Clean air is a fundamental requirement of human health and well-being. However, rising air pollution poses a significant threat across the world. The majority of the urban population is exposed to diseases due to air pollution.
A legislative framework has long been established for the Air quality standards, both ambient air and for the workplace, which need to be maintained for the population’s well-being. For this frequent monitoring of air needs to be done to understand the changing pattern of the pollution load.
Effluent Treatment Plant or ETP plays a very important role for treating the wastewaters and making them reusable for a safe discharge in to the environment or recycle it for useful application withing the processes.
Careful sampling and analysis of wastewater is essential to find out the treatment solution or to design a system to purify it for the desired standards. It is also tested periodically to keep a check on treatment plant efficacy and make necessary corrections in the processes.
IEQ refers to the quality of a building’s environment in relation to the health and wellbeing of occupants.
IEQ is determined by factors and contaminants impacting the health conditions of the occupants leading to a sick building syndrome.
Various respiratory symptoms and illnesses can be associated with sick building characteristics, including dampness, cleanliness, and lack of ventilation.
Indoor environments are highly complex and depend on a variety of contaminants such as gases and particulates emanating from office equipment, cleaning products, construction activities, carpets and furnishings, perfumes, cigarette smoke, water-damaged building materials, microbial growth (fungal, mold, and bacterial), insects, outdoor pollutants and many other factors.
Understanding the sources of indoor environmental contaminants and controlling them can often help prevent or resolve building-related worker symptoms.
Micrometeorological parameters play an important role for the prediction of pollution dispersion modelling within the surface boundary layer. It also helps form baseline of ambient parameters through various seasons in establishing industrial activity.
Municipal solid waste (MSW) is a diverse mixture of refuse from households, non-hazardous solid waste from industrial, commercial and institutional establishments, market waste, yard waste and road sweepings.
It poses a tremendous health and environmental hazard and needs scientific management and disposal.
Like all the waste management strategies, MSW also first needs to be fully characterized over all the seasons and localities to be able to devise a scientific disposal approach.
Noise level measurement is the most important part of workplace monitoring. Constant exposure to high noise levels can adversely impact hearing and create many nervous disorders.
Polytest Laboratories helps identify noisy hotspots, measures noise levels and provides easy to understand reports.
Water recycling plays a vital role in a sustainable future. It indirectly saves drinking water being used for non-critical applications.
This recycled water can be effectively used for non-potable purposes such as agriculture, landscape, parks, industrial cooling & processes, toilet flushing, dust suppression, construction activities, concrete mixing and recharging of artificial lakes and a host of other gainful applications.
Wastewater treatment and recycling solves two problems simultaneously:
These are National Regulatory Standards for wastewater discharged to surface waters.
In the context of pollution levels of surface water, the quality of the same needs to be controlled by regulating surface runoffs and pollutional discharges, since these water sources are mostly used further for agriculture, drinking, bathing and industrial purposes. CPCB has regulated the end-use of surface water according to its quality criteria.
Sewage and sullage are generated from household activities and other domestic usage of water. As sullage weakens wastewater and is generated from non-toilet usage of water, such as bath or handwash, it still contains microbial and organic, inorganic pollutants.
Therefore, both types of wastewater need to be tested for their respective treatment approaches and generally following parameters can give their characteristics.
Due to poor lighting the quality of work and productivity gets affected, especially in the circumstances where precision is required.
Insufficient or excess brightness can strain the eyes and cause headaches and discomfort. This leads to mistakes at work, affecting quality and productivity.
Based on results of ventilation survey in industries, homes, schools, or offices, the experts can design necessary modifications to enhance efficacy of the ventilation and thereby indoor air quality.
People productivity can be greatly improved by improving the quality of indoor air.
