Industrial Wastewater
There are three reasons why most companies consider on-site treatment of wastewater:
We carry out cost/benefit studies to show how to achieve the greatest benefit from the investment in effluent treatment. We design plants for the treatment of industrial effluents tailored to the requirements of the site and the industrial process, and we can arrange a complete service through to installation and commissioning of the effluent plant.
Wastewater from industrial processes can be difficult to treat. The cost of disposing of the effluent to the public sewer is determined by the volume, the polluting load, the suspended solids in the flow and the treatability of the effluent.
It may not be possible to treat the effluent with with municipal sewage, or it may be cost-effective to treat the effluent on site. The plant may be designed to reduce the strength of the effluent to a level suitable for discharge to the sewer, or to a standard suitable for discharge to the environment, or to optimise the balance between on-site costs and disposal charges.
Industrial wastewaters are typically much stronger than domestic sewage, and require a different approach if they are to be treated economically.
Many of the existing treatment plants are developments of municipal technology. It can be difficult to achieve the required effluent standards, and large amounts of sludge are produced.
Sludge disposal is becoming one of the greatest problems both for the Water Service Companies and industrial wastewater treatment plants. The available routes for disposal are reducing rapidly, and costs are escalating.
Modern aerobic treatment plants produce far less sludge with a smaller footprint on the site. Anaerobic plants produce minimal sludge with a by-product of methane which can be used in the upstream processes for heating or power generation.
