H+E provides wastewater treatment systems for photovoltaic industry processes, such as wafer production (on silica) and cell production (on silica and glass), which require large amounts of process water.

The company carries out complete management of the various water streams to and waste streams from all production stages.

Process water systems ensure constant water quality independent of the actual recycling rate; high water recovery rate; easy operation; and easy system extension if the quantity or quality needs to be extended.

Wastewater treatment systems reduce sludge disposal and save manpower; Rinse-water that cannot be recycled is collected separately and treated. Process chemical concentrates are collected separately and treated externally.

Recycling technologies include activated carbon, ion exchange, UV irradiation and membrane process systems.
