Ordinary dredging mining technology often has negative environmental impacts, including turbidity in water, harm to fish, water discharge, land contamination, and nutrient loss. In response, EHT Engineering Ltd. has developed the BioDeposit® Desilting Technology, utilizing a Submersible Chamber Complex (SCC).
Hydraulic Drive Technology:
-
SCC is equipped with a special hydraulic drive for precise pump performance adjustments.
-
Adjustments depend on cut layer thickness, movement speed, scraper bucket size, and rheological characteristics of the cutting mud.

The BioDeposit® Desilting Technology by EHT Engineering Ltd. offers a holistic approach to desilting, aiming to minimize environmental impact while efficiently addressing sediment-related challenges in water bodies.
Environmental Friendliness:
-
Operates without the suction of free water.
-
Works without rotation cutter heads.
-
Moves at an environmentally friendly speed of 5 cm per second.
4
Net Zero Requirements
-
Zero water suction.
-
Zero turbidity.
-
Low energy consumption (0.7-1.3 kW/m3).
-
Extracts bottom sediments with natural moisture (84-96%).
Operational Advantages
-
Assembly of the dredger at the lakeside.
-
Easy transportation of high-density slurry to distances exceeding 500 meters.
-
Minimal disturbance to swamps, fishes, and operational during spawning season.
-
No water stored in collecting bins, only peat and sapropel of natural humidity (85–90%).
