The Feasibility of Treating High Concentration
The Feasibility of Treating High Concentration Ammonia Containing Wastewater Using Anammox Process/Full-Scale Anammox Plant Running in Guangxi Province, China Conference Paper (PDF Available
Air stripping was adopted to treat nickel ammonia complex ion-containing wastewater in order to remove nickel and ammonia simultaneously in one technological process.
TREATMENT OF AMMONIA IN WASTEWATER AND LEACHATE
for wastewater with a low ammonia concentration (<30 to 40 mg/L ammonia). Discharge to POTW. If a Publicly-Owned Treatment Works (POTW) that uses biological treatment is locally available, and will allow the landfill or industrial facility to discharge their leachate or wastewater, this option is often the least expensive.
used to lower the ammonia content of a wastewater stream. Some wastewaters contain large amounts of ammonia and/or nitrogen-containing compounds that may readily form ammonia. It is often easier and less expensive to remove nitrogen from wastewater in the form of ammonia than to convert it to nitrate-nitrogen before removing it (Culp et al., 1978).
Shortcut Nitrification Treatment of High Strength Ammonia
Aerobic granular sludge technology is regarded as a promising wastewater treatment process for ammonia nitrogen removal [1]. Granular sludge exhibits desirable characteristics, such as a good sedimentation property, high processing efficiency, high sludge concentration, and a strong resistance to shock loads [7, 8].
3. Ammonia Stripping Application in Industrial Wastewater Treatment. To date, ammonia stripping pilot-plants have been employed to treat various types of wastewater containing high concentrations of ammonia and toxic compounds, such as that derived from secondary effluent of municipal wastewater treatment plant [], animal manure [], and landfill leachate [].
Treatment of Wastewater Containing High Concentration
The simulant wastewater containing high concentration ammonia-nitrogen was treated by electro-chemical oxidation process in intermittent experiment. The influences of different factors including plate distance,current density, chloride ion concentration and initial pH on ammonia-nitrogen and total nitrogen removal were studied.According to the results of the test, the optimal reaction

CN102107977A - Method for recycling wastewater containing
The invention discloses a method for recycling wastewater containing high-concentration ammonia nitrogen, belonging to the field of recycling of organic wastewater. The method comprises the following steps: carrying out a stripping-adsorption purification process on nitrogen-containing high-concentration organic wastewater to strip high-concentration ammonia nitrogen (higher than 90%) out of
The high concentration of ammonia is poisonous to aquatic organisms and, when inhaled or consumed, it can cause death to humans and other animals. With the advancement in technology, there have been various biological and chemical wastewater treatments meant to address the problems with ammonia in wastewater.
Shortcut Nitrification Treatment of High Strength Ammonia
Wastewater containing high concentration ammonia nitrogen was treated by Yu et al. under a 12 h operation cycle; when the ammonia nitrogen concentration in the influent was 600 mg/L, the ammonia removal ratio was 71.3% [1].
Operators of wastewater treatment plants that suffer from high ammonia levels come to us for solutions. We use microorganisms to oxidize ammonia to nitrate. Our VitaStim Dynamic Duo is specifically adapted to work with your entire system, taking into account the chemistry you use, any physical limitations of the plant, and the present
- Can polyacrylamide copolymers be used for flocculation?
- Some successful flocculants based on polyacrylamide copolymers can have molar masses of several thousand kg/mol. One example is the flocculation of montmorrilonite clay particles by copolymers of (uncharged) acrylamide and (cationic) N,N,N–trimethylaminoethyl chloride acrylate studied by Durand–Piana et al 1).
- Which coagulants are used in polymer flocculation?
- The dual system used for polymer flocculation was poly (ethylene oxide)/phenol formaldehyde (PEO/PFR) and FeCl 3 -PAM hybrid polymer . It is worth noting that making these extensively used organic coagulants/flocculants , is difficult and costly, which has limited their usage in wastewater treatment.
- What are polymer flocculants?
- Polymer flocculants are water-soluble polymers which can form flocs from individual small particles in a suspension by adsorbing on particles and causing destabilization through bridging or charge neutralization. Polymer flocculants are high molecular weight polymers and have hydrogen-bonding groups and/or ionic groups in the molecule.
