Esmil DAF Unit

We are happy to inform our colleagues about the next Esmil’s successful installation in Chile.

In 2017 the dissolved air flotation complex for local wastewater treatment of a fish processing plant in Los Lagos region had been installed by our partner Aguas Sipra S.A., including such equipment as:

  • Fine drum screen RMB TP 6/6,
  • DAF unit FT-25,
  • Tubular flocculator,
  • Saturation system for white water preparing,
  • Pumps for the complex,
  • Automation system for the complex, including control system with sensors.

The Esmil DAF complex has a customized design for the particular application. The object’s features required high amounts of dissolved air to be fed into wastewater to tackle high loads of contaminants. The complex’s capacity is 18 m3/h.

The efficiency of the complex is as follows:

Los Lagos, Chilie Project Data

ParametersInput concentration, [mg/L]Efficiency, [%]Output concentration, [mg/L]
Total suspended solids (TSS)6,54195327
Biochemical Oxygen Demand (BOD5)10,696406,418
Nitrogen, Total Kjeldahi (NTK)72620581
Oil and Grace (O&G)9759098
Dissolved solids (DS)816032

As a result the customer got a specially designed wastewater treatment system which is fully solves its  effluent requirements. In this project Esmil confirms the advantages of it’s developed DAF technology as well as the appropriateness of approach to use just the highest quality components available. The equipment operates steadily well, which is really important for such a distant projects.
