Biological

Nijhuis Water Technology offers a complete range of biological waste water treatment systems. The strength of Nijhuis is designing tailor-made solutions taking into consideration the total efficiency of a plant. In the process design the following aspects are considered:

Process Design:

• Pay back time
• Sludge production
• Sludge disposal route
• Available space
• Maintenance&Operation; Automation
• Comsumption of nutrients and energy

The purpose of biological treatment is to reduce the pollution in the waste water, which is indicated as:

• BOD: Biological Oxygen Demand
• COD: Chemical Oxygen Demand
• TOC: Total Organic Carbon
• N: Nitrogen
• P: Phosphorus

A biological treatment plant is using biomass to convert pollution into water, minerals and gasses, like carbon dioxide and nitrogen. Biological treatment is primarily aimed to reduce dissolved materials, like sugar, soap, organic acids, alcohol, starch, proteins etc.

Main characteristics of aerobic and anaerobic treatment systems: 

• low maintenance
• space saving
• low energy requirement
• complete automation possible
• pilot plants available
• quick pay back times
• computer controlled plant operation
• in-house knowledge and experience in biological treatment
• in-house knowledge and experience in integrated systems (pre-treatment,biological treatment, sludge treatment)
• installation, commissioning and training by Nijhuis specialists
• new product developments by our own R&D dept.
• worldwide after sales service
