Water

Water is life. It directly sustains humankind and its developmental needs. Water plays infinite roles in our day to day life with abundant applications. According to the specific end use of water, one needs to set its desirable characteristics. Here we enlist a few applications that need certain quality parameters to be tested.
To ensure that a boiler runs properly over its lifetime, treating the water that circulates within the system is important. In absence of desired quality of boiler water and feed water, boiler's useful life will be significantly shortened. Resulting from untreated water, the boiler overheats and fails to produce hot water or steam in requisite quantity and results in overall loss of efficiency.

Unconditioned boiler feed water even though coming from a municipal water supply, can contain dissolved salts and form scale on the heat transfer surfaces as the water is heated. This deposited scale drastically reduces the heat transfer of the boiler and leads to overheating, tube failure and efficiency loss. Scale also reduces the flow area, which increases the pressure drop in boiler tubes and piping, resulting in low steam volume and downstream equipment failure. For an effective water treatment programme, one needs to check the boiler water quality from time to time from an outside lab.

It is recommended that water from each source shall be got tested before the commencement of construction work and with appropriate frequency thereafter till the completion of the work. Water used for mixing and curing of concrete needs to be clean and free from detrimental contaminants of alkalis, acids, oils, salts, organic materials, vegetative growth or other substance that may be deleterious to bricks, stone, concrete or steel. Generally potable water is considered satisfactory for mixing. Here are some parameters that are required to be tested as per the standard.

Cooling towers use evaporative cooling system for controlling process heat. Proper water treatment program is essential for safe operation and life extension of equipment. For an efficient operation of a cooling tower, generally three main factors need to be controlled
Cooling Tower Water Treatment in pune
  • Corrosion
  • Scale Formation
  • Biological Fouling
As the water evaporates, the dissolved solids originally present in the water remain behind and need to be meticulously controlled, besides bio-contamination. This can lead to corrosion, scale or biological fouling which may negatively affect heat transfer as well as the longevity of system components.

Sometimes we face problems with usable water. Water appears cloudy or coloured, plumbing starts corroding faster, water has foul smell or tastes odd, clothes washing starts giving stains or the soap does not foam much. It is the time we must get water checked. More importantly, when the health related problems, especially gastrointestinal illness, are visible, we need to rush water for testing. Here are a few important tests that Polytest Laboratories offer serving all the practical purposes.

The quality of dialysis fluids is too often a neglected problem at many renal healthcare centers. Every week, haemodialysis patients are exposed to about 400 lit water for the production of dialysis fluids which come into direct contact with the bloodstream. It is, therefore, clearly vital to monitor the chemical and microbiological purity of dialysis water. Not only the final dialysis water quality but also the quality of water at various stages of purification system needs to be monitored. As there is always a risk of chemical contamination due to primary pollution of municipal water, whereas the problem of microbiological contamination lies across the stages of entire treatment, distribution and point of use.

Water recycling is a key to the sustainable future. It indirectly conserves drinking water used for non-critical applications. Recycled water is effectively used for non-potable purposes, most commonly for agriculture, landscape, parks, industrial cooling and process water, toilet flushing, dust suppression, construction activities, concrete mixing and recharging of artificial lakes.

Wastewater recycling pays as it addresses two problems simultaneously:

ONE: Treatment for compliance and arresting the environmental pollution; and
TWO: utilization of same after purification for a lot many gainful applications saving freshwater costs.

Typical tests for recycled wastewater are those required for statutory compliance with a few additional ones to ensure enhanced quality for recycling purpose.

Pool water sanitation is utterly important to ensure healthy conditions in swimming pools or similar recreational water bodies. Proper sanitation is needed to maintain the visual clarity of water and to prevent the transmission of infectious waterborne diseases. Contaminants added up swimmers can influence the pool water management.

Typical contaminants that decrease the water quality include microorganisms from infected users and body oils including sweat, cosmetics, suntan lotion, urine, saliva and fecal matter.

Additionally, the complex reactions between disinfectants and water contaminants can produce a mixture of chloramines and other byproducts. Pathogenic contaminants, i.e. microbes pose greatest hazard to the users leading to recreational water illnesses. Typical pathogens are viruses, bacteria, protozoa and fungi. Diarrhea, Cryptosporidiosis and Giardiasis are the most commonly reported illness associated with pathogenic contaminants, while ear, skin rashes and respiratory infections are also common.

