Fate and effects of pulp mill effluent solids in the soil environment
The pulp and paper industry in New Zealand annually produces over one hundred thousand dry tonnes of solid waste due to the treatment of pulp and paper mill effluents, the majority of which is currently landfilled. The New Zealand Waste Management Strategy (2002) has set a target for the diversion …

Color Removal From Pulp Mill Effluent Using Coal Ash Produced From Georgia Power Coal Combustion Plants
… ash (CFA) waste from coal power plants, and the effluent generated by pulp mills. Pulp mill effluent discolors surface waters into which it is discharged, and has been proven to negatively impact the dissolved oxygen and carbon necessary for aquatic life. The proposed solution is a cost-effective …

Development of an embryo-larval chronic toxicity test using the sea urchins Tripneustes gratilla and Echinometra mathaei
… of the bioavailable fraction of toxicants in effluents and environmental media, such as water and sediment. Test organisms must be highly sensitive and ecologically relevant. Gametes of the sea urchins Echinometra mathaei and Tripneustes gratilla are used for acute toxicity testing purposes in …

Effects of Land Disposal of Pulp Mill Effluents on Plant Nutrient Uptake and Element Balance
… ascertain the effect that land irrigation with pulp mill effluent has on nutrient uptake and element balance of tree seedlings. Results show that the effluent significantly increased the sodium content of both soil and tissue; however, these levels fell far below the level necessary to become …

Electrolytic purification of water
… production, whether from a bore water supply or effluent from a tannery. Where the contaminants in an effluent are useful they are separated in a specialised electrolyser for re-use in the process that produced the original effluent. The value in doing this exceeds the cost of electrolytic …

The anti-estrogenic and liver metabolic effects of DHAA in rainbow trout (oncorhynchus mykiss)
… acid (DHAA), a resin acid present in pulp and paper mills, may have anti-estrogenic effects in fish. A chronic-exposure toxicity experiment using immature rainbow trout (Oncorhynchus mykiss) was conducted in order to assess the endocrine disrupting and liver metabolic effects of the …
