subject: Importance Of Waste Water Treatment For Pharmaceutical Plants [print this page] Pharmaceutical industries use large quantities of chemicals and biological primary substances in to manufacture medical products. Thus, theirindustrialwaste water contains a wide range of substances that are not easily separated from sewage sludge.
Waste water from pharmaceutical industries poses one of the biggest challenges to industrial water treatment programs. Moreover, due to the highly toxic nature of the primary substances (biological and chemical), it is essential that this water be treated effectively, thereby minimizing the threat of water pollution.
Today, companies specializing in wastewater treatment offer various treatment programs which help mitigate the risk of environmental pollution. Additionally water treatment programs also help in reducing operational costs,minimize the risk of incurring liabilitiesarisingdue to ineffective treatment of production waste, promote sustainable living and improve overall hygiene and safety.
There are many water treatment programs that are designed for pharmaceutical industries. Let"s take a look at a few:
Pretreatment
A host of problems normally arise in biological processes which reduces the efficiency of the plant. In order to prevent such problems, pretreatment systems such as reverse osmosis, clarification, ion exchange and multimedia filtration are employed which result in removal of these pollutants.
Legionella Risk Management
Found in cooling towers, fountains and humidifiers, legionella is a type of bacteria which breeds in natural and manmade water bodies. It survives as a parasite in the host organism. If infected by this bacterium, a person can die of legionellosis, a fatal form of pneumonia. A comprehensive legionella risk management involves the identification of potential sources of legionella, effective water treatment and preventive programs.
Boiler System Treatment
In order to increase the lifetime and efficiency of boilers, prevent scaling, deposition and corrosion, they are treated with various processes such as oxygen scavengers, corrosion inhibitors and polymer formulations.
Wastewater Treatment
This is specifically aimed at treating production waste water and it also helps in recycling water. Processes involved are:
'Odor control programs
'Dewatering solids generated in waste and maximizing cake solids
'Optimizing removal of suspended solids
Cooling Water Treatment
By employing various chemical processes, this treatment helps in prevention of corrosion, scaling and deposition in the cooling towers. Further, cooling towers are breeding grounds for microbial growth, which if not removed, form a layer of bio-slime, a natural adhesive for scale formation. If not treated at regular intervals, towers tend to accumulate unwanted material and thereby decrease in efficiency.
Thus, in order to minimize the threat to the environment, it is essential for pharmaceutical industrials to implement an effective industrial waste water treatment program.
