Chemical dosing solutions for a new-build sewage plant

During construction of a sewage plant in Sichuan, China, the operator required a dosing pump control system in order to precisely manage chemical injection as part of the site’s state-of-the-art design.

The plant – an 80-million-yuan ($11-million) development expected to process 20,000 m³ of sewage per day – was to incorporate advanced technology for the handling of complex applications such as anaerobic-anoxicoxic (AAO) including a deep bed denitrification filter.

Meanwhile, a key requirement during planning was the protection of water quality and the maintenance of a healthy ecological balance within local water bodies.

For this, SEKO was approached to supply a dedicated solution for sodium hypochlorite, phosphate remover and carbon-source dosing at various stages of the process.

Following an initial site assessment and collaboration with the operator, SEKO recommended its motor-driven Spring series pumps and Elektra control units as the ideal solutions to meet all the operator’s needs.
