A sufficient coagulant dose is essential in order to obtain chemically treated humic surface water of satisfactory quality. But it is bad economy to apply too high a dosage just to be on the safe side. Studies at water treatment plants with large variations in the raw water humic content have shown that efficient supervision […]
The relationship between total aluminium concentration and acidity was studied in water from 14 forest brooks. From the individual brook between 10 and 26 water samples were taken distributed over different parts of one to four consecutive years. All samples were taken during the period 1982-1986. For the whole material pH varied between 4.1 and […]

The mobile septage dewatering trucks are a new alternative to the more common practice for septage handling. The greatest advantage of the system is that the septage is treated at the point of production to the degree that it can be delivered directly to local farmers. Two systems are evaluated; Hamstern by the Mattsson Group […]
