Sewage Water


Sewage Water Testing

Can anyone imagine the life without water? Everybody knows the answer. We uses water our life in many types. Nobody can live without water not a single day. We uses water for drinking purpose, bathing , cooking ,cleaning and many more .At first we talk about for drinking water .There are the many types of waters ,which we used in different –different ways. So we have to need for test the water quality.

Proper treatment of household wastewater is critical in preserving the health of the public and the environment. In unsewered regions, on-site domestic sewage treatment systems (OSDTS) are used to treat household wastewater (sewage).

Types of domestic systems include greywater diversion or treatment, incinerating toilets, composting toilets, and septic tanks. However the most common type of OSDTS is the aerated wastewater treatment system.

Aerated wastewater treatment system
Aerated wastewater treatment system contain a series of chambers where the sewage is treated in stages. The sewage enters the first chamber where the larger solids settle to the bottom forming a sludge layer. The top layer or “clarified” sewage flows into a second chamber where it is mixed with air and bacteria for further treatment. Once all the solid and organic matter has been removed, the treated sewage (effluent) is generally disinfected before being discharged through an irrigation system. Material that is not completely broken down by the bacteria in the system will build up over time and must be pumped out.

Water is a basic need for human survival as well as construction purposes. Life on earth cannot be imagined without water. Water should be pure and free from any impurities as impure water is the prime source of many diseases and hence needed to be tested for the different parameters so as to ensure that it is safe for drinking purpose. Drinking water should tested for solids, hardness, alkalinity and other parameters to make it safe for consumption. Wastewater should also be checked for various parameters such as solids, BOD, COD so as to ensure that it is suitable to be dumped in river and make sure that it does not pollute the environment. Similarly construction water should also be checked for ts suitability to be used in the construction purposes as water having undesirable may DEEPA ENTERPRISES TESTING LABORATORIES conducts the testing of the water and wastewater as per relevant standard and standard procedures:

We can assist owners to meet this requirement by:

- collecting and analysing the aerated wastewater treatment system effluent
- providing a laboratory report
- If you prefer to collect your own sample, we can provide you with the appropriate sample containers, a sterile bottle for the Thermotolerant coliform test and a non-sterile plastic bottle for the BOD5 and suspended solids tests. Sample containers are free and can be collected from our laboratory.

With our company origins in the effluent industry we remain a leading provider of influent and effluent analysis for a wide range of treatment plants
We provide assistance to effluent treatment plant operators and owners, and because all consents are different, we have developed a wide range of test types to cover them. This ranges from the characterisation of influent, through the process to the final effluent quality, and also includes sludge and air quality tests.

Process control including Influent & Final Effluent Characterisation
DEEPA ENTERPRISES TESTING LABORATORIES offers assistance to treatment plant operators by analysing process samples for a range of different parameters. This may be

- Biochemical Oxygen Demand (BOD)
- Chemical Oxygen Demand (COD)
- Dissolved Oxygen
- Metals
- Nitrate
- Nutrients to check the efficiency of a nutrient removal plant
- Oil and Grease to check for saponification
- Sludge Volume Index
- Suspended solids
- Volatile Solids
- Biofilters
- Biofilters are organic odour reduction beds, but require maintenance to perform at their best. This usually requires regular addition of water, pH buffers, and nutrients.
