Wastewater Treatment For A Better Environment
Nijhuis Water Technology aims to create a better Environment by cleaning WATER streams to the effluent quality you require for discharge to sewer or river. In our delivery program we have a complete range of wastewater solution products which can be combined to your specific solution and to meet your specific requirements for wastewater treatment.
The first step in wastewater treatment is primary treatment, removal of solids which results in reduction of pollution load in your wastewater. Depending on your effluent you might require either a screen, a flotation system or a flocculation & flotation system. If you discharge your water into a sewage system a primary treatment can be sufficient to meet the effluent requirements for treatment of water.
Discharging to the environment, for example a river or irrigation requires a secondary treatment step, biological treatment. Nijhuis Water Technology can select the most economic treatment system for you based on your type of wastewater, based on the actual requirements and local circumstances.
In some areas biologically treated water requires a tertiary treatment step, polishing, due to very tight requirements. Effluent after a tertiary treatment step is very clean, so clean that the step to reuse of your water can be made.
During treatment of wastewater, sludge is produced which needs to be disposed. Depending on your local requirements we have a range of sludge treatment systems to minimise your waste stream.
Depending on your requirements a selection of our primary treatment systems will be either the first step of your treatment or the complete solution.
Secondairy treatment systems make use of bacteria to remove dissolved materials from your waste water. In general you devide these systems into two groups.
During treatment of waste water and wastes, sludge is produced which needs to be disposed of in order to diminish the disposal costs.
