Management of effluents and waste from pharmaceutical
tive wastewater treatment plants. Effluents, generated in the production lines of antibiotics, were collected at three different times of the year and also before and after the treatment plant effluent. Both produce a wide variety of drugs, among them antimicrobial drugs (antibiotics) and both have an Effluent Treatment Plant (ETP) prior to dis-
A study performed by other researchers (Shi et al. 2016) confirmed high COD removal efficiency (83%) from paper mill wastewater, in coagulation treatment, indicating that, the initial pH of the effluent had a tremendous effect on the COD removal (Choudhary et al. 2015).
Treatment of Tissue Paper Wastewater: Application
wastewater treatment, COD. I. INTRODUCTION. High consumption of freshwater is one of the most important environmental concerns in the paper industries [1]. Effluents of the pulp and paper industry contain a number of toxic compounds and may cause deleterious environmental impacts upon direct discharge to receiving waters [2]. The pulp and paper
Having examined the issues related to the various phases and technologies involved in algal biodiesel production coupled with wastewater treatment, we turn to the core of this paper, the economic prospects for biodiesel production from algae-based wastewater treatment in Brazil. a) Yield of biodiesel from wastewater.

Anaerobic wastewater treatment plant to provide energy for paper producer. VIENNA & ORTMANN, Austria, Feb. 16, 2011 -- Swedish paper-maker SCA Hygiene Products has commissioned the building of an anaerobic wastewater treatment plant at its Austrian SCA site in Ortmann...
The Use of Polymers in the Flotation Treatment of Wastewater
The use of flotation for the treatment of wastewaters in general, but especially for the removal of oil, grease, general organic matter, and suspended solids, is well established as a low energy process. Polyelectrolytes (PEs) can enhance performance without adding to the solids load that occurs with inorganic additives such as alum. The bridging of pollutants and the attachment of the
Urban water systems and, in particular, wastewater treatment facilities are among the major energy consumers at municipal level worldwide. Estimates indicate that on average these facilities alone may require about 1% to 3% of the total electric energy output of a country, representing a significant fraction of municipal energy bills. Specific power consumption of state-of-the-art facilities

The high efficiency of the wastewater treatment system helps to reduce the environmental footprint of forward-thinking companies like PANASA. The savings produced by replacing fossil fuels will ultimately cover the entire cost of the wastewater treatment plant and then go on producing profit for the client.

- Can polyacrylamide be used as a thickener in water-based fracturing fluids?
- Polyacrylamide (HPAM) is commonly used as a thickener in water-based fracturing fluids due to its good solubility and thickening ability. However, drawbacks such as the formation of high temperature and high salinity in oil and gas production currently limit its use as a thickening agent for fracturing fluids.
- Which polymer thickening agent is a cationic polyacrylamide?
- Zhang et al. , synthesized the polymer thickening agent DXGY-1, which is a cationic polyacrylamide. Its viscosity retention ratio in 12% HCl + 3% HF reached 82%. Liu et al. , synthesized a copolymer from AM, DMDAAC, and AMPS monomers and a cationic monomer X.
- Which polymer is used as thickener in the presence of Ca2+ or Na+?
- Hydrophobic-associated polymer is widely used as thickener in the presence of Ca 2+ or Na +. Three polymers including partially hydrolyzed polyacrylamide (HPAM) and hydrophobically associating polymers (CHAP and CBHAP) were used to clarify the thickening mechanism.
- What are acrylamide and polyacrylamide used for?
- Acrylamide and polyacrylamide (PAM) are used in diverse industrial processes, mainly the production of plastics, dyes, and paper, in the treatment of drinking water, wastewater, and sewage. Besides inorganic form, acrylamide is formed naturally in certain starchy foods that were heated to cook a temperature above 120 °C for elongated time.