Key to a well maintained pool is timely and thorough testing of feed and pool water.

Environmental Quality


Broadly, our environment consists of the air, water, and land that make up the planet, the plants and animals along with all other living beings. We also need to consider the built environment – the environment we create for ourselves – and how it affects our health and comfort and also the wellbeing of the natural environment; natural resources; and the aesthetics. All of these need to be considered when we examine protecting environmental quality interrelated with pollution levels and human exposures.
To ensure that a boiler runs properly over its lifetime, treating the water that circulates within the system is important. In absence of desired quality of boiler water and feed water, boiler's useful life will be significantly shortened. Resulting from untreated water, the boiler overheats and fails to produce hot water or steam in requisite quantity and results in overall loss of efficiency.

IEQ refers to the quality of a building’s environment in relation to the health and wellbeing of people occupying it. IEQ is determined by many factors and contaminants impacting health conditions of the building occupants often leading to a sick building syndrome.

Various respiratory symptoms and illnesses can be associated with sick building characteristics, including dampness, cleanliness, and ventilation characteristics. Indoor environments are highly complex and building occupants may be exposed to a variety of contaminants such as various gases and particulates emanating from office machines, 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.

Municipal solid waste (MSW) is a heterogeneous refuse from households, non-hazardous solid waste from industrial, commercial and institutional establishments, market waste, yard waste and road sweepings. It poses a great health and environmental hazard and needs to be scientifically managed in terms of collection, transfer, treatment and disposal.

Effective MSW Management depends upon an appropriate distribution of responsibilities among many stakeholders including local self-government. Like all the waste management strategies, MSW also first needs to be fully characterized over all the seasons and localities.

Fuels, Lube oils & industrial fluids


Fuels and lubes are invaluable hydrocarbon derivatives and the drivers of industrial revolution. They are of several types with innumerable applications, each one with distinctive characteristics. To keep the prime movers and machines in top working conditions, characteristics of fuels and lubes must be maintained in healthy working range, and therefore, they need to be tested with definite frequency. The knowledge of the fuel properties helps in selecting the right fuel for the right purpose and efficient use of the fuel.

The following characteristics, determined by laboratory tests, are generally used for assessing the nature and quality of fuels. Industrial fluids are also of organic and inorganic nature or the blend of both designed for various secondary industrial applications such as for metal working, mechanical power transmission or heat transfer.

The function of the oil in transformers is to cool and insulate. Transformer oils are subject to electrical and mechanical stresses while a transformer is in operation. In addition there is contamination caused by chemical interactions with windings and other solid insulation, catalyzed by high operating temperature. The original chemical properties of transformer oil change gradually, rendering it ineffective for its intended purpose after many years. Oil in large transformers and electrical apparatus is periodically tested to make sure it is suitable for further use.

Soil, Fertilizer & Compost


Soils are complex terrestrial ecosystems that are host to a variety of interactions between physical, geochemical and biological processes. Fertilizers and composts make a unique contribution to integration and improvement of complex soil systems suitable for biotic propagation. We need to put soil system to best use for human activity and hence need to have a deeper understanding of soil put for various purposes. Testing of various soil parcels makes it possible to take a practical benefit of technology at field level.
The distinction between Fertilizer and compost is that Compost feeds the soil and fertilizer feeds the plants. Fertilizer adds to the soil's nutrient supply, but instead of feeding the soil food web, the ingredients in fertilizers are intended to meet the needs of fast-growing plants. Fertilizer can be natural or synthetic, whereas compost results from a controlled biological decomposition of organic material.

Compost is sanitized and stabilized product beneficial to plant growth. It contains plant nutrients but is typically not characterized as a fertilizer.

Soil is a natural body and is considered to be the "skin of the earth. It contains mineral, organics and live microorganisms. Soil performs important functions such as being a medium for plant growth; means of water storage, supply and purification; as a modifier of earth atmosphere and a habitat for organisms.

To understand the suitability of soil with respect to farming fertility and other aspects and to work out soil improvement plan, the first step is to test soil for target parameters.
