Anionic and non-ionic surfactants have been detected in the influents to and effluents from wastewater treatment plants (WWTPs). Linear alkylbenzene sulphonates (LAS) and alkylphenol ethoxylates (APEO) are the most frequently detected anionic and non-ionic surfactants in urban wastewater. The aim of this study was to assess the effect of the presence of anionic and non-ionic surfactants in the influent to WWTPs on activated sludge processes.

Anti-androgens entering the aquatic environment, e.g., by effluents from wastewater treatment plants or agricultural settings are contributing to endocrine disruption in wildlife and humans. Due to the simultaneous presence of agonistic compounds, common in vitro bioassays can underestimate the risk posed by androgen antagonists.

The present study was envisaged to check the physico-chemical properties of effluents being treated at CETPs and to isolate indigenous heavy metal tolerant bacteria for their subsequent utilization for heavy metal uptake. Effluent samples were collected from two CETPs located in Ludhiana and Jalandhar and were analyzed for their physico-chemical parameters (dissolved oxygen (DO), biological oxygen demand (BOD), chemical oxygen demand (COD) and pH) and heavy metal profile using Inductively Coupled Argon Plasma-Emission Spectroscopy (ICAP-AES).

The beverage industry effluent was neutral in reaction, medium in electrical conductivity (1.59 dSm-1 ), BOD (42.2 mg L-1 ) and COD (143 mg L-1 ) but low in plant nutrients content. Among the treatments, growth parameters like plant height, head diameter and number of leaves (184.5, 16.1 cm and 32.

Biological treatment aims at using plants and animals to reduce nutrients load and particulate matter in shrimp farm discharge. Although extensive literature is available on the different types of shrimp culture practices, its advantages and disadvantages including the impact caused due to enormous application of chemicals such as antibiotics and use of robotics, he information available on the treatment of effluent in general and biological methods in particular are very scarce.

Constructed wetlands (CWs) have been used to treat various types of wastewaters such as urban runoff, acid mine drainage, municipal, industrial, and livestock wastewaters. This study was conducted to evaluate the effectiveness of two constructed wetlands (surface and horizontal subsurface flows) for piggery wastewater treatment after biogas process. The wetland plant Phragmites australis Cav. was used in two CWs. The flow rate of the CWs was 100 liters/day with the hydraulic retention time (HRT) of 3 days.

Clinical Laboratory produces large quantities of liquid infectious waste in the form of body fluids including blood. Biomedical waste management generally covers the solid waste generated in the Health care set up. Liquid infected waste management in a hospital is mainly addressed in the form of Sewage treatment plant (STP) or Effluent treatment plant (ETP) which is made mandatory for hospitals. Construction of these facilities involves lot of financial expenditure. Small facilities may not be able to afford to construct a STP or ETP in their facility.

The present study was envisaged with the objective to isolate indigenous chromate tolerant bacteria from effluents and their subsequent utilization for chromium uptake or reduction. Samples were collected from two different Common Effluent Treatment Plants (CETPs), located in Ludhiana (sample 1) and Jalandhar (sample 2). In both the samples, chromium was found to be the dominant metal contaminant. A total of 10 morphologically distinct isolates were tested for their tolerance to chromium in terms of minimum inhibitory concentration (MIC) of Cr required for complete inhibition of growth.

The use of industrial waste water for irrigation through drip system has emerged a very important way to utilize its nutrients and removal of its pollutants load by cultivating various crops (tomato, brinjal). An experiment was conducted to evaluate the impact of textile factory effluents (0, 10, 35, 75 and 100% concentration) on germination and some physiological parameters like biomass production, root development in vegetable crop. Plants were raised in small pots in triplicate and irrigated with various concentrations (0, 10, 35, 75 and 100%) of effluent.
