1. We are an apartment complex with 320 families and a Aerobic STP of 1,50,00LPD. We have recently started using STP treated water into toilet flushing. Since same water is re-circulated repeatedly, I am concerned that URIC ACID concentration will get higher over a period of time as it never gets eliminated but keeps building up. I fear this may lead to fowl smell in toilets eventually. Please elaborate on this aspect, how to measure URIC ACID, how to reduce it etc. 2.

My borewell is located near to the compound wall. After few days of borewell drilling sewage started to get collected on the nearby plot which is hardly 3 feet from the borewell. We drilled for 200 feet. Water levels in the nearby borewell are < 50 feet. We used casing pipe for 35 feet after that pipe didn't go. Once the water collected in nearby plot the water level in the borewell raised. The level of water in the borewell is almost same as the outside sewage water. When we run the motor the water level in the borewell didn't reduced.

A new technique makes use of minuscule particles of the yellow metal and their property to change colour in the presence of metal particles such as lead.

Gold, the favourite metal of Indian women, is increasingly becoming popular among scientists as well, though for a different reason. A group of Indian researchers has used gold nanoparticles to develop a simple method to detect lead in wastewater.

The new technique makes use of specially-produced minuscule particles of the yellow metal, and the property of gold nanoparticles to change colour when they ‘bunch-up’ in the presence of metal particles such as lead because of their optical properties.

Heavy metal poisoning is a growing concern in many parts of the country. A new method for removing chromium-6, a highly toxic heavy metal, from waste water has been developed by a group of scientists from India and Ethiopia. They claim it to be low-cost and safe.

The new method uses water hyacinth, a weed known for its ability to spread rapidly over water bodies. It is used for cleansing polluted water bodies owing to its remarkable capacity of absorbing pollutants.

Hi i am working for a project in ETP. Our effluent contains a TDS of 3000 ppm while after equalisation - that is after addition of lime and alum - our TDS increases to 4500 ppm giving our outlet TDS to be 5000 ppm. In this project we haven't installed any tertiary process. It consists of simple equalisation tank, primary clarifier, surface aeration , secondary clarifier followed by sand filter and carbon filter. after addiiton of lime our ph is 11.5 and after addition of alum we maintain a ph of 10.5. Please suggest me some solution for this problem.
