AEROBIC DIGESTER W11

Mã sản phẩm: W11

The continuous activated sludge process has been successfully employed in public health engineering installations for nearly a century.

The Armfield bench top Aerobic Digester is designed as a comprehensive study facility of this biological water treatment process.

A synthetically prepared waste water may be used to gain a working knowledge of the operational parameters and purification efficiencies.
