• Contaminants such as Cryptosporidium, Cysts, Turbidity, heavy metals are successfully removed by the filter process.

What quantity of water does the MECKOW EPA20 produce?

• The MECKOW EPA20 is capable of producing 20m3/h of potable water. Maximum treatment capacity may vary depending on source water quality.
• This plant can also be used to increase the capacity of any existing systems.

What water source can the MECKOW EPA20 use?

• The MECKOW EPA20 can produce potable water from any kind of raw fresh water source.
• It can also remove any iron, manganese and sulphur that may be present in groundwater sources.

• The estimated installation time is 15 days.

How does the MECKOW EPA20 process work?

• The treatment process consists of conventional coagulation, flocculation, sedimentation, filtration and disinfection.
  • Coagulation: Rapid mixing takes place in the raw water inlet pipe, where the chemicals are fed directly into the pipe via a dosing system, 1 m upstream from the plant inlet.
  • Hydraulic flocculation: The MECKOW EPA20 has a two stage hydraulic flocculation process. Here the water is gently mixed as it flows past vertical baffles placed in the flocculation channels.
  • Sedimentation: The MECKOW EPA20 has one high rate settling tank, with settling tubes inclined 60° towards the horizontal plane.
  • Rapid filtration: The plant has four declining rate rapid filters, with an automatic backwash system.
  • Dosing system: Chemicals used in the treatment process are metallic coagulants (like aluminium sulphate, ferric chloride, etc), alkalinity regulators and disinfectants.
