Waste aq. sludge is converted to a solid, friable and odour-free prod. by treatment with Ca oxide. The sludge is supplied to a treatment zone at a first rate while the Ca oxide is supplied at a second rate releated to the first so that when the sludge and Ca oxide are mixed an exothermic reaction occurs with the evolution of steam to form the desired prod. having pH >=12. The sludge and Ca oxide are introduced at the desired rates to one end of the treatment zone along which they are moved concurrently at a rate such that the reaction has effectively terminated by the time they reach the other end of the zone. The prod. is removed from this end of the zone and the steam is withdrawn. The method may be used to treat either oil well pumps, sewage sumps, or sludge dredged from the bottom of a lake or harbour. The pH value and the heat produced in the treatment zone deactivates any virus or bacteria present in the sludge. Similarly soluble toxic compounds initially present in the sludge are ...

Greywater Recycling System

Номер: US20160016836A1
Принадлежит: GREEN WATER INNOVATIONS, L.L.C.

A greywater recycling system. The system is designed using flow control management and minimally-sized holding tanks allowing use of on-site greywater recycling in locations where conventional greywater recycling systems are unsuitable. Where conventional greywater recycling systems produce low-value recycled water suitable for use in irrigation, the system produces high-value recycled water suitable for use in other systems, such as cooling towers with minimal impact on the facility and changes to existing processes. By using higher capacity extraction, reducing the size of storage tanks, and returning permeate to supply the extractor, as needed, the system operates efficiently while with a greywater source producing a non-continuous flow of greywater being modular and compact.
