Technology

Overview

K-water GATe Water Combine is a technology to timely and directly remove algal blooms present in rivers and reservoirs through coagulating and floating them with physical and chemical methods

  • With this technology, it’s possible to remove & control agal blooms over wide areas, including a specific river system by coagulating and floating them using an agal remover, and then selectively removing them using an agal removal unit.

Features

  • Highly lightweight assembly type and very good in terms of mobility and applicability (possible to carry this combine with one 5-ton vehicle)
  • No separate need for berthing facilities
  • Excellent in terms of readiness (possible to carry this combine where agal blooms happen within 3 hours, and then remove them within 4 hours since)
  • Possible to control & remove over wider areas and excellent in terms of economic feasibility and environmentfriendliness

Functions

  • Mobilize & carry

    • Improvement of stripping device to separate off collected agal blooms and other impurities

Effects

  • Develops onsite practical technologies to proactively respond to agal blooms, and thereby resolve the problem of agal blooms in large rivers and reservoirs
  • Develops & provides next-generation pollution purification technologies by changing waters where agal blooms happen to a brand-new concept of resource production base
  • Used as a tool to manage water pollution beforehand through onsite practical optimization, and improve the environment of waterfronts (amenities)
  • Advances basin & water quality management practices through applying BT and ET convergence technologies
  • Development of environment-friendly technologies to control agal blooms → Development of K-water’s own source technologies to relevant on-shore & offshore markets

Applications

  • Applied to the removal of agal blooms in the mainstream of Hapcheon & Changnyeong Weirs and its tributaries (some 1.7 tons)
  • Applied to the monitoring of where agal blooms occur at Nakdong R. Bonpo Intake Station & removal of pollutants flowing in the tributaries (0.9 ton)
  • Applied to the removal of agal blooms in Chuso-ri Waters of Daecheong Dam (2.9 tons)
  • Utilized as response technology to agal blooms in large river basins
