The conference on sewage treatment technology featured National papers on advances in wastewater treatment and sludge management technology in the participating NATO countries.
Highlights of the conference included: A Canadian report on improved control of sludge dewater- ing and on conversion of sludge to oil; Italian advances on control of toxic metals and innovative anaerobic treatment of wastewaters; Dutch studies on toxics removal and disposal of sludges; Norwegian advances in sludge management, nutrient control and septage handling; British advances in sludge digestion and improved manage- ment of wastewater treatment plants; and American advances in wastewater treatment and sludge management related to control of pathogens and toxics.
The contents do not necessarily reflect the views of the Agency and no official endorsement should be inferred. A new concept in automated control of the conditioning and dewatering of sludge using rheology as the control approach optimized the dewaterability of sludge while minimizing the cost of polymer addition.
The control strategy used a computer algorithm which correlates the Theological properties of the sludge measured by a viscometer with polymer demand. The viscometer and polymer feed pump, interfaced to the computer, were successfully used by the control algorithm to automatically adjust the polymer flow rate.
In a second approach, the conversion to sludge to oil has been developed at batch and continuous pilot scale as an attractive alternative to the sludge disposal options currently in operation. The process was stable with typical oil yields of The oil viscosity under optimum operating conditions was The problems of sludge disposal are expected to intensify in the future due to a number of factors.
The total cost of sludge disposal will increase as the quantity of sludge to be disposed of, increases. The fraction of sludge disposed of by agricultural utilization will probably decrease due to the problem of finding suitable land within a reasonable distance of large population centres.
Potential restrictions on the loading rates for sludges with high levels of heavy metals may also contribute to a decline in this practice. The feasibility of landfilling will decrease as public opposition to the licensing of new disposal sites continues to grow. It would appear that the immediate future in sludge disposal technology will feature a trend towards more complex systems, which also implies higher costs.
This will be especially true for the large urban areas where the impact of the above factors will be most keenly felt.

The Secretary-General of the United Nations is the depositary of more than multilateral treaties which cover a broad range of subject matters such as human rights, disarmament and protection of the environment.
In order to control costs, alternative resource recovery oriented solutions based on either the upgrading of current technology or the implementation of new technology, are needed. The trend has been towards considering sludge treatment from an overall systems design approach.
The incentive for upgrading has been provided by the large increases in energy costs over the last ten years, and the realization of how energy inefficient most incinerator installations were.
