Sewage Treatment · Wastewater Treatment Plant

Water polluting is getting worse because of destruction of the natural environment and water ecosystems caused by rapid economic development and industrialization. Therefore, Halla Energy &Environment has developed an advanced wastewater treatment process and built environment friendly underground wastewater treatment plants near new urban areas for the reuse of recycled water.
The characteristics of industrial wastewater can vary according to the substances contained and the production process. So, it is important to perform a field study for an analysis of the pollution source and selection of the most efficient treatment process.
Halla Energy &Environment has extensive references for designing, constructing and operating wastewater treatment plants in the areas of pulp materials for Industrial waste water, waste water from incineration, leachate from landfills, livestock manure.

Automated Water Purification Process / Riverbed Filtration & Seawater Intake System

Halla Energy &Environment is the first company in Korea that receives from the Ministry of the Environment the New Environmental Technology (ENVI-SYS) certification for its improved automated water purification efficiency method. With this technology, we are focusing on improving and retrofitting old and new water purification plants. The riverbed filtration process extracts water from the vertical well from the river shoreline. The vertical well connects with horizontal (lateral) screen pipes that are the intake screens for filtrated river water through the riverbed aquifer layer. This process secures an indirect water intake source and helps to improve river water quality as well as to insure river water is maintenance.
The seawater intake system indirectly intakes seawater that is naturally filtrated through the sand layer of the sea. Halla Energy &Environment has developed a beach-well methodwith high efficiency in terms of operation and management that has simplified the pre-treatment process and reduces construction and maintenance costs
