High industrial areas produce large amount of wastewater, with this wastewater containing contaminates that are difficult to treat and hence remove. This wastewater is high in heavy loading of contaminants such as heavy metals, as well as being high in salinity such as in chlorides, TSS (Total suspended solids) provide organic and inorganic debris that wash off impervious surfaces into lakes or streams. These substances affect aquatic life, cause turbidity to reduce photosynthesis, reducing oxygen to biological life and providing transport other pollutants. Furthermore increased organic substances provided from polluted runoff cause oxygen depletion due to their decomposition resulting in increased biological oxygen demand and death of aquatic life. Hydrocarbons are also a constant concern as many are known to be toxic to organisms. Several types of hydrocarbons are commonly found at industrial sites such as naphthalene, phenol, oil and grease. These have a long life as a toxic substance, very mobile and can provide a thin but dense layer covering aquatic life and restricting their life assisting processes. Designing systems that are suitable for the treatment of heavy contaminants, TSS, organic pollutants, hydrocarbons and high salinity is vital as this water is expelled directly into the environment or into sanitary sewer systems.
Common sources of industrial wastewater include:
· Battery manufacturing
· Electric power plants
· Food industry
· Iron and steel industry
· Petroleum refinery
Removal techniques that need to be present in these types of applications include oils and grease removal, solids removal, removal of biodegradable organics and heavy metal removal. The best systems for this type of filtration include a system which incorporates the tertiary as a dissolved pollutants filtration system that can also be incorporated into the surrounding water environments, as well as the need for heavy metal removal, organic removal and hydrocarbon removal. The PROTECTOR systems that are applicable for this usage are the MAXIPROTECTOR, ENVIROPROTECTOR and XTREAMPROTECTORS to remove majority of all dissolved pollutants. This system should also be combined with a gross pollutant trap, the ECOPROTECTOR, and in industrial sites high in oil the system should be equipped with a HYDRAPROTECTOR.
If the industrial site is situated within distance of a natural hydrology and aquatic ecosystem and this environment is where the pollutants is dispelled into, incorporation of natural filtration systems to mimic and increase the filtration that these areas could provide. Our BIOPROTECTOR is extremely suitable for this and with the variations in size of the BIOPROTECTOR available, we can manage any size of wastewater flow.
