Viridian Systems can treat a range of contaminated waters offering the most appropriate technologies. At Viridian we treat contaminated surface waters, contaminated groundwaters, leachate, composting leachates, industrial effluents and commercial effluents. We also offer a wide range of Consultancy services.
Leachate is highly contaminated water that forms from biodegradation of organic wastes + water soluble waste + rainwater = a chemical ‘soup’ that kills all aquatic life forms and so it must be treated on site or off-site before it can be safely released into the environment. For almost 100% of cases Aerobic Biodegradation is by far the most cost effective process for ammonia removal and additionally:
- Significantly reduces COD, pesticides, metals and suspended solids.
- Removes dissolved methane and odours.
Anaerobic Digestion – Process Water Treatment
Anaerobic Digestion process wastewater generally contains Ammoniacal-Nitrogen, dissolved organic compounds and other contaminants at elevated levels that would typically exceed the trade effluent consent limits imposed by receiving water companies, thus necessitating either export from site via road tanker or pre-treatment prior to discharge into the sewer network.
The economic viability of pre-treatment is determined on a site specific basis but as a rule, the capital cost of constructing a plant should be recouped within a 2-year timeframe and when operating costs are considered, the savings over export via road tanker are considerable. Aerobic Biodegradation is the most cost-effective form of pre-treatment in which Ammoniacal Nitrogen and dissolved organic compounds are oxidised, producing effluent that can, in most cases, comply with trade effluent consent parameters for discharge to sewer without further treatment.
Viridian Systems provides bespoke treatment plants to suit site specific conditions, process wastewater and trade effluent consent limits. Our treatment systems will allow you to comply with ever-increasing environmental legislation targets.
