EKOTON – Multi-disc Dehydrator

About the Company:

“Ekoton” Company was founded in 1995 by wastewater treatment engineers. The Company started its production activity from simple polymer products with just eight employees. In 1999 the Company had mastered manufacturing of its first mechanized equipment. From year to year EKOTON has increased its own production capacity and involved new professionals to grow their team. Today EKOTON Industrial Group includes three main production factories plus engineering centers, serving customers in more than 30 countries worldwide. EKOTON’s product range covers most wastewater treatment and sludge treatment processes. Their team is constantly developing the equipment they produce, offering innovative and reliable solutions to water industry professionals.

About the Solution:

The Multi-disc Dehydrator operates in continuous mode. Influent is pumped from the external process or storage tank into the process tank. A mixing system located in the process tank prevents stratification.

The influent is then pumped to the dosing tank, and then through a calibrated overflow to the flocculent tank. Excess influent from the dosing tank returns into the process tank through a control overflow union to allow for continuous steady flow.

A polymer solution is supplied into the flocculent tank and is mixed with the influent by means of a mixer to form floccules. Then the influent enters the dewatering drum(s) and is conveyed with the screw(s) to the dewatering zone. As it moves along the drum, the material is dewatered forming a cake and filtrate which is drained through clearances between the rings.

As the screws rotate, the movable rings move parallel to the fixed rings to provide self-cleaning of the filter pores. In addition, the external drum surface is flushed with water.

The drum exit is partially overlapped by a movable divider. By changing the distance between the drum exit and the divider, the back-pressure on the cake moving inside the drum can be regulated, which determines the degree of sludge dewatering. The dewatered material drops into the receiving hopper of the transporter by gravity feed. The dewatered cake produced by this dehydrator can reach as low as 75-82% residual moisture at an average flocculent dose of 1.5-3.5 kg/t of dry matter.

Solution Strengths, Weaknesses and Critical Indicators

Chemical flocculation technologies remove the non-dissolved particles from the waste stream typically resulting in irrigation quality “tea water”:

  • Produces a clay like cake which is high in phosphorus and with significant amounts of organic nitrogen.
  • Supported technologies include belt presses, centrifuges, dissolved air flotation systems and others; all requiring flocculants to achieve high rates of solids removal
  • There is significant variation of chemical and energy use depending on site and by technology
  • There is significant variation of operational intensity depending on site and by technology
  • There is significant variation of cost depending on site and by technology
  • Proven technology for nitrogen recovery, phosphorous recovery, storage reduction, GHG reduction, and odor control

Newtrient Comments/Opinions:

Newtrient is currently working with EKOTON Industrial Group to evaluate this technology and to collect information on its use in the dairy industry. At this time there are no installations on dairies in North America. Once the systems is installed on a dairy it will be evaluated on the Newtrient 9-Point Scale.
