On-Site Treatment of An Antiparasitic API in CIP Rinse Water to Eliminate Off-Site Disposal - Case study
Customer Pain Point A US pharmaceutical manufacturing plant generates several hundred thousand gallons per year of cleanin-place (CIP) rinse water contaminated with an antiparasitic active pharmaceutical ingredient (API) and organic solvents. The stream was historically trucked off-site for incineration because the API is ecotoxic and cannot be discharged to sewer. The site experienced periodic ...

Default Guideline Values (DGVs) For Toxicants When Assessing Water Quality
Default Guidelines Values (DGVs) are developed according to risk assessment principles by using data derived from laboratory tests in clean water. The species sensitivity distribution (SSD) method is used in deriving DGVs for toxicants during water quality assessment. In circumstances where SSD is not applicable, the assessment-factor approach is used. It provides the best estimate of toxicant ...

Probability of Aluminium Toxicity from Bhandup Complex Water Treatment Plant, Mumbai
Abstract Bhandup Complex water treatment plant located in Mumbai, India, supplies water to most of Mumbai. The plant receives raw water from Vehar Lake. Alum has been used as a coagulant in the treatment process for the past 27 years. The backwashed water from the plant is released into Vehar Lake, which carries a significant amount of suspended matter. Therefore, a layer of sludge was deposited ...

Toxicity Characteristics of Drilling Mud and Its Effect on Aquatic Fish Populations
Abstract Toxicity tests are important for assessing the effects of complex chemical mixtures, such as waste drilling mud, on aquatic ecosystems. When waste drilling mud is released into the marine environment, strong ocean currents perhaps separate the drilling mud into a solid phase (SP) and a suspended particulate phase (SPP). A comprehensive assessment of drilling mud and base oil was carried ...

ANZ Guidelines for Fresh & Marine Water Quality
The guidelines for fresh and marine water quality were developed to enforce the proper management of natural and semi-natural water resources in Australia and New Zealand. The latest revision on the guidelines was done in 2018 and is a powerful tool for water managers to assess, manage, and monitor water quality in aquatic systems. Consequently, the guidelines support community values connected ...
