substance and Great hygiene(PE Sheet) 4
* Easy maintenance and Low repair costs 5
* No Product damage from External Factors of rusty pipe and temperature changes 6
* Various applicable panel
– The concrete reservoir, Chemical tanks, Sewage tanks

14. Adhesion method or Film type
2. PRODUCT INTRODUCTION
Adhesion method or Film type
Comparison of water-proofing products
Double water proofing
- Even when PE layer is damaged, STS plays a role of water-proofing
No interference structure condition (ex: Crack)
No transferal corrosion from foreign substances in pipeline
Partial repair is easiest and cost is lowest
- Simply banding a PE to repairing area - 20% down less than the previous
Construction
100% Perfect waterproofing
- Because it is scientifically tested(spark test) during construction, Defects are found before filling with water
SPE Panel Lining
Other materials
Because depend on visual inspection, Defects are found after filling with water
Fixing SPE Panel by using anchors on concreted structure
Partial repair impossible and high cost
Epoxy, PE sheet, Tile type : Leakage test and reinforcement work is difficult
STS : Acid cleaning costs
When Simple repair, water cut-off necessary
SPE Panel Lining
100% Perfect waterproofing

Construction
Fixing SPE Panel by using anchors on concreted structure
Film type or simple adhesion method
Partial repair is easiest and cost is lowest
- Simply banding a PE to repairing area - 20% down less than the previous
No water cut-off
- When regular cleaning, it can be repaired
No water cut-off
- When regular cleaning, it can be repaired
Maintenance
Maintenance
No interference structure condition (ex: Crack)
No transferal corrosion from foreign substances in pipeline
Film and tile type : loss of waterproof function
STS : Corrosion occurrence of reservoir back side and transferal corrosion
Double water proofing
- Even when PE layer is damaged, STS plays a role of water-proofing
Adhesion method or Film type

15. 2. PRODUCT INTRODUCTION Comparison of water-proofing products
Durability
Hygiene
Economic Feasibility
The Lowest Life Cycle Cost
- Installation easiness, Durability, Maintenance, Reuse
(More than 60% savings compared to Epoxy)
Semi-permanent material life (40~50 years)
- STS,PE durability → more 50 years
It is not affected by chlorine
SPE Panel Lining
Other materials
STS type – It is most vulnerable to chlorine
Epoxy type → 3 ~ 5 years
STS type → 10 ~ 20 years
(Chlorine, back side corrosion)
Tile type → 5 ~ 10 years
Hygienic and environmentally-friendly materials
Reuse possible, No corrosion, Hazardous substances are not eluted
Epoxy type → Environmental hormone
(Bisphenol A)
FRP type → Glass fiber elution, waste disposal
STS type → Heavy metal elution
Because Insufficient durability and maintainability, Life Cycle cost is Increase
(At least two to three times of SPE panel)
