Efficiency in Waste Water Treatment for Local Authorities
The biochemical cleansing and waste water treatment can be solved ideally with modern technology.
A comparison of different processing methods shows that the technological and construction elements for a solution in waste water; the quality of the sludge and the stability of the processes vary substantially. Hence realistic investment in waste water technology for communal use should be subject to the following criteria:
- investment cost (construction & technology) in relation to site size
- flexibility on costing (energy, sludge treatment, staff & sundry expenses)
- ROI (return on investment)
- smell, sludge stability
- stable results where hydraulic & logistic expenses are variable
- breakdown, maintenance time & incidence of repair
Intelligent Control of Substances
The activated sludge process relating to sludge is one of the most effective methods used for waste water treatment by Local Authorities. With this method, any plant designed in accordance with regulation ATV A 131 can be catered for.
In comparison with the percolating filter method, where bacteria and other organisms are immobilised in controlled surfaces, the degradation process allows these to be irradiated naturally. To achieve an ideal reduction of carbon (COD), nitrogen (ammonia, nitrate) plus phosphate compounds, a proper aeration - endogenous conditions in the (nitrification/denitrification) must be provided in every phase of the operation. Only then can various microorganisms function efficiently.
