Abstract
Liquid wastes are disposed of by intimate mixing with clay to form a slurry, paste or cake product and disposing of the product into impervious pits. Preferably the process is operated on a clay site so that the site provides a pit which is impervious merely by excavation and the excavated clay can be used as a feed product to take up the liquid waste.
Description
SPECIFICATION
Disposal of liquid wastes
This invention relates to the disposal of liquid wastes, which term includes sludges.
Waste disposal of liquids usually involves greater problems than waste disposal of solids owing to the ability of liquids to escape from any nominal containment with the risk of environmental pollution.
Thus it is seen for example that waste disposal sites are frequently only licensed for the disposal of solids. To dispose of liquids a licence incorporating more stringent conditions is required. This both limits the number of sites available and increases the cost of disposal. The disposal usually involves the provision of interceptor tanks in which the liquids are treated, such as with lime, to deposit solids. The liquid is then disposed to drains (where this is acceptable) and the solids scraped from the tanks and used as land in-fill or otherwise disposed of.
In accordance with the present invention a process for the disposal of liquid wastes comprises taking the wastes into clay by intimate mixing to form a substantially homogeneous slurry, paste, or cake product and disposing of the product into impervious pits.
The process of the invention is preferably used at clay sites. Clay can be excavated to produce a disposal pit and the excavated clay used to take up liquid wastes and then be used to refill an excavated pit. Waste-containing product can be put down in layers with interlayers of other forms of waste such as domestic waste or with sealing interlayers of tar, pitch, or concrete.
The invention has application to the disposal of aqueous and organic wastes such as oils. In general clay shows an ability to take up its own volume in water before separating into two phases. If the liquid wastes contain acids then some take up in the clay tends to be lost but even at 20% take up by volume the process can be advantageous. If the mixed clay and waste has a large surface area exposed then there is a tendency for evaporation of the liquid to take place. So long as the waste does not contain objectionable solvents such evaporation does not cause any problems and in fact acts to reduce volumes slightly.
Intimate mixing of clay and liquids may be achieved in a number of ways, In a preferred way excavated clay is rendered into crumbs and fed into a pug mill together with the liquid waste until a slurry is formed. Both the clay crumbs and the waste can be measured by volume or by weight converted to a volume so that an appropriate ratio is created in the output from the pug mill. Depending on the nature of the clay and the liquid wastes adjusting constituents may be added either to the clay or to the liquid wastes. For example, plasticiers, pH modifiers and surfactants could be added but as a main objective is cost saving a simple sole mix of clay and liquid is looked for.
The output from the pug mill is carted to an excavated pit or trench (typically about 12 meters deep) and deposited as a layer about 15cm deep.
This can be exposed for about 7 days and then covered with a 30 cm layer of domestic refuse. A further layer from the pug mill is then deposited and so on until the pit is full. It is then capped.
1. A process for the disposal of liquid wastes comprising taking the wastes into clay by intimate mixing to form a substantially homogeneous slurry, paste, or cake product and disposing of the product into impervious pits or trenches.
2. A process as claimed in claim 1 operated on a clay site in which clay excavated from the site to form the pits or trenches is used to mix with the liquid wastes.
3. A process as claimed in claim 1 or 2 in which the liquid wastes are aqueous.
4. A process as claimed in claim 1 or 2 in which the liquid waste is organic such as oil.
5. A process as claimed in any preceding claim in which the product is exposed for a period prior to adding more product or another solid waste.
6. A process as claimed in any preceding claim in which adjusting constituents are added.
7. A process as claimed in any preceding claim is disposed of in layers with other solid wastes such as domestic waste.
