Through our knowledge database we give qualified counselling based on documented experiences and the financial advantages you achieve using the KSA system for volume reduction. As an inspiration below we have shown various service jobs where our customers with great advantage use the KSA system.
The core of sludge dewatering is to separate solids and water. The functioning is illustrated in the 4 drawings below. The example is based on emptying of a septic tank. The drawings can analogues be transferred to emptying of grease separators, petrol and oil separators or to many other service jobs.
Step 1 : The contents of the septic tank are sucked up into the sludge tank.
Step 2: The contents of the sludge tank are pumped up into the dewatering tank. During pumping polymer is added.
Step 3 : The reject water is lead back to the septic tank. This secures optimum operation of the septic tank.
Step 4 : Tipping of the dewatered sludge
Relative reduction of environmental substances
When we benchmark the KSA system towards the EU requirements for a wastewater treatment plant, the KSA system performs brilliantly compared to the table mentioned below.
Absolute requirements - reductions of environmental substances
Apart from the reduction requirement the authorities also make demands for absolute values that may not be exceeded. When we as an example look upon the requirements that are made for sludge dewatering of septic tanks you can take paradigm for tender material, “Rørcenteranvisning” 010 of March 2006 as starting point which make the following requirements:
- The dewatered sludge must have a total dry matter content of min. 15 % (according to DS 204)
- Suspended matter (SS) max. 150 mg/l
- Ammonium nitrogen(NH4-N) max. 100 mg/l.
The concentration in the material that has to be treated is of great importance to the fact whether you can observe the requirements that are made for the treatment, due to the fact that it is not possible to treat (reduce) over 100% in one process. From the table mentioned below you can conclude the max. values in inlet in order to live up to the requirements from the Department of Environment. In cases where the contents of environmental substances in the inlet are too high and cannot live up to the requirements from the Department of Environment you can use an additional treatment process, which can be delivered together with the equipment.
Practise documents that the KSA-system lives up to the above-mentioned theory concerning reduction.
