Containerized Wastewater Treatment

Mobile containerized wastewater treatment plants

Mobile sewage treatment plants and mobile wastewater treatment plants are a highly effective method of rapidly providing an onsite wastewater treatment / sewage treatment infrastructure anywhere.

Containerised / mobile wastewater treatment plant components

A mobile wastewater treatment plant consists of sea containers with wastewater treatment equipment preinstalled into them. This allows for simple transport across the world. All stages of the treatment process can be preinstalled into a container. These typically include the following elements;

  • Mechanical screen – the aim of the mechanical screen is to remove all of the coarse solids from the influent. The waste material is then stored for disposal.
  • Aerated buffer container tanks – these tanks mix and equalise the incoming sewage to ensure the wastewater entering the reactor container is well mixed and homogenized.
  •  Biological reactor container – this is the reactor container with an aeration systems and fixed bed media. The main biological treatment process occurs here.
  • Clarifier – a containerised clarifier incorporating lamella plates facilitates clarification and settlement of the final effluent.
  • A technical container – this houses all aeration equipment, control panels and other mechanical and electrical components

In addition to these main components, there are a variety of additional modules that can be added to any containerised wastewater treatment plant or mobile wastewater treatment plant. These include, but are not limited to the following;

  • A forward feed pump station module – this can collect the raw sewage from various locations onsite and then pump the sewage into the mechanical screen.
  • Sludge storage containers – these extra sludge storage containers allow for long-term storage of the waste screened material onsite where regular collection and disposal poses a difficulty.
  • Sludge dewatering containers – where sludge is to be collected and disposed of immediately, a sludge thickening unit can be supplied to de-water and thicken the sludge to facilitate low cost removal.
  • Nutrient removal modules – these modules can incorporate chemical dosing to remove nutrients such as phosphorous in sensitive areas.
  • UV disinfection modules – where final effluent discharge is to a senstitive location, or where reuse is needed then UV modules can be incorporated into the design.

Any wastewater type

Mobile wastewater treatment plants and sewage treatment plants are highly versatile. Use of mobile container plants is not just limited to domestic type sewage. They are also ideal for installation for the following types of application;

  • Mobile worker camps
  • Drilling rigs
  • Construction sites
  • Asylum / refugee camps
  • Large events or gatherings
  • Industrial wastewater treatment
  • Landfill leachate treatment
  • Development sites where the system location may need to change in the future
  • Sites where there is a flood risk
  • Sites where a  temporary solution is needed [i.e maintenance of municipal plants]

Flexibility and modular design

Containerized mobile wastewater treatment plants have ultimate flexibility, as additional containers can be added to the overall system or removed from the overall system to cater for any change in volumes entering the plant. Where effluent standards change then modules can be added to meet any effluent standard.

Rent or buy

Containerised mobile wastewater treatment plants are available to buy where they will be installed for an extended period of time, or where they will be part of the main infrastructure onsite. However, containerised units are also available to rent or lease where this is a more cost effective solution.
