BLUEWIN CO., LTD.
About
BLUEWIN CO., LTD., established in 1989 and based in Seoul, supplies dewatering equipment and turnkey treatment plants, holding roughly 70 percent of Korea's market for primary dewatering machinery at water and wastewater plants. Its signature ELODE electro-osmosis dehydrator pulls free and absorbed water from sludge using electric fields, reaching 40-60 percent dry solids alone and up to 90 percent when paired with the NVD natural vacuum drying system, at 0.25-0.45 kWh per liter removed. Other machinery includes Royal-Decanter centrifuges - over 3,000 units at 1,000 sites - screw, belt, and vacuum filter presses, drum thickeners, the HEBD low-temperature belt dryer, 2P/3P separators, GJ-R bubble systems, fiber filters, and polymer dosing gear. A staff of 180 with 45 professional engineers supports R&D above 5 percent of sales, exports near $65 million yearly, and installations in 63 countries.
Key Products
World-first commercial electro-osmosis dewatering system that uses electric fields to extract free and absorbed water from sludge, achieving 40-60% dry solids with 0.25-0.45 kWh/L energy consumption, no dust, odor, or polymer required
Vacuum drying system paired with ELODE that achieves up to 90% dry solids (10% moisture) and 83% sludge weight reduction through low-temperature evaporation under vacuum conditions
Belt-based sludge drying system operating at low temperatures for energy-efficient reduction of sludge volume and moisture content
Centrifugal solid-liquid separation equipment with over 3,000 units installed worldwide, known for low energy consumption, low spare parts cost, and high dewatering ratios
High-compaction auger-type sludge dewatering machine offering low power consumption, low noise, and low water usage for thickening and dewatering applications
Continuous belt-type sludge dewatering machine using gravity drainage and mechanical compression between two filter belts
Vacuum-assisted filtration system for enhanced dewatering of sludge through vacuum pressure applied to filter media
Rotary drum device for sludge thickening that drains free water through a rotating screen cylinder to increase solids concentration before dewatering
