Water treatment technology/plant plumbing

Taiyo Sangyo Co., Ltd.

Membrane filtration system• Custom-made water treatment system: Our membrane filtration technology enables
us to fulfill our customers’ needs, from pure waterproduction through to waste water recycling

Characteristics
1. Membrane filtration water purification system
We have been engaged in designing and manufacturing RO (reverse osmosis) membrane water treatment systems
since 1979. The technology and knowledge we have accumulated enables us to design and manufacture water
treatment systems using a filtration membrane (for reverse osmosis water and concentrated water production,
seawater desalination, effluent treatment, etc.).
2. Plant plumbing works
We put our stainless welding technology to full use to meet a whole range of customer needs for equipment installation,
including on-site plumbing work and peripheral facility reconstruction & maintenance that make use of our technologies
in high-pressure piping, sanitary piping and other plumbing work in the chemical and food plant industries.
3. Metallic components machining/assembly
We can provide a flexible service to meet our customers' needs even for a single item.
4. Local corporation in Vietnam (Dewx Vietnam Co., Ltd.)We also have a base in Vietnam.
