Primary Treatment

Depending on the specific wastewater characteristics, Apateq customizes primary treatment methods that are either proprietary developments or components procured from quality suppliers.


Apateq utilizes organic or inorganiccmembranes in its proprietary processes to construct wastewater plants and oil-water separation systems.  Consequently, the technology offers several advantages:

  •  minimized membrane surface fouling
  • increased process efficiency
  •  significant cost reduction
  • low energy consumption
  •  effortless cleaning procedure with long intervals in between cleanings
  •  substantial extended membrane life time 

Sludge dewatering

Acting as a gravity thickener within the Apateq systems, a sludge storage tank removes solids in the primary treatment, and sludge particles are separated by the membranes.

 The sludge from the biological stage is pumped into the sludge storage tank via a motor valve. A pressure probe measures the sludge level in the sludge tank and controls the motor valve. Next, without adding flocculants or precipitation chemicals and with long lifetime and smooth operation, a bespoke compact sludge dewatering device thickens the sludge to a level of 17% DS or greater.

When used in containerized wastewater treatment plants to avoid any gas release inside of the container, an integrated air management system is installed. Using sample ports installed on the tank outside wall, the operator can evaluate the current level of the sludge blanket in the tank. 

Air injection

Depending upon the plant’s capacity, venturi elements or air blowers are used to aerate the biology. Taking advantage of the existing recirculation flow to save associated air blowers or compressors, smaller systems will incorporate venturi pipes and save additional operational energy.

For air injection, Apateq plants, larger than 25 m³/day, use state-of-the-art injection blowers. When possible, venturi elements will be installed. To prevent mechanical downtimes, the plants’ critical systems are designed with redundant air blowers and pumps. Therefore, if one component fails, the back-up device will provide continuous operation.
